Been using AMSOIL for 20 years be nice to get a free oil change

Honestly for the longest time thought amsoil was a bit of a marketing gimmick but when I swapped from mobile 1 high mileage on my tired turbocharged k20 with 225,000 miles it started to burn less oil and the engine just felt smoother I’m impressed by it surprisingly.

Great product

I've owned a Honda S2000 for 15 years now. Used Mobil 1 Synthetic for much of its life...switched over to Amsoil Signature and I'm never going back. My engine sounds better on this at 7,500 mi than on Mobil 1 at 500 mi. It's like my engine is swimming in hot butter...highly recommended!!

Our vehicles oil cooler line bursted and ran the oil out of our car. Drove the vehicle for about 10 miles not knowing this happened. Got home and heard some ticking under the hood and checked the oil stick and there wasn’t any shown on the dip stick! Shows me that Amsoil oil leaves a protective film in the motor. I do believe in Amsoil! Saved me thousands . I use Amsoil in everything that has a motor. Thank you for a GREAT PRODUCT!

Have been using this oil in Ford and Asian vehicles for years and have had zero issues with it !

Use Signature 0W30 over 5W30 for greater engine protection , engine runs cooler , better fuel economy and way better for catalytic converters ! Also the 0w30 prevents low speed pre-ignition , another plus ! I am an automotive repair shop owner and my shop uses this oil in all of our newer GM cars and light pickups , except the 0W16 models !

My car now has 200,000 miles and I have never used anything other than Amsoil. Runs like it is brand new. I think it will last another 100,000.

Great product but shipping company used is terrible. Will stop using Amsoil if they continue to use UPS. Products arrived again with oil and filters all over my drive way. UPS is notorious for destroying the shipping boxes. I know, as I worked at UPS. Terrible shipping company.

I decided to use Amsoil for the 1st time and I am 100% satisfied with the results. My car seemed to run a lot smoother and and is making the car run fantastic! Believe the hype! I am Nee to using Amsoil, and would recommend to anyone. I’ll update in the future to see if I still feel the same, but as of now, it’s worth the money to spend if you want to keep your vehicle for duration, and maintain it well. Love this oil!

I have been using Amsoil Signature Series Oil in all my vehicles and motorcycles for past 3 years. Quality and longevity of oil is excellent.

Just what I needed for my older truck '07 Nissan Titan. Thanks!

Very good oil.

I use Amsoil in everything i own

This oil plays a crucial part in protecting my high revving (9000 rpm shifts) engine. The oil also stay cleaner than the other oils I've used in the past. I am very confident in this oil!

I have been using Amsoil for 20 plus years. In my book it's the best oil on the market. I use it in everything I own. has not failed me yet.

I keep forgetting to change the oil in my wife’s 2017 Subaru Outback. I am glad I have Amsoil Signature Series oil in the car. Unsurpassed protection even when left in for extended periods.....
