My 2.6L 2017 Mazda 3 engine idled much more quietly after the oil change. Amsoil Signature Series 02-20 replaced Mazda Service's 0W-20 that had gone 15k < 1yr. Engine is working great. Highly recommend Amsoil. (My oil filter is now an Amsoil).

Have been using amsoil in my 07 liberty since 2009. 260k miles later with no engine issues and still running great.

This is the only oil I use in my 2010 bmw 335i my car has upgraded turbo’s and it’s producing close to 500 hp at the rear wheels. I have noticed the engine runs smoother and quieter, and when I do oil changes 3K in this car, the oil is much cleaner than the last oil I was using. It is a little more expensive but it’s well worth it along with all the products that they sell..highly recommended!!!

Very good product keeps the engine running great

Use to run Motul in my 2003 Subaru WRX for years. Bought a 2018 Subaru Type RA and continued the Motul. Local inventory was running low so I tried Amsoil Signature Series. I still had enough Motul for 2 oil changes so I ran the Amsoil for 3,000 miles then Motul for 3,000. Took several months of back and forth with lab results every oil change and the results proved Amsoil did slightly better than what I previously thought was the best. Wear metals down slightly and overall viscosity was higher! And this was through the hard running summer months when I run Tail of the Dragon every weekend. For those not familiar it's 318 turns in 11 miles and way harder on the car than any track day. Nice to know I'm now protecting both my Soobies with the very best...lab proven! Thanks Amsoil!!

I drive 1000 miles a week, so I rack up a lot of miles on my cars. I put 300,000 miles on my last car with the original engine and transmission. Nothing but Amsoil for me!

I have been using Signature 5w30 EAO17 filters since 2013. Very satisfied

I’ve been using Amsoil for quite some time. I’ve used it in my Harleys now in my Nissan Sentra. I can’t say enough good about this type of oil. Great job guys.

Amsoil is my go to oil...

No doubt, the best engine oil you can buy to protect your engine. I use it on many different vehicles. I never worry about extended drains.

These are superior oils! I wouldn’t use anything else.

I use it in all my cars and Pwc

Used in 2004 Ford Expedition..wife runs about 7k a year...once a year oil changes...210k on truck...no oil burning, gas mileage is same as new

This is my new favorite winter oil for my Tacoma and rav4. Better cold starts than 5w30

Only use this oil in my 23 Shelby f150 truck. Best oil on the market for performance and reliability!

I grew up hearing my grandpa sing the praises of AMSOIL. Now it's my turn. We bought a 2016 RAV4 and started using AMSOIL. The result? This is the first car I've ever owned that doesn't burn or use oil between changes. The engine runs as well as the day we bought the car. What's more, I only change the oil every 15k miles instead of every 7500 miles. Win win.

I use this in all my Vehicles and families vehicles I say the price is high But what more a case of this oil are a new engine? I say the oil price is much cheaper. Buy it try it you'll see the difference in performance.

Can't buy I better all around product. Also run/ran the small engine Amsoil in my mower and dirt bikes

This oil might be more expensive to store brands but, you know where that money is going. I've had this oil tested after 5k intervals and the report came back saying the integrity was like new. I don't trust 10k change intervals, this oil I believe can stand up to that, as advertised. I've pulled the top end my engine and there's no varnishing. Just a clean engine!
