Does premium fuel make cars faster?
Premium-Sprit contains additives (additives) that should have all sorts of advantages. Premium brand petrol also has a higher octane rating (100 octanes). The fuel manufacturers promise quieter engine operation, less wear and tear, fewer emissions and lower consumption. The ADAC tested premium-class diesel and petrol in 2004 and found hot air in particular. Regardless of whether you add the premium fuel to your diesel or petrol engine, unfortunately, comparable results were disappointing.
Premium petrol mostly without the advantage
Drivers whose cars use regular gasoline have got used to the fact that the 95 octane fuel is no longer available. You are forced to fill up with 98 octane petrol at a higher price per litre – which neither harms nor benefits normal petrol.
Just as little does it matter if the engine needs 98 octanes (super) and gets premium fuel. The extra charge for 100 octane fuel benefits the oil company, not the engine. Power and torque remained the same or even decreased in the ADAC test. Only the Porsche Boxter benefited from the premium fuel – in an order of magnitude below the measurement tolerance of two per cent.
A petrol engine with premium fuel doesn’t get any faster. According to the automaker, there is no increase in knock resistance because the engines are designed for a lower octane number ex-works. And the additives hailed as beneficial are also contained in standard petrol (Super).
Premium diesel as a promotional bag
With diesel, it is the additives that are supposed to enable the premium variety to work wonders. The ADAC test determined a performance increase of between 1.6 and 4.5 per cent that was not noticeable while driving. There was no noticeable improvement in driving performance. An improvement in the emission values was not found.
Consumption fell by 1.0 to 5.6 per cent. In view of the additional costs for premium diesel, this is not a selling point. Unlike petrol, where normal fuel is no longer available, the diesel driver still has a choice.
Anyone who is willing to pay more money for a bottle of wine or a piece of premium quality meat will get a real equivalent. The money for premium fuel is, therefore, better invested in a fine drop and a good steak. There is no engine tuning from the petrol pump.
