You have lots of choices when filling up your vehicle. Different gas stations have different prices, and while they all have the same gas, you then have a decision to make: premium or regular? A few higher-end cars will require premium gas, but what about “premium recommended” or just regular cars? You could ask a trusted German auto mechanic in Albuquerque, NM about your German-manufactured car. Knowing what type of gas to use can be important to your car’s engine health and efficiency.
How gasoline works
The difference between regular and premium gas requires a bit of gasoline and car knowledge. Every vehicle runs through the process of combustion. The injected gasoline is ignited by the spark plug in the engine compartment, but the spark plug doesn’t fire right away. There’s a mix of air and fuel running along the spark plug during that time. Should the air and fuel mixture fire off too soon or leak out, it can cause engine knock, which is a clunking sound from the engine. It’s not something that requires a German auto mechanic in Albuquerque, NM, but if it happens too often or even when using premium gasoline, you’ll want to take your car in to a shop for service.
Premium gas and regular gas are separated based on octane. Octane is found by the different combinations of hydrocarbons in the fuel. The higher the octane, the less chance to get the engine knock. Premium fuel is usually around 91, while regular is around 85 to 87.
Mileage may not vary
In terms of creating the energy to fuel the engine, premium and regular gas don’t really make a difference. A car running on premium gas doesn’t get more miles to the gallon. A higher octane lets car engines run at a much higher performance level, making for much higher performance driving. That’s why race cars use high-octane fuel—to get the most out of their engine.
Premium not for everyone
While premium may seem like the better choice all the time, it’s not. Premium gas is made for engines that run at a higher performance. Lower performance engines don’t need the higher-octane gasoline. Instead the higher-octane will be going to waste and you’ll be spending extra money you didn’t need to. To find out if your car would benefit from premium gas, check the owner’s manual. A performance car, like some BMWs and Audis, will likely require premium gasoline. You can also check with a German auto mechanic in Albuquerque, NM to find out the best option for your engine. They’ll be able to tell you if you need premium gas.
