Customer Reviews

Your business is very appreciated.

G and stars

Santin Truck repair has been a blessing for me in getting a qualified and certified Spartan chassis repair facility for my Newmar Essex coach. They helped me with road calls with issues. They have serviced my coach doing preventative maintenance. I have had paint touch work done and they did an excellent job. I have no issue recommending them.

Keeping a fleet of heavy-duty vehicles running smoothly is critical to meeting deadlines and protecting your company’s reputation. These trucks work hard every day, often under extreme loads, long hours, and challenging conditions. One of the simplest but most important maintenance tasks you can prioritize is regular oil changes. Consistent oil service plays a major role in fleet efficiency. At Santin Auto & Truck Repair Center, we provide expert fleet vehicle maintenance in the greater San Antonio area. Here are four reasons why staying on schedule with oil changes is essential for your heavy-duty fleet vehicles. Protect Engine Components From Excessive Wear Engine oil lubricates moving parts, reducing friction between critical components. In heavy-duty fleet vehicles, engines are constantly under stress, which can cause oil to break down faster than in light-duty vehicles. When oil becomes dirty, it can no longer provide proper protection. Regular oil changes provide clean, effective lubrication, helping to minimize wear and extend the life of expensive engine components. Maintain Optimal Engine Performance Fresh oil helps engines operate at peak efficiency. Over time, contaminants build up in the oil, restricting flow and reducing performance. This can lead to sluggish acceleration, reduced power, and poor overall drivability. By keeping up with oil changes, fleet managers can help ensure engines remain responsive, even under heavy loads and demanding driving conditions. Improve Fuel-Efficiency Across Your Fleet Old or degraded oil increases internal engine friction, forcing the engine to work harder to produce the same level of power. This added strain often results in higher fuel consumption. For fleets, even small drops in fuel-efficiency can add up to significant costs over time. Regular oil changes help maintain proper lubrication, allowing engines to run more smoothly and efficiently, which can translate into noticeable fuel savings across the entire fleet. Reduce the Risk of Costly Breakdowns Skipping or delaying oil changes increases the risk of overheating, sludge buildup, and internal engine damage. These issues can lead to unexpected breakdowns that disrupt schedules and require costly repairs. Preventive maintenance, including timely oil changes, helps identify potential problems early and reduces the likelihood of catastrophic engine failure. This keeps vehicles on the road and helps prevent downtime.
