Depending on the season for the viscosity; consult owners manual. Quanity; start with five quarts and check the dipstick after you ran the engine for a couple minutes to check for leaks at the filter and drain plug. Some models take more than five quarts, but you can see for yourself and add if necessary.
1999 Isuzu trooper
0-20 mobil oil fully synthetic dont put to much ...
ATF-III
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.
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?
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

It appears that the 1993 Isuzu 3.2L V6 engine has just one oxygen sensor. It's a 4-wire type, located at the exhaust Y-pipe outlet. == ==
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.
it could be an alternator problem,is it an automatic type heater(no manual levers)
