Oil changes with synthetic

That CR test with taxis doesn't have one critical cycle of us folks who are not taxis drivers

NY taxis are almost never shut off for more than the time to refuel. In some of those CR reports, there were some who didn't turn off to refuel.

Us non-taxis drivers shut off our engines over might.

That then has moisture drop out vapor to condense inside the engine


Plus the oil film flows off surfaces

To have parts go metal to metal on startup

The why synthetics with better film strength will take longer to flow off

The quality of the filters anti-Drain valve determines how much oil stays in the oil galleries. That helps prevent metal on metal starts

Why more and more oil OEM's are adding molybdenum, which plates metal surfaces

Moly on moly has a VERY low coefficient of friction

Arguable, but many articles report 40%-50%-60% of all wear of an engine

I'm of the opinion of changing engine oil regularly and before the manuals recommendation

Thank you for your opinion on this, BenK.

My new 2022 Silverado cost a huge pile of money and I want this gasoline turbo to last for the next 10 plus years. I don’t want to trade or buy another truck.

This little gem will get fresh oil in the crank case often, coolant changes at 30-50k miles( not sure which yet) due to the variable cooling system (the heads and block can be cooled independently via electronically controlled ball valves.) The transmission fluid will be changed at 50% of the recommended interval, and the other fluids will be changed at 50% recommended intervals.

I need this expensive and impressive (to me) machine to last 10 plus years.

I’ve seen sludge in engines and want to do everything possible to prevent that from happening to my machines.

JMHO.

Thanks!
