Works great in my old sea doos and priced fairly!

Injector Oil is Outstanding

I have been using Injector Oil in all my hi performance outboards since 2000. Most notably on my Evinrude outboard hi performance ETec engines. I noticed that whenever I changed oil to another brand, it would not take long to build up a sludgy deposit in the exhaust at the propeller. Using Injector oil cleaned this deposit out fairly quickly and I never noticed any smoke coming from any of the engines when using it.
