Anyone who thinks that the biggest expense you have with a car is at the time of purchase is wrong! The vehicle is subject to certain expenses such as IPVA, safe, licensing, maintenance, fines, tolls and, of course, fuel!
It is recommended to have an average of expenses to at least have an idea of how much money is spent per month, and thus adopt habits that control these expenses.

For calculate how much you spend on fuel, strictly follow these steps:
For a better view, see the example:
In the first fueled, his car had 2,000 km on it, while in the second it marked 2,500 km. So your full tank yielded 500 km. If you filled your tank with 50 liters, then 500 divided by 50 equals 10 km/L, which is your output.
On average, a liter of alcohol yields 70% of a liter of gasoline. So a super simple calculation can give you a good estimate:
Just multiply the value of gasoline at the gas station by 0.7. If the result is greater than the amount of alcohol, it is worth filling with alcohol. If the result is less than the alcohol value, fill up with gasoline.
See a practical example:
If a liter of gasoline costs R$ 3.50, multiply this value by 0.7. The result is 2.45. In this way, ethanol would be advantageous up to R$ 2.44 per liter. If it's R$ 2.45, it's the same. If it's more than that, it wouldn't make up for it.
It is worth remembering that this calculation is based on an average, and therefore does not take into account the specifics of your car's engine.
If you are interested in more precise numbers, fill up the gas tank and do all the calculations previously indicated, and then just fill with alcohol and redo the calculations. Thus, you will get a result of how many kilometers your car runs with each one.
That way, you can divide one result by the other to find a percentage for yield. It is estimated that this result is close to 70%. Look:
A flex-fuel car travels 11 km with 1 L of gasoline, and 7 km with 1 L of ethanol. 7 over 11 equals 0.68, or 68%. Almost 70% isn't it? It is recommended to repeat the habit from time to time to monitor the range and performance of your vehicle.
If you find it interesting, there is the possibility of downloading spreadsheets in Excel (or making your own) to systematize the calculations and better visualize them.
Didn't you understand much about that much calculus? Calm! There are apps available for Android and iOS that can help you at this time. This is the case of Consumo, Gasoleta, Fuelio, among others.
There are habits that require a high fuel consumption when taking over the leadership. It's important to be aware of this so that we can avoid as much as possible. Pay attention:
Before buying a car, if your objective is to save money, it is ideal to choose a car that has good consumption. After all, with fuel prices on the rise and tending to rise even more, who doesn't want to spend less, right?
