Had a hard time justifying the extra price for two etecs bought new in 09'.. Just did some quick math. At $4.00 a gallon for gas (average over the past 3 seasons) 7,000mi. on each sled, average 22mpg . Gasoline savings alone = $2,500.00 (our old 550 fan got 11mpg). Burning half the injector oil at $40.00 a gallon = another $560.00 saved in injector oil for a total savings of over $3,000.00 over three seasons w/ two sleds.. Yeah, it was worth it to get the etecs!
