7 Most Common Misconceptions About Fuel Efficiency by trantoan: 5:51am On Jul 13, 2018 |
Source: https://naijauto.com/car-maintenance/7-most-common-misconceptions-about-fuel-efficiency-142 Let's see what beliefs are outdated or even have never been correct about car fuel efficiency. Restarting the engine consumes more fuel than leaving it running, manual transmissions are more fuel-efficient than automatic transmissions, “warming up” the engine before departure is necessary, are some of the most common misconceptions about fuel efficiency. Naijauto will explain why. 1. Manual transmissions save more fuel than automatic transmissions Is your manual-transmission car saving you some fuel costs? Most likely not. Automatic gearboxes are now equipped with state-of-the-art technology that helps to reduce fuel consumption by at least as much as manual transmissions, sometimes even more. 2. Restarting the engine consumes more fuel than leaving it running idle Would you rather leave the engine running during red lights? In many cases, you really should turn off the engine and wait until it’s time to restart the car instead of letting the engine run idle for too long. Depending on the engine capacity, leaving the engine running with no load usually costs about 1 to 2 liters of gasoline per hour. If you just have to stop for a little while for the red light or until the traffic clears, do not turn off the engine. Otherwise, if you will have to stop the car for more than 30 seconds, then you should turn it off. However, do keep in mind that switching the engine on/off too often can cause the headset to crash. 3. The machine needs to be warmed up before departure This idea has become quite outdated because nowadays modern cars can roll smoothly just within a few seconds of startup. 4. The older the car is, the more fuel it’ll cost you Old cars are always fuel guzzlers, aren’t they? Not always, as this is not true in the case that your old car has always been timely and properly serviced. A 10 to 15-year old car may still have the same fuel consumption rate as a new car if the owner treats it right. The most important point to emphasize here is that you should know how to properly maintain that car. 5. Replacing the air filter can help to save fuel This is also an outdated concept originating from the time when all cars still had a carburetor. Nowadays, cars are equipped with a direct fuel injection engine with a computerized system that automatically adjusts the fuel / air ratio to appropriate levels. Replacing the dirty air filter might not improve the fuel efficiency, but that will still increase your engine’s performance. 6. Higher quality fuel leads to higher fuel efficiency The more expensive fuel you use, the more fuel you’ll save, correct? This idea might have been invented by the oil companies. Experts recommend that you use high-quality gasoline only when designated by the car manufacturers and in some special circumstances. 7. Additives and auxiliary equipment help to save fuel There is not much evidence of any “magic” factors that can save you more on fuel consumption than they cost. In some cases, these products can even damage the engine or increase the car’s toxic emissions.

Never buy a "Tokunbo" or used car without checking the Vehicle History Report. Most of these cars have undergone severe damage from Flood, accidents, vandalism, and have had the mileage tampered with. Please note: This is not a free service. It costs a mere pittance compared to the millions a vehicle may cost, and the thousands saved in future repairs. How to proceed: 1. Get the VIN from the vehicle, take a picture or type the VIN. The most common locations are shown. www.nairaland.com/attachments/7405097_20180713071650_jpega914c81a041c3d3a77bf2c41575b3ec0 Just beside the driver when the driver's door is open.

Review of your points: Point 1: Most manual drives comes with 5 Speed and MAY("may" because engine capacity affects fuel too) save fuel than most 4speed automatic drives except for CVVT, Hybrid, 7speed tronic (In some Mercedes Benz), VVT and other fuel saving modern technologies. Point 3. Cars with turbo chargers needs few minutes to idle so as to charge. If you "start and go", the car would lag. 5 Likes 1 Share |

No 3 still stands, steaming your car before your drive out is very good, is like humans doing morning exercise to make them healthier , same applies to car. not steaming it gradually kill the piston n rings and some other vital elements. For the air flow some injectors still come with air flow and once the airflow is bad, the vehicle won't move smoothly therefore leading to high fuel consumption. 2 Likes |

Please endeavor to make adequate research before posting next time. Higher quality fuel equals higher efficiency. Have you ever heard of octane number ( 2,2,4- trimethyl pentane) ? 2 Likes |

sorry bro.....cars are not human, does your blood change temperature while you sleep? no...the idea of daily steaming your car is to get the engine oil to heat up to optimal temperature, so.instead of burning fuel steaming your parked car, the smarter thing to do is = drive out ur car at slow speed(below 20_30 km/h) for 2-3 minutes before you speed up to your location. engine oil are now more efficient than previous generations engine oil 2 Likes |

vertueptime: As for me o, I prefer to warm it for like 6 to 7mins before zooming off especially in this raining season where there are many large pool of water to swim. I better burn the fuel than feel sorry in water. |
