Customer Ratings & Reviews

I've been using this product for several years now, and since I don't drive more than 10,000 - 12,000 miles a year, I only have to do an oil change once a year. Of course I do use the recommended oil filter with this oil in order to do that.

I've had other full synthetic oils that didn't clean an oil pressure sensor. After switching to this Amsoil 5w30 boosted. I haven't had any issues with my oil pressure sensor at all.

88000 miles no problems

Best oils on the market!!! Amsoil never dissappoints!

I use Amsoil 0w20 & 5w30 XL Boost in my 4th & 5th Gen 4runners. Engines runs smoother than any other oils I've used and gives me great confidence for the longevity of my vehicles and their performance. For gear oil, I use Amsoil 75w90 in both vehicles front & rear diffs as well as transfer case. Highly recommend all Amsoil products for Toyota 4runner needs.

Switched to Amsoil several oil changes ago for my daily drivers. Engines are quieter with more power. More than worth any difference in price since I keep my cars well into the six figures on the odometer.

Great products always with the best quality!

Great oil.

Best top quality. Not over priced like oem dealer oil. And shipped to my door!!! Which is priceless

After watching some independent testing I switched to Amsoil for my 2018 WRX. Using this oil let's me worry less about engine reliability so I can focus on enjoying my car as it was intended to be driven.

been using marine Amsoil for 30+ years, now have either XL 10W-40 or HD diesel in 6 different vehicles , 3 w/over 100k miles. 71 Jeepster actually started using less oil! May be my imagination, but all 6 seem to crank quicker, run smoother than before!!

Great product

Have been using this oil along with the amsoil oil filter iBall my vehicles for over 20 years wouldn't use anything else

For many years I'm using Amsoil and I've make some of my customers believers in the quality and money saving Amsoil products.

I just put the 10w-40 Amsoil in my 2013 Toyota 4Runner with 167500 miles on her, I use Purolator filters on my oil changes. As soon as I cranked up the engine I could tell the valves were more quiet at idle through acceleration on an interstate on-ramp. I highly recommend this oil throughout the year. This engine is running smoother now vs. Mobil 1 synthetic. No comparison!

I have used AMSOIL products in my cars for almost 20 years and have never had an oil related repair. I will always depend on the most dependable lubricant for all my vehicles.

Again I would never put any thing but Amsoil in my Vehicles. That would be my Harley, F150, Z4 BMW and wifes(charlotte) BMW.

All my important engines will always drink Amsoil. Excellent products!

Best thing to ever put in my engine

Great oil only oil I use.
