First let me apologize for the rampant spam that this forum has experienced for the past several weeks. Since the C-MAX is discontinued, we essentially left the site up and running based on the previous moderator's wishes to upkeep it. That obviously didn't happen. I have cleaned up the site earlier today and rooted up all suspected members. I also made it tougher for spammers to register and I'll keep an eye on the site. If anyone would like to help moderate the site, please let me know. Bill

Most aren't going to drive their C-Max 300 k miles and likely not even 120 k miles. But like I said, go for the savings with an oiled filter if one is going to keep the vehicle. Sorry, but this mileage claim is hard to believe? So, a 5 mpg improvement on a 15 - 25 mpg truck would be a 20 - 33 % increase do to replacing an OEM air filter with another air filter? Second, modern engines operate in closed loop operation to optimize FE / emissions based on sensor data input. There's simply no way one could achieve a 20 - 30% FE improvement by replacing an OEM air filter on any modern vehicle unless one illegally modded their vehicle (like removing emissions equipment and re-tuned) and then the FE improvement is not due solely to the air filter.
