the Oldsmobile Custom Cruiser is based on the same body that the Buick Roadmaster SW and Chevy Caprice SW used, meaning that it has a 5000 lb towing capacity if already equipped with a towing package, and 3500 if not.
The 1990 Mazda 626 has a towing capacity of 750 pounds. The manufacturer recommends that you never exceed the towing capacity.
3500 lbs towing capacity according to endmunds: http://www.edmunds.com/used/1990/nissan/truck/1552/specs.html
The towing capacity of a 1990 Ford F-350 with a 7.5L V8 is approx. 12500 pounds.
What engine?
3500
Isuzu elf 250 1990 gross weight ?
2000- 3000 lbs depening on the gear ratio
Really depends on the rear end gearing and type. Typically 2000 max unless you have a towing package then I believe it can be as high as 4000.
The same for a Cherokee of that year, i think around 3500lbs
2,500lbs.-3500lbs.
if its a 1500 about half ton if its a 2500 about 3-quarter ton if its a 3500 about a ton
Typically it depends on the size of your engine and what type of a drivetrain it has. My 90 has a 305 that I put in and I dont have any problems towing large trailers. If you have the 4 cylinder, GET RID OF IT!!!
