FAQs
What Areas Do You Serve?
We are based at 631 Kentucky Ave., Woodland, California 95695, near Interstate 5. In addition to Woodland, California, we proudly serve Sacramento, California, Fairfield, California, and San Francisco, California.
How Often Should I Change My Truck’s Oil?
Oil change intervals depend on the engine, usage, and oil type. Heavy-duty trucks typically require more frequent changes due to high loads and long operating hours, so regular inspections are important to maintain proper lubrication.
What Happens If You Don’t Change The Oil In Your Truck?
Old or contaminated oil loses its ability to lubricate and cool engine components. This can lead to increased friction, overheating, and eventually serious engine damage or failure if not addressed.
