Great product fast shipping!

My 2017 WRX, (not STI), rund like new and I've used Amsoil Signature Series since 10,000 miles. I have 68000 miles now and while I change the oil every 3000 miles due to modifications, 368 WHP measured on the Mustang dyno, it never misses a beat. Sure, it's expensive, but so are all the other boutique oils out there such as Motul, which by the way gets beat hands down by Amsoil in independent testing. There just isn't another oil with the proof to back up the claims like Amsoil, is there? If so, please do tell!

Best oil ever that I’ve used in my Genesis.

Always run Amzoil

Have used AMSOIL products for over 30 years.Would not use anything else. Use in trucks to incude diesel,cars,small equipment, 2 cycle engines and other types of equipment with great sucess.

The product is 2nd to none

Changed my wife's oil in her 2018 civic sedan with the 2.0l ...ruff idle and the engine vibration would rattle the dash....changed the oil with amsoil and it runs way smoother and no vibrations whatsoever

I’ve used Amsoil in my Silverado for two years now and all the hype about amsoil products has held true for me. We have drastic temperature swings from sub-zero winters to 80-110° summers. My truck gets mild- heavy use and after a years use I was a little low on the dipstick but the viscosity was still good and the filter still working well. Not to mention My oil used to get changed three times a year@ $70 a pop, I’m not change my own once a year at about $115-$120 a year so I’m saving money.

I think this is one of the best oils I have ever used. I'll tell you why. I'm busy so, having a longer life means I change oil once a year and feel confident. Also, it's save gas. MPG is better than with other oils. Those are my main reasons for sticking with this brand. Over 50 of me changing my own oil, I can tell this is quailty.

This is an awsome product!!! In have been using this oil in my vehicles since the mid 70's !!!!

I use all amsoil products! From chainsaws to Atv to all my vehicles and have had great success with each!

Best oil ever

I am a repeated customer of this oil, and I have only had a great experience with it. I only change my oil once a year, and my car runs very well. I am very happy with this product.

Been using Amsoil for years and never had an oil related problem including leaks.

I don’t write very many reviews but this product is so good I had to let people know about my experience with Amsoil. first of all I’ve worked on cars and car audio systems for years and I’ve always used Valvoline because that’s what my dad used on his cars. I bought a brand new Challenger in 2019 and noticed it idled kinda of rough it’s a V8 and has a loud exhaust but I know cars and I could tell over the exhaust noise something wasn’t right. I thought maybe it has a bad spark plug or two or maybe a bad coil but I dismissed that because of the low mileage around 400 miles in 2019 I changed out the oil to Royal Purple at like 1,200 miles and nothing car still idled rough. I changed it again at like 2,400 miles same purple oil and nothing so recently I switched to Amsoil Signature series after watching a YouTube video and the response from my engine was immediate the rough idle went away instantly!! I was shocked and amazed the car has 4,000 miles on it and it idles like it now thanks to Amsoil.

Love this oil - been using it for years in my 4 Subaru Foresters

I love the 25K Signature Series oil specifically bc I drive a lot of miles daily and it certainly saves me from having to change the oil more often. I’ve been using Amsoil for years now and have had ZERO issues with my 2008 Dodge Ram 1500 with 245,000 miles on. It. Coincidence? I don’t know, but I sure trust Amsoil and contribute the lack of maintenance on good Amsoil oil. I trust it 100% and for the price, well worth it!

For the first 50,000 miles I used another Synthetic oil and Just wasn’t pleased. I have used Amsoil for the subsequent 205,000 miles. I am very happy with the product and intend to keep the motor unopened for the next 250,000 miles I needlessly worried about using this oil with the Chrysler Hemi Multi Displacement System. I needn’t have worried as this oil allows my Hemi to perform optimally. One of the nice things is that I have never gotten less than 20mpg on a fillup. Try this in your hemi.

Only oil I use in my 2014 Mustang. Tons of track time and abuse to the motor and she still feels strong. My only gripe is that it takes nearly 12qts & I'm sick of having individual quarts - pouring one by one and dumping the old oil in one by one.... Amsoil really needs to make a jug size option for this weight of oil.

extends oil change to 1 time a year , well worth it
