Engine break-in procedures have long been divided between two camps. One camp is adamant that you baby the engine for the first 1,000 miles, letting it break in slowly. The other camp suggests you drive it like you stole it, showing the engine no mercy. But which method is the correct one? According to SavageGeese, the answer could be both.
The best way to break in an engine depends on the automaker and the engine type. Engines that are mass-produced for vehicles like the Honda CR-V or Hyundai Sonata require little to no break-in. They are designed for people to get in their car and go. Handbuilt engines or engines with exacting tolerances for high-performance cars like a Ferrari or Porsche benefit from some form of a break-in process.
