#94 of 96 Horrible gas mileage
Jun 03, 2011 (12:10 pm)
I live in Canada and I own a 2004 Mazda six speed. I drive to kelowna twice a week which is around 120km (62 miles). My gas mileage is horrible, I am getting 19 liters (just over 5 galons) to 100km (74.5 miles) or 350km (218.5) to a tank. I dont think the car should be this bad on gas. What do you guys think? Plus when i go up hills the car smells terrible, not like suffer but like oil and gas mix. My engine light turned on for a week but turned off. Any suggestions

It sounds to me as if your catalytic convertor is failing, and I would suspect that your ignition coils may well be shot too. The mileage you are reporting sound like stop and go mileage, so if you are not doing a lot of idling whilst stuck in traffic, then I think you should definitely assume something is wrong. The fact that your CEL came on says something bad has happened and you need to know what error code was logged before you attempt any further diagnostics.
