I have a 1996 Honda Accord EX with 229,000 miles on it. I noticed a loss of power gradually over time. I was in Napa two weeks ago, and asked the clerk what she suggested for cleaning the fuel injectors. She said hands down the lucas oil product would be the only thing she would sell if she had her way. I bot it (skeptically), and filled my gas tank, and put a bottle in the tank. I am still using the same tanks, and would normally have had to fill my tank again. So I do not yet know how many more miles/gallon, but the "merging" power has noticeably increase, also. Your product has breathed new life into my old car... thank you. I am hoping to go to 500,000 miles now.
