Happens all the time with me mate, actually Im a freak when it comes to cars.......after every re-fill, the instant I start up my ride I am able to judge the petrol, whether or not it
s good fuel or bad fuel, and sure enough the acceleration decreases, mileage decreases an tons of other issues arise, these days fuel coming in is very bad, trust me..........store your car for a while an I guarantee it will give you problems once you start it again........................btw how old is your car?? Although let Ahmad pai come in, he is more technically sound than me on such issues.......though just for the sake of durability I have an 07 model thats never been tuned, done 100k on it, now though after eid I
m taking it in for it`s very first tune up..........:-#........just a testament that hondas are tough too!
