Love this oil! The engine runs noticeably smoother. Other oils give that "Hemi tick" when they break down and with the one year or 25k mileage on this, that tick has never again been heard! The only oil I will run in my SRT8 6.1, PERIOD!

You can’t go wrong with Amsoil products I’ve been running them in everything I own for 20 years

probably the best engine oil I have ever used. Started putting it in my 2006 Lincoln Mark LT when new and it has 150,000 miles with no issues . My son used this in his Roush Stage 3 Ford f-150 and also no issues as of 80,000. Great Stuff.

Being used in a 09 F150 5.4L since it was new. The engine has 340,000 km & has never had a wrench on it.

I only use Amsoil in my turbocharged vehicles. Not only does it protect my engine but it's super important to protect the turbo end shafts during running and after shutdown. If oil burns on the turbo shafts after shutdown you'll be changing turbos soon.

Purchased a high mileage Chevy with the 5.3 liter V8 equipped with Advanced fuel Management. It had a few valve ticks in valves, but being it was clean truck I would take a chance. I changed the oil and installed the signature series 5W-30 synthetic. Within a few days the ticking stopped. I again changed the oil & filter, and so far the engine is quiet and smooth. The Best Oil I have ever used in 40 years!

Keeping my F150 alive, 230k and still rolling. Oil is the life blood of any engine. Amsoil is by far the BEST!

This pours in just like regular oil !

Been using this oil for years. It out performs all others.

well above average

I have used this product for over 13 years now and it has proven to be one of the best oils on the market. I got 287000 miles on my Sierra using it. It is now in all of my vehicles

The one oil I have used for 20 years.

Use this in all my vehicles. Great value! Good Performance!

It's my first use of amsoil so far so good

Started using Amsoil in my 2005 Honda Goldwing, it made such a improvement in shifting I never went back to the Honda oil. I recommend it to everyone. Now using it in my truck an motorhome.

Been using the Signature Series Oil now for about 4 - 5 years now. With the price of new cars now days, I want a motor oil for my 2011 Honda CRV to protect my engine in all sorts of climates and I believe the Signature Series Oil does that for me. I use mostly all their oil products in all my engines. 2 cycle and 4 cycle. Protect what you have and it will last longer. The extra price is worth it. Oil filters are great also.

Absolutely love your product and absolutely love your service. I make an order and I always get it within a day or two. Well worth the money! Won’t ever use anything else!

I had an older toyota truck with lots of timing chain tensioner noise, changed oil and put in amsoil synthetic, no more noise, rally lubricates well, tried other synthetics but just dint work as well.

Love this oil for the convenience and how it protects my vehicles. Amazed at how clean it stays before getting dark. I do not think it ever turns black.

i rebuild engines, i use amsoil after break in period for my personal vehicles, hemi engine, super charged grand prix to my Audi turbo charged engine
