At Petrol Industries we apply a guarantee period of six months. If you have used the items but are unhappy about the quality, we will always refund your purchase amount.

Please note: this only applies if you purchased the items from our online store and you are unhappy about the quality despite proper use. We are also legally obliged to check the complaint and guarantee claim. In this case, the costs for the return are your own.
Please contact our customer service department if you wish to return items under the guarantee.
