Customer Ratings & Reviews

Just perform first oil change on civic si turbo. Installed signature series. Plan on getting oil analysis at next change to compare to factory oil and see if AMSOIL is worth the premium price. I will update review.

Best oil I’ve used

I started using this when I purchased a used 2016 Ford F150 in 2018, to drive back and forth to Dallas daily. I averaged 100 miles a day. I am shocked how great the oil looks when I change it after 9-12 months (varies due to schedule).

I bought a Hyundai Veloster N with the performance package and wanted to run the best oil out there. I did some research and landed on Amsoil’s 0w30 signature series. I drained the original oil at 600 miles and put in the Amsoil. I did notice immediately the oil temp stays lower until I start pushing the Turbo hard. So far so good with no issues. After the research I did I feel totally confident with my decision to run Amsoil. Only bummer is I didn’t get a sticker for the back window.

As advertised , engine is running smooth as glass. 2004 Toyota Corolla S and 2011 Ford Ranger Sport

As advertised , engine is running smooth as glass in my 2011 Santa Fe

You can expect nothing less from ams oil. I use the signature series in all our work vehicles due to the large quantity of miles they get driven a year. The superior performance and extended change intervals make it a no brainer.

I have used Amsoil since 2012 and I haven’t went back to any other brands since then. The extra cost is for added protection and ease of mind vs mobile one.

After rebuilding my engine in my G8 I switched to Amsoil after the 5000 mile break. It seems to run smoother and quieter. I used Amsol in my Subaru WRX and I’ve always had great results with it.

Use in my SUV good oil for small engines with turbo charging

Always of the highest quality. I highly recommend this oil.

The only oil I've run in my last two cars. Both of them performed great with this oil.

Get oil engine runs great and valves are quiet after 130000 miles

I am not a chemist or a scientist but in my short experience using the product, I believe that this product is the best I am going to get! I have 2 more vehicles to switch over to Amsoil products.

Great product! 100k miles on a 3.5L Ford. My TBN number is 2.5 with 15k miles between oil changes and no oil added.
