Oil Analysis Report - Castrol EDGE 0W-40

[Entropy]

As I'm approaching 100k miles, I was curious how things were looking inside my engine. I ordered an oil analysis report for my last oil change, which was a 5,000 mile run of Castrol EDGE 0W-40.

This is my daily driver and is driven 90% city (short trips) and 10% highway. The oil appears to be unphased and could certainly go longer than 5,000 miles. Overall, I'm satisfied considering this is the cheapest readily available LL-01 approved oil out there. I'd go as far to say it's the best "euro" (LL-01, A40, 229.5) oil available.

Good to know, and thanks for posting your results! I was going to use LiquiMoli since that's what I use in my E36 but a member here (maybe you) recommended Castrol Edge. Good to know it looks good after 5k.

I use Lubro/LiquiMoli for almost all my cars. Whats wrong with Lubro?

Nothing wrong with it. Just not as good Castrol IMO, and certainly not worth the premium. LM is Group 3 base oil while EDGE 0w-40 is Group 4 PAO.

Thanks. Good to know

You added 2.5 qts in 5,000 miles?
So does the oil test good because you keep replenishing the additives?

Yeah I lose about a quart every 2,000 miles through the valve stem seals. Certainly adding oil makes the test look a bit better. But regardless, the wear-metals are very low which is nice to see.

'08 4.8i with 145k. Adding a quart every 4-5k. Guess I should consider myself lucky.
