To avoid the risk of a manufacture refusing to honour a warranty, we recommend that all services be carried out in accordance with the manufacturer’s specifications:

1. Fluids used should conform to manufacturer’s specifications.
2. Parts manufacturers and suppliers (especially for filters) should confirm that their parts perform at the same or a higher standard than the original parts.
3. It is recommended that ISPs purchase parts from manufacturers that manufacture on behalf of the OEM as well as the independent aftermarket. Good examples of these types of brands include Mahle, Bosch, NGK, GUD, Hella, Temot, Fram, Safeline, Monroe, Mann and Hummel, amongst others.
4. ISPs should only use parts from suppliers that provide indemnity for damages (including consequential damages) should their parts be found to be at fault.
