Well I have had my E-tec for about three weeks now and it is running great on my 18 foot War Eagle. <br /><br />I have been hunting and fishing around two-three times a week and have around 20 hours on the engine. The gas millage has been very impressive and you hardly know it is on the back of the boat when your at idle. <br /><br />The boat has been running around 42-45 at 5500 rpm. I am using regular tw3 oil in the right now but plan on running the XD100 this summer.<br /><br /> Mark
