OCI with German Castrol 0W30........Check In!

[jsharp]

I did one run of about 7500 miles and another of almost 10K miles. The stuff works just fine for long drains.

10K OCI; same as with M1 0w40. Audi allroad 2.7t.

The oil you use has nothing to do with when the oil light will come on. Nothing in the oil is measured by the computer. This is calculated based on engine parameters measured by the many sensors on it. None of the sensors meausure oil viscosity or TBN.

Yes, I know this. I was simply saying that with my driving style/routine, my OLM allows me to go longer on OCI's. If my OLM didn't come on until 7 or 8K miles on a regular basis, then I know I can run a good syn for that interval. I know it has no way of knowing what type of oil is in there, or what the TBN is. I'm just saying there's no way I'd run a dino for 7-8K. Now if it kept coming on at 3-4K, I'd probably run a dino....

Hi,
from Jan 1997 I had these OCIs (over 8 oil changes) in three different engine families;

Average = 18kkms (11k miles)
High = 24kkms (14.9k miles)
Low = 9.3kkms (9.3k miles)

blsnelling - you said this;
"The oil you use has nothing to do with when the oil light will come on. Nothing in the oil is measured by the computer. This is calculated based on engine parameters measured by the many sensors on it. None of the sensors meausure oil viscosity or TBN."

This is only partly correct - the latest oil sensing devices used on some vehicles do in fact measure both viscosity and (effectively) TBN
and some are oil composition sensitive! The pages are still being writ..................
