The transmission shifts smooth.

I replaced my rear diff 2011 Challenger with 2015+ diff added the 75w-90 plus the LSD additive its smooth and quiet

Only gear oil I use if it is the recommended weight for that vehicle. Great stuff.

Felt the difference and my old fluid wasn't even that old. Ford recommends 150k miles for rear diff. Fluid was dumped once at 30k for a diff cover replacement and replaced with OEM Motorcraft synthetic 75w90. I did it again 40k miles later and replaced with Severe Gear 75w90 and felt an immediate difference in smoothness and maybe 0.3 - 0.5 mpg improvement. I didn't expect do feel anything but was blown away that although it wasn't drastic, it was still noticeable.

I’ve got a 2008 GMC Duramax diesel dully and developed a problem in the differential. The locking mechanism started to hang up. I suspected that the clutch plate ramp cam was not releasing the way it should. My truck is very low mileage for an 2008 (33K) but has done some pretty heavy trailer hauling. I was afraid that it might blow when on dry pavement. I drained the old GM grape juice and poured in Amsoil sever gear lube (75-90) and I have not experienced any lockup for a couple months now. Fixed what could have been an expensive repair bill. Thanks AMSOIL!!!! Gary

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.
