Subject: recent poor mpg
From: Kirk Werner <Kirk Werner.org>
After fuelling up recently and finding that my mpg was more horrendous than
normal, I decided to do my seasonal K&N air filter maintenance my truck
(v-10). When I opened the housing and removed the cartidge, I swear that a
maple leaf came out with the filter. Now before you laugh- or before I laugh
at myself- someone tell me...on a V-10, can something as large as a leaf get
into the air intake tube and become stuck in the filter housing? Obviously
bugs and other smaller debris/grit can because I cleaned that sort of stuff
out as well, but a big leaf? At any rate, the leaf may have only recently
gotten lodged in there. And coincidentally or not(?) I noticed that my last
tank of gas yielded the poorest mpg I've ever clocked, by about 3mpg. I
know engines are basically big air pumps, so if the flow is restricted,
performance is compromised. I guess I'll know if the leaf was the culprit
when I fill up next and calculate my mileage.
OK, so go ahead and laugh if warranted.
Anyone else with a gasser had a dramatic and sudden decline in their mpg?
I've got 13K miles on my engine, and it's had the standard scheduled
maintenance, so I'm looking for possible clues as to the recent poor mpg.
Engine runs smooth and seems normal. Driving habits have not changed.
Temperatures have been mild here in the Pacific NW...ideas?

3 MPG? Man... wondering, did you try a **key locking** gas cap? That might
