Using thicker oil will help stop lifter noise. However, it will not solve the underlying problem. This is especially if the noise is caused by wear and tear, bent pushrod, or carbon deposits and debris. You’ll need to check the lifters first to diagnose and fix the problem.

How do I free up my lifters?

  • Run an engine detergent in your gasoline, and use a higher-octane gas. Often, fuel system cleaners or detergents can free up engine debris and stop a valve lifter from ticking.
  • Use an engine flush, and then change your oil. Engine flush products are available at many auto parts stores.
  • Is there an additive to quiet noisy lifters?

    The best additive to quiet engine noise is Archoil AR9100 Oil Additive (16oz) for All Vehicles. It's a reliable friction modifier designed for diesel and gasoline engines, hydraulics, gearboxes, power steering systems, and differentials.

    Why is my car ticking when I accelerate?

    In most cases the cause is either due to oil pressure, exhaust leaks, spark plugs, or the valvetrain. All these problems arise when accelerating as the sounds are amplified when the engine RPM's increase. Fixing these issues won't cost you much, but make sure to figure out the problem as soon as possible!
