Customer Ratings & Reviews

Been using the 75/140 for 5 years on a 1998 Dodge Ram 2500 towing pretty heavy with zero issues, which is the goal of any good lube!

Love the squeeze pack, no more pumping for me! Has better protection then stock Toyota and flows easier at same the temperature, can't go wrong with "Severe Gear" I'm going to start towing a Travel Trailer and having a higher max temp was a must for me.

My mechanic was happy with me providing him with this product for my truck. He even liked the packaging. My Armada is running great since it's been used will purchase again.

My Goldwing is a lot smoother using this S.G. oil. I change it at every oil change since I can do it while my engine oil drains.

Also is the best gear oil for heavy loads and extended change intervals. If I service it later around 30k I will see how dark it changes color. OE fluid was dark but it had 113k on it. will keep an eye on it at next oil and filter change.

Easy to use pack

Used at 40,000 MI and now at 90,000 MI in front and rear differentials. Mostly City and highway driving not really towing but they run great

Use in my motorcycle and at every change no metallic comes out and fluid looks almost as clean as new at every 5k service worth every penny and service here is awesome

I don't usually like what the manufacture suggests because they want you back in there to replace worn items. I like using this product with the slip lock additive and it keeps my differentials working nicely.

It seems to be a fine product. I like the package. It’s easy to use in tight spots. It appears to be good quality.

It seems to be a fine product. I like the package. It’s easy to use in tight spots. Very clear looking oil.

This is great packaging ,saved a great amount of time filling rear differential. Oh and the oil is as usual the best to use !!!!!!

Needed gear oil for a rototiller. 75w-140 was specified by the OEM. Amsoil Severe Gear Oil is a perfect fit and the easy pack made adding gear oil to the transfer case a snap.

Every car and or truck I buy I immediately change all of the fluids on it. No mater how many miles are on them I start with a clean service plate. Rear differential front differential transfer case everything gets amsoil including my engines.

Anything made by these folks is top notch.

Did a full ams oil fluid change wow what a difference.

Should’ve done this change as soon as I got my vehicle. Now at 250,000 mile on my 2003 Silverado,it is still a big improvement.

Bought Severe gear oil 75w-140 for ptu fluid change. The car feels smoother after the change. Please give a big raise to whoever design/package the oil in squeezable container. It helps a lot when filling the unit in tight space without need of hand fluid pump!! Wish there are more local retailers that carry the product so I do not have to deal with shipping and waiting.

Looks good, will see how it looks next service. Shipping was quick!!!

Had a chatter in rear end, changed the gear oil with severe gear along with slip lock . Chatter is totally gone. Truck has 270000 miles on it and now runs smooth.
