Are all the additives compatible with all engines?
You cannot add oil additives in the following engines: PSA (EB) 1.2 PURETECH and (EP) 1.4 and 1.6 THP. The timing belt of these vehicles passes through the engine oil. Therefore, PSA prohibits the addition of any additive in the oil of the mentioned engines.
Can I add a larger dose of additive for a better result?
Overdosing an additive will not change the efficiency of the product. We recommend that you respect the dosage and the instructions for use indicated on each of our products.
