NEED advice gas additive.. oil?

Maybe your client has an old SAAB with the 2 cycle engine?  Years ago, they used to add top oil to the gas to lube the valves.



I've listed things for friends, and some stuff just isn't worth listing on ebay.

Motor oil will reduce the octane rating of the fuel, causing the computer to retard the timing, making less power. Also it won't do the O2 sensor any good, not to mention the catalytic convertor.
