❗❗Service Reminder❗❗
I know for most of our customers its not a issue. But please keep up with your maintenance! It will save you in the long run! Also Its important to get your vehicle maintenance done at a actual repair facility. Not a quick l**e. The reason is, the repair facility will usually also perform a multipoint inspection by certified Technicians as part of the service. So you can get ahead of issues you may not even know about. Here just a few pictures from this past weeks offenders. And one "do it yourselfer" That tried to re-seal his oil pan by adding another gasket to the original❗️❗️😳🤯

For any of your trucks service, repair, or performance needs, Call Whittyz Diesel ❗️❗️281-964-2886❗️❗️
