which fuel is better for this car

[cliveld]

is super petrol better then special for this car.

i have hear that using super fuel the life of fuel system increases and so will the engines

if so i would like a confirmation on this please

Both are same except the difference of mere 3 octane.

Super 98 octane

Special 95 octane.

Super burns more efficiently and give 1% extra HP, nothing on life of engine or fuel system. Its crap.

Octane rating or octane number is a standard measure of the performance of a motor or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating. In broad terms, fuels with a higher octane rating are used in high-compression engines that generally have higher performance. In contrast, fuels with low octane numbers (but high cetane numbers) are ideal for diesel engines. Use of gasolines with low octane numbers may lead to the problem of engine knocking.

Best to check owner manual; however on Porsche i understand the engine management systems can alter the ignition in the cylinder subject to the fuel type. If the timing is wrong you get the knocking or pinking noise and loss of power under acceleration and potential misfiring.
