I only get 17 overall and 22 on the freeway.
about 22- 27 mpg highway
The 1999 Isuzu Rodeo uses 5w-30 motor oil. The oil should be changed every three months or 3000 miles of use.
Most cars today used dual cam or more for power efficiency and lower gas emission for longer mileage.
DOT 3
80w90...with a diff additive for the rear
The starter is located on the passenger side of the block, kind of hard to reach and a pain to remove.
If it's auto it's DEX III, manual is 5 W 30
Automatic is a gm 4l-30e unit.
replace with 30w engine oil. anything heaver will burn out trans bearings.
This has a r134 system after 1993 was made standand industry wide to quiet the epa issue with r12
what type of oil depends on how many miled are on the vehicle, my rodeo has 160xxx miles on it so i use 10w 30 High Milage With a qrt of Lucas Oil Treatment and it still runs great and gets great gas milage.
My 1990 Trooper has a 2.6 L 4 cylinder engine, has 162,000 miles, and has always averaged 23 mpg. 16 city/21 highway.
on the highway doing 100km/h i get 16l/100k. i have a 02, about 7000lbs with ladders on the roof.
