Ram 1500 5.7l hemi .......what's everyone's go to motor oil......

Mobil 1- 5 quarts of 5W-20 and 2 quarts of 5W-30. Thinking of trying Mobil 1 0W-30

 

[Skippy722]

HPL Supercar 0w30… otherwise I like Mobil 1.

Need more info, like year.

I thought the go to was 0w-40?

That's for the 6.4. The 5.7 can run 5w-30 (or 0w-30 if you get very cold winters).

0-40 and sleep well at night. unless it goes well below -20f no worries.

0W40 can handle lower temps than -20F. A great choice for that engine imo.

Mine gets Castrol 5-20 semi synthetic high mileage at 226K and uses no oil or ticks. Previous owner used it so I did not change. I do used the large ford Motorcraft filter. It is longer and easier to replace.

 

[OVERKILL]

Running @High Performance Lubricants Super car "overkill" 0W-20 in ours with the larger 6.4L filter.

Seems like you can run 0W-40 in about anything.

Seems like you can run 0W-40 in about anything.

That is my way of thinking as well.

my son is running Mobil 1 5w30 in his 2023 5.7L Hemi.

Just my $0.02

 

[Plumb Bob]

Currently Delo XLE SB 15W-40. Also, I use Euro XW-30/40.

This would be my choice as well. Can't go wrong.

 

[THORROMIG]

Pennzoil Ultra Platinum 5W30 SP is another quality oil to try. I have PUP in 2 of my vehicles and am very pleased with multiple aspects of this oil.

 

[ATex7239]

Ran a tuned 5.7 on M1 and VL FS 20’s and it ran like a top. Electrical issues plagued it though.

Mine says 5w-20 on the fill cap. I will not use that junk so I was using 0w-30. Now I just go the easy way and use 5w-30.

“Junk” you say. lol

Same, I went from 0w-20 to 5w-40 in my 2021 by the 14k mark. That junk made the engine burn oil and loud at hot idle. Doesn't burn a drop and it's dead silent to where I only hear the gdi pump now. Also hated how it'd splash like actual water when draining the sump making a mess of things.

Because you live in hot Texas the reason you skipped over trying the 5w30 first?
The jump you made was huge...... cst roughly 8.5 to cst roughly 14.5. I would have began around 11.5

Is your 5w40 SP?
