Not to be harsh, but there's NO additive on the market that been proven to do even one bit of good. Jaguar specifically instructs NOT to use any additives in the oil or fuel for very good reason. There is no control over how it modifies the fluid it's being added to. Just as likely to do harm as do nothing.
You obviously did not read my post stating the product increased the MPG on my wife's Suzuki Swift. However I do understand there is a lot of snake oil out there and temper that with experience of the real world, not just from what I read or am told.

I read that post. It's precisely what prompted me to reply. If the common sense aspect of my statement didn't sink in and you prefer to believe in unfounded miracles, then please have at it.

If this product could actually increase mileage by almost 3%- don't you think the car industry would be all over it?

It's common to see a variation of a few percentage in mpg from one tank to another without the driver having made any changes at all.

Just out of curiosity, I dug a little further to lean some more about the ZX-1 product and in particular why the manufacturer doesn't consider it an oil 'additive'. Turns out that the active components are intended to form a coating on metal engine surfaces and thereby reduce friction. This compound is suspended in petroleum oil to simply adding it to the engine.

The following analysis about it's properties popped up:

GT-R Register - Nissan Skyline and GTR Owners Club forum - View Single Post - Extralube ZX1

which would stop me from using it right there.

Further digging indicates that modern oils have more than sufficient anti friction additives (commonly ZDDP) which are more effective than any of the snake oil products described in the link. There is further concern that the aftermarket products may be incompatible with many engine oils and their own additive package.

Buyer beware.
