It Could also be gumed up, ie stickey rings etc. hard as it is to believe EXTRA OIL is NOT GOOD. The main difference inoil is the additive package. USE TCW III , at the recomended ratio. Also to quote a well know Engine Marinizer, in 07 they said with the Ethenial in the fuel, If you don't use up the fuel you bought today , add stabilizer. Today fuel does not store well, and loves to solidify in fuel system parts.
