Synthetic Oil

[U&A]

Usually all 0W40’s shear down to a heavy 30w after a good 1000 miles or less

Quoting my own post

My favorite oil for my 6.4 is actually Redline 5W30. All year round

interesting uoa, this guy went from thin oil with high moly to thick oil with 1/3 the moly and the iron level tore the roof off. ow40 fs did shear to 5w30 and the wear was horrible. Now, FE was raising everytime which would concern me, and it is only one single uoa so hard to draw any conclusion, but for whatever reason this hemi did not like the m1 fs 0w40. I still have confidence in this oil, but if I seen a couple more of these I'd say look elsewhere, like the 0w40 amsoil ss.

And amulinum shot up which you can expect with a 0w40, simple thick oil leaves those cold pistons exposed at start up even 0w40, but the iron is a wow thing. Could just be an engine failing moment dunno.

I ran 20W50 synthetic in my 2006 SRT8 300C.

She was my summer only vehicle (stored winters) and this year engine had the common 6.1 oil squirter whine when at full operating temps. Sounded like a mini supercharger at times...lol

After I switched to this viscosity oil there was not a peep out of her, even after repeated 1/4 mile runs at the track in the summer heat.

Although, I had to ensure I was at full operating temps before I drove her spiritedly as that was some thick A Z Z oil!!!!!!!!

My fav seasoning is Apple wood smoked flake sea salt & black pepper, let it set 20-25 minutes then the meat goes on a hot BBQ (charcoal briquette not a gas grill or pellet) along with a good amount of the Kingsford blend wood chips ( apple hickory oak) mmmmmm, but if I want to change it up will use Montreal seasoning or add a mix of Johnny's & Lowery seasoning....

Personally

I would not want to run 0W 40 mobile in a hemi unless I have a really happy hemi that produces low wear numbers. M1 uses primarily GTL base stock and im not fond of them in terms of shear strength.

No, I have been out of the game with this synthetic oil stuff for a couple years now so things may have changed

yeah it changed a bit, in the msds it shows that m1 to have a high percent of pao, that is why you see uoa's with pup 0w40 go from 13.7 to tens in 4k miles but this one will hold viscosity better, as the pao portion is more stable. If you look at this msds it shows 30-40% decene which is the pao they use. However, that uoa is what it is, very troubling and we need some more examples of it in a hemi before we king it a top oil imo.

What track,and what did it run for you.

damn I love those year 300 srt8s! a guy had one where i worked at when i was getting started in mechanics and he loved to let me hear it (he had opened up exhaust and a superchips or diablo predator can tune)
I think thats where my love for dodges started haha. not long after he sold me his old 93 Dakota 318 and i beat that up for a few years before getting my 06 ram hemi

all that to say if i won the lottery i would definitely go find an 06 300 srt8 and daily it in the summer
get one of those nice mesh grills instead of those bars

That does seem odd. PAO decene shouldn't shear either.....Group IV molecular saturation is the top there is, per my recollection.
Only an ester can give you better protection in high temp, but not particularly suited to shear loads - more for rolling loads as in hydrodynamic machine elements like roller bearings and bushings. Not good on cylinder walls.

Bedliner for house roofs, they are so confident they are even using this on a flat roof. Just for practical reasons i have no idea why all roofs arent white. I just sprayed my wifes rav 4 white on the roof, it is cold to the touch on a 80f day and the hood is almost too hot to leave your hand on, while parked. so beneficial but here you cant find white roofing. I like this idea so much when it comes time to get a new roof I will be calling rhino and seeing if it is available. 14 years in my bedliner is like new, I bet a white bedliner roof would last a lifetime plus...
