I have owned two Isuzu trooper's. and 88 and a 98. Both having higher mileage I have always used 10W-30. If your truck is burning oil it may help to get a higher viscosity of oil, but 10W-30 will get the job done.
depend on what type of transmission you have auto/stick?
0-20 mobil oil fully synthetic dont put to much ...
To add brake fluid to a 1991 Isuzu Trooper, locate the brake fluid reservoir, which is typically situated near the back of the engine bay, close to the driver's side. The reservoir is usually a translucent plastic container with a cap labeled for brake fluid. Remove the cap and pour in the appropriate type of brake fluid (usually DOT 3 or DOT 4), ensuring not to overfill. After adding the fluid, securely replace the cap and check for any leaks.
