Walking or biking does not consume fuel, and as such does not accumulate fuel cost. In most cases, public transport alternatives to cars such as buses, trains, and trolleys are viable options of reducing fuel costs. Due to the communal nature of ride sharing, the fuel costs of operating public transport are generally less than the fuel costs associ...
Also known as car sharing, carpooling is the arrangement between two or more people to travel to a shared destination in a single vehicle. Although a heavier car consumes slightly more fuel, it is usually much more efficient than two people driving separate cars towards the same destination.
Driving a smaller car makes a great difference – the fuel cost is about half for a small sedan than for a very large SUV. Similarly, drive with a less powerful engine than you need. Don't pay for an eight-cylinder engine when four cylinders work just fine. Unless you're hauling heavy loads on a routine basis, the extra cost of a bigger engine resul...
A properly tuned engine maximizes power and can greatly enhance fuel efficiency. But tuning the car engine is often done to increase horsepower – that's not the way to save on fuel. Make sure the tuner gets the message. Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent...
Make sure the tires are inflated to the right levels. Properly inflated tires can reduce fuel consumption by up to 3 percent. Your tires also lose about 1 PSI per month, and when the tires are cold (e.g., in the winter), their pressure will decrease due to the thermal contraction of the air. It is recommended to check tires at least monthly, prefer...
Gas mileage will improve by 1 percent to 2 percent if you use the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can reduce your gas mileage by a considerable amount. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1 percent to 2 percent. Also, look for...
There is no more obvious way to save gas than to drive a shorter distance. Plan your route carefully. With today's GPS route planners, it's easy to calculate a straight route with the fewest stops and diversions. It is also possible to judge which route will have the least traffic. Take highways instead of local routes or city streets when possible...

Aug 15, 2011 · A gasoline with an octane number of 92 has the same knock as a mixture of 92% isooctane and 8% heptane. To use our calculator, simply enter the Research Octane Number and the Motor Octane Number; click on Calculate and the minimum octane number, what you see at the pump, is returned.
Octane. Calculator. This calculator determines the minimum octane rating, also know as the knock index, by the formula (R+M)/2. Octane rating number is defined as a value used to indicate the resistance of a motor fuel to knock.

Why is high octane fuel better?
Octane rating is the measure of a fuel's ability to resist "knocking" or "pinging" during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88–90 (midgrade), and 91–94 (premium).
