did wheel alignment from kannur as advised by the vw dealer, for rs 400/. was filling up diesel at mahe when the attendant gave me a new info. she had filled about 40 litres of diesel when the auto cut off of the pump got activated. she then pressed a small button just inside the tube of the fuel tank opening when the fuel in the tube went down, she did this several times and got another 9litres of diesel into the tank
. gurus please explain this phenomenon. was it fuel getting in via the overflow tube. is it advisable to do this little trick.
i followed the tips suggested by naryanrmenon while driving home ( keeping the rpm needle about1400 ) on the highway and voila the mileage has come up to 20.6kmpl. only problem was that the autorikshaws were overtaking me with their drivers giving me bemused looks
