Customer Ratings & Reviews

This is the best oil on the market I only change my oil twice of years with this oil and I drive a lot of miles this oil has not fail me yet.

Costs more than conventional synthetic motor oil but the benefits of the higher tbn and base stocks give extra peace of mind for extending the oil interval.

A friend recommended Amsoil for use in my vehicles approximately 25 years ago and I am very satisfied with the results. Numerous oil samples taken from various cars and a pickup truck (mileage at sampling usually between 15k and 25k) convinces me that one gets what one pays for.

Great product. Highly recommended

I use AMS in my F150. First time using in my new to me Accord. Already getting 3mpg more commuting then previous oil. Its the only oil this car will get moving forward, plus i have piece of mind and changing every 10K instead of 5K

I see positive results now that I use Amsoil Synthetic 5w-30.

I've been using this oil in all of my vehicles past and present. My present truck has 149,000 km on it now but past vehicles have had 450k, 600k, and 675k before selling them. All used synthetic oil and amsoil filters.

Fast delivery , great product, buy with confidence

This engine is notorious for valve train failure between 125,000 to 150,000 miles. Personally I believe 5w-20 weight oil is the reason these engines fail. I bought my truck in 2010 with about 23,000 miles. I began using Amsoil 10W.-30w. I am approaching 240,000 miles and my engine runs like the day it was NEW. NO timing chain issues, no valve Train problems. I change THE OIL every 5000 to 7500 miles. In the South with have high summer heat and HIGH HUMIDITY. AMSOIL MAKES THE FINEST OIL MONEY CAN BUY. PERIOD. BEEN USING IT FOR ALMOST 20 YEARS NOW IN EVERY PISTON ENGINE I OWN. THEIR TWO STROKE OIL FOR OUTBOARDS IS AMAZING STUFF. MOST OIL CAHNGE PLACES WILL CHARGE U ABOUT $30 TO $35 IF U BRING UR OWN OIL. EXCEPT VALVOLINE PLACES. ON YOU TUBE THEIR IS A VIDEO WHERE THEY TEST ALL THE MAJOR BRANDS OF OIL PENNZOIL PLATINUM SMOKED MOBIL ONE IN THE WEAR TEST. THEN AMSOIL BLEW PENNZOIL AWAY WITH FAR SUPERIOR WEAR PROTECTION. THIS IS WHAT REALLY MATTERS IN KEEPING UR ENGINE RUNNING LIKE NEW .

I would recommend this oil to .y friends..

Amazing product, 10/10 recommend!

its a great synthetic oil save me about $200 a year vs monthly oil changes

My wife’s 2017 Camry went from 20.5 MPG to 23.5 right after I started using the Signature series, the oil pays for itself just if fuel costs, I recommend it to everyone!!!

Very good quality of oil and outstanding life of oil. I have been very pleased with the performance plus the home delivery is awesome. Highly recommend

I’ve been using AMSOIL since 1996. No complaints. One cat has 298,000+ miles and still going strong.

I had to replace a timing chain and camshaft actuator sprocket on my 2013 Accord, which required removing the front engine timing cover and valve cover. This engine had 75000 miles, with engine oil changed every 5000 miles. When I removed the valve cover I was shocked! There was no sludge or residue anywhere. It looked like a new engine. I use Amsoil 0W-20 Signature Series oil, and after seeing how clean this engine was, I would NEVER use any other oil. People that use Amsoil have always bragged about how good it was, and I just took it with a grain of salt until I started using it. Now I know. Can't recommend it highly enough. Expensive, but worth every penny. Get the Preferred Customer account because that will pay for itself.

My 1996 Chevy Impala, with 21,000 original miles only gets the best of everything. Amsoil Signature Series Synthetic motor oil ( remember, only the best of everything)!

This is the best motor oil in the world. I just put it in my new Atlas, and it runs even better and smoother now.. also mileage went up.

Great product & a history of proven performance
