We just bought a 2004 Sugar Sand Mirage 18' with the 240 Mercury EFI jet engine. The manual states to use "Premium TCW3 oil". My friend who has the 210hp version of this engine "swears" by ONLY using the Mecury 2 stroke oil.
Anybody have a 2 stroke Mercury jet engine - what hp, efi or not, and what oil do you use?
