Why Are Oil Tests Important?
Changing the oil in big trucks and commercial vehicles is an expensive, but necessary, part of keeping your vehicles going. You don’t want to wait until it’s too late to change your oil, but changing it too early can be a waste of time and money. Having your oil tested regularly helps us to hone in on exactly how often your oil needs to be changed, to optimize reliability and efficiency.
Your engine has trouble starting - is the starter bad?

When a vehicle has trouble starting, many people initially blame the starter. What is the starter, and how do you know if yours has called it quits? At K & K Automotive in Frederick, MD, we want to keep you informed and telling you what to look for will prevent further damage when issues arise. The starter is essentially just an electric motor; a gear at the end of that electric motor engages the flywheel, which turns the engine over, allowing it to start. How do you know if yours is failing?
