Nw Iowa | I love synthetic oil. Started using it in a Pontiac bonneville at 20000 miles, changed oil every 10000, has 250000 on it now, longer drives, but drove hard,still doesn't use any oil. It was kind of a experiment , don't recommend it as I like to change oil before mfg recommendations. I think now most cars mfg recommend some type or mix of synthetic. We always change tractors and combines at 150 hrs. Leased a new cat tractor and their service dept said first change should be at 450 hrs. We went to around 250 as book said and changed it because I didn't want to be liable for a engine failure. It was one thing to experiment with a car ,quite another on a semi or tractor.
I remember a serviceman from a local dealer telling me that a customer would always trade cars around 20000 miles with org mfg paint on filter, how would you like to buy that low mile used car? | |
