But what mileage you guys recommend ??
To *really* know, you'd need to run some UOA's.
When you say "highway on the weekends", that should be sufficient to burn off any moisture that may have accumulated in the oil. When on the highway under ideal conditions, an OLM will barely move. When I drive 2 hours on the interstate, my OLM will only tick down 1, maybe 2%.
What is the OLM telling you? Why are you suspicious of it? It is suggesting something wacky like 2,500 mile or 12,000 mile changes?
well, I had use semi synthetic for 10,000 km and it was at 45% left, to me 10,000 km on a semi synthetic is too much, even on a full synthetic, maybe I would try M1 for that long.
And I know a mecanic a my local dealer, he said the dealer recommend 13,000 km on semi synthetic AC delco oil, before oil change.
Some car came back with worn cam shaft due to poor oil quality.
He usualy use that oil for his own vehicle, but for 6000km only, which make sense and give him peace of mind.
I would not take a chance risking my investment just to try stupid exaggerated OCI JUST to see how long it can last, I plan to keep my car at least 5-6 years.
My two cents...
