I know that this is a pretty old thread, but I've also been recently dealing with really low fuel efficiency issues with the Pride I bought last month. What I've discovered are a couple factors here in the Philippines that adversely affect our car's fuel consumption. These are aside from the local driving/traffic conditions. First, and probably foremost, I've discovered by reading various maintenance/repair/service/shop manuals for the Aspires/Festivas/121s/323s (cars that use the Mazda B3 engines) that some engines of the same displacement (specifically the 1.3 Liter) were made with different compression ratios for different markets. I'm guessing this was done due to the varrying emissions requirements in the different areas. It seems like the North American and some European models had 9.7:1 instead of the 9.4:1 that we have here. Of course, the higher compression ration increases the power and therefore the fuel efficiency as well - major factor... Also, gasoline here is diluted with ethanol, I think about 10%. So that also increases the fuel consumption.
Can anybody out there confirm or deny my research?
