    Seems to improve MPG on my daily driver
    By  ED,  a  Verified Buyer  on  November 11, 2024
    Like the title says, I’ve been using this in my daily driver…a VW Golf R that I put roughly 30k miles on per year. Since I’ve been using this on every other tank, my car has been averaging an extra 2-3 mpg versus without.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best in Class
    By  AMSOil User,  a  Verified Buyer  from  USA  on  November 11, 2024
    AMSOIL was recommended to me by family. I tried AMSOil in 1 of my vehicles and immediately noticed a performance improvement in response, idle, fuel economy, and noise reduction due to the engine having to work less to operate. Since trying AMSOil in August, I immediately signed up for their membership, moved all my vehicles lubricants over to AMSOIL, follow their maintenance schedule to spec, use their Upper Cylinder Lubricant on every fill up and exclusively use their products. Save time & Money, AMSOIL is the way to go.
    Bottom Line
    Yes, I would recommend this to a friend.

    Gas additive
    By  MICHAEL,  a  Verified Buyer  from  RGV Texas  on  November 08, 2024
    First time using this product and it does what it says. Noticed significant improvements in the first couple of miles. Sluggish acceleration went away, improved my gas mileage, and got rid of a ticking noise I thought were the rockers, turned out to be clogged fuel injectors. Great products. Customer for life!!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Continued use of great products
    By  SCOTT,  a  Verified Buyer  from  Ingram Texas  on  October 24, 2024
    I have been a long time fan of Amsoil, as I was in the racing community in the 60's -2000's running USAC several divisions and the NASCAR Modified and Super Modified divisions. I had Amsoil as a sponsor for many years of that time period. I stopped using Amsoil after racing due that it was so difficult in finding someone who sold it and would not want to sell you large quantities, if you wanted to buy if for a normal consumer need. Once I found that I a general consumer was able to purchase it from your website and become a discount customer I was all in. I did this in 2015 and have converted all my vehicles to amsoil products, I was all in. This Gasoline additive is superior to others, as I have found for one it is needed every 4K miles, not every 300 miles. I helps the emissions system cleaning, for my 2000 Toyota 4runner it has kept the catalytic converter operating as designed for over 60K miles. Additionally it has increased my fuel millage by 1 to 2 miles a gallon depending upon that amount of mountain driving I do. When doing mountain driving I find my uphill travel has more horsepower and there is no valve knocking or pinging from the engine especially when under a uphill pull at freeway speed.
    Bottom Line
    Yes, I would recommend this to a friend.

    GREAT PRODUCT BUT....
    By  ANGEL,  a  Verified Buyer  from  PENNSYLVANIA  on  October 19, 2024
    THE DEALER WHO SERVED ME ONLY SENT ME 1 BOTTLE WHEN I ORDERED 2. I SENT A MESSAGE EXPLAINING THE SITUATION, BUT THEY SAID THAT THEY SENT 2, NOT ONE. I JUST GAVE UP, I WILL KEEP BUYING FROM AMSOIL ANYWAYS, JUST ONE BAD SERVICE EXPERIENCE. THAT'S WHY ONLY 4 STARS, BUT GOOD PRODUCT.
    Bottom Line
    Yes, I would recommend this to a friend.
