Question:

I have a sport twin 10hp evinrude and wandering if i need to add any special gas additive or can i just run it on 50:1 Evinrude oil

Answer:

Hi DSK,
The 10hp Sportwins were built in one form or another up into the early 1960s (need model number to pinpoint) and don’t make the cut for 50:1 mix. They still had several bronze babbit bearings and need some extra oil to stay in operation over the long haul. 32:1 (pint oil to 4 gallons gas) using good quality TCW-3 rated oil and good quality gasoline (89 should be good enough – 87 can be kinda junky in some areas, 90+ high test not necessary) and you’ll be good to go…
