I have a q50 and want to baby them turbos so this oil is the only way to go

As a kia owner I’m aware of how sensitive to preventive maintenance these engines are after 55k miles zero issues no oil consumption with 3K mile oil changes.the best oil in the market

Amazing product will never go back to other synthetic products. Thanks

👍🏻

Outstanding oil

This oil is the real deal. Warm weather performance fantastic, cold weather performance, just as good if not better. I have been having some engine issues since switching to Royal P's race oil, one with high Zinc additives. Terrible, cold or warm, decided to switch to this after doing some research... What a night and day difference it made, truck (5.6L engine for ref.) runs smoother than it ever had!

I did the research and have been using the oil ever since. I will never go back to fake synthetic oils again.

Always got what I ordered in a reasonable time frame. Never had an engine go bad using AMS Oil.

excellent quality and long lasting oil for turbo engines (corolla GR)

Amsoil Signature Series is the best oil on the market. That’s all I use in 5 cars within the family going back to a 2005 Ford Crown Victoria. I don’t use anything else.

I don’t drive a lot of miles, I change my oil every 6 months and never worry about it!

Only oil I use in my wife's Equinox four cylinder turbo charged engine! Great for the turbo charger!

Only oil I use...best for my 4 cylinder turbo charged engine in every way!

I have put this in my Tahoe and so far I'm quite happy with it. Amsoil in all my vehicles

Best oil on the market in my opinion. I take oil samples and have them analyzed every oil change. Wear metals are down. I change my oil every 5 K miles, No matter what. I don’t trust going over that dew to evidence that sludge will start building up going over that mileage with any manufacturers oil

Ce qu'il as de meilleur sur le marché actuellement , moteur propre , puissance dégagé , le meilleur !!!!

Love this oil and how my truck runs on it!

The price of cars make me want to have them last and operate trouble free. Start with excellent oil and filters for your best results. Amsoil is as good as it gets for daily drivers.

First time changing oil with this product and it was below zero in early January. Mileage increased, even using winter fuel.

Finally someone makes top of the line synthetic 0w-16!!
