Someone just posted the Pep Boys ad and one of there deals is 5 quarts of Royal Purple AND a Royal Purple filter for $39.99, no doubt a great deal for Royal Purple. The question is, is this oil really worth it? I am currently running TGMO 0w20 and a Fram Ultra in the Accord, I like the combo. I wouldnt mind trying something different though. Anybody used Royal Purple, specifically in the 0w20 or 5w20 weights? Also, has anybody used the Royal Purple filters and had issues with those? Thanks! If it really is as great as some make it seem, I wouldnt mind paying a couple extra dollars and giving it a shot.
