Customer Ratings & Reviews

Simply put I love this oil. I've used it in my ranger, 1971 Ariens snow blower. I will say I'd like to give 5 stars however this oil has some consumption issues. I know it takes time to work Amsoil into the engine 2-3 oil changes, however others have noticed this issue as well. My ranger was introduced at 158k ( nothing but synthetic) With this being said I'll stick with AMSOIL and see if the consumption issue I see lessons over time like the company claims. If not however I will go back to Valvoline or Mobil 1 which had the same if not a little lesson consumption for lesser price. Also my engine is spotless just did timing cover gasket and no sign of sludge.

Much better than Mobil 1

Since I used this product I'be been changing my car oil every 7000 miles and the oil is still free flowing even @ 7000.

Use for Subaru Crosstrek average fuel consumption 27mpg..now 30.2mpg!

Great product, it's a 2 hour round trip to do a oil change in my rural area. Doing it myself + the extended service miles is very welcome.

Outstanding product that I have used in my 2012 GMC Terrain V-6 since I purchased it 89,000 miles ago. I change once a year and put about 12-15 thousand miles per year on the car and the EA filter. Never any issues and NO significant oil loss each year.

Used to use other top tier oils and after hearing that Amsoil is real 100% synthetic oil and not that bogus misleading "Full Synthetic" I switched to the real 100% synthetic Signature Series 0w20, Started doing my own oil changes on my Lifted truck, found that other oils at 4K miles were literally black but Amsoil was much lighter in color proving that it takes much more abuse. Amsoil is a Super Oil

I have always used this product in my Honda Civic. My car has 168k miles on and it runs great. You will be ready for a new car before you engine wears out.

Was nervous about using thicker oil in Prius, but glad I did. With my miles getting higher, Amsoil has done wonders to my car. Going to continue using all Amsoil products for my vehicles.

I have put nothing but Amsoil in my vehicles. This is for 2018 Denali with 6.2 liter. Try to keep it running like new for years to come

Great product!

Perfect oil, great product

The best of the best

Great Oil

It's all good ! When you run with the Best you can forget about the rest

Put it n my mustang and works amazingly!

Excellent product!

I have to say its is the best I ever used, but I want to have the oil tested to what is going on in my cars engine, as I said my car is running smoother than ever I still think it beats all other oils.

I put a 5/30 in my 2016 eco diesel. It's the best oil on the market for that Ram

My engine runs quiet with this oil compared to the recommend viscosity for my vehicle oil consumption is also down ..
