Default Royal Purple Replacement

Am going to replace transmission and rear diff oil with Royal Purple and wondering how much I would need to buy to take to Quick Lube and have them change it out. Thanks Marty

All I have to add to this is I would never take my car to a damned quick lube.

Find yourself a local performance shop and have them do it. Mine took about 3 bottles of the stuff, little over 3. Clutch feels super smooth now, but stick is still pretty notchy--in fact it feels tighter than before, but I have not had any slipping gears...

Doing mine tomorrow. Just picked up 4 quarts at Advanced Auto. $15.45 a quart was a shocker... You will use 3.7 quarts

Thanks for the replys, I forget that not all Corvettes come with a six speed manuel transmission"6M", only reason I mentioned Quick Lube was I do not have the right equipment to lift my C5, again thanks for all the quick replys. Marty

If you're going off the GM lubs be sure the new stuff meets the GM specs.

Quick lube won't change your Trans fluid in a C-5, at least not around the Augusta area.

I also used Royal Purple, with good results.
I also agree with the comment on the quick lubes, nobody will care more about the job than yourself.

Good luck.
