I'm driving a second-hand (not sure how old - pretty beat-up though!), 4-speed VW Golf, 1.4 l (I guess) engine, and commuting 25km each way to work every day, with the occasional longer journey (100 km or so).
I've been trying to use the highest gear possible that keeps the car moving without stalling (i.e. lowest possible r.p.m.), and am using about 8.4 l (unleaded) fuel per 100 km (about 33.6 m.p.g., if I've done the conversion right).
I would like to know if there is an optimal r.p.m. value where the fuel burns most efficiently (i.e. minimising unburnt fuel emissions) while still maximising fuel efficiency (minimum fuel used against maximum distance travelled)?
If so, is there an easy way to find it, or should I just carry on doing what I've been doing?
