One great oil to go the distance like 10,000 miles on one oil change like I did if you are pushed to deadline oil change at 3,000 mile you can skip one two, or three changes I would recommend change it after 10,000 miles no worrys just drive on

I decided if I was to do extended oil changes for my vehicles that synthetic is the way to go. All my research says that XL is the best. My engine runs smooth, it starts easy in the middle of winter at -20 below. With a $30,000 vehicle why not take care of it with the best. As a preferred customer I think the price is reasonable.

I am 71 years old in my second childhood. I have used every kind of oil in my life time. I personally will never use any other oil in my special car other than AMS. I bought a 2013 SI Honda Civic and I put a supercharger, different exhaust and had it dyno tuned and much more. Results over 300 HP to the wheel. I fell safe using this oil up to 6000 miles but I change at 30% not 15%. If you use this oil in your car you will never change to any other. I guarantee that.

I have used Amsoil for years, with zero failures related to lubrication in any of the vehicles, I have "amsoiled" Built three LS motors with this as the break in, and beyond. Drove these motors HARD and when doing some upgrades on one we were all amazed that the internals looked as they had when built and the micrometer showed nearly unreadable wear after 30K of performance driving. Just bought a 65K Tahoe with all the toys, the first thing done, tinted windows and full amsoil change out, Oil, diff's, trans, PS, you name it... done.. Why... because I have a known quality product in place of what I'm sure was just fine factory fluids BUT... It is done with something I know and trust, simple as that.

I have used many brands of oil in my Rava 4, Amsoil has out did them all, best fuel mileage.

I used XL 10-30 in my 1982 Toyota P'up with 22R engine. She ran smoother, cooler & quieter. Used Amsoil in transmission & differential. Still running strong @ 344,000 miles!

Works as described...used in my 5.7 hemi and 3.6 in wifes journey both 12000km intervels... No problems

Nice long lasting oil, keeps engine running clean.

I have used XL 5W-30 motor oil in two vehicles for the last six years. Very happy with performance and wear. I would recommend this oil to everyone.

I am satisfied with the results so far in using amsoil and how well it holds up to extreme duty driving.

I have a turbo charged 4 cylinder Chevy which tends to run hot. I use Amsoil because the science says superior engine protection under high heat conditions. With 136,000 miles in 3.5 years have had no problems. I will keep using Amsoil.

I've used Amsoil products sense the 70's and they never fail to deliver. I have never had a oil related engine problem. Plus when everybody compares themselves to a product then which do you buy?

I have always used synthetics in my motors and never miss a beat when it comes to maintenance. I recently started racing RallyX with my wife and I have heard great things about Amsoil so I thought we would give it a try. I had no idea what we were missing out on. Basically it took the motors efficiency and turned it up to 11. Just changing to Amsoil from one race we were able to push our 88' Mazda 323 motor into a top 5 finish against cars as new as 2016. I now use Amsoil in all my cars and buy oil by the case.

This is the best product on the market

I use Amsoil in all my personal vehicles, and the results do add up. I can tell the difference right away. Pleased to be a Amsoil member.

5-6k mi changes and zero burn/ consumption 140 k miles and strong . Still clear at 5k change.

This oil has never let me down. I always average two miles per gallon better over other leading synthetic oils. Perfect oil for longer intervals and reduces O.C. issues. Great work again AMSoil.

I use Amsoil in all my vehicles-- from a 34 Ford to a new Equinox. Just sold a 97 accord with 300,000 miles on amsoil and engine was still like new. I also convert all to other amsoil fluids early in their life. Never had a failure of any component using amsoil.

I was introduced to this product (won a case)in the late 70s as a door prizes at a golf tournament. I got away from it until I bought my 2000 F150 when I worked with sone one who was a representative. It is the best product. I also put it in my wife's 1992 Toyota. When I had it (Toyota) torn down the shop couldn't believe how clean it was internally. I have not had my F150 worked on internally because it is still great with over 247,000 miles. It is worth the money and effort to use and change your own oil with Amsoil.

The best oil I've used in my lifetime!!!!
