Customer Ratings & Reviews

Great products and oil filter.

Works good

This is the absolute best oil available for my 2007 Mercedes-Benz C230 Sport. I drive about 18000 miles per year, and I change my oil 1 time per year. This oil is well worth the money!

Been using Amsoil for many years great customer service and fast delivery

I have used this oil since day one on two brand new Toyotas, 2020 Highlander,2021 Tundra. Excellent cold starts

Started using this oil and I can honestly say it runs cleaner and the oil pressure stays consistent throughout the entire time between oil changes. My oil level is also remaining the same with little too no loss at all.

Awesome in my 6.2L Silverado

Perfect oil for my 08 LS 460

I’ve used this oil in my ‘04 mustang cobra for years .I also use the same stuff in my ‘02 Ford F-250 and my wife’s ‘18 Ford Rapter.I just like knowing I have the best oil money can buy,hands down.The ‘02 F-250 has over 120,000 miles on it and runs great. I’ll keep using this oil from now on.

I can wait longer between oil changes which saves me time!

One of the most important aspects of this product which switched me over from another synthetic oil competitor is the volatility rating. I had experienced oil loss previously, but I know with the regular oil changes that I do and verifying the PCV system was not obstructed, I landed on the problem of volatility. With some lesser quality synthetics it can result in oil evaporation. My vehicle has a number of miles on it, but the amount of oil loss, and the duration of time it happens within, was considerably, and significantly different when I switched to Amsoil.

After 2 oil changes motor just purs, operation is quieter and acceleration is smooth powerful and not as noisy on RPM revs. Invest in your cars/trucks engine life longevity and get your case of 5W30 Signature today!!

I'm happy with my purchase. It's the ONLY oil I use. I just wish I could get free shipping. Being that I'm a member. it should be part of the perk

I have been using AMSOIL in all of my Lexus and previous vehicles for years. Based on my research and due diligence of the company and it’s products, I am totally confident my engines are in the best shape ever and will last for many years to come. Guys keep up the awesome work and creating excellent products.

With Amsoil there is NO HEMI TICK. Proper lubrication makes my cars purr. 0-40 in the 6.2 Hellcat and 6.4 Scatpack. 10-40 in the Old School 440.

I purchased 0-20W Full Synthetic Signature from AMSOIL for my wife’s 2019 Honda CRV 1.5L Turbo. I’m hoping it will surpass any other Full Synthetic Motor Oil on the Open Market, Including Castro , Mobil 1 and The OEM Dealership Oil Honda Uses. It poured out of the Bottle Quite Clear in Comparison to Any Other Brand I have Utilized AND I have Used A Lot of Different Brands For Longevity, Reliability As Well As Noticeable Fuel Savings considering Today’s Fuel Costs (08/20/2022. So far it’s Still Very Clear on The Dipstick. I Used a Mobil 1 Long Life/ Protection Guarantee Oil Filter with it from Walmart. Extra Fuel Economy has not been noted. Engine runs Great on it though. Only Time will Tell the True Benefits

I thing your product is the best on the market I knew someone years ago that told me about he used it in his car great oil

I have been an AmsOil customer since pre 2014. A Jeep Dealer Service Adviser recommended I try the 25K mile edition over the 10K I had been using for years While I don't go the full 25K miles I do change between 15 and 20K as I am a full time RV traveler and have all my Jeep service completed back at my purchasing dealer. This extended life gives me one annual oil change a year which works well for my travel schedule. This oil remains clean looking for many miles. I strongly recommend this product.

So far so good. Car runs great.

Can’t always get to doing my oil changes in time so it is nice knowing that my engine is still protected with the best oil possible.
