time for an oil change
You should since it increases longevity just like changing engine oil does for the engine.
The service engine soon is the same as a check engine light. It has nothing to do with an oil change.
never it should out last the engine
Need to know what year and engine.
You have to take the engine out, unfortunately.
well I'm changing a fuel filter on a 96 st blazer and just making sure i put it on right the side that says out it that towards the engine or is towards the back?
When it go's out and the engine quits are when you can no longer set the timing with an engine scanner.
When you overhaul the engine. It is designed to last the life of the engine.
There is no point in changing it.
4 and 1/2 qts with filter change.
The only way is to have the engine control module reprogrammed.
