Manufacturers, urged by EPA emissions standards, suggest longer oil change intervals—6,000 to 10,000 miles. The goal? Less oil waste and fewer emissions. But for small-displacement turbo engines, these intervals can be misleading. Why? These engines often run hotter, which can break down oil faster, leading to sludge and engine wear. So, more frequent oil changes—despite EPA guidelines—can be crucial to keep these engines healthy. Let’s understand the obvious, newer vehicles have smaller displacement engines and turbos, right there any reasonable mechanic would tell you that higher frequency oil changes would be mandatory. Manufacturers also state that better engine tolerances and improved oil performance are why longer stretches are being used. MISLEADING, no engine improvement and oil improvement can help with engine oil getting polluted over time !
