Try looking in the owners manual for oil viscosity type. Depends on the temperature range where you live. Most cars now use split weight. The 96' has hydraulic lifters, using a straight weight oil will cause irreversible engine damage. The oil is too thick to run through oil passage ways. I never have less than freezing outside temperatures here so I use 10W-30 with my 96'. I use Castrol brand oil and I put in some Slick 50, or Prolong, or QMI for long term protection every 50,000 or so. I have 198,000 and still kickin'. Change oil and filter every 3,000-5,000 miles. Depends if you drive long say 30 miles one way to work a lot, use the 5,000 timeframe. Short trips go with 3,000.
