Choose The Best Gasoline For Your Car

We believe that, for many drivers, refueling your car is as easy as going to a buffet restaurant. However, most of us are still a little confused that how to make the gas things best. Do you really know what's the best gasoline for your vehicle?

First, let's take a look at all types of fuel we can access now.

Generally, there are two kinds of fuel, diesel and gasoline. While diesel is far less common than gasoline, more and more European cars use diesel engines, which can provide high torque at low rpm. And it usually takes a rather lower price than gas. But be cautious, if you're not driving a diesel vehicle, never think of trying to fuel your car with diesel, and vise versa. Otherwise, it could be dangerous.

And speaking of gasoline, there're three types of it. 

• 87 (Regular), low octane rating, and low price
• 89 (Plus/Midgrade/Special), medium octane rating, and medium price
• 91 - 93 (Supreme/Premium/V-Power), high octane rating, and high price

P.S. the higher the octane rating, the better the resistance to shock and explosion. But it does not mean that the Premium is the best, so how to choose the best one for your vehicle？

Actually, it could be simple. Your vehicle owner’s manual will give you the recommendation. And if you have a diesel vehicle, there's no second choice.

• Turbo cars should use high-grade gasoline, while naturally aspirated cars can use low-grade gasoline.
• Most small-displacement (under 2.5L) vehicles can use 87 gasoline.
• Most European cars with turbocharging must use 91 gasoline to avoid damage to the engine.

If the octane you used is lower than required, although saving some money, but it will risk burning valves, pistons and other parts. On the other hand, if it is higher, the engine will overheat for a long time and will in turn reduce power and increase fuel consumption, which could do huge damage to your engine.

And you might also have noticed that the fuel prices can be vastly distinctive in different gas stations. What causes those differences？

• Crude oil prices
• Refining costs: Refining costs vary from region to region, with each region requiring different gasoline formulations for air pollution and refineries refining various crude oils differently. Other additions such as detergents and ethanol also affect the price.
• Federal, state and local taxes
• Operating costs: Different gas stations are different in rental rates, different traffic volumes, and operating efficiencies, but everyone has to make money, so pricing will vary.

Just choose the gas station according to your own situation.
