That is new to me. I have been running OS for a long time and never heard of that many gallons on any OS Engine, I race 2 - 3 times a month from March to September. This year I started with a brand new O.S. Speed .21 VZ-B V-Spec II 08/09 Worlds Edition and with all of the racing I have done, Im at about 7 gallons and that engine is shot. And yes I take care of my engines. so 16 gallons is good no bearing change, no pinching, all I can say is WOW
