Looks hypnotizing to me. Id probably hit that.:****:
The small filter is only used on the trucks, not the SRT vehicles. Their excuse is that the big filter won't fit on the trucks due to the electronic power steering, which is BS. The small filter can starve the top portion of the engine of oil, which has poor lubrication to begin with. But hey, two things:
1) It's your motor, so you do what you want with it.
2) Cool if it works for you.
PUP is not top of the line oil, not even close. It doesn't even come close to Red Line Oil. The entire PUP lineup, including SRT 0W-40, are fuel economy oils. Look at their density, all of them are 0.841 g/cm3. Red Line 5W-30 is 0.875 g/cm3. AMSOIL SS oils are also above 0.850 g/cm3. Schaeffer's is another good example that's expensive to make. Synthetics that are that dense are expensive to manufacture. PUP is just a step bellow Mobil 1, which isn't saying much. I'll probably switch the HEMI to Red Line Oil next oil change. I kept putting it off because I still have plenty of M1 FS 0W-40, and I'm cheap. But Red Line Oil is good stuff, PUP is just meh.
The lawsuit is an Internet myth, and like many others, it's amplified with every post. Add to that the fact that in the end, things worked out well for everyone, as not they can sell us any soup made of various base oil, hydrocracked or otherwise somehow synthesized, and they can call it synthetic. Short of selling us refined crude as synthetic oil, they can use that label on pretty much anything. And guess what: no one cares anymore. If it performs, then all is well, and if it doesn't, then don't buy it.
I'm curious to know what makes PUP better than Mobil 1, other than anecdotal evidence.
@Burla @Hemi395 @Treburkulosis @tjfdesmo and everyone else reading this forum, I have a tiny riddle for you:
Why does Chrysler / RAM recommend 89 octane gas for the 5.7 HEMI when it's not even GDI engines? Its compression ratio doesn't warranty 89 octane gas either. So what's the catch?
I don't have an answer, but there is more to octane requirement than just static compression ratio. Limitations in combustion chamber design, swirl, and other factors come into play. I know, despite folks saying otherwise, my 6.4 ran just fine on 87.
I don't like RP produces either, of course RP filters don't have anything to do with RP except they sell them. Clones of amsoil filters, pretty good imo.
It is noticeable if you use 87 instead of 89. It ******* and makes less power when you use 87. I am sure it isn’t bad for it but I don’t like it. The same is true on my Yukon XL it calls for 91 and when I use anything less I can totally tell power is reduced. Idle is rougher. I use 91 almost always in that. I try to use ethanol free as well for better mileage.
PUP beats all other group 3 oils in analysis I have seen. Look at the wear numbers.
yeah times two
Funny walmart is selling pennzoil full synthetic for more then PP, I wonder if PUP changes it's name, I guess I should look it up as I type.
Others will not take on the Quaker State wear challenge........

That is pretty huge information imo. I wonder if they changed their formula to meet dexos or if it always did but they didnt cert it. Must find out.
If you look at pennzoil website, they say only PP and PUP is GtL.
