I think nitro fuels are pushed in America for much the same reasons HP of engines is always stressed in the advertising. If it's got more HP than the opposition it has to be a better engine. So if more nitro gives more power then you just gotta have it. The fuel manufacturers must love this because what they don't say is that then you'll be back sooner to buy some more because the engine will use it up faster .

And no, I don't use a compression bar like a diesel because that'd have to go right where the glow plug is. Which would make it kind of awkward putting on the glow ignitor .
