1 pint of TC-W3 water craft rated oil (wall mart sporting goods section...pennzoil) to 6 gallons of regular gas.

Look at the top of this page and get into the Boat Parts and Accessories section where you will find Seloc Brand manuals. I have used their online subscription and used a Merc. OEM at the same time and liked the Seloc better. You can rent time and have the manual instantly, or buy a paper copy and wait for it to arrive.
