    Been using Amzoil since 1977. Presently have a 2009 Camry Hybrid with 197K miles. Runs great--averages about 40mpg on highway and no oil consumption. Great oil!!!

    Better gas mileage and longer time on oil changes
    By  Roy,  a  Verified Buyer  on  October 14, 2019
    The best motor oil you can by hands down. Check out the oil analysis on-line. I went 19k miles on my Prius and oil analysis said that I could go on up to 22k without any issues. This was and independent oil lab.

    Amsoil the top rated oil by experts who know!
    By  Sam,  a  Verified Buyer  on  October 12, 2019
    Been "my own" mechanic and all about repairman all my life. Did much of my own maintenance and repair work on mine ... and families automobiles for years. Since being disabled in 2008 with medical conditions that limit me now to very little physical work, I looked for the best lubrication I could find. After much research and even with help from qualified "lubrication expert chemical engineer" I knew from my work days , I confirmed there is no better quality lubrication than Amsoil products. I use the Amsoil motor oil for two reasons. #1 It is the best motor oil on the planet - hands down with intense research to verify. #2 I use it because in my physical condition and being unable to change my own oil like I used to , I use the Amsoil because of its long lasting quality that allows me to confidently go with long intervals between changes.

    Best synthetic oil, period!
    By  ELIS,  a  Verified Buyer  on  October 08, 2019
    I have tried many products in my lifetime trying to protect my investments from friction damage. I purchased a new 2002 1500 Chevy Suburban LS with a 5.3 liter engine and tow package. Was using a competitors synthetic oil and was very satisfied with the product. All the ticks and clicks that bother me were gone and the smooth running engine was great. The problem with the oil was that it was hard to come by locally and when it could be found it was very expensive and the wrong viscosity. I had to resort to ordering on line in five gallon containers and found that the oil was burning off about one quart every 15,000 miles due to heat. Specs. on the product indicated it could handle the heat but apparently it could not. An offer for an AMZOIL Preferred Customer came to me via e-mail so took advantage of the offer and ordered oil filter. Changed oil and filter using your products, started the vehicle and did not notice any difference but the more I drove the smoother the engine became. I could not believe the difference, so since then I only purchase AMZOIL products and will never put another product in any of my vehicles. AMZOIL is the best!
