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.

I have tahoe and Silverado both with 3.0 durmax diesel only oil I will use

Running amsoil in every thing including outboard

I switched both cars to the same viscosity so I can order this in gallon jugs. Very good oil and I'm saving money, I'm way smarter than I look.

I've used this product since the very 1st oil change on my 2004 Ram 1500 and it's by far the best product I have ever used when it comes to motor oil and life time of your engine.

Really happy with the service and delivery from AMSOIL, I’ll be a long term consumer.

time will tell how good it may be

Been around for long time because amsoil is the best

Best oil ever prompt delivery
