What about Summer weather? Over here our temperatures are like +50.C with humidity to match.
There are over 300 polyol esters used in motor oil formulations specifically for internal combustion engines, and none of them is the type used to manufacture jet engine oil. Polyolester fluids have greater film strengths, greater fluidity, spread better, coat better, stick better, and resist high-temperature oxidation better than PAO's or mineral oils. Esters are part of full synthetic oil formulations because they increase additive compatibility, enhance seal swell, increase the VI, and resist high-temperature oxidation. It depends on the formulation and the motor oil that is being manufactured, and the performance targets that the manufacturer sets for said lubricant. RedLine has good marketing, and makes a decent product, however, their oils today are majority PAO, not majority Ester. Should the consumer be concerned with individual components that go into an oil formulation? Absolutely not! The final performance and value for money are all that matter.Anyway, Red Line has the highest oxidation resistance of any motor oil because part of it's base oil stock is polyol ester (POE), which is jet engine oil.
I'm not sure why you think I think you're my enemy, you are way too sensitive to be on this forum if you start thinking like that. You're posting stuff I don't agree with, I post a response.
I've also publicly (in this thread) disagreed several times with other posters on whether idling is bad and causes hemi tick, my opinion is that idling does not cause tick, nor is there some flaw in the design with poor oiling (lifter oiling is pressurized, it doesn't need splash oil); I believe it's dirty oil, and/or bad lifter manufacturing on specific lifters. I've also disagreed with the amount of tick cases, I think it's below 1% and others are saying 10%. Point is, none of this is personal, it's just my opinion.
Getting back to the discussion: you said there is no reason to run 0w-30 in winter instead of 5w-30, and you based that on viscosity. I'm saying that is not enough (single metric) to come to a conclusion on what oil is best for (even light) winter usage... as in my experience, there is a difference in engine noise between the two, even above freezing.
I don't know why/when/what is causing the difference, nor do I care to be honest. The difference is there, that's all that matters.
Are you running the stock thermostat?@FalconHemi Thanks for the info. I have used Motul 300V in the HEMI and honestly, the engine sounded a bit noisier than usual, but there was no ticking or anything. At the time, I was trying to get Redline and it wasn't available. So I was wondering what should I get. @Burla suggested Motul because the formula seemed similar to Redline. If Redline wasn't going to be available by the time I needed to change the oil again, then I was going to give Amsoil 5W30 a try.
As stated before, I would prefer to stick with Redline since it has been well documented.
I know that people in Australia love their 0W-40 oils.. I believe Penrite and Caltex are the favored brands over there. I don't know about Ram owners and would love to know what they use since they are quite hard on their vehicles over there with regular outings into the Bush.
It was a theory about Motul, there is not really a substitution for redline 5w30. If you get a chance, buy as much as you can. At any given time I have 3 plus cases in my garage, and I even have more royal purple filters to match it. It is hemi honey, anything else has just not proven to be. you should know brother.@FalconHemi Thanks for the info.

I like to try out new stuff, as long as it's safe. It sounds like you got well-built engines in those sweet rides. Unless you have a passion for lubes like I do, stick with what works for you.I run 0W40 PUP with and XP filter in my 6.4L. I ran 0W40 PUP in Viper with the SRT filter. I ran 0W40 Castrol Edge European and OEM Filter in the Porsche Cayenne S. The Porsche and truck have/had 5K OCI's with the Viper getting changed yearly (typically 1 to 2K miles). Should I go to Redline 5W40 living in Michigan? I have no Hemi tick and I'm at 180 & 1200 idle to run hours on the EVIC. I'm happy with PUP and the Engineer's I dealt with when I was working agreed with no other recommendations unless I was tracking the Viper heavily then 15W50 Mobil 1 would be advised. I have 1 more OCI until I run out of my stash of PUP. 62K on the truck FYI.
@Burla Haha.. Thanks for the advise. We need that honey. I plan on being the guy that takes his HEMI engine to a million miles (if I can).It was a theory about Motul, there is not really a substitution for redline 5w30.

Sorry but im gonna be the guy with a million mile hemi! Lol in all seriousness redline should work really well for you!@Burla Haha.. Thanks for the advise. We need that honey. I plan on being the guy that takes his HEMI engine to a million miles (if I can).
I understood that Motul was just a theory. I don't know about the long term effects of using Motul 300V since I only used it once.
It was more pricier than Redline and the engine was a bit noisier, but still quite smooth. I decided that next time I would try Amsoil 5W30 or 5W40 if there was no Redline.
The only AMSOIL lubes fit for your climate are the ones below. They all have an HTHS of 3.5 or above, provide good MOFT, carry European OEM approvals, and are loaded with high-quality additive packages.I decided that next time I would try Amsoil 5W30 or 5W40 if there was no Redline.
How often do you service your transmission?I plan on being the guy that takes his HEMI engine to a million miles (if I can).
It's not a good idea to test out other people's theories on your engine. Especially by putting racing oil in your engine.I understood that Motul was just a theory.
Racing oil is formulated to provide maximum wear protection for the duration of a race, multiple track sessions, etc. There aren't prescribed OCIs for racing oils because racing teams usually tear down their engines, and based on measurements and observations of the engine internals, they decide how long to run a racing oil.I don't know about the long term effects of using Motul 300V since I only used it once.
I am unsure whether the noise is piston slap or in the valve train, I have heard various explanations.
Customers have experienced a reduction using our oils, regarding the difference between our 0W30 and 5W30, the 0W30 would be a little lower viscosity at low start up temperatures, possibly getting up to the valve train quicker. The HTHS/film strength is about 10% higher with the 5W30. The 5W20 though would be a lower viscosity at lower temperatures.
Response from Dave @ Redline:
Nothing really conclusive there unfortunately.
I'm still glad he responded. I have probably around thirty email exchanges with him, and while not always satisfying my neverending curiosity, it's more than I got from any other lubricant manufacturer.Nothing really conclusive there unfortunately.
That is sweet man, where did you find that? Young engine and probably mirrors the best ever uoa on the board for a hemi, I envy that hemi, lol. 5w20 isnt a bad move for hemi's at all, as long as it aint ticking.
Yaaaasss.
That's the original recipe with high calcium low magnesium.
Copper is tad high, so was mine. Iron wear is moderate and fine.
Note TBN is fine. Like I've said, it really only measures how much antioxidation additives remain.
The oil itself can go longer, but Hemis being so sensitive to contaminants and filters we been changing @ 5,000 miles. Even with Red Line.
Still relatively cheap insurance for an expensive engine.
Caught my eye on bitog. Tbn made me almost think it was your 2 year uoa but wear is nice hereThat is sweet man, where did you find that?
