i have a couple questions regarding my 08 vx deluxe waverunner. First i have been looking on the internet for an oil filter, i was going to us a K&N filter but i noticed there are two, the 303 and 204, i have read that the 303 is the one i need but when i got the yamaha oem part number for the oil filter and cross referenced it the 204 is the one that matched. So has anyone used K&N oil filter, if so which one did you use or which one will work? Second i was going to use yamalube 20-40 but cant seem to find it, can get the 10w-40 but not the 20. Will it make much of a difference if i just use the 10w-40? thanks, any ideas welcome
