i always use Mobil 1 synthic (hense the spelling) but anyways wat is the average oil change , do you think im wasting my $ changing it every 3,000 miles ?
From what I understand it mainly will cause seals that are already leaking to leak a bit worse or develop new leaks that are caused by seals that are "on their way out". I personally run synthetic through everything I own that is higher mileage and have had 0 problems. I figure it's a justification to fix those already leaking seals or find your weak ones.ive heard if your motor is high mileage and is used to conventional it can be a bad idea to switch to synthetic what do yall think?

is 104k too late to change to synthetic in these things?
I have to go back and look at my Jeep's Owner Manual, in other vehicles I own/owned the Owner Manual had a Normal Service Schedule and a Severe Duty Service Schedule. The Severe Duty Schedule description was things like taxi, police, service vehicles, idling more than 30 minutes during operation, operating in dusty/dirty environments, high or low ambient temps, towing, high loads, heavy acceleration, Heavy Traffic w/ lots of Stop & Go, etc. Normal Duty excluded those things, plus most trips greater than 25 miles between starts, etc. Basically reading the descriptions, you get the impression that anything other than "Little Old Lady Driving" for "Long Sunday Country Drives" pushes you into Severe Duty Environment. Most severe duty schedules I've seen are 3k mile oil changes...The factory recommends changing the oil in the 4.0 at 7,500 miles under normal driving circumstances (what ever you interpret normal to mean).
