I’m doing a little marketing research here. I’m wondering what the most popular oil viscosities are. If you’d care to share what your favorite brand is, that would be helpful too. ---

> [@squid](#): > > Remember about how much you paid for either the Royal Purple or Redline? Too much, I believe it was like $8.75 a qt from Summit, although I used it for 6,000 miles though which is pretty decent. EDIT: For anyone that is oil ignorant yes you can use certain oil’s like Redline and German castrol for much longer change intervals. ---

Did anyone read the writeups all over the net about royal purple. Supposidly its over priced garbage, thats actuially worse then common syn oils.
