lol I didnt even think about royal purple when I made the poll my apologies... I heard of royal purple but never had any experience with it.... Started using Mobil1 a long time ago on my Jetta and in my friend's LT-1 Z28 and there was a NOTICEABLE difference in driving feel (less vibration from the engine). I now am starting to wonder how well royal purple is lol...

mobile, i was using royal purple but after reading a bunch of reports i i switched to mobile 1! just got better scientific/user reviews

I would never put Royal Purple in any motor.

I use Mobil1 but and I'm gonna try Castrol SythBlend next change.

please explain....

 

[Earful]

Used Royal purple in my Acura powered Civic...it was very smooth. I would like to Redline...currently using Mobil1.

 

[Maxx Mazda]

Mobil1 and K&N HP-1004 best combo aside from Mobil1 Filter... That would make it ultimate.

 

[k-lea]

please explain....

search on oil's there is a BIG discussion on it.

*actually, you might just want to save yourself the time. i couldn't find the specific thread i was looking for so i'm sure you wouldn't be able to either.*
