Customer Ratings & Reviews

I only use Amsoil in all my vehicles. Amsoil extends my oil change intervals and improves my engine performance. I'm well pleased with how this oil performs against conventional oil that I used in the past.

Car runs strong and smooth

Been using this oil for 12 years.

I put 100 miles a day on my daily driver. I purchased it with 40,000 miles on the odometer now it has 84,000 miles on it. 4 qts go in, 4 qts come out.

I love all Amsoil products very satisfied a longer duration before changing oil ever 6 to 7 thousand better than every 3000, with conventional oil.

Eliminates rough idle and extended change intervals beyond what a typical customer expects. I get great feedback from my customer base and it saves them money while protecting their engines with premium product.

Use it in all 3 of my Dodge vehicles. Outstanding value.

From my work vehicles to my play vehicles I use Amsoil in them all for peace of mind

How can we spend so much for our vehicles and not want to take the best care of them we can? I've used AMSOIL's lubricants in every vehicle I've owned for many years, and have always felt I was taking the best care of them I could. The 5w20 Signature Series I use in my 2013 Dodge Durango has given me so much peace of mind. Why would I want to use anything else?

I use it in my 392 hemi and love how it keeps the hemi smooth as butter

Use it on my 1995 Chevrolet Camaro z28

I only use Amsoil in everything i own .

Have 303,327 miles on the 03 honda civic,and still get 38 MPG.No smoke out the tailpipe,and still change the oil at 25,000 miles.Signature Series oil works for me ,the proof is the civic,not snake oil.

Really like it!

your car was expensive don't scrimp on the oil amsoil oil and filters

It's the only choice I make for my truck. Only down side is that not many local stores carry amsoil so to buy a top up litre is hard to find. I just buy one extra.

One vehicle I have is a 1988 Bronco II 2.9 engine 5speed. I have all Amsoil lubricants installed in it. THE ENGINE REALLY LOVES THE 5W30 Signature series oil.The Amsoil fluids really make a difference.Thanks Paul
