Is the 1. MultiAir a good engine?
Lots of power combined with serious reductions in emissions makes this a very good engine. Gasoline engines are generally lighter and less complex than diesel engines, which makes them easier (and often cheaper) to maintain.
Do turbos reduce engine life?
Another misconception is that turbochargers drastically reduce engine lifespan. With proper care and maintenance, a turbocharged engine can last just as long as a naturally aspirated one. The turbocharged option is more recommended for those who use their car on long roads, in uphills, or in rough patches. The turbocharged engine allows acceleration, more power, and greater vehicle control. The normal engine is more recommended for city life.
Do turbos require premium gas?
The simple answer is that turbocharged cars can indeed take advantage of premium gas and most manufacturers recommend using it. Some high performance cars need premium gas to run while other turbocharged cars are designed to run on regular gas as well if the manufacturer has tuned it accordingly. Engine computers can usually adjust their timing to account for the increased octane levels, so if you put premium gas in a regular car, you probably won’t notice anything. However, some engines are not designed to burn higher-octane fuel, and you may see a reduction in performance and fuel economy.
