Been using for last 5 years. Stopped my old engine from knocking, and went from using oil to not using when I switched to Amsoil.

I used your oil more than 15 years, now my car run like BRAND NEW (My car Is Honda Accord 2008). Thank you.

2017 Taco TRD offroad 4x4. I have just over 2500 miles on this oil now and have seen real MPG gains, granted very slight ( just over 1 MPG gain). My truck definitely runs better too.

As long as Amsoil continues to win the comparison tests against the competition, I will continue to purchase this product. The pressure is on Amsoil!

I put this in my wife's Audi and my Range Rover sport better engine protection and best oil you can buy.

I initially ordered the transmission fluid and accidentally got the engine oil. After returning the engine oil and receiving transmission fluid signature series, I must say how pleased I am. I noticed the few MPG improvement after changing the transmission fluid which had 43K on it. The engine shifts through the gears more smoothly.

I have a 2010 minivan that used 1/2 qt. per 1000 mil. after using 5w-20 signature series motor oil it now uses none "this is the good stuff!"

Keep my car in Tip top shape.

my truck has 256000 mile run like new

Great oil, everything advertised is accurate!

I use the oil and filters in my muscle cars and truck. The click everyone complains about went away in the motors .Easy startup on the motors and no dry lifter sounds.

I use all Ams in all my toys and cars! You get what you pay for. This is the best.

When trying to go the full 8000km between oild changes typical synthetics do seem the break down around 6000km, You can tell but the return of valvetrain chatter even faintly after startup. I've noticed the Signature series holds up and I no longer hear that return as the miles / km's increase. Great Product!

The title says it all been buying for a long time for multiple different vehicles never fails

Seems good....engine hasn't blown yet.

Greatest point is that I only need to replace the oil once per year as I only put on approximately 25-30,000 kms per year.

Look at any proper sheer test and this wins. The only oil I'll trust in my boosted built engines!

Had a slight tapping noise coming from my engine, after a oil change and new filter will AMSoil the sound was almost unheard, after a few hundred miles the engine is purring like a kitten : )

Best in the business

My Honda CRV runs great on this oil. My mileage has increase and it just runs smoother. I highly recommend this oil. The best in the business.
