1. 2013 F150 XLT Supercrew 3.5L Ecoboost
2. Owners manual - 6 qts Motorcraft SAE 5W-30 XO-5W30-QFS
3. Shreveport, LA (it gets hot and humid)
4. I like to let the horses run on a regular basis, like to hear the tires chirp!
5. daily drive - 10 miles to work, takes 12 - 13 minutes with about 7 miles being interstate
6. no problems
7. prefer syn
Any suggestions?
First -
Second - my suggestion would be to read a LOT more before you make a decision on what you're going to do here.
Last - realize that what you "want" and what the engine "needs" are often two totally different things.
If you "want" synthetics, and I presume you'll follow the IOLM, then just get whichever one is one sale that meets the Ford spec, found in your manual.
The 3.5L EB engines tend to have issues with fuel dilution; most DI engines do. But that does not stop the 3.5EB from running well or wearing well, despite the fear mongering here. Because of this, you're likely to OCI at least with the IOLM, if not sooner based upon some preconceived notion you have. And that's fine. But doing so does not necessitate the use of syns for your application, nor does your area.
I once attempted to get a good study program going on these engines, but everyone here who offered to participate wanted to run their own plan, and not stick to the protocol. Hence - the study never happened. Too bad; could have been very interesting and revealing. In the absence of that information, I say for the purpose of warranty coverage just stick to anything that meets the Ford spec and OCI with the IOLM. Past that, any lube will suffice very well, and the difference between brand products is going to exist in your head more so than manifest into a performance difference in the crankcase.
