OK I thought I'd put up the pic of the Lucas fuel treatment I've mentioned as something I use along w/ the MPG Remedy. This is to help those trying to figure out the MPG R thing who don't know what the Lucas is. The MPG R thread is very long now, this might help save some time for somebody.
Lucas Upper Cylinder Lubricant w/ Injector cleaners is not an integral part of MPG R. I just decided to use it along w/ the Remedy, added separately not mixed in jar, and both times I have the mileage has been dramatic to say the least. Available at lots of Auto Parts stores and truck stops. in 5.5 Oz, Qt and gallon sizes. Like a light oil, and keep the bottle upright and secure w/ a rag around it if carried in vehicle. I've used it for years.
