I have 2 vehicles that have had this oil in them (changed every 15,000mi) since I bought them new. They both have mileage approaching 250,000, and they run like BRAND NEW. My newest vehicle is a 2017 Subie Forester Turbo so it gets Signature 5W-30 every 10,000 miles, and I'm sure it will see 200k and beyond.

It's great year round hot or cold

I have used Amsoil for 30 years and wouldn't think of using any other oil.

I use Amsoil exclusively

I have been using Amsoil for over 15 years and have never had a problem, it's a well proven product that I trust in all of my cars for work and for pleasure. I will will continue to use Amsoil and benefit from it's proven results! I own a Livery/Limo Service and I drive about 40-50K miles a year on various cars and I believe Amsoil is the best Oil for all of my vehicles. With the long 15k Mile change intervals it is a money saving gem and your engine benefits 100%. I recommend there products highly!

Used in my F150 exclusively. Excellent oil & filter. Would not use anything else.

I've used this brand and series in my Dodge Ram 4.7 v-8 since I acquired it at 90,000 miles. I've driven another 70,000 miles since and the engine is stronger than it's ever been! I expect to drive this truck until at least 300K miles because of the Amsoil Signagture Series Synthetic brand motor oil. I won't use anything else!

#1 for 3.5L ecoboost

I like being about to change oil at any time between 5-10k and not have to worry about weather or not the oil is doing it job !!!

Several years ago I switched to Amsoil in my GMC Yukon. I was very impressed with what the Signature Series 5w-30 Motor Oil looked like after the first oil change. With all the oils and products that Amsoil offers, I have since switched everything I own over to Amsoil. Even my lawnmowers.

Love that you don't have to change oil as offer as regular oil. Is is a little high. Hey but you get what you pay for.

This is the best oil money can buy in my opinion. I use this in all my vehicles and have for the last 12 years. Love only having to change the oil once a year. I highly recommend this product.

Instant satisfaction, after the first start up i could already hear and feel things running smoother.

I use Amsoil on my SUV and love it!

Always met my expectations.

I have used Amsoil products for many years in all of my vehicles and small engines. I have never had an issues. I recommend Amsoil even though it is not the cheapest but the delivery is very prompt.

Using Amsoil in all of my family's cars. Using Signature series in cars that drive over 12,000 miles per year, and XL series in cars that drive less than 12,000 miles. Sent a 27,000 mile sample for testing to a independent lab, and they recommended 30,000 miles next time based on the excellent results. Also using Amsoil in all lawn equipment and for a standby generator.

Bestboil products on the market by far. I run it in all my vehicles

Great product gives better fuel mileage and cleaner oil after changes

I've been using Amsoil since the 1980s in everything with an engine. And have bragged about it's benefits to anyone who'd listen.
