Interesting Oil Change View
I live in a temperate climate, not too hot or cold...--
I have a fundamental view.. the reason engine lubricant turns black, is contamination from combustion, mainly carbon, amongst other things..
Carbon is very abrasive,, and I don't care what lube you're running,, the longer carbon is in contact with wear surfaces, the more wear, (specially with the newer tolerances).. sure I CAN leave that abrasive in my engine,, but I prefer not...
so if I'm changing oil every 2500 miles anyway,, why pay for synthetic
Now, - were I to live in sub zero temps, ( God bless you folks)
- I would want to run synthetics so the lube doesn't turn to goo,, but I bet I would still change lube every 2500 miles anyway..
good habits die hard... lol
