I put it in my 77 Chev 4wd PU. Result? Zero mileage increase. I was desperate for any help, as the beast gets only about 9-10mpg in normal (non-4wd) driving. The mechanic gave me my money back, though, so all was not lost. He said that he had talked lots of his customers into trying it after his own success, and inexplicably it worked for a small percentage of cars, but on the whole was a total failure. Still waiting for a miracle mpg booster, --peter
