I added zMax to my 2008 BMW 128i to see if it would quiet a noisy lifter and it did! This is a low mileage used car and with the BMW long intervals for oil changes, no telling how few oil changes this car has had. zMax seems to have done the trick and the slight tapping noise is now gone. The engine now purrs like it should. Gas mileage also improved significantly, but not sure if that is just temporary due to better driving habits. I'm adding xMax to my other cars to see if I get the same positive benefits. Not sure I'll continue at the recommended intervals due to the price, but do plan to continue to use periodically.

Comments about Z-Max Engine and Fuel Micro-Lubricant:

It seems to increase fuel milage for at least a few thousand miles at least in my truck 6.4 hemi ram 2500 but in my wife's Jeep it did not seem to do anything so it may be better in some vehicles than others I don't know just my experience.

For both your engine and fuel zMAX will help maintain your engine and extend engine life.

    • Q:

      Will zMAX oil treatment quiet lifters down if they're making a slight noise when cold
      Asked on 11/14/2016 by Jack from Hilton Head island

      1 answer

      • CUSTOMER CARE

        A:

        Yes, Jack! Z-Max Engine and Fuel Micro-Lubricant - Part No. 51-011 has been known to quiet noisy lifters as it is always present and able to provide lubrication before the splash lubrication from your oil is present (like at startup).

    • Q:

      how often do you add zmax to your engine oil ? every oil change?
      Asked on 5/6/2014 by Randy from United States

      1 answer

      • CUSTOMER CARE

        A:

        Hi Randy, good question! Pour zMAX Fuel Formula (12oz.) in the fuel system with at least 1/2 tank of gas or diesel fuel. Pour zMAX Engine Formula(12oz.) into your crankcase. Works with all engine oils (synthetic, multi-grade or mono-grade including diesels). zMAX does not replace your regular oil. zMAX will not overfill your normal oil level, because it soaks into metal. Start engine and bring to operating temperatures after installation. Recommended every 6 months or 6,000 miles, whichever comes first.

    • Q:

      I have a 2 cycle gas engine in my golf cart. I believe the piston and rings are glazed over. Do you have a product that will remove this problem and improve the compression? Thank You.

      Asked on 3/25/2014 by Curt from Idaho

      1 answer

      • CUSTOMER CARE

        A:

        I'm happy to help, Curt! Z-Max does make a small engine formula that may help. I also know that Sea Foam is a very popular treatment that claims to remove varnish, carbon and gum from the engine and is made with 100% petroleum products. The results of any engine treatment may vary and cannot be a guaranteed fix. Even after treatment you may still find it necessary to disassemble the parts and clean them separately.

    • Q:

      I have heard that the Z-Max engine treatment and the fuel traetment are exactly the same and can be used interchangeably (i.e., the fuel treatment can be used in the oil and the engine treatment can be used in the fuel system). Is that correct?
