Customer Ratings & Reviews

I own several motorcycles and use this product in the final drive and transmission. have a combined 75,000 miles with no issues

Off roading demand that U change oil often

Use in my tranny and Qick change round track asphalt car.

Since 2005 I've been a dedicated user of Amsoil products in all of our autos and high performance BMW motorcycles (S1000RR and K1600GT). Never have I had any issues using these products.

Put it in the rear end of my 68 gto. Great great product.!

175,000 trouble free heavy haul miles. The new gear oil pouch makes it so easy so change diff fluid. Make the switch to Amsoil today. Proven protection in the worst conditions.

Ive been running this in both axles for 112,000 miles. I dont have issues with kicking it in 4WD in extreme cold (no 4WD button/knob in this rig). The rear locking Eaton differential works reliably with zero noise. I tow consistently and I tap shift 97% of the time I drive to avoid using my service brakes which puts extreme stress on my drivetrain (bought truck new, truck has 125K hard miles, original factory installed rotors & pads are still on it and only the pads have worn by 2mm max). I drain & fill the diffs every 45K and I only get metal dust at the plugs, no flakes. So, I would say its working well.

Great

I've used these products for well over 25 years and recommend them to my friends. Nothing but Amsoil, from bumper to bumper in my vehicles.

Love it. Ashley Carte was great help.

I use it in all my dmax trucks

I put this in my 2001 legacy gt and shifting felt awesome. Well I got a 2013 WRX and of course changing all fluids to Ams-oil and shifting since switching to it has been buttery smooth. I couldn't be happier.

I do not use any other gear lubricant in my vehicle. I trust Amsoil Severe Gear to keep my vehicles running top notch, no matter what I put them through.

I use this gear oil In my jeep and in my tow vehicle works great

I use Severe Gear lubricant in my 2016 Harley Street Glide's gearbox. It immediately shifted smoother and it's easier to find neutral. Plus it quiets the first gear clunk to some extent.

I have used this in my side by side, truck and absolutely notice an improvement in the smoothness and lower noise levels with this gear lube. Highly recommended.

Amsoil is really good using it for years

I purchased a 2007 HD Ultra Classic in Nov. 2006. It was the first year of the 96 cu. in. Engine and 6 speed transmission. In the first 600 miles I was bothered by hard shifting, and a noisy 6th gear. I found out Harley had used their 20W-50 oil in the trans. At 600 miles I replaced the transmission oil with Amsoil Sever Gear 75W-90. Problem solved. My bike now has 60K miles and the trans shifts beautifully with no noise.

Use in the rear end of my 40' diesel pusher. The test prove it is the BEST.

Ive been using amsoil for years in my bikes. As soon as I buy a new bike amsoil goes in it. Holds up to heat and the beating I put it through. Also quiets the trans and can find neutral a lot more easier. The only downside is its clear. Makes it difficult to see on dipstick.
