Maintenance is critical in keeping your vehicle running its best and minimizing, poor fuel economy.
So, knowing the common causes, of poor fuel economy, is just the tip of the iceberg.

Danny’s Engineportal Poor Fuel Economy Tips – Fuel expands in heat, so to get your money’s worth; try to purchase fuel, during the coolest part of the day. For those in warm climates, this might mean a visit to the pump, early in the morning; after the underground tanks have had a chance to cool overnight.
Also, try to combine short trips, as the engine runs more efficiently when warm. If you’ll be idling one minute or longer, cut the engine. Consequently, this saves money at railroad crossings; when chatting out the window, or when picking up passengers.
These little tricks will go a long way, in helping combat, excessive fuel consumption. So, is your vehicle delivering poor fuel economy? Have you noticed a gradual or sudden drop, in the mileage you were once getting?
