0w20 vs 0w30 in my Dodge Challenger V-6?

He has entered the oil viscosity rabbit hole. 😄

OMG! So true! I'm doomed! Honestly, I'm overwhelmed with data sheets and trying to learn all the oil jargon. It's like a second language!

I'm just surveying the wisdom of this forum. I'm amazed at the options and "science" of motor oil. So many things to consider.

Be very careful.........

Like I said I use 0w20 in Louisiana for my Caravan. Oil pressure is perfect and flow is better at startup. I have had it to 6500 rpm on more than one occasion as well as idling and the dreaded Eco mode on while below 45 mph which is 90% of my driving. Change Oil at 200 hours without worrying as I average less than 20 mph over last oil change.

Does i?

Yes you do.

@digitalcassidy you should know that @blufeb95 talks about the relationship between oil viscosity and temperature, and he is right. The winter rating will not impact you if you operate the vehicle in a hot climate.

Yes you do.

Lol... I'm getting some good milage out of this typo!

Hopefully, you're getting the answers you're looking for as well.

I've recently read that the thinness of the 0w30 might be "better" during STARTUP as it flows throughout the engine and that it might circulate more efficiently before reaching "Normal" operating temperatures, where then it will offer better protection from Summer heat.

None of that is true.

None of that is true.

Especially in AZ summers as the OP eluded to.
