Just a quick update. We now have 2 fillups since adding the CeraTec to the engine and transmission. So far, the results look promising. Actually, the last fillup was a new personal best! It came out to 65.9 mpg. Previous to that, the best was 63.6 mpg, back in April.
I haven't done the math yet, to see if the FE increase is enough to cover the cost of the additive. That can wait until I get more FE data.
Also, we have another tropical storm (possibly strengthening to a hurricane) coming our way. So the projects are on hold... again.
