This way you have a highly concentrated mixture (fuel cleaner with fuel). We recommend this if engines are really polluted, with noticeable signals such as: high fuel consumption, malfunctions, poor performance, irregular running of the engine etc.

II. Add the diesel injector cleaner to the fuel tank and fill up the fuel tank completely.

It is a less highly concentrated mixture than the 1st option, but the product has more time to do its job. We recommend the 2nd option if you want to clean the engine preventively. Preventive cleaning of the engine contributes to maintaining performance and minimizes the risk of malfunctions.

Whichever way you choose; both options are good. There is no right or wrong.
