Jim, you're a great resource on the NG, and your customers are lucky to have you, but...

I change my own oil. I don't give a rat's ass about saving money, I do it because I don't trust the barely trained monkeys that actually perform the oil changes at the shops around here. There are no master mechanics doing oil changes... they are barely out of high school, waiting for a factory job to open up. They wouldn't know a leaking tranny seal if it bit them in the butt. Chunks of pistons and bearings could fall out of the oil drain hole, and they wouldn't give it a second thought. That's reality on the planet I and most of us live, so don't be so hard on us, eh?

I have to agree. How are you supposed to know if you are developing a leak if there's no dipstick.
