New 330i ZHP getting lousy mileage
I was getting between 360 and 450+ per tank on my manual 325Ci. The manual 330i with 1700 miles is lucky to get 300 miles per tank at 90% highway
I broke in both engines the same way, and I drive the same way as I did in the 325. I have no performance mods. At this rate I should have just got an S4.
I thought it might be winter fuel related, but my 325 with 52K was doing fine in Dec. And it's not a small engine vs. big engine b/c the 330i EPA range is 21/30 mpg. Unless the EPA numbers are grossly inaccurate as in the hybrid Toyotas, I'm at a loss.
Is this 39.2 DME related Anyone else getting 300 miles or less from their ZHP?
