Nice drive around Fossil Rock yesterday, great fun and every drive has something to teach. The drive progressed smoothly thanks to @Gaurav and @J J as second lead, with very interesting straight ups straigh downs on pretty steep dunes. Sand in the beginning was not too soft and actually felt firmer than I expected. Convoy with @Veedooshee, @Leo Francis, @Carlos Fernandez proceeded smoothly to the base of Fossil Rock, where I got stuck while climbing up. I am not sure why, car did not get the power even at full throttle, same happened to me once at Pink Rock with revs going down despite me accelerating full throttle. Also in that case heat gauge was slightly higher than normal, not in the critical area, but some 25% above usual "Sheikh Zayed road reading": could the engine cut a bit of power if temperature increases beyond a given limit? What do experts think? Anyway, I managed to come out from the refusal myself, following the suggestions @Rahimdad gave me on my very first drive, steer left and right, a bit of throttle, low gear and very important "sometimes is easier to get unstuck going backwards"... you never think about this as you naturally "look forward", but sometimes a step back is more helpful than trying to move ahead with no results! Out of that, though, I got into a pretty nasty spot slightly off the track, with very soft sand and a little dune just behind me. Car overheated seriously, so @Gaurav suggested to stop for some minutes and helped me cooling it down with water. When temperature went down to normal, I managed to get out from the situation and climb up Fossil Rock successfully. The final part of the drive was quite interesting, taking us to the end following the suggestions of @J J and @Gaurav guiding us down the slope. Overall a very enjoyable drive, always something to learn out in the desert, this time a very basic lesson for me... 3 liters of water might not be enough, especially if you need some to cool down an overheated engine! Next time, a part from drinking water, I will make sure to take some for "engine use"! Thanks to the above mentioned drivers and to @Gaurav for having led the troop! Good luck to @Shamil to get his car fixed soon. Pictures as usual in the drive gallery.
