5w-30 in my 22 Charger GT

[digitalcassidy]

For those that care, I have been running Castrol EDGE full synthetic 5w30 in both of my 3.6L V6 vehicles since I changed the break in oil @ 500 miles.
Both cars, 2022 Charger and Challenger, have been running perfectly, sharing both the Arizona HOT summers with the So. Cal. mild winters. I change the oil myself every 5k and use WIX filters.
ZERO issues with both cars @ 49,000 + miles on each.
LOVE MY MOPARS!

My ‘22 GT now gets Kirkland 5w30 with Mopar filter.

You said Arizona and Ive been there. Yeah its hot! Is the local Dodge dealer using 5W30? I found a link to an auto repair place in Phoenix which is saying 20W50!

I would make a call to a local dealer and ask what viscosity they suggest for that area.

why not just continue with the Castrol edge 5w30 its good oil,and perhaps run a used oil analysis and see how the oil is performing before any thing else.

For me, dealer would be the last place to ask for oil advice! I go to YouTube for that.

Hmmm... I'm no expert, but 20w50 seems a bit much for Mopar's V6, 3.6L engine. I wouldn't do that.

20w50 can you get that in a synthetic Dexos rating?

That oil is too heavy

That oil is too heavy

Based on what? The car is already seeing the viscosity of 20w-50 and then some every time it’s cold started. A 0w-20 is as thick at 65C as a 20w-50 at 100C.

The engine sees that viscosity every time it’s started.

That oil might not play well with the VVTI system oh no a heavy 20w50 might set off a CEL or even worst explode

We should be clear though when we say an oil is too thick, that it’s only and always the 20w part and never the 50 grade part.

Even a 60 grade is thinner than every 20w, because no oil grade disparity is large enough to bridge the gap in test temperatures.

The heaviest kv100 that can even be called a J300 oil grade is 26.2 cSt.

But a 25w is allowed to go to 13,000cP at -10C as a “min max”.


At 40C, 0w-20 is thicker than a 60 grade is at 100C.

Thus, the winter rating is the only end that’s ever too thick.

If a 0w-60 existed, it would work in almost every car made.
