Fuel economy can vary for a number of reasons. Like the others have mentioned, city and highway make a difference. Check your tire pressure too, under or over inflated tires can effect the mileage, also, I have seen a lot of people here keep there cars idling for extended periods. If you are checking this only for the last 90 km, 5 minutes of idling will drop at least .2 on your economy. Check it a couple times over 500km intervals.

For an engineer, put it on B4 sheet of paper with the electrical wiring to the headlight and all the dimensions possible and then put down the steps to sand the headlight.. he will figure out how to do it. 😂

Dont be scared to try doing it your self. I have done it on a few of my cars of the years. 1. Wet sand with 2000 grit sand paper till all the discoloration is gone. Let dry for 10 minutes or start doing the other side. 2. Once dry, wet sand with 3000 grit or higher to get the smooth glossy finish. Let dry for 15 mins. 3. Wax with any car wax and maintain it. The next time u notice it getting yellow, go straight to the 3000 grit sandpaper and buff immediately and wax. We have the long weekend coming up. Give it a shot. All the best.

Congrats @Ale Vallecchi

Congrats @Thomas J

Congrats @Mikhail Lukichev. Well deserved.

Thanks @Emmanuel @Frederic @Javier M for the nice drive. I did not know what to expect on an intermediate drive but in a few minutes realized why newbie and fewbie drives are called relaxing drives😄. Honestly I would not have dared to try a drive like this in the Grand Cherokee, but knowing the carnity family always put safety first and are always willing to train and help gave me the confidence to give it a shot. Thanks to @Emmanuel @Frederic and @Javier M for the patience they had with me. I know I slowed you'll down quite a bit. Being the first drive at this level, I was not really sure how the JGC would handle so didnt want to push to much till I got a feel of it. Pretty sure @Emmanuel would have gone for a 100km drive instead of 60 km had I kept up. 😀 @Javier M thanks for the 2 recoveries when I crested myself. i still need to get the straight up straight down sorted out, always think I am going to nose dive on one of those so end up taking my foot of tha gas to early. Thanks again guys for the wonderful drive. Looking forward to the next one. Not to forget @Rahimdad and @Gaurav, thanks for all time and effort you guys put into training us and building our confidence.

Congrats @Halit Mert Issever.
