Replying to: geeteeeye (Jun 18, 2007 2:34 pm) That is a complete aberration. I drive my GTI hard at 4-5000 rpm every day. I get 25-26 mpg with manual transmission mixed city and highway. EPA figures are 32 highway and 24 city. The FSI technology used in the GTI makes for the most fuel efficient engines in present time. It is the most fuel efficient car in its segment

VW recommends premium-grade fuel." Check out this AutoChannel.com road test of the GTI: http://www.theautochannel.com/news/2006/07/07/014005.html Fuel Requirement 91 octane unleaded premium gasoline And from VW's own technical specifications: http://media.vw.com/press_files/text/GTIT.S..pdf Check the Fuel Requirement section: It will say 95 RON Premium for Maximum Performance & 91 RON for a slight reduction in performance. Most VW mechanics I've talked to said that using anything other than premium (91 RON or above) in a forced-induction engine is asking for trouble ($$$$)...

Replying to: 600kgolfgt (Jun 20, 2007 12:50 pm) Also, VW is technically saying that Mid Grade (91 (R+M)/2, not 91 RON) is the recommendation. Lastly, if you crunch the numbers, you're still saving money by using 87 octane even if you get lower gas mileage using 87 octane. You'll have to get better than 2 mpg better using 93 octane gas to break even.

I have a 2007 GTI base 6 speed manual that both I and the wifey adore its really a great car. Anyhow at apprx 3000 miles while driving on the interstate the CEL came on and came on and off intermittently until the car began to "Buck and Jerk" and try to die on us while driving. I had scheduled several appointments for the car prior to the bucking and jerking and was told that maybe the gas filler cap wasnt tight emough etc..etc.. and I did not get the chane to actually drop the car off until it began to truly fail us. So I dropped it off 2 weeks ago and after 5 days in the shop they told me the car had a bad fuel pump or one that did not generate enough pressure? They replaced it and I got the car back. two days later the CEL came back on and I called the dealership service dept and they had me drop thye car back off. That was 10 days ago and so far I have been told that they have been in contact with the VW engineers and trying to pinpoint the problem or find the correct fule delivery part to correct the issue. Has anyone else had these types of issues with their new GTI's? I love the car and they gave me a rental car (very creepy Dodge Caliber)but I have some concerns about the lenght of time that they have had the car. Its a lease so i'm not so concerned about the long term I just want my car back Fixed properly!
