Hello everybody,

I'm new here, but I've been reading with interest for a while the threads on the forum.
I own a Hyundai Accent with a 1.3 SOHC engine, which has a pretty good mpg rating, but I always try to improve it. My personal best was a 51 mpg and the official rating is 45 mpg for highway driving.
The fact that I live in Romania, makes hypermilling a very different thing from what I've read here. Usually extra-urban driving implies a legal speed limit of about 55 mph and lots and lots of villages and curvy roads to drive through.
It has been a month now since I installed on my car a lpg system. This gives me a financial advantage, because lpg is about 60% the price of petrol. Also lpg burns cleaner.
All is good, except the fact that when switching on lpg, the car has worse mpg.
It is not a big difference ( about 10% ), but I don't like it. I think that this is also because the car feels lazy when running on lpg, but I did manage to get the difference in mpg to a 3-5% compared to gasoline.
Is there any special advice for driving a lpg car ?
Are the usual hypermilling techniques different for this kind of fuel ?
