Rotella t6

[ECDirtyboy07]

After a little discussion about what oil I use with my mechanic he states this about the T6

"Also its not a good idea to run rotella because of the high ash content and it clogging the ipr(injection control pressure sensor) which will cause a rolling idle or misfiring injectors I would use amsoil or royal purple for full synthetic and motorcraft for conventional and the weight should be 15/40 for sure with the temps in Florida."

I'm not doubting him, just would like to see what y'all have to say.

I've been using T6 for a long time now, I guess my motor is one giant ash tray!! LOL!!

I use T6 also, not problems here with clogging the IPR screen... Mine always idles fine. And in warm temps like in Florida, 5w40 will behave exactly like 15w40. The only time there is a different is in cold weather.

idk i always ran extreme blue 5-40 and got t6 this time and im having a really bad miss when she is cold before it was a slight miss but now it almost undriverable when oil temp are below 100 . and by undriverable i mean it shake and misses bad when babying it like 25% throttle max

Call Doug at gogo diesel.com in Plantation Fl and ask him his opinion.

I say coincidence.

i dont know. i changed the oil and it was night and day different. before it was a slight miss when it oil temp was below maybe 75 then it was fine now it horrible till 100. after i drove it a day or two after oil change changed fuel filter and did blue spring mod as well. fcim is good so not sure what it would be in less injector when bad while change the oil.??

I wouldn't put Royal Purple in my lawn mower. Take a bottle that's been sitting on the shelf for a while and dump the oil out without shaking it up. Now look at the crap in the bottom of the RP container that settled out while it was sitting on the shelf. Then consider your oil pan over time.

His opinion is to use the 5w-40 Valvoline Extreme Blue. Thats what he recommends. Because of that, I got off the T6 myself, and went with the Valvoline Extreme Blue just to make sure.
