I use 4 ounces of oil to a gallon in my engines, can I use that same mixture in my Quickdraw?
If 4 ounces is working good in your other engines, you should stick with it in them. But in the Quickdraw you will get your best performance at 10 ounces to the gallon. I have run our engine on 6 ounces and it lost .2 HP. I then ran it on 4 ounces and it lost .3 HP. These dyno runs didn’t show any accelerated wear but then they were reasonably short runs but from many hours of on the water testing by a lot of different customers, I can honestly tell you that there is a major increase in the life of the engine on 10 ounces. Again, I am referring to the Quickdraw. We used to recommend 4 ounces to the gallon, and with enough testing and time it increased gradually up to the 10 ounce mark. I have ran more oil than this and power will start to drop off if I go any further than 10. We recommend Honda HP2 oil. There is no doubt other oils may work just as well but that would take testing, and a lot of it, to find them. We have seen hundreds of engines back here for work over the years with ma
