Regular use, nothing extreem. My vehicle did have slight idle issue, possibly from gasoline impurities. After switching to Amsoil and oil filter it runs completely smooth and purrs like a kitten.

Works really good gave me better mileage

I always use Amsoil in my cars I race....never had a problem , been using it now for 8 years, five different cars !

Simply the best oil on the market. Only oil I use on my 2014 GT 500 with over 1k rwhp

Have used Amsoil Signature Series for a decade now. Last oil report stated the engine at 76000 miles is "ageing like a fine wine". Also use the 2 cycle oil & it's great!

Great customer service

I invested in a Lexus LX570 that should go a half million miles. The best oil available is a small investment to keep this rig going for a few decades

I have an 08 Harley Heritage Softail twin cam with over 52,000 miles on it. One of tbe biggest issues with these motors are the cam chain tensioner, which wear out and can cause catastrophic engine failure. I opened her up at 50,000 and the tensioners look brand new!! Also run Amsoil in my 99 silverado 4×4 throughout ,engine ,trans,transfer case and both differentials this one just turned over 200,000

I use nothing but Amsoil motor oil in all my cars!

I used to drive a Porsche and the shifting was sticking. i replaced the gear oil with amsoil and it shifted like cutting thru butter.

With Amsoil, I am saving time not waiting at the dealership, not paying them to change my oil, not worrying if my oil cap is tight; now I'm changing it myself every 10,000 miles, gaining 3-5 MPG, and, if I catch the deal, it's delivered to my house for free. All pros, no cons.

I drive 100 miles a day to and from work in a 2011 Chevy Cruze ECO 6sp manual and run Amsoil SS 5W-30 and Wix filters, I have sent this oil off for samples and can safely run 18K intervals with a filter change half way between. This oil is wonderful for the engine and turbo.

I put 200 miles a day on my truck. conventional oils require me to take down time to change to often. with this product I swap out the oil with way less frequency. saving time and money. And my engins run great till 200-250,000 miles. it is a great product .

Use this in my Subaru XV. Engine runs great, and Blackstone says it works. Happily run this for the extra piece of mind.

This is a great oil. It runs amazing in mu 2008 WRX. Wouldn't use anything else in it.

Wonderful product. Im never going back to conventional oil. I feel like an idiot for using it for as long as i did. Bottome line, better fuel efficiency, longer gas mileage, it feels like my engine glides with this oil. Do it!

Run in my mowers great product

Works great

Use this oil on a Lincoln hybrid. The car is very sensitive to changes. The drive being the same day in day out. Changing to this oil improved fuel economy by 1.5 mpg. Engine runs smoother also.

I have been using 0W-30 Amsoil Signature Series since about 36,000 mlies on my 2007 F150 along with Amsoil oil filter. 281,000 miles and still running great. Excellent power and good fuel mileage. Of course I also do the other routine maintenance as well. People can't believe how quite it runs and still has good power. Amsoil is fantastic.. Engine still good and tight, no oil leaks!
