Going back to 0w-20 for the winter

[CKN]

Agreed

Well....unlike many on here I don't try to out guess the engineers that designed the truck. In addition-the truck was certified at the time of purchase and has a 100,000 mile power train warranty. If you follow my posts at all-I do a ALOT of high altitude towing. Previous trucks that spec'ed the same oil never blew up.

An educated guess is that I have towed an accumulated 30,000 miles -most which running what most call "thin oils". Most in 5.3's running 0w/20.

The L83/L84 has a very stiff and concentric lower end (6 bolt) - and oil jets/coolers were added to control temperature …
The AFM/DFM concerns me some - but one of our engineers is well past 200k on M1 AFE (0W20) with zero issues …

It's not the engineers. It's the bean counters trying to get that cafe number as absolutely low as possible with out having to recall a million engines.....

But they just did lol

But they jut did

I bet they could have hid it well enough with 30wt to avoid the nearly 7 figure engine recall.

Their using the 20W due to CAFE / gas mileage / etc. Every manufacturer has to meet CAFE standards , weight standards, emissions standards, mileage standards. That's why all these new cars are like beer cans. You lean on them, and now you have a dent to look at.

Be more specific, I know what you are talking about-but I don't like "hit and run" posts.

What year beater do you drive?

CKN, My beaters are old. Sill have some metal on the body. 03' Solara / 4cyl / 5W30 --- 06' Camry / 4cyl / 5W30 --- 13' CRV / 4cyl / 0W20. My moms cars is new. 2024 Toyota Cross / 0W16 / Tin Can / She hates it. She's scared she may dent it with her shopping bags. Paper thin skin on it.

Body of the car does not need to be tick, it is thr frame that need to be stronger and pass small overlap crashes.
Older heavy thick cars are not as good as newer cars in crashes. They put metals on not so important place, just added weight.
I like that some newer cars even use aluminum plate on the trunk, hood and probably door skins.
The same true also with thinner and thinner oil like 0w8. 0w20 is a normal oil that can deal with a good turbo engines, not crappy engines..

Well, mom is old, and old school. 85 yrs old. Can't teach an old dog new tricks . She likes a heavy metal body. I said " Ma, they no make them like that no more" She says " Frigging P.O.S. "..." Plastic everywhere !!!!! " I just laugh

 

[Urshurak776]

Doubt it will make much difference. I would stick wih a 0W-30 year round.

I'm an hour and half, give or take from you and originally from Flat Rock, so essentially the same weather. I probably take the same I75 route that you do as well going to FL. I'm doing something similar but am running 5w20 from June through Oct and switching back to 0w for the winter. I know, I know, 5weight will start at -40 and all that. I can still tell a big difference between a 0 and a 5 at minus 10.
