Replying to: finfan39 (Mar 15, 2008 2:46 pm) I have a 07 Z4 Coupe, my wife has an 05 Mini, and we both run hi-test gas. At today's prices it just isn't that much more expensive here in SC. However, when Katrina cut off our gas supplies, all we could get for a week or so was regular gas, which my wife ran successfully in her Mini with no problems. While hi-test is recommended by the factory on both models, their ECM's have the capability of adjusting the timing and other engine related functions to run on lower octane gas without any problems.   Some suggests that BMW recommends premium gas simply to re-enforce the "premium car" image, but I really can't say...
#10 of 13 showing different mileage by z4red Jun 27, 2008 (6:16 pm)
Hello New to this site. I have 2005 z4. I have a silly questions. I noticed my MPG dropping for e.g. it use to 27 show mpg then it drops to 25 & now 22.8. I am not driving any differently. I always used 93 high octane. Am i looking at it incorrectly or should take it to dealership. Another questions show often should I do the oil change. I call BMW dealership since it is more than 4 months & they say it is not due for another 3 months. Sorry about the ignorant questions P.S. it is my dream car

#12 of 13 Z4 Mileage by z4poppy Nov 30, 2008 (5:40 pm)
I have a 2006 3.0i. I get around 30 on the road. I have checked the last three tanks manually and my computer mileage is reading slightly lower than actual mileage- from .4 to .8 below figuring by hand. If I really take it very easy, I can increase mileage by about 1 mile per gallon. I use only premium fuel.
