G'day all. I have a 94 Yammy 115 V4 2 stroke. It is oil injected. I have 2 60litre alloy tanks under floor. I have fuel in them that is about 3 months old now. I run a very good (fine) filter and water seperator. My question is, will my filter pick up any crap in the fuel that could cause varnishing etc or am I better off either syphoning the fuel out and starting again, or using a re-freshing product?<br /><br />Cheers all.
