Changed oil in 250 hp merc runs good doesn't smoke as much.
Works great in Mercury motors. Very good quality oil
I have used Triax synthetic oil in a Powerstroke diesel for years with great results. Now I will use it it in my outbound motor
Yamaha 150 SHO requires 4.5 quarts for center of dipstick. I put in 5 quarts which is one container. Price is comparable to Valvoline but you only get 4 quarts. Free shipping and tax included. Great value.
Excellent oil for any outboard 4 stroke. My 115 pro xs purrs like butter with this oil. Forget sub-par dino oil the manufacturers recommend. Get this high quality synthetic and don't look back.
Ditch the factory brand, and substitute this for your modern Mercury outboard. I serviced mine at 5, 50 and now 100 hrs with this product and it drains clean. All TRIAX products are top tier.
