The 1987 Isuzu Trooper typically requires 10W-30 motor oil for its engine. It's important to check the owner's manual for specific recommendations, as oil viscosity can vary based on climate and driving conditions. Additionally, using an oil that meets API (American Petroleum Institute) specifications is advised to ensure optimal engine performance.

The 1993 Isuzu Trooper with the 4L30E 5-speed manual specifies API 5W30 for the transmission. API SJ (or above) is compatible with this transmission.

Would have been built for R12, can be converted to R134a.
it could be an alternator problem,is it an automatic type heater(no manual levers)
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 ...
I have a 95 Isuzu trooper 3.2 dohc. --On line you can bring up the chiltons manual through the library (for free) here in Washington. -You just need a library card. When I was looking at the recall and revision page in the chilton manual it had an entry of a revision for the oil type to help remove the ticking in the engine that is caused by a varnish build up of the oil and it suggest to use 0w30 to get rid of it. I don't know what the normal is though it is probably 5w30. Hope I was able to help.
5w-30 is the best to use on the trooper, i take it, it is the 3.0DT? Its a very fickle engine and doesnt like any other type
The 1998 Isuzu Trooper typically has one catalytic converter. However, some models may have a second catalytic converter as part of a dual exhaust system. It's essential to check the specific configuration of the vehicle, as variations may exist based on the engine type or emissions standards.
