What product have you purchased?
We are waiting...
Thanks, Jim
I've had a great experience so far. However this is a mpg test which means nothing. I'm not equipped to do a carbon mass balance or a specific fuel consumption.
Edit: Product used FPC - 0.5
(the $24 box)
My 1995 Mercury Grand Marquis baseline was
253, 260, 254 miles per tank
Treated with FPC
311, 301, 304
I still have 9 bottles to use so I'll update this as I go. Again, this is just a MPG test I'm not calculating anything. I do believe I drive as crazy one day as I do the day before, but I can't say that with 100% certainty.
The mercury has never had an additive in it before FPC.

I still don't understand how you think you'll only be saving 1.7%. The RP-503 you have to understand is a test to see if something is "snake oil and mouse milk", not a test to see the maximum improvement on an in service engine, but rather the minimum.

I still don't dismiss every other test on the website. Every test on their website has a copyright page, but I think that is just because it is on their website. I hold ESDC on the same field as SWRI. Also, the RP-503 looks like a hugely expensive test $US 240,000! I'd say that's weeds out the fakes like organic chemistry did back at my university hahaha.
