P&G: you're doing it wrong
That's my conclusion after I changed my driving style to pulse more aggressively. I believe this resulted in better coast-to-pulse ratio and my best ever FE with the car (6.4 l/100km, 36MPG). All that in much colder weather than the previous best (but with the help of narrow 145 tires).
Unfortunately today I drove into a deep puddle during Rally Barborka Bis, the engine died and made unpleasant sounds when I attempted to run it after a while. I hope it's going to live
