Mitsubishi strongly recommends that scheduled services are performed by your Mitsubishi dealer. However, services can be carried out by another qualified serviced provider if the service is performed in accordance with the requirements detailed in your vehicle Service and Warranty Customer Information Booklet using proprietary oils, coolant and fluids where specified.
If servicing is performed by someone other than a Mitsubishi dealer, and a concern occurs which is a result of incorrect servicing using other than Genuine Parts or specified lubricants, then warranty will be affected and denied on that or related components.
