I just bought a brand new BMW M4 and I want to make sure I properly break in the engine. What are the steps I should follow and how long should I wait before driving at higher speeds?
ReplyIt's important to take care of your engine during the break-in period to ensure optimal performance and longevity. First, avoid driving at constant speeds and instead vary your speeds during the first 1,200 miles. Also, keep the engine's RPM below 4,000 and avoid hard acceleration. Wait at least 1,200 miles before driving at higher speeds.
