Truck is diesel, so no problems there. My 2000 Trooper however is not, and I was hoping to get another 100K miles out of it.
This is what burns me about the E15 thing, and the Prius thing, and the Volt thing, and the general "new products that will save the environment!" bandwagon. It's all about buying new stuff. If they were all truly concerned about just the environment, they would actually be pushing people to hold onto their old vehicles until the vehicle falls apart. This kind of stuff simply ends the lifespan of perfectly serviceable goods much earlier than practical. Cash for Clunkers being a prime example of the process.
Giving someone the option of E15, or buying a Prius is one thing. Creating a situation where it is essentially mandated through the backdoor is another, and it's underhanded.
