Customer Ratings & Reviews

Love Amzoil. Worth every penny. I wouldn't run anything other than amsoil in my vehicles. Top of the line product.

Lowered transmission pan, changed filter, and replaced drained fluid w AMSOIL ULV. 10R80 shifts like brand new, especially down-shifting on hill decline - super smooth. Highly recommend.

Great product and really does well in my ram 1500

Night and day difference from other oils I have switched all my oils now over to AMSOIL

AMSOIL products are great the shipping is bit to be desired almost 3 weeks

2019 f150 5.0 10R80 transmission. Drain and fill with OEM replacement filter and filter seal. Replaced plastic factory pan with PPE standard depth pan. Collected all fluid that was drained including trans cooler. ( collected 9 quarts) Was able to replace approximately 9.75 quarts for proper fluid level @ 210 degrees F. Cleared transmission adaptive tables utilizing Autel tool. Performed drive cycle relearn procedure as close as I could. Have been driving truck in Tow haul mode in stop and go traffic and in Normal mode on highway. Unbelievable difference in transmission performance. Transmission operates better than new.

Have been using Amsoil motor oil for years in both of my h/d cycles. And as far as I can see it is doing great. First time in 94 gmc 4L60E I will let you know

Did a 30k interval drain and fill when I noticed some performance degradation on the quality of shifting. Noticed gear change improvement afterwards. Will continue to monitor performance before the next change interval.

Amsoil I that i can trust everytime.

Works great

👍

Have used oil filters for my 2019 Duramax in the past. Time to service my transmission and rear differential so I upgraded both to the Banks Ram Air pan and cover. Decided to also upgrade the fluids and the temp levels are noticeably lower.

2016 GMC Yukon Denali 8 speed Had a very bad transmission shudder. Completed a transmission service using this fluid. Shudder is gone.

Just replaced all the transmission fluid plus the transfer case

Second amsoil fluid change on my 19 1500 boosted hemi, this time a deep pan took 10qts vs 6 for OE pan.

Great as always

Changed transmission fluid in my F150 Powerboost at 39k and immediately noticed smoother shifting and slightly better fuel economy. The truck is also going into electric mode a little more and staying in electric mode a little longer. Don’t wait too long to do yours.

Great product, easy and convenient to use. Love it. Fast delivery

Great product Amsoil is all I trust in all my vehicles in all applications. These quart bags are a godsend trying to fill front, rear diffs, transfer cases and transmission on my GMC Sierra. Made the job so much easier and no mess or waste.

Just had my transmission serviced with new filter, new aluminum pan, and Amsoil ULV fluid. Already notice smoother shifting. Hoping this helps prevent some of the inherent problems with the Ford 10R80 transmissions. Time will tell.
