Quicksilver Premium Plus in stead of Yamalube, doesnt matter if its under warranty or not they cannot make you use only their product unless they supply it to you. No sense in paying extra for the word "Yama" to be on the jug. TCW3 oil is TCW3 oil, you could buy the $10 a gallon Penzoil at Wal Mart and as long as it says TC3W on the jug its fine.
Sea Foam instead of Ring Free. Sea Foam is equally as good if not better, Ring Free is $48 for 32oz versus Sea Foam which you can get for about $15 for 32 oz.
Dont fall for the BS Carlos.... anything associated with or having the name Yamaha on it is priced way higher than other identical products on the market. Dont get me wrong, Yamaha is the best motor out there, just crazy the way they price their other stuff.
