I put 91 octane it over here. I buy gas on base so it's $3.19 a gallon. I bought offbase once and it cost me 80 euro for 3/4 of a tank. The H3 is pretty big compared to the German cars, but there are quite a few big cars on base. My German neighbor accross the street from me called the cops on me for using my remote start. Lol.

 

Similar problems with my passenger side floor was soaked with water.

The dealer mention something about the waterdrain line from the roof was detached and was draining into the cabin.

Hope this helps

 

Guys don't waste your money at the dealerships. I took my h3 and they quoted me close to a $1000 to replace all the rubbers. I took my h3 to a collusion center and they readjusted the doors for $75. No more leaks and total time 20 minutes

 

Thanks for informing these guys FROM 5 YEARS AGO what to do. Please look at the date of the last post in a thread before posting. https://www.hummerforums.com/forum/n...bumping-23220/
