Im just looking to see what others think of amsoil that have used it and then used in a 22 Ford 6.7? Ther is a lot of things i like about syn oil's and there is no 10-30 full syn available around me.
That must've been recently updated, I could swear Rotella T6 15W40 didn't have the ford approval a few months ago and now it does, it was like ford really only wanted people to use 5W40 or 0W40 if they were using full synthetic and not 15W40.To not have any warranty issues with Ford just use something on the list. Plenty of options available.
Currently it is very hard to find oil i would use on the shelves. For my first oil change i always to them early. I had to go to 3 stores to get the all the motorcraft oil needed.Use the AMSOIL with confidence. Quality oil is hard to come by on the shelves. May as well have it shipped to you.
On my last 2 6.7's there was not benefit to running 5/40 when having the oil tested vs 10/30 the 5//40 was not much of a noticeable difference i cold feel a bit of extra drag. I notice that stuff way more then most, but on a different truck the 15/40 you could rely feel this thickness and i did not like it at all. So i want to find a syn 10//30 and as why i was looking for amsoil. The manual states CK-4 as long as it has that spc. that is all that rely matters. If i don't go syn i would stay with the Motorcraft 10/30I'd just use Rotella T6 5W40 if you want syn oil, it carries the Ford approval and is about half the price of Amsoil, which is a pretty big deal when you're using 4 gallons a change. Since you're in socal, you could also use 15W40 and it should be all good, since you're fine using Amsoil which doesn't have any approvals, you could use 15W40 Delvac Extreme full synthetic or even 15W40 Rotella T6. Although for the problems people run into with these, under warranty I highly suggest sticking to the manufacturer approved oil just incase you have any issues.
I was just asking others experience with Amsoil is what i was looking for.So get the Amsoil 10w30 and be done with it . You put in motorcraft . Why would a 100% synthetic not be good enough .

Amsoil is the best. Question is, do you really need the best?Im just looking to see what others think of amsoil that have used it and then used in a 22 Ford 6.7? Ther is a lot of things i like about syn oil's and there is no 10-30 full syn available around me.
Sorry but I don't think they make Signature Series in those two grades.Have used both Amsoil 5w40 SS and 15w40 SS in a 2022. All good.
My apologies, must be overtired. Both grades are available in SS diesel oil. Sorry.Sorry but I don't think they make Signature Series in those two grades.
