I'm completely confident my customer will be pleased.

I run this in two high mileage Subaru, my wife's Hemi Aspen, and my 08 Hemi Ram, It has been in my Ram for over a quarter million miles. It has 315,000 on it and still running great. They all also have Amsoil trans fluid. Between the four vehicles that's 830,000 miles and all still have original motors and trans. What else needs to be said???

Good so far Can’t complain

Amsoil the best engine oil… in the world.. for me as a auto mechanic

Purchased this oil to use in my wife’s leased 2019 Lexus GX460. Up until recently we had been taking it to Lexus for maintenance which she insisted on. Now that we are using the 0W-20 signature series she wished we had been using it all along. Truck runs noticeably smoother, gas mileage has improved 2 mpg for city driving and has smoother cold starts. If you want the best, look no further. Amsoil is hands down the best oil on the market. It’s utterly apparent, the bean counters aren’t meddling with products here only concerned with profits. I will never use any other oil in my cars aside from Amsoil. No one else comes close to the quality that comes from Amsoil. .

I have done annual oil changes with this oil and Amsoil filter on a friend's 2019 Subaru Ascent the past couple years. She has nothing been great things to say about the engine running smoother and quieter than before.

Was disappointed that I could only purchase 1 tube of grease at a time. So I purchase grease (case) from a different vendor.

Great oil!!

Love the stuff have always used in while I was racing and now I have a scat pack and I won’t use nothing but the best in it

I have been using Amsoil for two year’s now and I am very pleased. I am using this Signature Series in three of my vehicles. I also am using Amsoil in 3 lawn mowers, 1 snowblower and Two Boats( 1 two stroke and 2 four stroke motors.

Every year I purchase oil and filters for 2 vehicles (Hyundai) for a year of usage. I have done this for 10+ years and I also a 70's Camaro that I also do this. In a year I may drive 7k to 15k on the Hyundia's with no problem. Before the oil & filter change on one of my hyundia's I had to change a valve cover gasket and when I looked down on the cams internal workings it looked brand new with no sludge or wear. This was at 102.025 miles. I believe in the product and have for 30+ years. You also save money in the long run!

Just bought a new camary. This oil is expensive but hopefully it will add longevity to my car been using amsoil for years. Very happy customer!

The signature series has been one of the best oils I have used. I go twice the recommended oil service so a total of 10k oil changes while changing the oil filter every 5k and its been really great. Always great products and customer service THANK YOU keep up the great work!

Made the old 5.4 in my dad's truck run noticeably smoother, before it would kinda shake at idle now I swear you could stack dimes on the valve cover. Also picked up around a 1/2 mile per gallon fuel millage wise. This is the second truck we own that I have switched over to Amsoil and I continue to be impressed. I will be switching over the other vehicles we own to Amsoil

Excellent service life. Best possible fuel economy.

175k miles still going strong!!!!!!!!!

Great product and super fast shipping.

Yes, it costs more in the short term, but in the long term, it costs much less than engine repair. Started getting interested in synthetics when I worked in a test lab for mechanical gear drives. Made at least a 10% difference then and have followed Amsoil as it has constantly improved its product.

The only oil i use in my car, when i changed over to amsoil i noticed a difference in fuel consumption and how my engine ran in general. wont go to anything else

I have a 115K miles on my Genesis G-80 3-8 and this is the only oil I have ever used in it. The result it runs silky smooth and I change it ever 10K miles. "Go for it" !!!
