I was going through receipts and paperwork that the previous owner left me with, and nocticed that there was a purchased of a Prolong Car Kit. I would assume that he bought it for the "Seven". Anyhow, my car has about 110k and still pulls strong...bone stock. According to the receipt the Prolong Car Kit was purchased six months prior to me purchasing the car. I was just curious has to anyone who might have use the Prolong Kit and there experiences with the product. It is safe to use on a rotary engine? Any feedback would be great. Thanks! in advance.

 

I've only used Prolong lube on the pulleys and such. I almost bought the Z-Max, but then I couldn't have bought pizza and a movie.

There are no pistons or cylinder walls to lubricate, so the question is: Would it be benficial to the Apex seal?

If you beleive the infomercials, Z-Max would be the best of those lubricants.

I think he was just buying insurance or rather "reassurance" to make sure the car didn't break down while he was selling it.
