save gas has become more than a nice way to save, it became a priority with gasoline prices and greenhouse gases as they are. As someone who has managed several gas stations for one of the largest oil companies in the world, as well as ASE certified auto repair shop owner, I have heard almost every question about how to save gas and money you could possibly imagine. More importantly, I learned what works and what does not. As a result, I get 41 miles per gallon, highway, the car that is EPA rated for 36 miles per gallon. When my wife drives the same car with everything else the same it gets 33 miles per gallon.
1 Does filling up in the morning really save gas?
Absolutely! Gasoline expands and contracts with temperature changes. Tank can display 20 liters of gasoline in the morning, have some gasoline extracted, and still shows the same level of gasoline in the afternoon! Here's the thing, gas is sold by volume, so that one gallon of cold gas will give a mileage of perhaps 1.1 liters of hot gas (by example), but you're only paying for one gallon! Leave home a little earlier and fill your tank in the early morning hours when it's coolest. And, of course, find the lowest prices on reputable service stations. clean the outside usually means clean gasoline.
2 Whether topping off the tank more often when prices go up and save gas and money?
What it does is to save money on gas. It can be difficult to understand, but here goes: When evaluating any inventory that you are wasting, you may want to consider the replacement cost of inventories. Suppose you use a gallon of day, you have 22 gallon tank, and the prices are going up an average of one percent per day. I hope to never letting the tank get less than the last two gallons, so you go eight p.m. gallons between charges. If you wait a full twenty days to complete, you will spend 20 cents more per gallon, equaling an additional $ 4.00. But, if I was topping off every day, instead of 20 cents for every gallon you will have paid an extra one percent of the first day, an additional 2 cents the second day, etc., until the end of the same twenty days you find that you have spent only 2, $ 10 extra for the same amount of gas! It May not sound like much, but multiply that for a year and it adds up. In addition, ask yourself this: If you were told gas station attendant who pumps on the left will give you the same amount of gas, but it will cost you almost $ 2.00 less per fill-up rather than using a pump on the right side, which pumps the you use? Of course, the opposite is true when prices go down. In this case, that is all too rare, and will save money by waiting to save almost empty, because every day that passes brings more savings in cost per gallon.
3 Do proper tire inflation really save gas?
is not only proper tire inflation to save money on gas, but also can save your life. Improper inflation is the leading cause of tire failure, but we're not talking about getting the tires - we're talking about catastrophic tire failure, where the tire to explode, collapse, or an ordinary coming from the edge while you're driving. Remember the Firestone / Ford debacle? Firestone's claim was that Ford was not using the originally recommended tire pressure, causing a serious accident. That said, underinflated tires put more rubber on the pavement, increasing road friction and interfering with the tire's ability to dissipate heat from the road friction, causing a vicious cycle of creating more friction and heat. friction will hurt your fuel economy and heat will hurt your tires -. which in turn can hurt you if you fail to tire
4 I understand the dirty air filter hurting fuel economy, but not dirty fuel filter make your car use less gas?
Reduce the amount of gas to increase fuel consumption by May intuitive sense, but this is not how to save gas and money! Keep in mind that intuition tells us that it is more difficult objects to fall faster than lighter ones, and that Galileo proved wrong hundreds of years ago. What actually happens is that a clogged fuel filter causes the fuel mixture back. This will make the combustion air-fuel mixture less effective as it gets worse. Why? Without getting too in chemistry, fact is that gasoline burns best at the correct ratio of air fuel (14.7 kg of air for each pound of gasoline). Not enough air causes inefficiency as it does too much air. One of the traces of the mechanic picked up the car with too lean fuel mixture is a hydrocarbon or high oxygen reading of the exhaust gases. Hydrocarbons are unburned fuel resulting from a delay caused in this case, not enough petrol in the ratio of oxygen. In plain English, the engine must now work to make the same amount of energy. It always hurts fuel economy.
5 Can I save gas by opening the windows instead of running air conditioning?
Sort of, maybe, but not really. Assuming you are traveling at highway speeds, recent studies have shown that modern cars, with more efficient air conditioner than what their predecessors had, actually show very little, if any, difference in fuel consumption between running / C and have the windows open - and shave about 2% to 3%, assuming that everything is in perfect condition. It was not true for trucks, SUVs and other larger vehicles. Larger vehicles has deteriorated fuel in these tests with open windows, but s / o C, probably because of the much larger volume of interior seems almost like a parachute with such vehicles. Of course, you can save the most gas and money driving with the windows and A / C off, but it's not always possible.
6 Should I leave the car, if you'll be idling for less than three minutes because it takes more gas to run cars?
No more. In fact, that three minutes is a rough figure, at best. In any case, modern cars - many going back to the early 1980s and the late 1970s - are computer-controlled fuel injection, which is the amount of fuel needed to restart a warm engine is equal to as little as 30 seconds of idling. Clearly, letting the car idle, even for just three minutes is not to save gas and money. If you know it will be a few minutes and you are in traffic would not be better to shut the engine off. In addition, modern cars do not need a warm-up period of more than thirty seconds when cold start - unless you're in extreme cold, where you'll probably want to get a block warmer

7 I keep seeing the mechanical devices that were supposed to save money on gas. Work?
I saw all kinds of gizmos and I'm sorry to say, and many of them make sense on paper, most of them do not seem to work. I must also admit that a lot of the problems is that people are trying to find a way around fixing major mechanical failures. Always keep your vehicle in good condition (one of the best ways to save gas and money in the long run) - connect additional devices to the engine with low compression or some other deficiency is not likely to deliver good results. It's like trying to use a squirt gun to put out major forest fires. As for cars that are in good condition, some things may work, but if your car is under warranty, you must be careful that the gadget does not void the warranty. Right now I'm following the "hydrogen from water" concept, where the car is electricity used to separate water into hydrogen and oxygen, which is then drawn into the air. I've seen some impressive demos of them even used by government agencies. I am looking to install one yourself.
8 Are additive save gas?
This is a broad topic. broad answer is that - depending on the situation (please avoid fighting forest fires with squirt guns!). Brand-name additives for cleaning fuel injectors are generally applicable in that dirty injectors and valves will most definitely hurt the economy. As a fact, the older vehicles have often been able to save my customers a lot of money to repair the carburetor by running a very high concentration of injector cleaner through the system. Obviously it was not for the carburetor, which are mechanical, "hard parts" failure. With newer cars have to be careful, with just about any car from them in 1980-up, make sure that each product that will pass through the intake and exhaust system is a sensor for sure! Also, instead of using premium gas in a car that does not call for it, I recommend using regular gas and pouring a bottle of injector cleaner in with the fill-up every two months or so, depending on how much driving to do.
9 What about oil additives?
This is a conditional "Yes". There is an old stand-by, Marvel Mystery Oil, which many mechanics will tell you is really for the transmission fluid. Marvel Mystery Oil are two basic things: First, when added to your gasoline is worse than carbon build-up in the combustion chamber, thereby decreasing before ignition. If you do this, and saw smoke coming from your exhaust you were using too much or you're sure to have carbon buildup, which means a temporary smoke caused by burned-off carbon is a good thing! First of detergent, motor oil, you've come to use the "de-coke" his engine on a regular basis - the same basic thing. Second, when added to oil provides extra bit of cushion and lubrication to your valves and valve stems. In any case, this situation should not be a problem on newer cars. STP Oil Treatment is good in the sense that the viscosity index improvers. Do not ignore the instructions on the label as you will end up being similar to using too high viscosity of engine oil. STP will also help reduce engine wear by leaving a protective film when you start the engine, when most engine wear takes place normally, because there is so much oil pressure at the time.
10 Are you with PTFE oil additive help you save gas?
Yes, but according to study after study, only when he or his rest was present in the engine. PTFE undoubtedly reduce friction. What is in doubt is the ability to get to actually bond the engine parts. It is necessary to extremely high temperatures to get the PTFE bond to the metal - the temperature does not get except maybe in the combustion chamber itself, except it all bearings, camshaft (s), rocker arms, valve stems, lifters .. . well, you get the picture. However, while the additive is still in its engine provides better protection. It is expensive to add to each oil change, but for the collectible cars May want to go with him, although saving gas usually goes hand in hand with the driving collectible.
11 owner's manual says that I only change oil every 7500 miles. Is my mechanic is trying to pull one on me when he recommended every 3000 miles, or I'll get better gas mileage this way?
will get better gas mileage - especially in the long run. Frequent oil changes will help prevent engine wear and sludge, both of which will kill the engine efficiency as they get worse. As for the difference in the recommended oil change intervals, they are both correct. How? If you read the owner's manual carefully, as in the fine print, you'll find something to the effect that is difficult or severe conditions you should use a shorter interval. Here's a question: what makes it tough? Heat, cold, dust, humidity, stop and go traffic ... I do not know about you, but I can not think of any place that has none of those conditions! So why do they print that is in use? They want to be able to sign up low-cost labor, while giving you real guidelines. Go with 3,000 miles unless you are using synthetic oil. And, yes, synthetic is better and I strongly suggest you still use in cars that call for it in the owner's manual. I use the manufacturers recommended oil viscosity. This, too, can make a difference in fuel economy and warranty.
