Customer Ratings & Reviews

I have bought other brand synthetic oil but when use in my truck weekly I need to add oil. When I started using Amsoil signature oil in truck did not use one drop of oil. This is the best oil out there to buy

Seems to be one of the best out there. I own a 2019 Ram 2500 with the 6.4 HEMI motor. There are a lot of discussions and complaints out there reguarding valve noise with this motor. I have used this oil since my first change at 2500 miles and don't have any valve noise or complaints.

My truck loves this oil! It runs so good with it!!

Just knowing that I'm running the best motor oil (AMSOIL Full Synthetic 5W-30) in my 287 c.i. engine, gives me joy and great piece of mind.

This oil meets and exceeds your expectations of quality. Owning a turbo car as you know oil get hot especially in the summer months , My car filled with Amsoil never seen oil temps higher than 200 degrees vs the competition oil that seen 220 degrees + with the same daily driving habits and route. The competition oil cooked and caked up on my dipstick when I did my oil change switching back to amsoil never once did Amsoil break down . I highly recommend this oil .

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
