Just a pole, I have a 2003 6.0 and I am just wondering what owners experiences with the 6.0 with engine oil. viscosity and synthetic or not...I am in Vermont

 

With your location......5W40 synthetic year round

 

Ditto on the 5W-40

 

any sugetions for what brand to use?

 

Valvoline Premium Blue or Mobil1. Both expensive but the best in their class.

 

We "limp" along with Shell Rotella 5W-40

 

I use the Rotella 5W40 with no prob. We don't get your winters but 105 or more during the summer and it works great and 19 bucks a gal. at Walmart.

 

+1 here!!!

 

mystik JT8 syn blend here and can get either 10w30 or 15w40

 

I've seen the mystik and was wondering how it was. I know their red grease is and always has been the shtick. Ever had an analysis done on it?

 

If you hurry NAPA has the Valvoline 5w-40 syn on sale at $17.99/gallon. BUT, sale ends today (9/30). I just wiped my local NAPA out of 12 gallons. Actually called Saturday and had them order it in for me. That should hold me for a little while. Now, if Pep Boys would get off their a** and put the Fram filters on sale again, I'd be all set.

 

I'm sure Pep Boys won't fall for that one again....I'm going to order up some NAPA oil today.

 

Mobil1 5w-40 Syn

 

I agree, you'll never see that sale again on $3.50/ea. Fram filters for the Powerstroke 6.0l! I bought 15 all together thru the sales they had. I was down to 11 and panicked and bought 2 for $9.50/ea. when K-Mart had a recent sale.

I like the Amsoil AME 15W-40 oil. I've used Schaeffer's 5W-40 and Shell Rotella 5W-40, and the Amsoil is a better oil. It is also the most expensive. I can go twice as long on the Amsoil before I have to change it. So it ends up costing less!!

 

To answer your question NPC never had a analysis done but I know my truck sure loves it, queiter and smoother than the motorcraft or rotella for me. The mystik is a syn blend / CJ-4 rated think it is $22.00 for 2 gal jugs. Each person has the brand they love and rely on. User preference
