This stuff is well worth it. Noticed the first oil change that my truck runs smoother and quieter(Toyota tick). Waiting to see the oil analysis when it's time.

I have been useing amsoil for over 25 years I have zero problems with it I run it in every thing I have

I have been running amsoil For over a year now. Naturally aspirated v6 in a 2011 Ford Explorer and TwinTurbo V6 ford F150. We know how turbo charged engines can generate heat and breakdown oils much quicker I really like the extended drain intervals and even with almost 13,000 miles on my F150 the oil that came out was still very thick. probably could've gone several thousand miles more. Usually with that kind of mileage and that kind of abuse oil comes out the consistency of water. I'm not easy on my vehicles either And tow from time to time. I just purchased oil, transmission oil, and filter for my Honda TRX 450 Atv. You have a customer for life!!

I use. the product in my daily driver has improved gas mileage

This company is #1 for oil and have a lot more products the oils I use work well I have taken motors apart in past and they are clean and no damage good products

I run everything amsoil even snowblower I own a boat a Jeep Wrangler Chevy Silverado rmz450 dirt bike a hayabusa and other small engine equipment all motors run perfect nothing better enough said!

Ever since being introduced to Amsoil, it's all I use. I've put it toe-to-toe with friends using other brands of oil, and they've eventually seen the light and moved over to using Amsoil as well. Never disappoints.

I'm currently using your 5W-20 synthetic motor oil in a 2008 Toyota FJ Cruiser. Startability in sub-zero weather has been excellent.I've also noticed an increase in gas mileage, which is a definite plus. The engine runs quieter and smoother than it did with conventional motor oils. I will continue using Amsoil products until I'm no longer able!

Bought a brand new 2017 Ford Explorer (NA 3.5L). After a couple thousand miles, I changed the oil over to Amsoil Signature Series, using Amsoil's filter as well. I've been changing the oil based on the in-dash oil life counter which gets to right about 10,000 miles for servicing. All has been working just fine so far at 25k.

I put it in my vehicles and change it when needed

Amsoil is Great. I've used it for 20 years. It's in everything I own. Why would you use any other oil?

Some of the best oil I have ever used. I tow a 10k lb trailer and oil temps even in dead of summer stay very low. Would definitely recommend to anyone.

I buy this product once a year along with the oil filter. I have a car that is 16 years old and it runs great. Have always used this oil and filters.

The only reason I'm not giving it 5 stars is because I have a 2002 Nissan pathfinder with 240,000 miles leaks a lil oil but with Amsoil 5w-30 signature series and when I use it it leaks even more...think about your high mileage customer. I aslo have a Infiniti QX56 2008 with 132,000 with 5zw-30 signature Series no leaks at all and just did the transmission fluid ATF, transfer case and front a rear diff with the server gear fluid and shifts are so smooth rides like a dream 5 stars on that! But for my 02 Pathfinder had to switch back to a conventional high mileage oil with seal conditioner.

Have used AMSOIL for 2003 SVT Focus and 2011 Saab 9 3. Focus has 336,000 miles and Saab has 115,000.

I use this in my 2001 f150. I currently am at 246,000 miles and it is still a strong motor and have not broke down this motor yet for internal work or repairs.

Love the protection and convenience of 1 oil change a year.

I use this oil in all my vehicles. It works day in and day out

When you have some get in the truck & ask why it runs so well it opens the door

Works better don't burn as fast in my truck that eat gas and oil as snacks
