Castrol Syntec

I am SURE this has been hashed before, but the search didn't give me anything.

Anyway.....is anyone using Castrol Syntec FULL SYNTHETIC in their 5.4 Expy?

I am wanting to go to a full synthetic (overkill, probably) just be be as sure as possible that I get as much lube to it as I can. I have used Valvoline synthetic in other vehicles in the past as was pretty pleased with it, also.

Thanks!!

I am using Syntec in my 99 Eddy and it seems to be ok. I took a 1600 mile trip last week and it went thru a quart in 1600 miles.I was driving at 80mph and it was 96* out. I have never used oil like that before, I am using 5w-30 at this time but I am changing the oil this week end and I think I will try 5w-50 to see if that helps. Any comments would be helpfull.

a quart in 1600 miles???????

Personally, I think you need to look for another oil or fix the consumption problem.

Mine is a 2005 with 22,000. I expect ZERO oil consumption at this stage.

Been using Castrol Syntec since the first oil change in my 04 4X4 with the 5.4L. I have a 100 mile daily comute, and just crossed the 60,000 mile mark with no consumption problems at all, even with the 100+ temperatures of the Oklahoma summer.

My '01 expy consumed ALOT of oil prior to switching over to syn. My '06 has used syn since I brought her home from the hospital...I mean dealership. I haven't noticed any loss of oil, however, as rough at it runs at start up you'd think there wasn't a drop of oil in it.
