mechanic holding oil stick over vehicle 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.

Oil Condition is a Good Read of Overall Engine Condition - Your oil says a lot about how your engine is running, and what problems may arise in the future. By analyzing the amount of carbon, coolant, metal, etc. that is found in your oil, issues can be caught and monitored before they become bigger ones. Signs of leaking head gaskets, worn rings, and so on can be found in oil samples that technicians can obtain from oil tests. Even traces of the types of metal found in oil can identify bearings or other parts specifically that are wearing too fast.

Peace of Mind - Regularly analyzing oil keeps you on top of things. You know exactly where your engine stands, and whether or not it’s in good running condition, and what to watch out for. This type of advanced monitoring gives you time to anticipate future issues or work that may be required, so nothing catches you off guard.
