Hi guys, Changed the lower unit oil today, and using 80W-90 Lucas Heavy Duty Gear Lube. It meets GL-5 and GL-6 protection requirments. Anybody ever used this oil? It appears to have alot more protection additives than standard outboard lube. Lucas also states that this lube is excellent for outboard final drives. 1990 Yamaha/150 HP/ 2 Stroke
PS: Decided not to sell the V20.
