Which should i use in my 14 5.0 coyote with 186000 miles, light bolt on mods. Currently running the xclean efe 5w30 but thinking of switching up to the 5w40 xcess

Not real familiar w/that engine outside of being put into the F-150's. In general, A 5w-40 should work just fine but a quality 5w-30 should work well too. If your temperatures allow it you also have 10w-30's that could serve the Coyote's needs. If you're pulling something heavy on a regular basis then I'd opt for the 5w-40.

Not pulling anything heavy with it atm but i like to do heavy pulls in it every so often, thanks. The xclean 5w30 is C3 and the xcess 5w40 is a3/b4
 
Nice clean looking truck. Both are good and you'd be fine using either or using any other off the shelf euro 30/40. 3.5 hths on that 5w-30 and 3.7 on that 5w-40. That's a lot more than the usual 2.6-.7 the 20 grades have and they're better blended in other aspects.

I'm using quaker state 5w-40 at the moment in my 2021 with the 6.2 but I've used pp euro L 5w-30, both castrol and mobil in their 0/5w-40 in my other vehicles but not their 5w-30 euros but that's just because i haven't gotten to trying them. Frankly they're all gonna be the same in being more than good enough for both of our trucks calling for a standard 20 grade.
 
No oil is “100% synthetic”. The Mobil 1 product Overkill is suggesting is just as synthetic as the Motul 8100.

Have you tried the 0W-40 to see if it burns in all your vehicles?
Mobil 1 is not near as synthetic as motul mobil is a full synthetic motul is 100% synthetic
 
Motul 8100 is 100% synthetic. Why would i run a 0w40 in vehicles rated for 10w30, 5w30 or 20w40?
As for the question, it is because an oil’s winter rating is not related to the operating viscosity. There is no technical reason you’d avoid a 0W-40 if you’d use any 40-grade. Plus the oil Overkill suggested is one of the best oils money can buy with multiple demanding manufacturer approvals. The price is very reasonable at Walmart.
 
Funny how marketing materials work. You should check the latest SDS to see if it is 100% synthetic. That may be a better technical source than your post.

Also check for that whole “100% ester” thing. See what you find and report back.

If you’re really into this go ahead and check out the composition of Mobil 1 0W-40.

@OVERKILL may wish to comment as well.

Some Group III and some Group II bases and an antioxidant. An ester if present may not be required to be listed if it is non-toxic, but given the other ones listed the concentration is low. An FTIR posted here a while back indicated about 1% ester.

Mind you it’s not a bad oil. It’s just quite expensive for what you get. You’ll do just as well with something from Walmart. If you don’t like Mobil 1 then your Walmart may have Pennzoil Euro L which is another comparable product.
 
I dont know how to read sds

That's showing you:
CAS 64742-54-7 - 25-50% heavy hydrotreated Group III base oil
CAS 64742-54-7 - 25-50% different heavy hydrotreated Group III base oil

An example would be SK's YU-BASE 4/5/6/7/8 family that all share this CAS #.

So it's majority Group III based.

In comparison, here's M1 FS 0W-40:

That's:
CAS 848301-69-9 - 25-50% GTL (Group III+)
CAS 68037-01-4 - 25-50% PAO (Group IV)

So, in terms of which one is more "synthetic" it's M1 0W-40 by a rather wide margin.
