Re: Post your experiences with the TSB 18-012-11
On mine, the EVIC was giving better gas mileage right after the TSB was applied, but in hindsight it was just due to the type of driving I was doing at that time.
Checking the one and a half tanks since the TSB, by calculator rather than EVIC, the mileage seems to be the same (i.e. within normal variance). So similar that now that warmer weather is coming, it will affect mileage to a greater extent than the TSB so it will be hard to sort out any difference.
The better performance is worth any minor mileage affect, if any, for me anyway.
