The first and mandatory step in showing that your oil is better than a different ACEA C3 oil would be to show that your oil fully meets ACEA C3 too. Otherwise we're in the "one armed bandit" territory where one could show that shampoo is better than oil.

I keep hearing that all those cars populating the junk yards have perfectly working engines, up to factory specs, and that the reason for which they are there is obsolescence or rust. Is there any evidence to support this theory?

Actually I was first intrigued that there was no 0W30 or 0W40 mentioned... but then I figured it out that probably they saw no value in running 0W downunder, other than to maximize "fuel economy", at which point you would be looking at the 0W16 - 0W20 variants anyway.

15W40 yay! Good finding, Shannow!

Speaking about "fuel economy"... I always wondered... A teacher teaches, a painter paints, a driver drives, but what is it that an ecologist does? What's the verb for it?

Originally Posted by demarpaint I answered the question, in insane cold the 0W20 would have the edge. Me I'd use a 5W30. but that wasn't a choice. There's also Mobil 1 0W30 AFE that's pretty close to the xW20s and could be used in "insane" cold....

Originally Posted by ZeeOSix Lots of miles (km) on those oil runs - and the wear deviation starts showing up after 10 km. Did they take KV100 and HTHS readings as the miles piled up to see if the 10W-40 sheared down below the 5W-30? Lead wear would be journal bearings I would assume. The...

Here's a different one https://www.sciencedirect.com/science/article/pii/S0301679X15003709 that may have the effect of rejoicing the thin camp. The thicker oil produced less iron but sensibly more lead in the UOA.

My chauffeur told me that Lincoln dealer service ain't bad either. They use 5W30 though.

That pic looks like the perfect poster for extended OCI... err brush interval....
