Ideally, the Verstärker Octane booster needs to be added to your car’s fuel tank on every fuel fill-up.

The ideal way to use an octane booster is to add it to your car’s fuel tank on every fuel fill-up

Many new cars automatically respond to variations in octane numbers. For example, “ECU’s learn system” slow down spark timing to compensate for less-than-optimal octane. Slowing down the spark timing involves retarding the point in the engine’s cycle when the spark plug fires. This situation reduces the combustion temperature to prevent knocking and pre-ignition.
On the other side, ECU can advance the engine when detects fuel with higher octane. When you return to lower octane, your engine will knock and then return to its old ways. So, we strongly recommend using Verstärker Octane booster each time refueling.
