i have had bad experiences with wix, a company i worked for ran there filters and we had 2 f350s with less then 10k on then burn up a engine because of oil bypass problems and one f450 with the 6.4 leaned out and melted a turbo cause there fuel filter is the wrong size and allows unfiltered fuel into the injectors which clogged them, just my .02 cents

 

NAPA Filter (#21626) and Kendall 10w30 Semi-Synthetic High Mileage. It's what we use at my work...

 

i run diesel oil in my cbr 600rr. you can drive it for like 7000 miles. plus its slick ****. when i first put it in the clutch would slip a little when i got on it. then after about 100 miles it stops and ran like a champ. as for my jeep havent done oil yet but ill probably use royal purple or mobil 1 synthetic

Everybody does understand that 5WXX flows quicker to engine parts than 10WXX when the engine is BELOW normal operating temp, right? Also, everybody does understand that 0W30, 5W30, 10W30 and SAE 30 are the same viscosity when the engine is at normal operating temp, right?

 

Jeeps specify 10W30 only. This is because they need a little more viscosity when cold to keep a protective film on the cylinder walls.
