Spork -"If saving 30-50 bucks a year on oil is making or breaking your budget, high performance cars may not be for you." Did trying to demean me make you feel better?
There is very little difference in 0W, 5W, and 10W in performance, and Mobil 1 is available near me while Amsoil 10W-40 is not. It's not the $10-20 difference in price that counts. Other than pontificating about various "points" of Kinematic Viscosities and VI, can you give any objective evidence of lower pressures at cam journals and bearings, how you measure that, and the damage that is happening to the engine because of that? And your engine oil gauge is what, useless? Also, the viscosity designator on the bottle can be misleading? Then how do you buy any oil then if you can't rely on the manufacturer's designation? And you are wrong about the cold winter temps down here, I don't know where you get your info from - it is very often in the 30s and frequently in the high 20s here in the winter. This discussion is becoming the same as what tire pressure you run, that which is on the door sticker, or 1-2 lbs. higher or lower than what is written there to suit your driving preference. |

No modern engine needs 0w oil to start in cold weather regardless of temperature. It's used to decrease emissions in the time it takes the engine to reach operating temperature. The claim that it "reaches critical components faster" is more marketing bullsh*t to make you feel good than anything. I'm sure the entire of the automotive industry experts and all the design engineers I work with in a company that has designed and built flat tappet air cooled aviation engines for 93 years are wrong and you have it figured out. |

I don't want to belabor this, but I have to respond to you -
Is it OK that MH recommends Amsoil 10W-40 because of the ZDDP levels while that is different than GM saying Mobil1 5W-30 is what's needed? Does he know more than the engineers who designed this motor, or is that his personal opinion? Why does he say a "heavier" weight oil with higher levels of Zinc and Phosphorous is so much better than what the factory specifies? If it was so beneficially great, then why wouldn't the factory switch to this recommendation too? All the 0W-40 designation means is that that oil is suited to a wider variety of temp extremes than a 10W-30, and not that it matters, but where I live it varies between 30 and 100 at different times of the year and any engine oil on here will also function adequately in those extremes. You are skirting around the questions I asked you and are avoiding the issue because you cannot answer me. And you also cannot show me any evidence of higher wear or damage to any part of the engine from using any of these oils. I expect next you'll say that compression testing is only an "estimate" of what's happening inside the cylinders. And explain how a lower weight oil (0W) decreases emissions until the engine warms up. Then tell me where I said anything close to "The claim that it "reaches critical components faster" is more marketing bullsh*t to make you feel good than anything." Then you said "I'm sure the entire of the automotive industry experts and all the design engineers I work with in a company that has designed and built flat tappet air cooled aviation engines for 93 years are wrong and you have it figured out. " No, I have not figured it out, but maybe MH or the other gurus who work on these cars have, and YOU are wrong. Oh no, that's inconceivable. Air cooled aviation engines and liquid cooled automotive engines are the same thing, same requirements? That's news. And you do realize that things do change over the years, right, that advances are made? What was originally recommended 32 years ago may not be as good as what's available now? So I'm done here now, have at it, and if you're going to make another pronouncement, back it up with some real objective evidence. We all want to learn on here. The oil you use is just as much a personal preference as the tire pressure you want, as I said. All the modern oils perform pretty much the same and if you change them on schedule, you'll be just fine no matter your choice. ![]() Last edited by mlipmd; 05-10-2022 at 12:03 PM. |

Show me where I said 0W-40 is offering any level of protection beyond a 10W-30. I never said that or implied that. I use that oil for the higher levels of ZDDP, get it? And that's what I said.
0W is not the best choice for minimizing wear? Tell us all what is the best choice, in your mind, in your opinion, as the "expert" on here. You still did not answer any of my questions and go out of your way to avoid them. Show me evidence of any detriment to using Mobil1 0W-40 (which I use for the higher ZDDP levels only) over anything else mentioned on here. You can't. Even something simple like tiny metallic flakes on a magnetic oil drain plug, metal in the filter element, lower compression ratios, higher amounts of metal in an oil analysis, valve ticking or wear. You can't. And show me one study proving your claim that 0W wt. oil decreases emissions and gives better fuel while the oil warms up. If that were truly the case, then by now the govt. would insist on all vehicles use that. You call me a layman, do you have any idea who I am or what I do/did, what research I have done on oils, who else I have read and gotten valid opinions from? If you really do deal with these things, in what capacity, and why can't you back up your claims with any facts. Nothing personal, just the facts. |
