Oil change

[maupineda]

When I was trouble shooting vanos pressure issues I made several pressure tests with 0w40 and 15w50 and there was no change at all between idle and 3k rpm

I actually do not run 10w60 at all, I have used either 0w40 or 15w50 mobil1. the car runs the same with both, and 0w40 actually runs cooler in normal use as there is less energy to displace the oil through passages and galleys. If you abuse it for long periods, on a hot day, at an incline, with AC, I have seen the needle move passed just a touch right to the middle, or 220F - 105C depending on where you live, that said, it also comes back down instantly to right of the middle point to 95C. I also use ceratec with every change. we will see how my bearings come out next year when I can do them; my car has 87k kms. I would only use 10w60 if I pounded on it all day, every day.

I used 0w-40 during Milwaukee winters. But I don't think I'd ever use 0w-40 at the track again. Especially when it's hot out.

Agree, in my case I dont abuse the car, just the occasional redline pull here and there, but mostly cruising, so in my use case, is fine. fun fact, my car has averaged 9.8l/100 or 24 mpg for the last 14,000km.

I would if I were going to track the car. I haven't compared their signature oil to the Euro 10w60. When I initially made the choice, it was because the 5w50 was almost comparable to Shell's and Castrol's 10w60, but it performed better in shear tests. Project Farm conducted tests and demonstrated its superiority. I'll have to find the guy who conducts parts wear tests using different oils on YouTube; he maintains an extensive Excel database with almost all the available oils.

I know that's a lengthy explanation for saying 'no,' but I thought it would be best to provide a bit more context.

Ramo, ugaexploder both. In Piotr's channel, there's a Google Excel sheet containing all his tests. I appreciate Project Farm for offering a different perspective and providing valuable insights. I've been attempting to persuade him to conduct a test on all 10w60 oils and have even considered funding it. This would help put an end to the debate and provide solid data to determine which one is superior.

Project farms oil tests are a waste of time. Do not use them as a guide for anything

Can you expand on your thinking here?

Scores are based on test measures that are not the most important to be considered

Two of the tests are viscosity tests. The viscosity is written on the bottle so for the same grade they will fall within a tolerance. If you want a thinner oil then use one.

the lubricity test (wear scar) doesn’t replicate what’s going on in an engine it’s like a one armed bandit test not important for what we are dealing with.

no dude in his shed is going to come close to properly testing oils
