I agree inhaliburton, an engine tear down/'mike' up will reveal everything!
However,most engines-good or bad, don't get torn down unless there is a desire to fix vs trade in the car.
In my case,both now, and in the past with the older cars,the engines all ran like a tops. A tear down just for fun would be crazy,unless one is in the racing circuit!
There would also be tell-tale signs if an engine is getting worn,such as-burning oil,power loss,fuel economy drop,noise,smoke,etc. If none of those issues ever arise,life is good,and so is the oil!
I should also mention that cutting open the oil filters for inspection is very telling as well.
Using those filter mags isn't a bad idea either,especially during oil filter inspections-whether using Synlube oil,or another lubricant.
Well guy's... have a great weekend!
