Engine/Transmission (1994 - 1998) Poor mileage

[cumminsnbabes]

My mileage for the past month has been 14-15 mpg. Within that month I put in a 0 plate full forward and 285/75/R16 Dayton Timberline MT tires. Before those mods I was getting 17-18 mpg. Also, the K&N hasn't been cleaned in 8 months and the fuel filter was changed over a year ago. Haven't noticed any loss in power, but I've been driving VERY conservative. Any input would be appreciated.

You may have got the winter blend fuel.
