Not silly.
But I do my own oil changes. It gives me a chance to look underneath the car, and look at what I can’t normally see. We all look at the topside of our cars, some more closely than others-but a lot of us ignore the underneath.
Much more serious stuff under there than paint.
On past cars, I’ve caught loose bolts, missing bolts, road damage, minor fluid leaks, etc. All undetectable from above. And if everything’s good to go, at least I can see where technology has gotten us. A set of Race Ramps and some initiative will just about do it-these forums are loaded with helpful info and people.
