Awful Mileage

[danewilson77]

Just for posterity's sake, throw that K&N in the trash can with gusto.

I've had two ZHPs and both had idle quality and throttle response issues. Both had K&N drop ins. Both drop ins were trashed for paper, both MAFs cleaned, both run night and day better.

Depending on where you fueled up you could be suffering from a winter blend as well. I know metro atlanta switches between summer and winter blends and mileage always takes a hit.

Other points I would've raised (rack, skis, weight in the car) have all been dead horsed. Amp draw from headlights would be within the noise.

My progression was.....K&N Oiled Drop in.....to AFE oiled.....to AFE Dry. I am very happy. CAI with dry filter is perfect for me. Lifetime filter as well. Thanks KG

So just reading this thread and some others, here's my list of imaginary ways mileage could be worse in cold weather
[*]Engine takes longer to warm up and runs rich when cold (from BP)

Just out of curiosity, why do you think this point is imaginary? Perhaps I misunderstood you.

What do you all think of the purlator filters compared to the mann filter? The local auto store only carries purlator filters.

Must. use. Mann.

Purelator is probably fine in all honesty. I just don't chance it. I could overnight one (Mann) to you tomorrow?

You have a PM sir!

[danewilson77]

So do you!

Epic win.

Will ship tomorrow Hokie. If it doesn't break the bank...I will go with overnight.....

Winter blend gas drops my gas mileage by roughly 10%. OP it could be many different things as mentioned in previous posts. Would be interested to see what the culprit is.
