I have been using Amsoil motor oil, transmission fluid, and filters on my cars since I owned them. One is a 20 year old Honda CRV and the other is a 10 year old civic. I change the oil once a year and replace some of the transmission fluid (about 3 liters) once a year. No problems with these vehicles.

I've been using Amsoil since back in the 70's and it's literally the only oil I use. Early this year I bought my wife and myself nes Kia's and did the vert first oil change when I got them home!

Great product, have been running this oil for over 10 years now engine problems. 2022 Toyota Tundra supposed to have bad engine mine still running after 44000 miles on Amsoil 0-20 xl.

I've been using Amsoil Extended Life Oil for about 5 or 6 years and it has performed flawlessly for me. I have a 2015 F150 with only 30K miles on it. While that might seem like no real test for an oil, it's actually worse on an engine to drive it short distances and not warming it up sufficiently than it is to drive it many miles per day. Many times I start my vehicle, pull it out of my garage and shut it down to use the garage as a shop. All this contributes to oil dilution and acid formation, etc. For that reason my oil changes are usually made every 6 months with close attention to the dilution of the oil and the lubricity of the oil. Before using Amsoil XL I used to pay close attention to the oil to determine if I should do more frequent oil changes. After using Amsoil I noticed that the dilution has been almost negligable. With other oils I saw a rise in the oil level after afew miles and about 90 days of stop/start driving and I would have to change oil. With Amsoil there is no such dilution. I run the oil for 6 months and change it with no detrimental affects. Great oil.

Use this stuff a lot and has been great

This is a great choice for oil in vehicles and other meachines. Great value with the best protection around!

I couldn't be happier with the oil and filter performance. I'm an every 5000 mile guy and when i drain this stuff at that mark it feels wasteful still in almost perfect condition. AMSOIL guy for life

I have used this oil for 2 and a half years, in my 13 Taco and my 15 Highlander. From the magazines I have read incredible reviews for long lasting protection. In my oilfield job I beleive it reduces friction and heat. I change oil every 5000 miles and filter. But the color I drain looks brand new!! I am very satisfied. There are manly youtube videos out there saying the same thing. Great product.

I have been using Amsoil products in all of my vehicles for the last 20 years or so and after logging hundreds of thousands of kilometers on several different vehicles with no oil consumption between extended oil change intervals and no apparent engine wear I can confirm from my own experience that Amsoil products provide superior and lasting protection.

My 2020 Outback hit 25k miles, so I went to the AMSOIL. I don’t drive it everyday, but seems to run a little better. I’m sure it’ll be good for the turbo as well!

Been using Amsoil since early 2000's. This extended life has been great and quieted down my 2001 GMC with 290K on it.

This is the first time I have tried this oil, but I'm sure it will be great. I just thought my 2007 Gmc with 18000+ miles on it might need this for it's seals, even though nothing is leaking yet.

I’ve been using Amsoil now for about 4 years and would NEVER use anything else.

This oil is the best oil on the market. Been using it for several years.

I have used the extended life oil and my engine has been running perfectly with OVR 60,000 miles

I got my parents running this oil in their ‘06 Colorado as they don’t have a turbo or need everything the signature offers. This is still a fantastic oil and they have had great success with the extreme cold we experience up here -40 to -50 degrees celcius plugged in cold starts. I’ve left a bottle of this outside overnight and poured it out in -38 c no problem.

fast shipping and for free, quality oil and price is very good

I drive about 40k miles a year and i need an oil i can trust as well as products to clean my engine. The XL line of oil is my goto oil

i have 3 vehicles and several gas powered outdoor tools use Amsoil in all of them.
