Best money can buy I never worry about running my boat hard or thermo break down I’ve been using AMSOIL in all my vehicles for years

Outstanding product part of a 18 item purchase including (2) gallon jugs. Shipping box used was horrible. Large box split along (2) of the long seams. Amsoil use a heavier than 32 lb crush box next time.

Have owned my boat with Honda BF90 outboard since 2004. Every year I change the main oil and gear lube with AMSOIL. Have not had any mechanical issues ever and the engine has been in the shop only three times in twenty-one years for tune-ups. Only use AMSOIL products in everthing I own.

Great oil and great for protection especially for my wave runner that runs at high RPMs all day.

I've been running AMSOIL 10-40 marine engine oil in my Honda Aquatrax 1200 turbo's for over 10 years now. This stuff comes out looking so good that a mechanic buddy of mine will re-use it in some of his old beater cars... it hasn't failed him or me ever!

Great oil. No problems with any of my motor since I started using amsoil 25 years ago. Capt.Ray

Running the Amsoil/Wix combination in both of my Suzuki 250ss's. Great products and fast shipment for me, and an upgrade from the semi synthetic oil that the Ecstar is.

This oil made my outboard run smoother!

I’ve been using this synthetic oil in my F115 Yamaha for years. My engine has been trouble free, averaging 95 engine hours per season!

most expensive oil in the world best oil in the world

most expensive oil in the world best oil in the world use it in my 75hp Yamaha since it was new in 2003

My Mercury 25 hp four stroke has a strict diet! And AMSOIL is what it craves!

Mercury outboard oils are a blend which I do not like. Prefer 100% synthetic for my engines.

I HAVE CHANGED ALL OF MY FLUIDS OVER TO AMSOIL. THE BOAT ENGINE SEEMS TO FIRE UP QUICKER AND RUN MORE SMOOTHLY WITH THE AMSOIL MARINE 10-40. MANY FELLOW BIG MOTOR PEOPLE I KNOW STILL USE 20-50 OR STRAIGHT 50 IN THE HEAT ON LAKE MOHAVE AND HAVASU, BUT I HAVE FOUND IM STILL CONSISTENTLY AT 50 PSI OIL PRESSURE AT OPERATING TEMP AND AM HAPPY WITH THAT

I have been using Amsoil for years in our cars with never a problem, so I’m now using it in my pontoon four stroke outboard great product!

Excellent oil characteristics that prolong engine life during hot summer months and cold winter storage. love this oil.

I have run this oil in my 4 stroke Suzuki DF50 outboard since I took the break in oil out. This motor gets run HARD either running wide open up the Missouri River or idling for long periods in no wake areas and this oil shows no signs of giving up between 100hr service intervals. The inside of this motor is spotless and I don’t worry about corrosion even during longer term storage.

My Yamaha F115 outboard runs smoothly and efficiently. Been using this oil for the last 5 years, highly recommended!

I've been using this oil in my 75hp Yamaha for 10 Plus years I'm a charter boat for fishing which means I depend on my motor running at peak performance This motor idles for 2-6 hours per trip. I inspect my spark plugs regularly and have never had an issue with fouling plugs. when i go to full throttle she never lets me down. I change its oil once a year and like what I see.

Great oil as always. However, got a new motor this year and the look up guide sucks. Hasn’t been changed in years. Just refer to your owners manual for correct application.
