Diesel Repairs in Etna Green, IN

Mast Service Center is located in Etna Green, and our auto mechanics are ready to take on any and all of your auto repair and fleet service needs, including diesel repair. Our owner, Leonard Mast, was already well on his way to becoming a diesel mechanic in middle school when he started working on the diesel engines at the family farm.

We’ll do any diesel repairs that we can to keep you moving and avoid needing to be towed.

“Mast Service Center in Etna Green does a terrific job in assisting me in keeping Borkholder Buildings company vehicles in excellent running condition. Also, for those who are not aware Mast also performs service work on forklifts as well. Their repairs are always completed on time and done correctly on the first visit to the shop.”

“The team did a great job on my 1997 F250 with the 7.3 L Turbo Diesel. I had a fuel leak, and in the process of fixing it they noticed a couple of fuel lines that were cracking and needed replacement.”
