How often should you change ATV differential fluid?

Usually every 200-250 miles.

How often does differential oil need to be changed?

every 30,000 miles to 60,000 miles
Generally speaking, differential fluid should be changed anywhere from every 30,000 miles to 60,000 miles.

What oil goes in the rear differential?

There are two types of differential fluid. One is mineral oil, which is a natural, crude oil-based fluid. The other is synthetic differential fluid, which is created in a lab.

How often should transmission and differential fluid be changed?

Most manufacturers recommend that the differential fluid be changed every 30,000 to 60,000 miles. It is a messy job, and should be done by a licensed mechanic.

What gear oil should I use in my ATV?

The owners manuals of most shaft driven Yamaha ATV’s will tell you to use 80w gear oil of GL-4 rating. Any Hypoid gear oil (hypoid means is it GL-4 or higher rated) will work fine.

How long does differential oil last?

The oil needs to be changed every 30,000 to 50,000 miles, unless your owner’s manual states otherwise. The differential is a part in your vehicle that compensates for the difference the inner wheel and the outer wheels travel when you turn a corner.

What happens if you don’t change your differential fluid?

Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.

Is differential oil and transmission oil the same?

Differentials use gear oil/fluid. A manual transmission also uses gear oil but the viscosity may be a bit different. In an automatic transmission, definitely not; the fluid is much thinner and is called ATF – automatic transmission fluid.

What is hypoid gear oil?

A hypoid gear oil is a lubricant that is designed to operate effectively with hypoid gear designs. Most gearboxes and differentials use hypoid gear designs and the lubricant must contain EP (extreme pressure) additives to prevent wear between the sliding surfaces of a hypoid gear mesh.
