which means what exactly?

 

Doing an oil change tomorrow gonna use shell Rotella 10w30 as I'm searching all I see is diesel oil for the 10w30 or T5 ???

 

Rotella is a diesel oil (it is also rated for use in gasoline engines).

 

oh ok, So i did not know that. So i am guessing its fine to put in my xj? there is t5 and t6 i wanna use 10w30

nevermind i now finally read into it. answered my question.

 

Rotella rocks. Good enough for turbocharged diesels and good for the 4.0. Cleans sludge out like nobody's business. Watch how soon your oil turns black and the sludge melts off your rocker arms by shining a light into the oil filler hole!

Haha nice man I'll be doing this today.

 

Your basic question should be whether you want a dino/synthetic blend (T5) or full synthetic (T6). I assume you have it sorted out.

 

Why is it u r going with 10WXX?

 

^^^ X2

 

Ok today the oil was changed with t5 10w30 rotella wix filter cleaned my IDC sensor.checked my other sensors.took of my muffler exhaust because there's a huge hole in it and getting new exhaust soon."so loud now " and pained my wheels and took all trim and corner bumper stoppers off.after doing the oil change with new filter it runs great on the road but at idle and when I slow down the whole jeep shakes it's super rough at idle.still sounds like it is misfiring. I don't know what to do it's driving me crazy.

 

Me and my brothers jeeps looks much better after I did the wheels

 

I'm guessing "IDC" = "IAC"?

Sounds like you mighta knocked it. They're very sensetive.

Occastionally the PCM can forget the IAC's position and idle wrong. Try disconnecting the battery for a few minutes and it'll reset/relearn it.

 

I had the battery disconnected when I cleaned it and yes I hit the wrong letter IAC.but I do have a aftermarket CPS on my jeep as we'll.

 

What about throttle position sensor I did not check that one.i also have not had a compression test done
