Yeah, they are a beastly filter. When you got 7 qts of oil needing a cleaning though, don't want to skimp out on the cleaner. lol
Oh god.... Not the oils question....
I've ran RP since the first oil change and love it. After reading a few post on oil, I'm going to try Amsoil in my next oil change.


Original Import Sized Filter?
:****sweak:
I crushed that little ******* removing the first (and last) one from my truck.
Spun on a nice full size fat one the last three changes and have had no issues.
FYI, that little **** filter would spin right on the 360, same dia O ring, same thread pitch if you were so inclined.
Mobil1 here - have used RP and Amsoil too on the 1500 for extended change intervals. I've been doing every-other time the oil meter recommends. So, basically 8200 miles avg. per oil & filter change for me on the Power Wagon.
Was doing 7500 mi Oil Changes on my '03 Mustang Cobra with the S/C'd 32v motor. When I smoked a couple of pistons doing back to back top speed runs on a dry lake. Pulled the motor, and even with high boost and insane IAT and chamber temps, with 43k on it, it was spotless. I now do 10k changes on it, unless it is out for a two day roadrace weekend or something.
People are just throwing away good fluids way too early 99% of the time to feel good or feel like they are taking extra care of their vehicle. It's not emotional, and it doesn't care. The days of cooked on, sludged up pans are pretty much gone, with such efficient systems now a days and the use of Syn. Oils and good filters. I could probably triple my intervals, but am too old skool a bit myself. Though I know I am throwing money away.
