Dalen Spies uses Lucas Fuel Treatment for 77 Olds Cutlass Supreme

I would like to thank everyone at Lucas Oil for making such a high quality oil products. I had a '77 Olds Cutlass Supreme that had 96,000 miles on it and I would drive it 20 miles round trup to work and back Mon.-Fri. I would have to fill it up once a week but after I started to use your injector cleaner in it I was able to go every two weels before I had to put any gas in it and I was even driving longer distances then I normally did. so now I use it in everything. Thanks again for a wonderful product.
