Well, for oil you want an oil that has higher levels of ZDDP (zinc in it. A lot of guys use rotella diesel truck oil in their boats. Some other oils have good amounts of ZDDP in them too, but you certainly don't want an oil with low zinc in it. Oils with low zinc are not good for the motor.

Some like Wix, some like purolator, but there are many good ones to choose from. Frams are cheap filters internally. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Tom isn't exactly correct on the Rotella as all Rotella's are NOT high in ZDDP. Some have been reformulated for the new diesels!!
Napa gold is a very highly rated filter. Tom, Once again, double check your info before posting. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I think you left out a comma Pete. 
Yes, some rotella oils are formulated differently, but the point of posting that link was for him to do some reading. Notice how I left out the weight of oil?

| yes, thank you for not answering my question horkn. i was wondering what weight, brand, etc. people are using and are happy with since im kinda new to inboards. Im asking for opinions. i could read a million different types of pros and cons online, so i'll rephrase my question, what type of oil (weight and brand) are you using in your 351? thank you |

As Tom mentioned, there are several threads on oils. Some with links to interesting facts on the ZDDP. I'd say with members here, it's split 50/50 on ether Rotella straight 30 or Valvolene VR1 20-50. I'm running the VR1 20-50 in all my boats. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

You'd better start reading!!! I have personally seen cam lobes ground to rounds from people using what they thought was good oil on flat tappet engines. Please, DO NOT get caught up with the marketing/advertising scam and the "bling" factor. Do your research first.

After doing some more searches about ZDDP and flat tappet motors, it appears that the new rotella diesel oils are around 1200 ppm of zddp, about 200 ppm les than what it used to have only a few months ago.
Similar stories of valvoline VR1 oil reducing ZDDP levels to less than ideal numbers have been reported as well by race engine builders. Here is one guy's quote regarding the VR1 in high performance boats. "Case in point, Valvoline Racing oil VR1, had 1300 parts per million of ZDDP in January of 2008 and the last I heard it was down to 900 parts per million just a few weeks ago. Be aware that most racing oils are designed for short term use before being changed out and may lose the additive package before the next oil change in your boat." Castrol has several oils that meet the ZDDP requirements of older motors as well, probably more so than any other brand of oil. As far as actual numbers, the motorcraft 15w-40 has like 1550 ppm of zddp, which is higher than even the old formula of rotella. It appears while some oil makers might make it more difficult to find a proper oil for us, that other brands are making oils specifically for flat tappet motors.

Yeah, some of the stuff that has been posted recently is old news and not accurate anymore.
A lot has changed since that ford article that keeps getting linked was written. I hope people don't simply assume that their VR1 or rotella is the same formula as it used to be, because it is not anymore. It used to be that the new oil was better in every respect than the old oil, and the new stuff can be used on old engines. Unfortunately this all changed in the last couple of years and using the newest oil formula may do more harm than good on these old tech motors. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Very good discussion here. I just bought a 91 SN about a month ago, and the seller told me that he always changed the oil each year with Mobil 1 Synthetic oil. I'm not sure what weight he used, he didn't say. However, I do have some experience with building racing engines (Chevy's ... real engines... :-p )with a freind with decades of experience. We have seen guys' flat tappet cam lobes wiped out as well on break in by using Walmart or Dollar General cheap oil because of the dropping of zinc in oils these days.
What are your opinions on my boat having synthetic Mobil 1 in there right now? Supposedly he put this oil in each year for years and years. I'm driving back home from Maine next weekend to use it and I'm wondering if I should be freaking out about it now that I've read these Ford engines are sensitive to the zinc in the oil. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=5240&sort=&pagenum=1 - '91 Ski Nautique |

Personally, not knowing specifically which M1 is in there now would scare me. The 15w50 has a ton of zinc and would be just fine- but the regular blends have much less. Might want to try and find out what exactly it is that youve got... or switch it out for peace of mind. ------------- |

Can you buy ZDDP as an additive? ------------- Tim D |
Posted By: horkn
Date Posted: July-26-2010 at 2:45pm
Sure you can. ZDDP plus is one of the ones that seems to be pretty prevalent if you search the internet for info on ZDDP. I bet autozone, advance and all those have some ZDDP additive for sale. As an additive to oil that may be lacking ZDDP, it will work, but is more expensive than simply buying an oil with good amounts of ZDDP in it to start with. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Skyway, what exact Mobil 1 oil was used? Some formulas of mobil 1 were good to use even in wet clutch motorcycles.
Basically, if the container has the shield on the back with the "energy conserving" label in it, it won't be good for our motors. Pete, for wet clutch bikes, this is pretty much the rule as well. Waterdog, you have access to the equipment to do the analysis? Do you work for Blackstone or whatever that place is called? In any case, I am very interested. From all the articles I read, even more than I posted, the one synthetic oil that has high amounts of ZDDP was redline brand. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Date Posted: July-26-2010 at 9:25pm
Tim, It's interesting you mentioned this. When I first brought up ZDDP to our oil supplier several years ago, the very first thing he mentioned was "STP". Evidently, the zinc and phosphorous has been in that formula since day one. They picked up the fact that powdered zinc added to oils "plating" out the wear surfaces from the very very early oil benders. Also of interest in the metal stamping business, it was common with deep draw stamping problems way back for you to run down to the auto supply and get a couple cans of STP. Mix it up in the lube and the problems went away!!! You may have missed it in earlier threads so I'll mention it again. We can run galvanized or electro galvanized dry through our dies. No lube needed and when you open up the dies you see where the zinc off the galvanized has coated all the shear and form points. very low coefficient of friction and never any galling. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I'm by far an expert on these motors but as we were discussing my cam (in my rebuilt/slightly built-up motor) I pulled the spec sheet from Cam Research and at the bottom it states...
(USE VALVOLINE 20-50 RACING OIL ONLY) so take it for what thats worth. |

Gun Driver, I wonder if cam research is aware that Valvoline has reformulated their VR oils recently and part of that apparently is lowering of the ZDDP levels. I would love to see what new VR oil has for ZDDP levels. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

I am ready to fill up my 302. The decal reads to use 10W 30 Premium motor oil. Are the above the 2 oils to choose from? IS that because of the additives in these oils or because of the age and type of use of the engine?

Just do not put in automotive 10W-30, it has the least of what you need.
Straight 30 Rotella or Delo. I'm not a fan of multi-vis, but pete's recommendation of Vr1 20-50 is sound, especially if your baby deserves the best. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

| As of earlier this year, Mobil 1 20w50 has ZDDP, it's the only grade of Mobil 1 with enough ZDDP. I get it at Wally World with a Motorcraft filter and costs a little less than the VR1 where I am. |

Keep in mind that decal on the engine is real OLD!!  Stick with the straight Rotella or the VR1 and you're ok. The plate on my my 54 says to use only Havolene straight 30 .

Thanks Don and Pete. I understand the additive properties and their benefit. Is the heavier weight used because it stays in between the engine parts longer before draining back into the pan? Provides a thicker barrier between parts while in motion? I am not questioning the collective wisdom just asking questions like my 9 year old.  ------------- "working on these old boats may not be cost effective but as it shows its what it brings into your life that matters" -Roger http://www.correctcraftfan.com/diaries/details.asp?ID=4897" rel="nofollow - 1973 Skier |

I just kinda fell into the 20w50 myself. I've been using Mobil 1 in most everything for about 20 years and that was as close as I could get the numbers to what my last boat called for. I didn't realize that 15w40 is used in diesels so I was always looking in the gas motor section for oil. Turns out I was doing the right thing, just didn't know it for the first 5 years or so.
I'm sure Pete will have a much better thought out reason as to why, I'm intrested to hear it myself. |
Posted By: horkn
Date Posted: August-02-2010 at 2:02am

The main reason the heavier weight is used is because it is made for flat tappet engines. Newer formulas of oil that have the "energy conserving" seal on it typically lack ZDDP and are made for newer tech roller cam OHV or OHC motors. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

I'm using the Shell Rotella 15-40.
The first oil change of the season I used a little bottle of Crane Cams, cam break in oil to get the extra zddp. This time I tried a 15 ounce bottle of STP oil additive, on top of the Shell Rotella, it said ZDDP right on the front. Man, that stuff was thick though, it took a loonnggg time to pour it all in. Is there such a thing as too thick? |

| Not to confuse things, but it's the rotella straight weights that they tout for flat-tappet motors. I don't think the multi-vis ever had the higher zddp. Whether or not the rotella 30 wt still has enough zddp is another issue. Shell's website no longer seems to have this info. That concerns me. Especially when you consider they changed their packaging last year and now call it "T1". Did they reduce the zddp? The VR1 is listed at .14(1400ppm?) on their website and Mobil 1 15-50 is listed at 1300 zinc(zddp?). The VR1 is racing oil and the Mobil 1 15-50, according to them, can be used for racing. Mobil now has racing 0-30wt with 1850 zinc, but that's listed at over $90.00 for 6qts. Looks like we'll all be relegated to racing oils in the not too distant future. Horkn's numbers on motorcraft and maybe castrol make them seem a viable alternative, but I couldn't find specific numbers on those websites. Of course, the question i've never seen answered is how much zddp is enough for a 351w... |

No, you are not confusing things at all. if anything you are clarifying things. Not all rotella grades are good enough for even broken in motors. The formulas have changed, and only straight weights of that oil are possibly OK. We need a new oil zinc level from the new straight weight rotellas as we are not 100% certain those have enough ZDDP in them. Several Castrol oils have the proper amounts, STP has formulas with ZDDP apparently in them now too. Valvoline VR1's now might not have enough ZDDP. Typically you are better off with straight weights and oils that don't have the "energy conserving" seal on them versus any oil that is say 5 or 10w 30. Basically these new formulas should have everyone thinking about the oil they use. What used to be good for ZDDP levels is not positively good enough anymore. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

I use synthetic oil in everything I own from my cars to my motorcycle.
They are best all the way around for any engine. They cost more upfront but they last twice as long. Mobile one is the best. I run a 5w-30wt in my vehicles and a 20-50wt in my Harley. Synthetics dont burn so you wont get carbon deposits inside your motor. They handle heat better and will actually heal leaking seals. I use Fram filters on my motors and have never had a problem with them. Just change it everythime you change your oil. Good luck, Ray. |
Posted By: TRBenj
Date Posted: August-04-2010 at 2:05pm
Im sorry, but it seems as though youre easily swayed by marketing hype. Synthetic has its benefits, no doubt- but to say they should be used across the board in everything with no respect to other important factors (zinc levels when installed in flat tappet motors, etc) is just bad advice. M1 is good stuff, but there are a lot of other synthetics out there that are as good or better, and some of them cost less. For the amount of hours these boats typically see, its just not necessary- and can be downright harmful if the wrong one is chosen. Regardless of whether or not youve had a problem, Fram filters are junk. Do a little research or disect one and find out for yourself. ------------- |

Just the thought of oil leaking before the rear tire while at any speed makes me cringe. I've been using regular Purolators or the PureOnes, and I've never had a reason to switch. The study Pete linked to didn't seem to have an issue with either as well. ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

I guess I shouldnt have generalized my oil filter choice.
I only run a Harley-Davidson filter on my bike, Motorcraft on my boat, and use to run Fram on my cars till this weeks eye opener. I will do some research on my boat oil chioces before my next boat oil change. Thanks, Rasir. |

The Motorcraft filter is a good one. I use this, as well as the Wix (1515 for the Fords). Napa rebrands the Wix as their own (51515). I have used Purolators as well if I cant get to Napa.
I have read that the M1 15w50 still has a lot of zinc, so that may be an acceptable choice. There are several very good conventional oils (Valvoline VR1, etc) that many here use. I use the VR1 20w50 in all of my boats. ------------- |

I wish I had found you guys a long time ago? I've always used the Motorcraft filter thats what it had since day one but have changed oils over the years I switched to synthetic a few years ago castrol but never paid attention to the levels of zinc etc I have under 600 hours on my 89. so is it good to switch back after using synthetic? ------------- 1989 Teal Ski Nautique 1967 Mustang Harris Float Sunfish |

Well at least I "had a dream" that one day my little red boat would purr like a kitten and roar like a lion. I would have rather had the oil leaks than go through the nightmare I am suspended in. ------------- "working on these old boats may not be cost effective but as it shows its what it brings into your life that matters" -Roger http://www.correctcraftfan.com/diaries/details.asp?ID=4897" rel="nofollow - 1973 Skier |

Keegan,
Look on the bright side. That "dream" is becoming reality! Now, to rationalize somewhat on what you've been through, Just consider it a educational experience. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

The thing so far has cost me about as much as a tech degree in mechanics. I am probably getting a better education though! ------------- "working on these old boats may not be cost effective but as it shows its what it brings into your life that matters" -Roger http://www.correctcraftfan.com/diaries/details.asp?ID=4897" rel="nofollow - 1973 Skier |
