Synthetic Oil

[Burla]

Yeah old chevy 350 does like **** thin oil, no old engine does.

I miss the SBC 350 days....

Nothing ticks like a HEMI 345

They will all work in the HEMI... The problem is the four-banger-sized oil filter. Granted, a thick 5w-30 / thin 0W-40 makes the HEMI run and sound better.

You seem to diss the smaller sized filters, what am I missing? I use top of the line oil PUP and Redline and run the smaller RP filter for 5000 miles.

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.

Thanks, I will go to the larger filter next oil change. Didn't know the smaller filter hindered the top end with oil.

I would say PUP is a step above Mobil 1, ever since the Exxon buyout and Castrol lawsuit.

But agree that Amsoil and RedLine are in the top class of performance oils. The main point is if one needs to reduce OCI for whatever reason, these oils are wasted money unless there is some specific engine design parameter they are needed for, our HEMI's being a prime example - a poorly-lubricated valvetrain needing supplemental additives to survive. Race application is another.

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.

Fun fact: sometimes trucks with the 5.7 HEMI ship from the factory with the big Mopar filters. Few people find out since many do their first oil change at the dealer.

Another fun fact: shaved cams and bad lifters happened in 2500 trucks with the 6.4 HEMI. Those trucks were all running 0W-40. However, they were also running the small oil filter. The thing about motor oil is that it will do its job. I've seen semi-trucks run a a million and a half miles on conventional oil. I've seen well-maintained cheap cars rack up 300K+ miles on regular 5W-20 or 10W-30 oil. As long as the oil carries industry-recognized approvals, it will work and do its job.

Many of us here are motor oil snobs and like to talk, bicker, and sometimes even argue about what's better and what's best. I don't think any of us are chemists or formulators. I am not. But you know what, it's fun, it's almost a hobby, and I get to meet many interesting and smart people in the process.

Back to your HEMI, the thermostat, grille shutters, and oil filter size will have a greater impact on the health of your engine than any expensive boutique or niche oil that you put in there.

That is what I thought prior to ram forum, I had never used redline before this, or anything except m1. However, ram forum had ticks on every oil you can think of and those ticks disappeared with redline. Not 1 truck, not ten trucks, closer to 100 trucks over 10 years. So my opinion has changed, there is no duplicating this work, 100 random forum guys, case is closed. 80% success rate from an oil change and fixing ticking engines, and to my knowledge non of those had a cam fail as of yet knock wood. The couple guys like Kap who had a fail with redline and a fail and codes before changing the oil. I think there was one other in the same camp. Now, what are the chances that 100 ticking hemi's and none had cam fail? Add that to long term falling wear numbers. This is welcome info for anyone with a hemi, unless they live at boobs the site of "unbiased" oil info, lol.

I don't disagree on Red Line, it's got PAO and POE, which cleans really well, and esters that have a bonded oxygen molecule to make the oil and additives cling to metals, and Moly that helps lube places where there is barely an oil film. But there is a bit more to it than just the oil, and that would be the bigger filter anf running the engine cooler.

I just let my truck tell me what to run, he's a finicky lil bch.

Same with some facebook ram groups im in. Atleast 3 posts a week about lifter tick. Ive told every one of those guys to try redline before doing cam and lifters and every single one except for one guy told me "oil cant fix part failure" which dont get me wrong is true if its to far gone. The one guy that tried it? His tick is gone.

Awesome, so you helped one deserving guy and a bunch of undeserving guys are still living in misery with the engine knock, lmao. Good work

No, but oil can clean and lube better. A lot of those ticking hemis are worked hard on it 5w20 oil. The hemi is running way too hot for off the shelf 5W-20.

So you guys have turned me around a bit, more investigating will be done, but I am warming up to the new Bronco. I didn't know they had this as an option with the 2 door. Now, this one sold for $1,075,000 as it was VIN number 1 (Barrett Jackson), but just maybe one of these might end up in my camp someday. I'm still feeling a 94-96 resto, but I will at least sit one of these before chosing.

 

[tjfdesmo]

392 Rubicon. Eff a Bronco

 

[Burla]

I traded a Heep for my current ram, never again. When it's time I will see if I say yeah or nay on the newer bronco versus the older bronco, but there is nothing like those 351w bronco's, just love'm.

Its also spec'ed for NON synthetic 5w20 with some rated to tow up to 10000lbs. Talk about over working dino 5w20...

Yes but i will never stop! Lol must save the ticking hemis!
