I have a 97 GTS I just bought recently. I mixed the wrong oils TC-w3 multipurpose 2 stroke Valvoline oil blue bottle, mixed it with Pennzoil synthetic blend (big yellow bottle) XLF TC-w3 NMMA. Marine engine extended life formula. It had about a 1/4 of tank oil of the Valvoline and I added another 1/4 tank of Pennzoil. So 1/2 tank total. Ran it on a full tank of gas. It ran great until last run. Started bogging a lil bit. I know I have to drain all the oil out of the tank and need to use synthetic oil only for the 717 engine. What else should I do after I drain all the bad/mixed oil out? Before filling the tank back up? Let me know if you can help? Or anyone else reading this forum. Much appreciated. Joe Go
