Hi, I use full synthetic supertech oil and Fram ultra oil filter ( most top of the line filter), last week computer started showing 15% oil life, but looking at dip stick. It looks fine... any advice
A visual look at the oil has little bearing on its chemical ability to protect the engine. Also, the oil life is a calculation by the PCM, not some measurement of actual oil quality.last week computer started showing 15% oil life, but looking at dip stick. It looks fine... any advice
Except you miss the codes for other service required. This advice just wastes oil. Ignore your grandpappy's advise and use the maintenance minder. Religion has nothing to do with it, although I do have faith in changing the transmission fluid every other oil change.When in doubt, I am religious about changing my oil every 5k miles or 5 months regardless of what the MIL says. Call me old school, but $40 for a 5qt jug and a OEM filter and 20 minutes in my driveway for a fresh change is cheap insurance.
