Re: what is the correct fuel mix ratio for my 1954 15hp evinrude super fastwin
Yeah its also supposed to get SAE 30 crankcase oil at that ratio, right?
30 weight oil, if marine oil is unavailable...
Let's put this into perspective...
How much does a bottle of good old TCW-3 cost?
4 dollars a quart? How much money are you saving by skimping on the RECOMENDED mix of oil?
Is that money worth the risk?
You have an engine that's been running for close to 60 years with the right blend of oil. We need to change the ratio now why? A few dollars may be saved over the course of a season?
You can experiment all you want with oil mixes in YOUR engines, but insisting someone else do the same, with the life of an obsolete powerhead on the line is pretty forward...
You going to help him find and purchase a powerhead if his wears out following your guidelines?
