That caught me attention is that, if there is any leak or something, i should be able to smell it and see it on the ground right? I have not see or smell any gas leak at this point, so i guess it is fine right? I just resesal the gas cap carefully and turn the cap few more times after i heard the click. My gas run fine at this point, between 22 to 25 mpg, I guess maybe just the cap need to be tier.
