Just did the first 100 hr service on my new Yamaha VF90. Manual called for 90 but this 75w-90 is all that’s offered from Amsoil. Hopefully it’ll be fine.

Using this product in our out boards has been great We have inspected our gears sets and found them in superb condition Just to clarify my out boat is twenty years old and has only eve had this oil in it My boat goes3-5 times per week and more with weather permitting

Been using this oil for years in my outboard and it performs excellent, also got rid of a clunk inhad when going to reverse/forward. Highly recommended this for any marine applications

using this in my Suzuki gives peace of mind

Great product

work great fast service

Good product

I have used Amsoil products for as long as I can remember. You will not find a better product on the market period.

Shipment arrived quickly and as always quality product, and piece of mind knowing my boats operating at peak performance with amsoil

used this lube every fall to replace oil in foot on my outboard have never had a problem

Works as should. A brand I trust in.

Got a brand new outboard wanted the best

I have been using Amsoil for 10 years . It works well in Polaris Rangers.

Fantastic gear lube for all my outboard needs

Above and beyond expectations

Easy to service the lower unit

I just noticed that the consistency and color of this grease has changed. Can someone contact me and let me know if the formulation has changed??

As always great customer service and awesome oil , I have been using amsoil for over 10 years in my truck , all my outboard engines and Grease for my trailers, outstanding product definitely recommend using Amsoil . Even Though they forgot my free telescoping parts wand that I still have not received.

I have found less foam than OEM Oil Amsoil oil is a better product

Drive unit had a rough shift into forward and reverse. Since changing lower unit gear oil to Amsoil, everything shifts more smoothly.
