can anyone give a general consensus on what oil to run in XJs? there are literally hundreds of pages on this. I'm sure this won't be simple, but I'll throw it out there anyway.

Mill

 

Nothing to see here folks...Move along

 

Possibly more important than motor oil for the Jeep Cherokee...

 

Haha.

 

There are hundreds of pages because there is no general consensus. The easiest thing to do is read every page and form your own conclusion.

 

There ain't a doubt in my military mind!

 

 

Aw H@ll I'll say it...... I read them all and switched to Rotella T 30w after it all shook out. Everything else I own (7 total) get's Castrol Oil Full Syn., except for my Diesel Pusher Motor Home and the F-350 Crew Cab Power Stroke. Yup you guessed it what they get also Rotella T

 

Right here.

That's all you need to know. Case closed.

 

i hate doing this... I run Rotella 15w40 and a WIX filter..

 

It actually is simple. Anything SM or better that's on sale and isn't bundled with a Fram filter. (because you'll want to use it since it's included and shouldn't because it's junk)
From there it's really just personal preference. 5W or 10W 30 should do.

 

Yes

I heard FRAM is really a Cylon operation.

 

Fram isn't the only junk filter out there.

Please patronize the suppliers who have never stooped to putting marketing over quality like Wix, Napa and Mopar

 

^X2^ I have cut open a lot of filters over the last 25 yrs and they are not all equal for sure.

 

Rotella T6 & Wix 51515........
