Me on the contary I have used additive cleaner and cetane booster I hv had the oxygen sensor go bad and the EGR issue after that car has been running great until I stopped using both items and then i had not only the SES go on but also go on LIMP Mode I turned car off limp mode went off, and I ran the 1/2 race twice at 150 mph after that the car purrred at me, ever since that im getting anywhere from 21-23 mpg city and 36-42 mpg highway and trust ME I drive her like a two cent whore.
