What type of oil and filter do you use

These engines prefer a synthetic 5w-30 oil. I would go with either a Fram Tough Gard (TG2951...i believe), or higher quality oil filter of your choice. For future reference, and you'll need it, if you have the automatic transmission NEVER EVER let anyone put DEX/MERC in your transmission during a flush. ALWAYS ALWAYS use Mobil ATF 3309 or equivalent. Toyota Brand fluid has an equivalent that's cheaper and easier to potentially find. After some issues myself, I've learned ;)

Depending on how much you care for your car and what your willing to spend. I use either Mobil 1 or Royal Purple Full synthetic with a Wix or Mobil 1 oil filter. That's as top notch as you can get and now Mobil 1 is offering a new Full Synthetic that is good for 15,000 miles.

My tracker is a 98 n I accidently bought a oil filter that's for a 91. Does that matter?

Where is the oil filter on A 2004 CHEY Tracker

Have over hall the Tracker 2000 New oil pump TK520 and it broke off the timeing guard for the upper timing chain what caused the problem had replace it and the same problem arrived

K&N or Mobil 1, I wouldn't put a fram on my lawn mower , had 2 collapse on our high performance engines!
