The only thing I like about using synthetic oil is after 50,000 miles or so, the inside of the engine looks brand new, no sludge or oil contaminant color.

Mr. Awais

For the best synthetic oil and lubes look to Amsoil, it the best for the value.

Malik Nisar

The product is exceptional for wear and tear on engine components. Quiets down a noisy motor and helps to cool it efficiently.

I've used this for my last few oil changes on my '04 Corolla, and I've noticed that my engine feels decidedly more smooth as it runs, and when I drain the oil it's color has not degraded nearly as much as other oils I've used.
