Switching to RP?

[TurboT-bird]

only problem Ive had with fram was no backflow valve in the filter they made for my 2.3 turbo and the stock filter mount had it laying on its side and all the oil drained from it when there was no pressure so every start was a dry start. Ive run them on other motors and had no problems.

I'll be totally honest, the only filter I have EVER had a problem with is one of them Deuche (spelling) filters from Autozone...

I have put RP in both my Ram and my Grand Cherokee. I found that the RP really quieted down my "Hemi Tick" a good bit more than than the Mobil 1 I was running.

The GC also responded quite well to it, picking up a solid 1.5 mpgs after the change (well until I lifted it and put larger, more aggressive tires on it).

Currently running Valvoline full synthetic because the auto parts store had a killer sale on it when it was change time.

I almost always run a Wix filter, but have used Purolator Pure 1 and Mobil 1 filters. Those three along with the K&N always get top reviews.

Fram ALWAYS is the worst filter tested in every review I've ever read.

I'm not really brand specific on my oil, I'll stick with a name brand, full synthetic every time though. I'll change my oil and filter every 6k miles or every 6 months, whichever comes first. It's usually 6 months on the truck as I only average about 8k miles a year.
