Best overall oil for any vehicle, engine starts and runs smoother especially my 5.3 LS, no more tick!

Since changing from Mobil1 to Amsoil years ago, i no longer have to "top up" my oil level between oil changes. Not to mention the money I save with the extended drain intervals.

I love using amsoil, it is the best oil I have come across. One of my vehicles, 2003 nissan 350z, the motor (VQ35DE) is known for burning oil. With amsoil, very little burns compared to other brands like mobil 1 and valvoline.

Use it regularly. Oil still looks clean every time I drain it

I have used Amsoil for many years and swear by it...bar-none, the best on the market!

Overall great oil. However, I wish it can in 5qt jugs. That it pretty nitpicky though.

Great product use it on all my toys I wish it was 5 quarts instead of four this would make an oil change similar

Can’t beat amsoil. Just wish it was sold locally

My 2025 forester takes 4.6 quarts of this super thin oil, my only complaint is that I can not get it in a 5 quart bottle.

I use Amsoil Signature Series in all my vehicles and I believe it is why they are all well over 100k miles and one is over 300k and still running strong. Best fluids out there in my opinion.

We just bought a new Lincoln Aviator with a 3.0 twin turbo. I've always been told AMSOIL is the best. I did it's first oil change at 2400 miles with a WIX filter. I plan on an interval of 5-7 thousand miles depending on my cross country trips. So, I guess we'll just have to wait and see how it goes.

I have used your oil for several years with no issues. With the chaos in the oil markets and the collapse of the Fram parent company thru financial criminality I am glad that I still use it.

I run this on my 23 camry every 5k miles and have had zero issues and no sludge build up. she is sitting at just shy of 50k miles now and i plan to keep using amsoil for as long as i own the car

Amsoil products are all that I will use

Great oil, I believe it's great for my high mileage Lexus GX470.

Best oil in my opinion....after changing amsoil transmission oil ...my Tundra shifting better than factory

Been using this oil on my 2020 tundra since 25k now at 137,000. 2013 jeep compass and 2025 jeep compass. I have not had a single car or truck run better on anything else noise or performance wise.

I only use this oil none else

Math works Preferred customer works Oil works

My 2023 Sierra 6.2 used to knock on start up and now its super smooth. I also get better MPG vs the old full synthetic I used to run. A++
