Regular Maintenance for Optimal Diesel Engine Performance

As the cost of traditional gasoline rises, diesel engines are becoming a more popular choice for family vehicles, in addition to their common use in fleet vehicles, semi-trucks, and pickup trucks. While diesel engines are exceptionally reliable, they do require regular maintenance to stay in top condition. At Santin Auto and Truck Repair Center in San Antonio, Texas, the expert mechanics use the latest diagnostic tools to ensure your diesel engine is running at its best.

Regular maintenance is key to keeping your diesel engine performing optimally. This includes changing the engine oil and filters at scheduled intervals. While diesel engines don't have electrical ignition parts like plugs and wires, regular maintenance is still necessary to ensure the proper function of other essential components. It's important to choose an experienced shop with mechanics who understand the unique needs of diesel engines.

Common Diesel Engine Problems

Despite their reliability, diesel engines can experience problems over time. Common issues include leaky gaskets, cooling system issues, overheating, air and oil filtration issues, fuel system restrictions, dirty injectors, piston scoring, faulty injection timers, and hard starting.

Leaky gaskets can lead to oil or coolant leaks, which can cause further engine damage if not addressed promptly. Cooling system issues can result in engine overheating, which can cause significant engine damage if not resolved quickly. Air and oil filtration issues can lead to reduced engine performance and can cause damage to engine components. Fuel system restrictions can cause poor fuel efficiency and engine performance, while dirty injectors can cause misfires, rough idle, and decreased power. Piston scoring can result in reduced engine compression, while faulty injection timers can cause poor fuel economy and engine performance. Hard starting can be caused by a variety of issues, including weak batteries or starter motors, bad glow plugs, or fuel system problems.

Esteban provided hands down the best customer service. My uhaul vehicle broke down and he was unable to fix it, it needed a tow. Esteban ensured I was safe and in a good place with uhaul sending a tow before he left. He even went out of his way to get me water and snacks since I have been on the side of the road for 3 + hours. There are good people in this world and Esteban is one of them. Amazing service and an even better human being.
