Most recommended engine oil

So living in GA it's not uncommon to see high 20s in the morning and nearly 70 in the afternoon around this time of yr. This will be my first oil change on my new to me truck (2017 CTD 4X4 tradesman). I plan to keep this truck for a very long time. That being said I'd read several posts and the general consensus seems to be Amsoil, T6, or valvoline seem to be the preferred oils? Of the 3 the T6 seems to be the most common brand around me but should I go with the 5w40 or the 15w40 version? Thanks,

This is what I use :

Changing it more often vs buying the others and running it for 15k. Not everyone will agree but it’s what I do.

I've use Valvoline Premium Blue. Only oil I have used since taking delivery. As long as oil meets specs, use your favorite flavor/brand.

I have not heard of that brand of oil before, but does not mean it's bad oil.

I change oil when notified by the EVIC. What does your owners manual recommend?


15/40 for temps above zero degrees, and 5/40 for temps Zero and below.

Not really towing, and not very heavy, I stick to the 15,000 mile thing, that's usually one year, its been 4 years now and truck hasn't blown up or use any noticeable oil at change time. I just us the rotella t6, but last year at friends farm, used the John Dear 50+ 11... truck liked it just fine, no diff from the t6. Both are/were 15/40. I am tempted to try the synthetic, for the heck of it next time. When I had Harleys, they loved the full synthetic, vs dyno oil.

All of mine have only seen Valvoline Super Blue, several trucks lots of miles zero issues, and I use the dreaded Fram filter too.

If it was up to the oil companies they would have you changing it every 1k miles not every 15K. 15K is what Cummins recommends. But changing it every 5K will not hurt anything other then your wallet. Even at $8 a gallon for that oil, that works out to $72 for oil every 15K miles not including the filters.

This is a dumb question but I know Cummins recommends 15w-40 for higher than 0 degrees and 5w-40 for all around temps and over 0 degrees -

I have a few gallons of 5w-40 T6 on my shelf, we rarely get down to 0 degrees here in NC, I think I'm just going to use it as opposed to going and buying 3 more gallons of 15w-40?

I have always run just plain old Rotella T4 15W-40 for the past 21 years . With this 2014 Ram I just followed the manual on oil change intervals. 6 months or 15K. I never go anywhere near 15K , so its always every six months.

Being off warranty, I am going to go every 12 months ,and probably T6, or whats on sale

I'm in Georgia as well. I've been running the Valvoline premium Blue 15W40 since day 1. Just did a change a week ago. Napa has it on sale for $11.99 a gallon. Buy on line and pick up in your local store. I do mine every 15K (when the oil indicator says it's time)
