I've been going back and forth with my mechanic about this. I follow my car's manual religiously for service intervals, but he keeps telling me I need to bring it in more frequently. I thought he was just trying to get more money from me, but he explained that where I drive matters as much as how many kilometers I do. I work in a busy commercial area in Sharjah, lots of stop-start traffic, short trips, and dusty conditions. He sent me a link and said Click here for detailsclick here for details about how driving in active commercial zones affects vehicles. The article explained that engines in short-trip city driving never fully warm up, which contaminates oil faster. It also covered how constant braking in traffic wears pads down much quicker and how dust from industrial areas clogs air filters prematurely. Now I understand my mechanic wasn't trying to upsell me, he was being realistic about my driving conditions. Anyone else had this experience where your real-world driving doesn't match the manual?
