Has anyone ever got negative results on an oil sample? I never have...there's a remark that says everything is normal on every one I've ever done.
I know the reason some of us do it, don't need that lesson, but do you REALLY need to spend the $17/oil change? Of course they are a good idea, but every oil change is it necessary? Every 2 or 3 changes perhaps is what I'm thinking.
