They are, according to this article, but not until 2017. Interesting facts about NGVs in the article, though. If crude oil/gas prices continue to rise, the U.S. could really benefit from a move to internal combustion engines that run on natural gas. According to the service recommendations we’ve seen for Honda’s Civic NGV, intervals are no different than what you might see with a gasoline-powered car — and they’re shorter than those typically seen with hybrid vehicles. So as a lube operator, would you prefer a nation full of hybrid and/or electric vehicles, or a nation full of NGVs?
