Lets talk oil

[Hayden]

I have been told to put synthetic oil in my 2006 6.0 so what kind do you guys use. It has 76,000 miles on it and the guy before me had the oil changed every 5k miles at the ford dealership with motorcraft oil (he gave me a stack of service records). I have always been a motorcraft fan and seen they have a synthetic oil so thats what i was thinking about using. what kind does everyone use?

I use amsoil 15-40 but i think I'm going to switch to 5w-40 for the winter. Do a search on this there is a ton of posts on it. I don't know too much about the motorcraft but I'm sure it would be fine.

Rotella T6 5w40 year round. Starts great(for a 6.0) in the cold and holds up to high summer temps with towing.

I use 5/40 Synth year round. T-6 because it is affordable. Next change, I might try Schafers 5/40.

I drive it in zero degree weather, I drive it in 100 degree weather. Some days are easy, some days hard on it.

Always starts easy! My truck will start with no challeges 16* or above. Anything below 16* it is just louder. I started it at zero last winter not plugged in and started better than some of these things do in 50 degree weather. My 58V FICM helps a bit but I give most credit to the oil. And now RevX. I run RevX not because I have a problem, I run it because my truck starts like a gasser when I use it. I like the stuff so much, I bought some for my boat! HA.

Either way, there will be many that tell you to use different brands. Some different classes of synthetic. The one thing just about everyone will agree with, go with 5/40!

Dude..... Today was cold in Pittsburgh. You should have heard the 7.3 OBS starting up next to me at work today. It was rattling my truck. I actually like the sound!

Our 6.0s start like a dream in comparison when cold! Now the 6.7s start like a knife thu butter!

I use Mobil 1 synthetic 5w40 with occasional doses of Rev-X

Haha yeah, 7.3's sound like they dropped a piston when its cold.

Im used to my trusty 24v Cummins still in this cold. This is my first winter with the powerstroke and it definitely doesnt like the cold imo. Starts fine, sounds fine(little stiction when cold, some blue smoke for 20-30 seconds when oil temps are in the 40's). My cummins started like a warm summer day in the dead of winter. So thats my benchmark.

Good point!

Where do you get REV-X?? Coach

I get mine right from their website. I order a bunch at a time to bite the bullet.
