Hey all - I've got a basic question many of you may roll your eyes at, but bear with me here...
I got a Jeep Patriot 2008 model last November (of 2007) and it's been great - just what I wanted out of it. It also comes with this "lifetime powertrain warranty" if you follow the scheduled maintenance in the manual. The first scheduled maintenance in the manual is at 6,000 miles, where you get the oil changed, tires rotated, so forth. Here's my (paranoid) question:
I traded in a Jeep Cherokee 1994 Sport that I got new in...well...1994. I put over 250,000 miles on the Jeep (actually more like 280k), changed the oil every 3,000 miles the entire time I had it, and never had to replace the engine, transmission, or any major engine components (I did replace the rear bumper 4 times - apparently other drivers have a hard time seeing a big, "flame red" jeep they're coming up on too fast!). Point: I've always lived by changing the oil every 3,000 miles and it's worked out quite well for me.
The manual has the oil changes at 6,000 miles and these new-fangldy vehicles have the oil sensors and whatnot. I plan on keeping the Patriot for 13 or 14 years, just like the Cherokee, so should I be changing oil every 3k or just sticking with the manual at 6k? I do a mix of highway and city driving, but I never really encounter "traffic jams" where I'm stuck idling for a while. I'm not off-road with it so much but I do use it to haul landscaping supplies on occasion (cleans up very nicely, I've found).
Anyway, I'm taking it from the posts on this thread that if the change oil light hasn't come on (it hasn't) and I haven't hit the 6,000 mile oil change interval from the manual then I'm ok. I'm a real stickler for maintenance, and slightly paranoid with it being brand new, so I figured I'd run this by the pros on the forum here. Thanks for entertaining the question!
