My mechanic is telling that he wants me to use schaeffer 15w/40. What do you recommend for a 2018 F250 Powerstroke? I live in southern Wisconsin.

Schaefers is good oil. Mail order it and carry it in. See what he says when you supply the oil laugh

Difficult to answer unless you provide more info. We know you need cold starting capability. How much do you drive and tow?

What does it spec? Do you have an auxiliary oil cooler? How much do you tow?

I would run a 5W40 synthetic that is Ford approved. You will need to check the Ford document on oils approved for the Ford Powerstroke (this is all about CK-4 oil).

Rotella T6 5W40 in the containers that pass the Ford spec would good.

Delo 5W40 is also good. I see a lot of that oil that is CJ-4 on shelves at Walmart. Stock up on some of that. The CJ-4 passes the Ford spec. But if its CK-4 then you need to check to see if it passes the Ford spec.

Yes, make sure it has the Ford spec WSS-M2C171-F1, a lot of CK-4 oils do not meet the Ford spec.
Given you are in Wisconsin, I would look at a 5W-40 weight.

Read the owners manual and use an oil with the specs recommended by Ford.Buy an oil from any of the major companies.

You really don't need your mechanic to change your oil.
That said I just got out from under my SUV now and changed it so I
understand.......


Ford gives big deal coupons on new trucks and you couldn't even buy the oil for what they do it for. They used to take 13.5 quarts. Don't know what your new one takes.
But an oil change from an independent could be really expensive.

I suggest asking Schaeffers and getting their recommendation. We need to be kind to Schaeffers around here, the Bob (RIP) in Bobistheoilguy was a Schaeffers rep.

Unless you use the truck for towing and by towing I mean more than on the weekends you don't need a 15w-40 or 5w-40. If you look at previous threads there are plenty of powerstrokes running a 10w-30. 10w-30 as far as I know is factory fill. I've read alot of threads where 5w-40 shears down to a 30 anyway while the 10w-30 stays in grade. No need for expensive synthetics if you're going to change oil according to the owners manual and not push gvwr.

My dad just picked up a new 2018 F-250 I put Rotella T5 10w-30 in it for him at 4400 miles. He tows 15k on the weekends. Will be keeping a UOA record on this truck as well. By the way there are quite a few c&p of filters as well, take a look. I know the baldwin b7379 filter is wire backed synthetic as that's what I put on.

Did he wait the 1000 miles before he towed?
That was tough on me, the wait smile

Yes he did, I think a vacation was taken shortly after purchase and that was about 1500 miles.

Schaeffer's Supreme 9000 series is still CJ4. My Jeep GC Ecodiesel uses the S-9000 5w40 and my LBZ Duramax uses the S-9012 10w30. Great oil at a reasonable price...

FYI... The Duramax pulls our 10K# TT throughout the Idaho Rockies..

2016 PSD owner here.
Schaeffer is a fine oil no doubt. So is Valvoline Premium Blue and Rotella. All of those vendors 10w30 are on the list.
I'm in the camp of a 10 w being good to 20 degrees F, so if you get colder than that in Wisconsin, consider a 5w40. Your truck going to a cold climate may have come with a block heater. If so, I would stick with the 10w30 year round. Seriously, you'll find the 6.7 will start and run in any temperature you are brave enough to walk out into unassisted anyway.
I'm running Delo 15w30 in mine, but it gets stored along with the camper from October through March, so no cold starts for me.
