What motor oil are you running?

[cabledog25]

I have a lifetime deal with the dealer when I bought the XK new in 2006. All my oil changes are $10.00 and I check it every time to make sure its new oil and new filter. Not sure what brand they use, but they have Pennzoil banner everywhere. And I change it every 3K miles.

You running conventional, or full synthetic?

I am running M1 5-20 & have since I bought it @ 20k. I change it between 5 to 10k Depending on what type of driving I have done (A lot of wheeling change more often)
I also run M1 for my gearboxes

Matt has a good routine down. Changing at 5k intervals makes it easy to remember and it isn't to early or to long on the oil. Just right. Plus you can work your tire rotations in along with it and depending on how long the mileage takes you in time wise, you can work your vehicle inspections around it as well. Keeps everything organized.

AMSOIL has been out since 1972 and have been growing every year. They were the first to have an API certified synthetic engine oil, that is why you see "First In Synthetics" on their site.

I've used M1 5W-20 for my Hemi ever since I bought the Jeep at 9k mi. I'm at almost 112k now. No oiling issues. I also use the Mopar filter since I can get it at Walmart along with my 5qt jug of M1. I'm also partial to the Napa Gold (otherwise known as Wix) filters. I've heard horror stories about Fram stuff.

I used to use the M1 oil filters but recently switched back to the dealer filter with M1 5w20.
