Don't do the local lube joint's 1-hr oil change.

A few years ago, I was changin' my E-250 [yeah Ford [:@]], and I had bought the metric thread instead of the standard thread. The oil was done drainin', and I had filled the filter to re-install. Wrong one! I put the plug back in, headed to the retailer, got back :45 later, installed the filter, and pulled the drain plug to see if any more juice would drain. I'm guessin' that I got 3/4 of another quart. That's the Campbell's oil too - the chunky stuff. THAT is the most important quart to get out when you do the O/C.

NEVER let the oil drain for less than an hour in your vette. 10-minute oil change? Not even in my V-1 powered, non-fuel injected, 1 speed, dual exhaust 22" pusherlawn mower.

And I didn't mention... I use the pre-change flush. It says it solves deposits. If it does, good. If it don't, no problem. The benefit, IMO, is that it decreases viscosity, and drains faster and better. Faster drain means more of the bottom jam will get carried off.

 

bumped up there...

 

I only do my own oil changes. I don't trust the idiots working there to jack the car up right and so on.
