The engine is the most important component in your car. If it fails, not only does your car not function, but it’ll be costly to repair. While routine maintenance and oil changes will keep your engine running in good shape, you’ll also want to consider using an engine flush from time to time. This way, your engine stays as clean as can be, helping to run for hundreds of thousands of miles.
So what exactly does engine flush do? To explain this, we take a look at LUBEGARD’s explanation for what’s going on when your engine is operating. A high quality oil filter is designed to remove contaminants up to 25 microns, but the most dangerous contaminants to your engine are between 5 to 20 microns. That means those contaminants are larger than the finest tolerances in your engine, but they’re also too small for your oil filter to remove. According to LUBEGARD, that causes approximately 60% of the wear on your engine. If you’re not flushing those harmful contaminants out from time to time, sludge, tar, varnish, and other wear metals can continue to circulate within your engine.
As a result, those contaminants will cause excess wear and tear on your engine, resulting in higher operating temperatures and reduced lubrication. If an engine becomes heavily contaminated, even an oil change isn’t sufficient to remove those contaminants. That’s where engine flushes come in—helping you flush all that sludge, tar, varnish, and other contaminants from your motor.
In addition, engine flushes are great to use after an extended interval in between oil changes, or if you just purchased a used vehicle and don’t know its service history.
