  • On another note, what is the best gear oil for a manual transmission?

    Red Line's GL-4 transmission lubricant is our top pick for your manual car (just make sure it meets your specs). The formulation is less slippery and low in sulfur, which makes it compatible with brass synchronizers, and it meets the requirements of 70W, 75W, 80W, SAE 30, 5W30, and 10W30 motor oil.

    So anyway, what is 75w90 gear oil used for? Product Description. Mobil Synthetic Gear Oil 75W-90 is a fully synthetic gear lubricant formulated from synthetic base oils and an advanced additive system. It is designed for use in many railway gearboxes and provides excellent load-carrying capability where extreme pressures and shock loading are expected.

    Any way, is it OK to use 75w90 instead of 75w85?

    Our answer: Yes, 75W-85 gear oil can most definitely be replaced by 75W-90.

    Can I use 80w 90 instead of 75w90?

    If you have differential whine that is quieted by a thicker fluid, then 80W-90 might be a good option. It will certainly be thicker than 75W-90 for most owners' operating conditions in moderate climates. You could also try 75W-110 for a thicker oil that performs better in the winter.

    11 More Questions Answered

    Is synthetic gear oil better?

    There is no argument in the lubrication profession over this question; synthetic gear oil is overwhelmingly superior in every category measured. Large trucking companies, like UPS for instance, use nothing but synthetic gear oil for better fuel economy and to extend equipment life.

    What is the difference between 75w90 and 80w90 gear oil?

    SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It's thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90. The use of 75W-90 gear oil is recognized by OEMs as a contributor to overall fuel economy.

    Is gear oil and manual transmission fluid the same?

    The most obvious answer to this question is that gear oil is generally intended for use in manual gear boxes and transmission fluid is for automatic transmissions.

    Is Thicker gear oil better?

    As a general rule high viscosity oils are best for low speed, loaded gears with a rough surface. Higher viscosity provides a thicker film, higher wear resistance, and less deformation of the gears as time goes on. Low viscosity oils, on the other hand, are best for high speed systems with lower load.

    Is 75w140 better than 75w90?

    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.

    Can I use SAE 90 instead of 75w90?

    Yes. 75w-90 should be just fine.

    Can I use 75w90 instead of 75w140?

    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.

    What kind of fluid goes in rear differential?

    Every front or rear axle is filled with a special oil (also called differential fluid, or gear oil) that takes care of this. The differential fluid lubricates the gears, bearings and other internal parts, and provides cooling to these components as well.

    What does 75w90 mean?

    The 75W90 is a high performance multi-purpose 100% SYNTHETIC GEAR OIL with ANTI- FRICTION TREATMENT. The 75W90 is formulated with PAO synthetic base oils and the highest quality additives.

    Is 80w 90 the same as SAE 90?

    SAE 90 is a very large scale. 80W-90 is the low end of the scale, while 85W-90 is the high end of the scale. Both are single grade SAE 90 oils. SAE 75W-90, is more appropriate in most climates where 90 is specified, specially if it is a transmission.

    Is SAE 80 the same as 80w 90?

    For many climates, the SAE 80W-90 is a good viscosity for the Corvair, but as you saw in the viscosity graphs, it is much more viscous than the original recommendation of SAE 80. There are products available that cover that full range with a SAE 75W-90 rating, or even a 75W-85.
