Customer Ratings & Reviews

I drive a 2018 v6 camaro. I completed an oil change at 42,000 miles with your oil including your filter. I drive approximately 160 miles M-F. At 19,100 miles chech oil warning light came on and it was 2 quarts low. I don't know how expensive oil can just burn up that fast. I know you will probably respond with I should check my engine oil level regularly which I normally do when I use Castrol oil but when you have 25,000 mile expensive oil I guess I became complacent. As of this email I did an oil with your oil and filter and I will definitely monitor the level.

Amsoil signature series oil is the very best oil you can get hands down!...it truly is an oil that you can have in your vehicle for 25000km. I don't do it myself but I wouldn't hesitate or be worried if I had toake it serve my to engine that long. Amsoil is the creator of synthetic oil and are by far the best advanced oil you can get. It will cost a little more but when it comes to your vehicle(s) you want the best for your investment. I highly recommend them, I use amsoil in both cars and my truck, including my 2 stroke race bike and all my small engine devices too. It puts me at ease to know that all my engines are using amsoil products. Research them and you will see that they are far by the best! Cheers!

Every time I have my car serviced the mechanic comments on how the engine condition is excellent

I have not used yet!

Best oil by far testing and reviews say it all watch project farm oil championship...

My log splitter runs better with this oil.

I switched from the Polaris razor oil to the amsoil I get a lot less speckles in my oil and oil change it's definitely cleaner and the motor is 100% quieter

2019 POWER WAGON 6.4 HEMI, IT IS MUCH QUITER WITH THIS OIL THAN THE RECOMMENDED PENZOIL ULTRA PLATNUM 0-40 SYNTHETIC, I WILL NEVER USE ANYTHING ELSE FROM NOW ON.

Been using AMSOIL oil and products for years. Never a problem. When they came out with their own oil filter, I use only theirs. My Hyundai Elantra, 2013, just keeps humming along. Would not use any other products.

My Toyota Corolla is older than some people who will read this, but it's probably healthier thanks to Signature Series. She runs as smoothly as a sewing machine, even on 30F-below mornings, and still gets nearly 40 mpg in the summer (35 mpg in the winter). Plus, I love the convenience of changing oil once a year.

Just started this oil I’m hoping good things will come out of it.

My Nissan Frontier is getting close to 400 000 km and have been using Amsoil synthetic oil since i was over 200 000 km...also rear diff, transmission, transfer case, and front diff all amsoil synthetic oils..not sure truck would still be running if i hadn't switched to Amsoil lubricants...engine not burning oil at all, runs like a sewing machine!

I find the amsoil 5W30 engine oil to be superior to all oils I've used in the past. I have been a synthetic oil fan since 1980 and I've tried so many different brands. I keep coming back to amsoil, and now I'm convinced that it's the very best that money can buy. I sell 5W30 oil to all my family members who need that need that weight for their engines. They save gas and the engine stays clean. It's worth the extra expense.

I have use this oil exclusively on my 2013 Lexus GS 350. It is the best oil I've ever used. I found this oil as a step above the standard recommended oil from Lexus. It stays cleaner longer and allows for extended oil drain. I still change it at 10,000 miles or less because of the protection it provides. I know it's a little bit more expensive than the standard oil but my car now has 169,000 mi on it, and still running strong.

Been using Mobil 1 for years... did the engine flush and switch to this Amsoil Signature Series. Immediately I noticed a much smoother reving of the engine. It take almost nothing to get up to speed. Can't wait to change the other fluids as well. 100% Amsoil all around!

It’s the best

My wife 2019 Ranger has a 4cyl with a turbo. At 50,000 miles it has been flawless and I want to keep it that way. I change the oil and an Amsoil filter every 10,000 miles and the oil has been better than expected after 10,000 miles every time. These small engines rev higher and with the turbo I feel most confident with Amsoil oil and Amsoil filters that it has the ultimate protection.

Simply the Best

Best oil on the market! You really can feel the difference when you put oil between your fingertips. I trust this oil enough to run it for a year time frame in the car before changing it.

I have used this in all my autombiles for years. I change my oil every year and have not had any problems. The last car I traded had 180,000 miles on it and to my knowledge is still running.
