Customer Ratings & Reviews

Been using Amsoil since 1996

I have used 5w20 for many years in our f150 ford trucks and will continue for many years to come

This oil has always delivered the best protection for any engine. It keeps camshafts and other engine parts from ever having a metal to metal issue.

Best oils ever. Used for years.

This is the only non-dealer oil I can find that meets and exceeds the factory specs for my direct injected turbo gas Sorento. It has a guaranteed 25K life if you change the factory filters as per required and both my KIAs love it! So glad I found this as I have read of several turbo direct injected motors blowing up- even with a great warranty who needs that? Plus it is FULL synthetic not a blend which I will not use.

This is the best synthetic motor oil I've ever used. My 2007 Toyota Camry V6 sounded and felt smoother than before. That's what 100% synthetic Amsoil does for your vehicle. I will be putting Amsoil on my 2010 Lexus ES 350 as well. Amsoil on my vehicles only.

Its such a good product, it has done me good all these years i will be buying more in the years to come.

I use this in my racecar and it's the only oil I'll use.

Holds up very well for changing it out every 10,000 miles. No burn off like other oils.

I use to do a lot of driving . All my vehicles had 400,000 + miles on them including one Suburu with 505,000 only reason still not driving was not the engine but the rust eating the frame and body due to heavy salt used in winters .. .used the 25,000 oil change 10 -30 signature and 15,000 mi oil change filter . Changed oil and filter every 15,000 mi . Only added Extra half qt to qt at around 13,000 mi. Been a user since 1980's wouldn't use any other oil .

Sorry haven't got enough run time yet but I changed everything from mobill1 and Harley to your synthetics

2005 Honda Accord V6, was using mobile 1 extended performance oil, after an oil change there was about less a quart missing . Changed to Amsoil and waited a year or about under 20k miles to change oil and non oil were missing. Engine looked a lot cleaner as well. Improved more hp and increase mpg by a couple. Big upgrade to vehicle motors, highly recommend. Thanks Amsoil.

Best ever, been using for years and have plenty of people switching as well. Great product.

I developed an oil leak which when discovered had depleted four of six quarts of amsoil which I believe prevented some serious engine damage. I have used this product in my F-150 Edoboost since 5000 miles and The truck now has 174,000 miles. Can't say enough about this great product!

This oil is amazing I use it on my hemi 6.4 and everyone know about the hemi tick but with this oil I don't hear it at all so I love the oil I am sure the tick is still there but the noise is very low.

I'm very impressed with this oil. I thought the gas mileage might go up a little but it went up by over 3 miles per gallon. I've checked it for 4 fillups since the oil change and it actually got a little better. I will be checking it for color change and oil life. It's great so far.

Best oil on the market hands down... tests prove it and the protection speaks for itself! I wish I had switched a long time ago because it would it saved even more life on my engine. 1999 Honda Accord with 250k miles on it and it runs like new! Thanks amsoil! Well worth the extra money because you save it from having to change it once a year!

My truck runs so much better, and oil changes done once a year now.

Keeps everything running cool and smoothly. My go to..never use anything else.

My vehicle engines have lasted a long time and I get better gas mileage to boost.
