Some Reasons for Poor& or Good Fuel Mileage
Poorly-Maintained Engines (Example)
(A) Worn O2 sensor can improve as much as 40% fuel savings (cq.com)
(B) Well Tuned Engine can improve as much as 4% on the fuel mileage (CQ.com)
(c) Clean Air Filter Can improve as much as 10% on your mileage (CQ.com)
(D) Using recommended clean oil improves mileage as much as 1-2% (CQ.com)
(C) Properly inflated tires can improve mileage as much as 3.3% (CQ.com)
(A) (example) Low tire pressure =2PSI =1% less fuel mileage
Inefficient driving & Planning Habits
(Driving habits) Consolidate errands Try to make one Trip
Extra weight (example) People, Luggage, Etc:
All the above are common culprits that cause low fuel economy no matter the type of vehicle
Getting the better MPG doesn't necessarily require a more fuel-efficient vehicle If your vehicle is paid for a new vehicle (example) a Hybrid or economy vehicle is going to take more of your pay-check than the gas pump will.
Fuel
Use only proper octane -rating Fuel that your vehicle requires. Octane has nothing to do with the gasoline?s performance just its volatility factor in combustion, don't use "premium" it is for use in Hotter combustion chamber environments like high-performance vehicles to reduce pre-ignition.
(AAA) say that only about 5% of cars sold in the US require premium gasoline. High Altitude is above 4000 feet and most vehicle that require 87 octane can use 85 at high altitude. Your owners manual has that information.
Our your Tires inflated properly?
Properly inflated tires have less resistance therefore improve fuel efficience by making it move easier. Under-inflated tires make it harder for the car to move which means that the engine uses more fuel, (example) a single tire, under-inflated by 2PSI can increase fuel consumption by 1%.
Servicing your Vehicle according to the owners manual will ensure your car's Power train and Engine will operate at maximum efficiency providing best fuel economy and return on your investment.
(A) To illustrate this point Dirty air filters, old spark plugs, low fluid levels will affect engine performance and fuel efficiency. Properly-maintained engine uses less fuel.
Driving habits
Avoid quick "jackrabbit" Starts -Hard accelerations, Hybrids need to operate at lower speeds. Avoid high speeds on the highway as speed increases the aerodynamic drag increases and the engine has to work harder and the harder it works the more fuel it uses. Driving 62 MPH instead of 75 MPH can reduce consumption as much as 15%. That is where Hybrids can save.
Lighten the load, Unnecessary weight in passenger and trunk compartments use more fuel
Keep windows closed open windows increase drag and can increase fuel consumption by 10% use climate control system on outside air or vent.
Use the cruse control EXCEPT ON WET ROADS this keeps your speed constant which save fuel.
Avoid long idling , Restarting the vehicle uses less fuel than letting it idle your vehicle idle for one to two minutes, For most hybrids this is not an issue as there gas engine shuts down at stopped
Pickup trucks Consider a tonneau cover or
