Oil change is coming due in the next 1k miles i am gonna run a synthetic this time and rev x as for the first time.

Im just not that familure to the whole diesel world so Im not sure one what to get. California truck 90k miles never towing but driving alot so what would be the best weight for me

Just would like to know what every one is running and what every one thinks is the best motor oil

 

15/40. Many brands, not all the same

 

I realize that I am in the minority with this opinion, but I believe oil analysis (OA) is your BEST tool! Rotella T-5 conventional oil and a Fram filter went 10K in my 2003 and could have gone farther given the OA results. I wouldn't recommend running 10K without an OA, though.

Several Bombers are going to tell you that I am as high as a kite and that 5K is the magic number. IMO, at $80/5 gal bucket, I'm going to get the full use out of it.

 

I'm an avid 5k changer, but I also do it because of the veggie, if there is ever an issue where I have an injector leaking or anything like that, I'll catch it sooner (not as big of a deal when diesel mixes with motor oil, but when veggie and motor oil mix, it looks like tar).

I will be running Rotella T6 next change 5w/40 or 15w/40 should be good. In fully synthetic most of it is 5w/40. That should be fine.

Other popular ones for the 6.0 are Amsoil, and Valvoline premium blue, a few here and there use schaffers too. All are good oils. Stay away from Royal Purple.

 

I was just on amsoils website about to buy some synthetic oil but read in bold letters "DO NOT USE WITH OIL ADDITIVE" so don't use rev x with the synthetic amsoil?

 

I think they are talking about stuff like Lucas oil additive, I run Amsoil with the bypass setup and I change oil every 25k even when the OA says its still good, the bypass system filters out the sutt, cost a little more up front but saves in the long run, before you put Amsoil in it do the flush with there product.

 

Scheaffers is the only synthetic I would run

 

Oil can get to be hot topic for some. I say run any good oil and see how your truck likes it. I use the Rotella T6 because it is about $20.00 a gal at Wallyworld so its handy to get. I do my oil at 5000mi, because I cant think of another engine that is so hard on oil. I know some that go way longer and I think thats fine too....for them.

 

i installed the nu Sports bypass oil filter system using the aimsoil 2- micron filter
and the Rotella T6

 

Hmm...I am confused t-5 is a synthetic blend in 10w-30 or 10w-40 flavors...so are you running T5, "triple protection" 15w40 or t3 conventional?
