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

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.

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. |

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. |

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! |

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 |

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/ |

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 |

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.................... |

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 |

So, just to make sure I'm understanding you, you're saying the brand of oil is more important to you than using the manufactured recommended weight? Not trying to be smart,,,really want to understand why you guys use what you do. |

oil is such a hot topic, you should visit a Harley Owners site some time. people about kill each over this topic.
Im guessing those running 20/50 are using synthetic which flows much better than conventional oil, likely the reason for the heavier weight over the 40. These engines work hard, much harder than car engine. I would guess that 15/40 Rotella or 20/50 pure synthetic would be the best oils to use. EPA controls the additives in oils. I'm guessing that oil branded as Racing likely circumvents EPA as does Diesel oil. Anyone know of any facts around this? |

Because Valvoline doesn't make a multi viscosity VR1 40 weight

So why do you guys choose a 50 weight oil when 40 was the original recommendation? Is that based on anything objective, or just preference?

For more information than you could ever possibly digest, try:
Bob Is The Oil Guy website. Lots of good info there, but you need to sift through some background noise. JQ |

I don't know the specific ZDDP additive level. Based on Royal Purple statements, the oil does contain zinc and phosphorus. To quote from the Royal Purple website: "Royal Purple HPS Series motor oil is specifically formulated to maximize performance and meet the demands of high performance and modified engines. HPS is recommended for vehicles no longer under manufacturer warranty and for those seeking a higher level of performance and protection. This unique blend enables HPS to outperform leading synthetics and conventional lubricants for both gasoline and diesel engines. Royal Purple’s HPS is fortified with a high level of zinc/phosphorus anti-wear additive and Royal Purple’s proprietary Synerlec® additive technology." I like the Royal Purple stuff. I've also used Mobil 1 Racing in 15W-50. |

Neither Ford who actually built the engines nor PCM who is mearly an engine conversion company has tested or have had one of these engines in their hands for something like 15 years. When they did oils were designed for flat tappet engines.. Since these engines were discontinued,the oil specs have changed. Why would they have kept up with oil technology for an out of warrantee past product? They do not even support them for parts,they are in the business of making a profit selling new engines. But take their word as gospel over multiple people who have current experience using current oils in older engines would IMHO false security. I would not call Ford to ask what to use in a model A anymore than I'd call at&t and ask what the best rotary phone is. |

So weight doesn't matter??? I've seen a lot of different personal opinions on different weight oils. That's why I went back to PCM since I didn't see much/any available in 40w40. |

Rob, Doesn't the work "street" indicate there isn't ZDDP added? Is there any and do you know at what levels? |

Glen,
The brand comes down to your choice but the key is to make sure it has the proper levels of ZDDP. I've been running Valvolene racing 20-50 in all my boats for years. |

Most automotice OEM's specify an oil weight and give a brand recomendation...
So whats wrong with calling PCM and follwing their recommendation? Byt the way, I followed Zach's recommendation which was also Rotella... |

I use Royal Purple HPS™ – High Performance Street Synthetic Oil in 20W-50 for the engine. I also use the K&N oil filter (number 3001).
The topic of ATF will likely get a little debate. Friction modifiers, synthetic vs. non-synthetic, etc. Lots of folks here use Valvoline Dex/Merc ATF. JQ |
