    Good stuff
    By  JERRY,  a  Verified Buyer  from  Ky  on  January 23, 2025
    I've been useing this stuff for 6yrs now and in that time I've had 3 cars with well, 1 320k 1 460k & 1,200k. It's great oil and I've been doing 10k oil changes for oil to last like that it must be good. But I use there oil & matching filters. Had a Ford edge with 200k was sounding rough on start up, like a lawnmower when I 1st got it and oil pressure light was coming on changed oil with amsoil & filter and my wife's been driving it for months now and hums like a sowing machine now nice & quite. Also use it in my pride & joy my dad's old 73 Pontiac firebird formula with the original poncho moter in it. Great oil and is no higher than what's on the shelf when u set up your own account and so much better oil.....if u want to hit 400+k use this oil....

    Amsoil very good products
    By  DAVID,  a  Verified Buyer  from  Ohio  on  January 17, 2025
    I have been using amsoil products without fail on multiple vehicles over many years. One vehicle has 300 k miles and runs like new. Regular oil changes is key. I highly recommend amsoil products without fail- David northern Ohio

    Good Results
    By  ROBERT C,  a  Verified Buyer  from  Quincy IL  on  January 14, 2025
    Actually never used your product. Bought a car and the owner uses your products. They swore by it. So watching one of favorite YouTube person, and just out of coincidence he was featuring your product in a test and your product ranked the best. So I’m a customer of your company now. 😊
    Bottom Line
    Yes, I would recommend this to a friend.

    Review
    By  ERIC,  a  Verified Buyer  on  January 10, 2025
    I'm super excited ! I've been using your great products for several years , and I purchased a used 2011 Toyota Tacoma 4wd double cab in all stock configurations, with less than 50,000 miles , this truck has a 4.0 V-6 5 speed automatic, and before changes I was getting 18 mpg , I recently changed fluids in the differentials , transfer case , engine , and flush the radiator, heater core , and block used the heavy duty 50/50 mix along with using all Amsoil synthetics , and installing new spark plugs and air filters , , with no modifications to stock running gear , and in the bitter cold temps , snow and ice in Southern Indiana, this truck has seen an increase of 3 mpg , so fantastic work , on making an excellent product , that is far superior in lubrication properties , allowing this vehicle to move more freely, Thank You !

    Worth the upgrade
    By  DARYL,  a  Verified Buyer  from  SC  on  January 09, 2025
    I had been running the OE full synthetic for years and thinking the signature series wasn’t worth the upgrade. Man was I wrong.. My 1997 f150 had been running 5w20 OE for years. Occasionally on cold mornings would tick for a minute or so on start up. This drove me nuts since I had done a basic overhaul of the entire engine. Complete with new Melling tappets, chain tensioners, chains and Ford oil pump. In a nutshell the only thing I didn’t do was remove the pistons. The cylinder walls looked great so I figured send it. That turned out to be a bad decision. I didn’t want to buy new pistons and rings and pay for machine work. I decided to make a switch to signature series in my most recent oil change and the tick seems to have resolved itself. Thanks AMSOIL
