Turbo Four-Cylinders in New and Used Cars Because of the lower displacement, four-cylinder engines are fuel efficient, produce fewer emissions, and are smaller than a six-cylinder.
Are BMW turbos reliable?
Consumer Reports’ reliability surveys have also found that manufacturers with a lot of experience building turbocharged enginesโAudi, BMW, Porscheโtend to have more reliable powertrains.
Is the BMW 2.0 turbo engine reliability?
BMW N20 Reliability Overall, expect the BMW N20 to be a reliable engine. It seems to be a slight improvement over the preceding N52 engine. A concerning common problem is the N20 timing chain. This mostly applies to N20’s produced prior to 2015.

Many of them are going well past 200K miles with good maintenance.
Is a 4-cylinder turbo better than a V6?
Modern turbocharged four-cylinder engines, when engineered properly, will either beat or match a naturally aspirated V6 in almost every category. Turbo-fours are lighter, more efficient, and can be more powerful than a naturally aspirated V6. The only thing that a V6 will always do better is towing capacity.
How long will BMW turbos last?
Turbos are designed to last the lifetime of the vehicle (or around 150,000 miles); however, it’s possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo.
Why do BMW turbos fail?
The main cause of turbocharger failure is oil-related โ usually due to either lack of oil or dirty oil. Turbocharger failures in BMWs seems to be caused by the long oil service intervals. (The dealer typically recommends oil changes every 12,000-18,000 miles, depending upon when the car’s indicator says to do it.)
Do turbo engines require more maintenance?
A turbocharger is essentially an additional component that forces more air into the combustion chamber. It makes the car produce more power as the result yet maintain fuel economy.

What are the disadvantages of a turbocharged engine?
- Overheating: A car turbocharger, if an intercooler is not used, can generate excessive heat in the engine.
- Turbo Lag: Turbo lag is a common problem faced by turbocharged engines installed in cars.
- Engine Wears Out At a Faster Rate: The faster you drive, the more stress you put on the engine.
Do turbos shorten engine life?
No. today’s turbochargers are designed to last the lifespan of the vehicle. The truth is, boosted engines require the same amount of maintenance and care that a naturally aspirated engine does.

Do I need premium gas if I have a turbo?
Not all turbocharged cars need premium gas, but it’s a more common requirement among turbos than other kinds of engines, thanks to the way these engines work. The name turbo comes from the turbine these engines use to inject more air into the air-fuel mixture in the combustion chamber.
Does a 4-cylinder have enough power?
It’s enough to make the engine run more efficiently so you get better fuel economy. Generally, a four-cylinder engine offers better fuel economy than a six-cylinder. Its better fuel economy is mostly due to having less horsepower but also by being smaller and reducing the weight of your car.

What causes a turbo to fail?
Most failures are caused by the three ‘turbo killers’ of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.
Is turbo engine good for long drive?
Turbocharged cars usually run at a higher RPM, so they tend to overheat more than the naturally aspirated ones. Overheating may cause the engine to stall mid-way. Therefore if you are traveling long distances, ensure you take halts at regular intervals to avoid overheating.
Do turbo engines last as long as naturally aspirated?
Some motorists love them, while certain purists would probably love to see them discontinued. This is because naturally aspirated engines last longer and are more reliable than their supercharged counterparts. Forced air engines work harder as they use higher compression and run hotter combustion chambers.
