2010 Chevy Equinox, 3.0 six (DI), 16000KM on FF

[rcy]

Normally I post the actual pdf, but I'm at work and don't have the necessary tools..so I'm entering the figures manually.

Oil was factory fill, 16000km, oil change indicated by GM OLM. Vehicle was first in service the third week of December and the oil was changed in May IIRC. Mostly highway miles, wife has a heavy foot, and I favour rapid acceleration.

For 7% fuel dilution

I think I was expecting the oil viscosity at 100C to be even lower than the 7.7.

As was asked earlier, did you add much/any oil in this time frame?

The wear numbers are a lot better than I expected them to look, especially when I saw the 7% fuel dilution number first before I scrolled down to see the wear numbers.

No make up oil, I think the sump is 5.7 litres IIRC (at work, and car is at dealership getting a CEL dealt with so I can't check the owner's manual).

TBN still showed life in the oil. If this wasn't a factory fill with all the wear metals, and if not for the fuel dilution, would you say the OLM is accurate?

Any idea what PQ stands for in the wear section?

That is a bit odd as the larger GM 3.6L DI engine found in the Lambda has a sump of 5.2 litres.

Particle Quantifier?

Province of Quebec? They need their numbers in French?

Just checked the owner's manual on line at gm.ca and it is 5.7 litres for the 3.0

Do you have sump envy now?

Poop Queen....




Particle Quantifier is correct

I'm surprised that the TBN was still so high.

. My thoughts exactly!

Rouge, I have to agree seems odd but my 2.4 ecotec takes 4.7L and the wifes 3.5 only takes 3.8L. Would be interesting to know the logic behind it.
