Yup, I've been running the FL-1A since I have done the first oil change!

It's thrice the size of the stock mopar filter ... I think the huge filter caused the oil filter adapter to leak from bouncing around off road with almost an entire quart of fluid! haha. To fill my jeep from empty on an oil change is right around 6.5 quarts.

The last oil change was with Rotella T6 and I ran it 6000 miles. I'm going to change my Cherokee to Supertech synthetic 5-30 in November/December (whenever it starts getting cold). I'll probably have a total of 7000-7500 on it. I'm going to do a UOA then to see how it did!

Factory fill gets dumped this week @ 3500 miles. Will get UOA at 10K at a max for the new fill. Will base OCI's on the 10K UOA.

Aren't the OLM based on mileage, throttle usage, trip length, etc?
