Hi Slowth-

Someone more knowledgeable than me should respond, but my understanding was that diesel engines don't benefit as greatly from pulse and glide because they don't suffer the same pumping losses from restricting the throttle like a gasoline engine.

I see your engine is turbocharged, but I'm not sure how that changes the equation.

My recommendation would be to check tire pressure and wheel alignment, and consider running a little extra tire pressure based on what you're comfortable with.

If you're making short trips, that might explain why you aren't hitting the published numbers.

You'll generally want to be in the highest gear you can get away with (reduce engine RPM), but you don't want to lug the engine to the point the turbo doesn't provide adequate air (avoid black smoke).
