I am going to be switching over to Royal Purple for use in my drives. Where is the best place to purchase a case? Thank you.

NAPA carries it. Might ask them if they would cut you a slight break on price with the purchase of a case.

Also NAPA, best to order it in a 5 gal pail

Thats what Konrad uses!!!

There's only one!!

Royal purple is better then Amsoil????

I had so many recommendations to go with Royal Purple. Guess I'll be visiting my local NAPA store. Thanks.

Do I want 75w90 Royal Purple? I see that there are other choices. Thanks.

What drive r u using it in?

I have tried both 75/90 and 80/140 rp,the thicker stuff offers more protection on big hp thru bravos but will cost you a mph or 2 in top speed,Smitty

Go online to www.royalpurple.com and through your zip code can find who is handling it close to you. I took over Tres Martin's distributorship of it when he moved to Ocala. I can't keep enough in stock!

I use it in everything. (if my wife's vibrator used oil, I'd put it in there too!)
