Yesterday I rushed myself and grabbed what I thought was my two-stroke oil and didn't realize that it was quicksilver gear lube (same color/shaped bottle) until after I added it. The oil color was even the same as TCW-3 oil. I did add the correct amount though. Anyways its only a 6.5 gallon tank, but it was 91octane at $2.81 a gallon, so I was wondering if the gas can be saved. What would happen if I ran my motor on lower unit oil? The gas appeared to be clearer with the gear oil. I don't want to do any damage, so I might just get rid of it.
