There's very much a chicken-and-egg argument here. The fuels aren't available. The engine technology and the powertrain technology won't be there to support the use and the consumption of those fuels. Conversely, the same applies.
I will say that it's our position among our membership.... You won't hear, traditionally, a stampede of support for higher levels of biofuel, and in particular ethanol, among our members. That's not to run it down as a fuel. It's simply to say that higher level blends within gasoline, separate from E85—so I'm looking at E15, E20, and beyond—still have not been proven in terms of the durability on the current existing vehicle fleet, and in particular, on those 15- to 20-year-old trucks we were talking about that people like to keep and maintain. Similarly, the jury is still out in the United States on this. There are several lawsuits flowing. I'm not looking to pick an argument with the renewable sector at all, but simply to say that we urge caution in that respect.
The other thing about boutique fuels is that everybody these days seems to have a panacea to introduce into a litre of gasoline or diesel to make it go further and stretch its efficiency. We don't support drop-in requirements for fuels. We need good quality fuel. Generally speaking, plug-and-play compatibility with new additives is not our preference until there's been durability testing done, and in both the United States and Canada, obviously, to support that.
