Get the most out of your gasoline/petrol.

Thought i'd share this with the bro's.

Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the gasoline, when it gets warmer gasoline expands, so buying in the afternoon or in the evening....your gallon is not exactly a gallon. In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays an important role. A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.

When you're filling up do not squeeze the trigger of the nozzle to a fast mode. If you look you will see that the trigger has three (3) stages (Normally): low, middle, and high. In slow mode you should be pumping on low speed, thereby minimizing the vapors that are created while you are pumping. All hoses at the pump have a vapor return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you're get ting less worth for your money.

One of the most important tips is to fill up when your gas tank is HALF FULL or HALF EMPTY. The reason for this is, the more gas you have in your tank the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Less open space = less evaporation.

Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up--most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

The last part in bold is the most important actually. Dirty fuel costs people untold amounts of money in repairs each year. I know because i've worked as a mechanic and drained many tanks and changed many fuel filters/tanks for this very reason.

I've heard most of this over the years just not in one place...good shit

[IMAMEX]

this is awesome & I think I've done all these wrong things. thanks!

[Axeman]

good job on the tips, I have been doing this for some time now, it's real funny pumping the gas in slowly with cars waiting for you to get done.

haha. my friend show me this last friday.

it was on a car forum, the guy who posted this was supposed to have worked for like...some oil company or something.

[Fubar]

Good advice I hope it works.

Jaja...I got this from a forwarded email. lol

[donkeypunch]

hell yea all the drivin ninjas need to see this

Good advice thanks man.

The filling up when half full thing interests me because I figured that the more full your tank is, the heavier the car and therefore more fuel consumption occurs.

awesome post thanks!

From Consumer Reports:

Fuel Economy: Consumer Reports' tests show how to get the best gas mileage.
The best way to burn less fuel is to buy a car that gets better gas mileage. But our tests with a Toyota Camry and other vehicles show there are ways to minimize what you spend at the pump with your current car.

Drive at a moderate speed. This is the biggest factor. You may have to be a little patient, but driving at 55 mph instead of 65 or 75 will save you money. When we increased the Camry's highway cruising speed from 55 mph to 65, the car's fuel economy dropped from 40 mpg to 35. Speeding up to 75 mph cost the car another 5 mpg. One reason is that aerodynamic drag increases exponentially the faster you drive; it simply takes more fuel to power the car through the air.

Drive smoothly. Avoid hard acceleration and braking whenever possible. In our tests, frequent bursts of acceleration and braking reduced the Camry's mileage by 2 to 3 mpg. Once up to speed on the highway, maintain a steady pace in top gear. Smooth acceleration, cornering, and braking also extend the life of the engine, transmission, brakes, and tires.

Reduce unnecessary drag. At highway speeds, more than 50 percent of engine power goes to overcoming aerodynamic drag. So don't carry things on top of your vehicle when you don't have to. Installing a large Thule Cascade 1700 car-top carrier on our Camry dropped its gas mileage from 35 mpg to 29 at 65 mph. Even driving with empty racks on the car reduces its fuel economy.

Don't use premium fuel if you don't have to. If your car specifies regular fuel, don't buy premium under the mistaken belief that your engine will run better. The only difference you'll see is about 20 cents more per gallon. Most cars are designed to run just fine on regular gasoline. Even many cars for which premium is recommended will run well on regular.

We have found that the differences are imperceptible during normal driving. Check your owner's manual to find out if your engine really requires premium or if you can run on other grades.

Minimize driving with a cold engine. Engines run most efficiently when they're warm. In our city-driving tests, making multiple short trips and starting the engine from cold each time reduced fuel economy by almost 4 mpg. Engines also produce more pollution and wear faster when they're cold. When possible, combine several short trips into one so that the engine stays warm.

Keep tires properly inflated. The Camry experienced a 1.3 mpg loss in highway fuel economy when the tires were underinflated by 10 psi. More important, underinflated tires compromise handling and braking, and wear faster. And they run much hotter, which can lead to tire failure. Check the pressure of your vehicle's tires at least once a month with a tire gauge. The owner's manual explains how to do it.

Buy tires with lower rolling resistance. A tire's rolling resistance can add or detract another 1 or 2 mpg. In our tire ratings, look for high-rated tires with low rolling resistance. They generally won't cost more, and replacing a worn tire could save you more than $100 a year in fuel.

Avoid idling for long periods. Think of it this way: When you're idling, your car is getting zero miles per gallon. When we let a Buick Lucerne, with a V8, idle for 10 minutes while warming up, it burned about an eighth of a gallon of gas. A smaller engine would probably burn less, but idling still adds up over time. As a rule, turn off your engine if you expect to sit for more than about 30 seconds. An engine warms up faster as it's driven anyway.

MYTH BUSTERS

Morning fill-ups. A common tip is to buy gasoline in the morning, when the air is cool, rather than in the heat of the day. The theory is that the cooler gasoline will be denser, so you will get more for your money. But the temperature of the gasoline coming out of the fuel nozzle changes very little, if at all, during any 24-hour stretch. Any extra gas you get will be negligible.

Air conditioning vs. opening windows. Some people advise you not to run the air conditioner because it puts more of a load on the engine, which can decrease fuel economy. But others say that opening the windows at highway speeds can affect gas mileage even more by disrupting the vehicle's aerodynamics. Our tests show that neither makes enough of a difference to worry about. Using air conditioning while driving at 65 mph reduced the Camry's gas mileage by about 1 mpg. The effect of opening the windows at 65 mph was not even measurable.

A dirty air filter. Our tests show that driving with a dirty air filter no longer has any impact on fuel economy, as it did with older engines. That's because modern engines use computers to precisely control the air/fuel ratio, depending on the amount of air coming in through the filter. Reducing airflow causes the engine to automatically reduce the amount of fuel being used. Fuel economy didn't change, but the Camry accelerated much more slowly with a dirty filter.
