FAQ

  • Can I clean a fuel filter?

    Fuel filters are generally not washable. Most engines are equipped with disposable non-washable paper filter elements. Fuel filters are changed together when the oil is changed. They can not be washed clean, since there will be impurities left.

  • What happens if air filter is too dirty?

    If your air filter gets too dirty or clogged, your engine won't be able to suck enough air into the combustion chambers.  The engine of the air filter will then can not get enough clear air (i.e., too much gas and not enough air). If you really neglect the air filter for a long time, your car may stop running completely.

  • Is it OK to use the same oil filter twice?

    Yes, it's perfectly safe to use either type of filter with either type of oil. However, if you practice extended drain intervals using synthetic oil, a conventional oil filter may not offer the required service life, meaning you'll have to change it in the middle of the oil drain interval, which is inconvenient.

  • How long does an air filter last?

    Check your owner's manual; it should tell you when your air filter should be replaced. This is generally every 12,000 to 15,000 miles, depending on your vehicle. If you have driven more than that since the last time you replaced the air filter, it's probably time to get the air filter changed.

  • Is it bad to change oil without changing oil filter?

    Can I change oil without changing the filter? Yes, you can, but it's not usually really a good idea. This oil doesn't drain due to the anti-drain-back valve on the filter. If you don't change your filter, this old, dirty oil will become mixed with your fresh oil.

  • What is the difference between an air filter and an air filter?

    Air cleaners filter the air (HEPA air cleaners for instance) while air purifiers sanitize the air by emitting negative ions, ozone, utilizing heat (Airfree air purifiers), or with UV or UVC lamps. Air cleaner strengths: filtering the air and collects dust, especially the larger dust (mostly dead skin) and pet dander.

  • What are signs of bad air filter?

    Common Signs of a Dirty Air Filter: Reduced fuel economy; Misfiring engine; Unusual engine sounds; Check Engine Light comes on; Air filter appears dirty; Reduced horsepower; Black sooty smoke or flames exiting the exhaust; The smell of gasoline when starting the car.

  • What happens if we do not change oil filter?

    Oil filters trap dirt, sludge, metal particles, and other impurities in your motor oil. That's to keep the oil as clean and pure as possible, which allows it to do its best job of lubricating the inner parts of your engine. Without a good filter, the gunk could damage internal engine parts, raise engine operating temperatures through increased friction and shorten the life of your engine.


    Most people change their oil according to their vehicle's manufacturer recommendations, found in the owner's manual. That can be 5,000 miles, 7,500 miles, or some other number. You'll find people who are fanatics about changing their oil every 3,000 miles — to make sure it's the cleanest, purest, and best it can be.


    But a lot of owners and mechanics —many of them the same people who would never go past 3,000 miles per oil change — also would never dream of doing an oil change without also changing the filter. Their reasoning: Why pass brand-new, clean oil through a filter that's already carrying gunk from the old, dirty oil?

  • Does engine air filter affect gas mileage?

    If the air filter is dirty, it passes less air into the engine. It can impact your gas mileage – by as much as 10 % – and it will also affect the engine performance. Your engine needs oxygen for fuel to combust.

  • Should you pre-fill an oil filter?

    An old question is whether we should pre-fill the new oil filter before installing it. Answer: Pre-filing makes the process easier if you have a large, heavy-duct truck, but if just a small light car,  it is not necessary.
