Why is it so important to use the correct oil in when the oil is changed in your car or trucks engine? Today’s vehicles have requirements for low emissions, high fuel mileage, and customers want high horsepower. To meet these requirements modern engines are much more complicated, with internal systems such as variable valve timing. There are actuators inside the engine that are operated by engine oil based on oil pressure. If the correct grade or viscosity of oil is not used then there can be a problem with how the engine performs and there could be a check engine light. We have plenty of examples of fixing a check engine light or an engine driveability problem simply by changing to the correct oil.
There is also the possibility that the vehicle warranty could be affected if the correct oil is not used. For these reasons, at G&G Auto Repair we always look up the manufacturers required oil specification for every vehicle when we change the oil, and we only use an oil that we verify meets that specification. We use oil from a variety of sources because even popular brands of synthetic oil don’t meet the specifications of every manufacturer. Whether you have your oil changed here or at another repair facility it’s important that the correct oil is used in your vehicles engine.
