Poll- What Weight Oil do you Use?

[Burla]

We have seen Ram recently move eco diesels to heavier oil due to internal issues, and we have similar issues with hemi's and Cam/lifters imo. So just curious to see a poll on oil weight. If you go heavier then 5w20 have you ever had any issues? Trying to see how many people have had any issues with a heavier oil with these mds engines that are supposedly dependent on 20 weight oil. The poll closes in a year and you can change your vote if you end up with a check engine light.

Thanks in advance for your participation.

I started with 5w20, then moved to 5w30, and then I went from 5w30 to 10w30 and no CEL's - so far.

I have 5w30 redline in mine and no issues. Sounds quiet and smooth.

I started with 5/20 but since then I've run PP, Amsoil SS, and now M1 EP all 5/30's with no MDS problems. The 5/30's also cured alot of the noises I was getting. Little to no fuel milage difference and if anything engine runs a little cooler.

I have a 2500 with the 6.4 so they state ONLY 0W-40 & special specs of which I think there are only 2 oils out there that meet these specs. Something to do Unicorn Tears?!? LMAO

Using 5-20 pup. So far engine is smooth and quite.

 

[grizzstang]

Running 4 PUP 5W20 and 3 PUP 0W40 right now (around a 3W28) but I will be changing the oil in the next few weeks.

I might run 7 PUP 5W30 or I will mix again but run either 4 or 5 of the 0W40 because is has more moly than the 5W30.

I have around 3700 miles on my currant OCI and the motor is nice and quiet on my mix.

Dodge Ram 5.7= 5w20 Amsoil ss
GMC 6.0 = 5W30 Quaker State Ultimate Durability

Both oils are serving/served me well.

You may want to change the title of this poll to 5.7 and/or 1500 model specific if that's the data you're looking to collect. The 6-banger and 5.7 only account for 2 of the 5 engines installed in Rams across the 4th gen lineup. Coincidentally, they are the only two in which the manufacturer has specified the use of a 20wt oil.

QSUD 5-30. No problems.

burp, I mean bump

Going to update my previous post. Have now went back to 5/20. The 5/30 ran good, no cel, everingthing good except cold starts. On cold starts it sounded like rocker arms running dry till the oil got pumped up there. Put M1 EP 5/20 in and no more noises. SS 5/20 on the shelf to go in next oil change.

So what has been your temps on your cold starts with the 5w30. ?

Anywhere from 50 to 15. The temp didn't seem to make that much difference. On the initial start it would be quiet for for 4 or 5 seconds then you could hear the rockers for a couple of seconds, then it would get quiet again. Outside temp didn't seem to matter. On a restart after engine was warm it wouldn't do it. Now with the 5/20 everything is quiet.

Currently running Amsoil SS 5w30 with no issues. Thinking about trying Redline, just for giggles.

 

[nateinva]

Running PUP 5w30 now but just started a subscribe and save on Amazon for Redline 5w30 and RP filters. We'll see how it goes.

 

[grizzstang]

Switched to PUP 5W30.

It was on sale 40% off.

I may just stick with it as I already run it in our Jeep Wrangler.
