Four miles per gallon? I'd be interested in seeing your error analysis on that one. I bet the OEMs could get considerable CAFE credits by pushing this product. Yet, they don't. I wonder why that is.
Because they realize an "upper cylinder lubricant" isn't going to change performance in an engine with no significant wear or corrosion.
Try a car with 130k miles or more. If it helps valves seat and lubes things up it is going to help performance and thus efficiency. It's really more a comment on my engine's health that a little lubrication helps it out that much more than it is a testament to their product.

I miss Deep Space Nine, thanks for reminding me of it lol
