Had this tested at 5k. Results were almost the same as when new. This is good stuff!

Bar none the best oil on the market!

I've used all the commercial "synthetic" oils in numerous vehicles at my place of employment, and in my own vehicles. Amsoil Signature series by far holds up better during oil change intervals, especially in small displacement turbocharged engines. Other commercial brands become very black and deteriorated over the course of a service interval.

Yeah I've been running this oil for many years and just used it on my jeep gladiator Rubicon.

Great stuff

I use Amsoil in all my vehicles! After I do an oil change with Amsoil, the engine runs quieter, happier, and healthier! Would recommend to anyone. There is even science behind it! It tests better than other manufacturers!

I've used Amsoil in all my vehicles and never once have had an issue. 200k and climbing on my current one.

Engines run smooth and quiet. Once a year oil changes are perfect with the Signature Series. Customer service is top notch and knowledgeable if you ever need to ask questions. Email responses are always quick. Been using Amsoil in all my vehicles, motorcycles and small engines for 20 years. Noticeable difference and improvement.

Excellent advanced oils I’ve been using for years with no issues and full motor protection in muscle car performance.

What an excellent product! I always want to use the best products for my vehicles and with AMSOIL that is exactly what I got.

The best motor oil, money can buy,I ran it a full 15 months before changing it. And it was still clean.!!

AMSOIL is one of the best oils on the market. I am typically 3,000 to 5,000 mile oil changer. I do a lot of stop n go traffic. If I go a little longer between oil changes, nothing to worry about it. The longevity of the oil is there. My gas mileage seems to be a little better with AMSOIL due to the lubricity. Folks use this oil and stick with it. Your engine will last much longer.

Since I started these oil, when my uncle recommended to me. So far its one of the best oil by far and I don't have problem with it even though run my car over 5k since my last oil change. For me, I will recommend this oil to my friends and family.

Great oil

I just completed my first after warranty service and couldn't be happier with the product, service and price. this summer every thing gets the Amsoil treatment.

Best oil ever it is the best oil you can use in any motor. One se with over 250k miles

I drive my car hard and sometimes tow. I always look for the highest quality oils to use. I like to do my own maintenance on all my vehicles. I like to know exactly what oil is being used. Amsoil is my choice for my car, truck and motorcycle. The signature series is the top of the line and that's what I look for.

I use AMSOIL Synthetic Signature Series in both my diesel pick up and my little gas car. Both are older with over 250K mi. and both run quite well - smooth and plenty of power. In the Northern Rockies winter can be tough on vehicles, especially without a garage. I count on AMSOIL and it has taken good care of me and my vehicles.

Worth every penny. AMSOIL is the best way to protect your investment. I used to go 25k between oil changes. I was driving 800 - 1000 miles per week. I plan on towing a lot in the near future. Between this oil and the bypass filtration kit for my pickup, I'll never have to worry about anything lubrication-related in my engine. The 15k oil change interval will be perfect.

Nothing but the best for my two Ecoboost vehicles
