The diesel oil's zinc has been redused the last few years as well.
Actualy, some diesels were among of the first to get roller cams. The Detroit Diesel 2-stroke since the late thirties The Allison/GM 6.2 in '82 |

Not quite what most are saying. The biggest issue is the level of ZDDP in the oils being used. There's a general agreement on this site that the higher levels of ZDDP are better for these flat tappet engines as opposed to other oils with lower ZDDP levels. I believe valvoline and Mobil 1 are the 2 most used brands on this site. Wait until you ask about which filter to use.................... |

And regarding synthetic, for the motor oil either is fine as long as change intervals remain every 50hrs For the trans use Conventional fluid only |

Oh we are talking about oil for the engine.....(still using what Zach told me, but that might be based on where it's placed in the shelf😈...Valvoline might be to high to reach LAMO
So while on the topic, I like Fram filter😂 And I use Mobile 1 on the tube for reduced frictionhttps://www.facebook.com/waterskiing.official/videos/1024892440876525/ |

Based on my Correct Craft Operating manual, PCM recommends a straight 40W oil for warm weather operations. The main challenge with this is that there are very few straight 40W oils offered. Other than Shell Rotella T1, I've not been able to locate any straight 40W where I live. I don't mean to be remedial, but the concept of multi viscosity oils is based on cold vs hot operating temperatures. in a 10W-30 multi viscosity oil, the 10W number is the viscosity index of the oil COLD. the 30 number is the equivalent viscosity index of the oil at 100 degrees C (212 F). This is a viscosity index equivalent, as the higher viscosity is achieved by the use of polymer additives. A straight 40W oil is pretty thick when cold and somewhat resistant to flowing. Many will argue that cold engine start-up produces much of the metal-to-metal wear because the oil has drained into the oil pan and now the oil pump has to pump cold, thick oil to wear surfaces. The lighter weight oils will flow faster, pump easier and, therefore, protect the wear surfaces sooner. I operate in spring, summer and fall, so my engine will see start-up temperatures well below 60 degrees F. That is why I use a multi viscosity oil (Royal Purple 20W-50). I don't think that folks simply disregard PCM's oil recommendation. Based on the availability of straight 40W oil, and that there is simply too much evidence that a quality multi viscosity oil will also provide equal engine protection, many owners and mechanics simply don't bother with the straight 40W. Just my 2¢ JQ |

OK. That makes sense to me. Im assuming Valvaline and Mobile 1 have higher levels than the Rotella? Ill just take my chances on the filter! |

I use VR1 because I can easily source it (by the case on sale, I stock up), they publish their ZDDP levels and it's in the range of the weight I want to use. I would consider using 15w40 if they made it, but they don't, so 20w50 it is. Straight 40 is too heavy in the cold temps.
I don't feel like putting diesel oil with no ZDDP documentation in my gasoline engine so Rotella is out. Castrol GTX Diesel 15w40 used to advertise 1300 zinc and 1100 phos but I see it's no longer anywhere on their product data sheet. Lastly, I'm not a synthetic guy so Mobil1 is out. I have not bothered to look into Amsoil, Royal Purple, Brad Penn, etc. The VR1 is doing the job just fine for now. |

Great summary. Exactly why I run 20W-50 in my engine. I don't think brand is as important as making sure you have the right ZDDP levels for your flat tappet engine. |

My engine was built in the 80s. At the time the manual was written it called for an API SE oil. That is long obsolete. Then came SF, SG, SH and by SJ (2001) phosphorus was lowered. Next came SL, SM and we are currently at SN. The letters keep going up although some are skipped. I can't find anything on SL specifics but by SM (2010) phosphorus max is limited to 800.

How often do you change it? Go by hours or every 3 months? |

General rule of thumb for changing oil in our boats is 50 hours or just before you winterize it.

*and
you wouldn't want 40 hour oil sitting in your engine all winter waiting for the next 10 in spring. |

So don't worry so much about the every 3 month argument with VR1 but not a good idea to leave it all winter and then run it? |

Where the *************** did you read 3 months for boat engine oil? READ THE MANUAL AND THE POSTS ON THIS FORUM. Are you trying to be this dense?

I think it was some other racing/classic car forums discussing flat tappet oils. Some were saying the VR1 has less/different additives so it breaks down quicker??? I think they were basically saying because its a racing oil and formulated differently it needs to be changed sooner and many of them did. Not arguing that to be the case, just asking. I hope it's a non issue because I certainly dont want to change it more than I need too! |

I would be very interested to hear ANY first-hand experience from someone who has had a marine engine failure due to using a non-recommended oil.
For an apples-to-apples comparison, oil related engine failure has to have occurred after consistently using the non-recommended oil but following the recommended oil change intervals. Based on the response sample size, we can draw some conclusions as to whether much of the "which oil" discussion is based on fact or opinion. Ford vs. Chevy. Democrat vs. Republican. |

That sounds like the guy buying the Ski Tique with the automotive carb. It hasn't blown up yet why should he bother to change it? Proactive vs. Reactive.
I believe Joe & Pete are aware of a few documented cam failures... |

well somewhere a manufacturer is lying because my truck I bought new I've changed the oil 3x in a hard 173,xxx miles. 50% of that time the low oil light has been on.

Only on modified engines I suspect. That is why it's it's recommended to break in a cam with lighter seat pressure springs and then replace them with correct ones after its broken in but who actually goes thru the work of doing that? Not every owner of a CC,Mastercraft,Supra or insert name here read forums yet you don't see a bunch of boats for sale with bad engines. For the most part it's case of my brother in laws sisters collage room mates fathers great uncle

The manual was written written 16 years ago and the recommended oil isn't even available!!!! Hence why I came to this forum to get "expert advice" in the first place. There are people out there that are still proponents of changing their oil every 3 months with high performance engines (Fords included). I simply asked a freaking question. Can't seem to do that on this forum without getting a smart a** answer! I came to this forum with limited knowledge, lots of questions and a desire to learn. If that makes me "dense" in your book, I'm sorry I've wasted your time and this isn't the resource I thought it would be. If you don't want to answer questions, regardless of how stupid you think hey are, why are you even a moderator???

6 people have given you the answer as to what they do and but you don't seem to listen or believe them. Do you have a Chevy engine in your boat, no you do not but you call the engine converter and ask them,but the last time they had a Ford go thru the door was before the EPA changed the oil specs. Call them back and ask when was the last time they or Ford has done tests on current oil formulations on engines that have been out of production for 15 years---

sorry for the bashing others have done, not all are like that.
As stated before, oil is always a hot topic, just look at the Harley owner sites. I believe any premium grade oil will be just fine. The guy who is building my engine which is an older one with flat tapet cam said to use Rotella so im using it. This is a guy who has built about every engine known to man and has never had one come back to his shop in over 30yrs. I do not see need for synthetic since these engines do not run very hot though it can not hurt. I use amsoil synthetic in my 2 Harleys and 1 honda an also use it in my car. You may want to go to amsoils web site and look at what they recommend for your boat. Their tech line is also very helpful. Its expensive stuff but i think worth it in certain applications. My Vintage Honda Goldwing (1982) is overhead cam with flat tapets. all the vintage bike guys say use Rotella or Chevron diesel, forget the model number. Harley says use Harley Oil but if you cant then use Diesel Oil. (Harley Oil is junk by the way) |

Glen,
Disregard what your manual says regarding changing your oil every three months. The magic number is 50 hours. If I were you I'd: 1) Change your oil every 50 hours or at the end of your boating season before you lay it up. 2) Use a brand you are comfortable with, but regardless of brand make sure the oil has a high level of zinc (ZDDP of 1400). 3) 20W-50 or 15W-40 seem to be the agreed upon weights. Pick one that is most compatible with your operating environment. For example, if you run in Lake Mead (Nevada) where water temps approach 85 degrees (and air temps are near 110) in the Summer, I'd run the 20W-50. If you run in cooler bodies of water and use the boat in the Fall use the 15W-40. You can't go wrong with either. 3) Use a quality filter. Ford FL1-A is perfect and inexpensive. 4). Don't let the old oil sit in the pan over the winter. Too many contaminates in there. Don't over think this. It only oil The guys on the forum are only trying to help. If a half-dozen guys tell me "Here is what I do and why I do it" I'd probably do it (unless it involved pulling a tube). |
