Will this product help with refreshing the seals in older cars (2009 Genesis, 2008 Jetta). Neither are high performance but looking to keep them goin

Will this refresh seals? Most seal "improvement" products contain chemicals to "swell" seals, to stop leaks temporarily, and often the leaks will come back worse than ever after 10K miles or so, or cause new leaks. Its my understanding that this product is for much older cars, which were depending on additional lubricity and film strength, in the older oils. I use this in my 1952 MG TD sports car. I would recommend replacing your leaking seal, rather than finding a temporary solution.

Is this pure zddp or is it diluted in another fluid?

REV X Zinc ZDDP Oil Treatment is blended with a extremely small amount of oil to make sure the product stays in suspension. Thanks for asking such a great question.

How much can i add to one quart of oil?

According to REV-X website one 2fl.oz bottle can be added to six quarts of motor oil for maximum protection. One fluid oz is 29.5735x2(bottles)=59.147ml(cm3). So, one 2oz REV-X ZDDP bottle contain 59.147ml(cm3) divided by six equal 9.858ml(cm3). You need to add to one quart of oil 9.858 milliliters (cm3) of REV-X ZDDP.

Works excellent. Be aware you only need 1/2 bottle after break in

Zinc (ZDDP) IS CRUCIAL for pre catalytic converter engines with flat tappet cams. It wasn't widely known when manufacturers took this out of motor oils and many of my motor head friends were experiencing cam and lifter failure even with brand new cams. PLEASE NOTE 1fl oz is recommended for oil AFTER initial break in so be aware of this, and grateful you have enough for twice as many oil changes.
