Honestly, I used to be so strict about following my car's manual for oil changes and servicing. Thought I was doing everything right until last summer when my engine overheated badly on SZR. Cost me a fortune in repairs. The mechanic basically told me those international service intervals are useless in our heat. He showed me how my fluids had completely broken down. I started researching proper maintenance for our climate and found a detailed guide that perfectly explained what happened to my car and what I should have been doing differently with my coolant, oil, and transmission fluid. I follow a much stricter schedule now based on that advice. Anyone else had to learn this lesson the hard way?
