A little off subject but here goes. If you are using mobil1 full synthetic how long would you go between changes. I just don't think that 15k would be good. Thanks

I go 7500 between changes on both my vehicles. Both have over 200,000 miles and no issues at all.

Id atleast swap the filter and top off at 7500 miles if you try to go 15,000. I only go 4000 miles between changes either way.

Depends upon the filter. Good quality filter will go the 10k. You should cut them open to verify how they perform.

I used MC and MC filter for 5500k changes and my lab reports were excellent. I've switched to M1 5-20 and Pure 1 filter and am doing a yearly about 8k change.

I've used M1 and P1 on wife's Armada with 7500k changes and after 100 and d 4 oil reports....stellar.

Mobil 1 High Mileage full synthetic 5W-30 with pint of Kreen every thousand miles. Oil gets changed based on when the oil on the stick is very noticeably dirty, not based on mileage. Stick gets pulled and checked weekly.
