did this cause the problem? coincidence in two vehicles having he same trouble after using this product??? i put some in the tank of my 2004 kawasaki enduro and shortly thereafter it runs like it is missing, that there is a fuel starvation problem. i added it also to my 1992 astro van and shortly thereafter the same problem, it will run as if missing, as if fuel starved. same feeling when there is a clogged fuel filter. not sure this product caused it, but one vehicle, then the other??? i will not risk it again.

Product with a good reputation frequently referenced in auto restoration publications. Using it my car which has had limited driving for the past 6 months without problems. Dispensing small quantities (1 oz increments) and adding directly to the gas tank from the container is very easy; only wish it were as easy to measure and dispense larger quantities (4 oz increments or more) from the container.

Great stuff,just add to gas and it stays fresh!!This is a must for people who dont use up their gas very quick.
