Thank you- I did some more searching and that is similar to what I read elsewhere....is there any reason to be concerned about not completely draining the oil, since the car is still on the ramps when you tighten the bolt back up?
I've always used jack stands on my 300zx, and lowered the car to drain the oil completely, then jacked it back up to put in the drain plug. What are your thoughts folks?
And thanks for the help. Paid the shop to do the first oil change, as a way to let me get under the lift and take a look at the under carriage. From here on out, I plan to do it myself.
