So, the difference between “75W90” and “75W140” is that at operating temperature, the 75W140 will be considerably thicker than the 75W90 but at room temperature they will be about the same viscosity.

How often should you change diff oil?

Usually, differential fluid is changed after every 30k to 60k miles driven. This is a tough job, so must be handled by an expert technician. Only an experienced mechanic can properly wipe out the old different fluid from your vehicle’s drive-train.

A 75W-90 will be thinner at higher oil temperatures than a 75W-140. Both are the same thickness at lower oil temperatures. The 75W-140 is said to have a wider viscosity range – when more accurately it would be a wider temperature range.

Which is better 75W90 or 80W90?

Ans: 75W90 is artificial and mostly better than 80W90, but it costs more. 75W90 has a better low-temperature viscosity and is good to run all over. If you’re in a warmer zone, using 75w90 will be more suitable than 80w90 for you.

Which is better 75W90 or 75W140?

Is 75W140 better than 75W90?

I think you’ve got your numbers backwards the 75W140 is the heavier (140 vs 90) and for more severe service. It is recommended only for the rear diff and only for heavy towing and continuous use. You shouldn’t go heavier than 75W90 in the front and for normal duty and occasional towing 75W90 is fine for the rear.

How much does it cost to change the rear differential fluid?

Keep in mind that when changing the differential fluid, the overall differential fluid change cost averages between $80-$150 for the rear and $70 to $130 for the front change, coming in at a total price of between $150-$280 for the differential fluid change cost.

How do I know if I have a limited slip differential?

The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.
