Should I drive fast or slow when low on gas?
Slow Down and Drive Conservatively
About 55 miles per hour is the optimum speed for most cars. Kick it up to 65 mph and you are 8 percent less efficient; at 80 mph you are 28 percent less efficient. Slowing down can also mean reducing your carbon footprint.
If you speed up to try to make it to the gas station quicker, you might not even make it there. Since vehicles are the most fuel-efficient at 35 to 45 mph, it's important to drive slow, if possible. If you're traveling on a fast-moving highway, however, you should drive at the correct mph.
You should also drive at a constant and slow speed, ideally below 50 miles per hour. Frequent throttling and coasting should also be avoided to lower gas consumption. Try using the left or middle lane of the road. Touch the pedal only to maintain a constant speed.
When your engine doesn't have enough fuel, it can cause cylinders to misfire. But the biggest risk is if you're traveling at high speeds and RPMs, your car's computer will request a richer air-fuel mixture to prevent damage to the engine. If the fuel pump cannot deliver enough fuel, it can cause an engine knock.
The harder you accelerate the more fuel you use. In the city, you can use less fuel by easing onto the accelerator pedal gently. To be as fuel-efficient as possible, take 5 seconds to accelerate your vehicle up to 20 kilometres per hour from a stop. Imagine an open cup of coffee on the dashboard.
75 mph (50% more power), but 60 vs. 70 mph is worse; nearly 60% more power to maintain speed, and use 36% more energy (you use 60% more power, but for less time).
Generally speaking, you will be able to drive between 30 and 50 (0r more) miles even after the light comes on. Which means that even if the gas light comes on, it may not be time to panic yet. You do still have time.
“Typically, it will light up when the tank is below 10% to 15% of its capacity.” In general, after the gas light comes on, Muñoz says it's safe to drive about 20 to 30 miles in a smaller vehicle or up to 50 miles in a larger vehicle.
Engine misfires: When running on empty, your car's fuel pump can start to take in air, which means the engine isn't consistently getting the gas it needs. This often results in engine misfires. To you, this will likely feel like your engine has a loss of power, hesitation or vibration.
Does AC use gas?
Generally, the air conditioner uses gas, so use it wisely. If temperatures outside the car are pleasant, open the windows and let your car cool down for a few minutes before using the vent or AC on low to keep a comfortable air flow in the car. Your air conditioner works the hardest when your car is the hottest.
Cruise control can help you become more fuel-efficient and can help you save an average of 7-14% on gas thanks to its ability to maintain a continuous speed. In comparison, the constant change in acceleration and deceleration of the driver placing their foot over the pedals can eat more gas.
The average driver only saves about 26 seconds of time per day by speeding. In fact, the faster you drive, the less time you save. For example, increasing your speed from 40 mph to 50 mph saves an average of 3 minutes, but going from 80 mph to 90 mph saves less than 1 minute.
You might surmise that when your car runs out of gas the engine simply stops running, but it typically doesn't happen that way. Most often the car will show signs of "fuel starvation" that include engine sputter, intermittent power surges, and perhaps even engine backfires.
Choose a clean, dry garage or storage facility, as damp air can cause rusting. Ideally, store your car in a climate-controlled facility. Fill the gas tank completely full. An empty or low gas tank will lead to internal rust as condensation and moisture builds within the tank.
The less fuel in your tank, the greater the risk of running out completely in a bad spot. While different experts have different suggestions, it's typically agreed that drivers should refuel their vehicle when they have anywhere between a quarter of a tank or half of a tank left for maximum efficiency.

Yes - Throttling losses are minimized with a fully-opened throttle. However, running at full throttle is only part of the way to get peak efficiency. but - The engine must also be operated at peak torque, which means it must be loaded to bring the RPMs to the peak torque range.
Avoid Speeding. Increasing your highway cruising speed from 55mph (90km/h) to 75mph (120km/h) can raise fuel consumption as much as 20%. You can improve your gas mileage 10 – 15% by driving at 55mph rather than 65mph (104km/h).
Fuel economy for a light-duty vehicle going 80 miles per hour (mph) is about 27% lower than when traveling at 60 mph. Between 40 and 50 mph is the optimum cruising speed for the best fuel economy in cars and light trucks, according to an Oak Ridge National Laboratory study of 74 different vehicles.
How far does a car travel at 70 mph?
By definition, driving 70 MPH means that a car will have driven 70 miles in one hour. Or better yet, 70 miles in 60 minutes. So in one minute it will drive 1/60 of 70 miles [ 1/60 * 70], or 70/60, which equals 1.167 miles.
Yes, it is generally recommended to keep your gas tank at least half full for a few reasons. First, it can help prevent the fuel pump from overheating, as the gasoline in the tank helps to dissipate heat and keep the pump cool.
Call for Roadside Assistance
If you are not a member of a 24-hour roadside emergency assistance program, contact a friend or family member to take you to the nearest gas station to buy a container of gas or to have them bring you one.

Yes, in most cases, one gallon of gas should be enough to start a car, especially if the car's tank is nearly empty. However, the exact amount of gas needed to start a car can vary depending on the car's make and model, as well as the car's fuel efficiency and the condition of its engine.
