What does Lexus recommend for the engine break-in period?
The engine of your new Lexus vehicle is made with industry-leading precision and quality. As a result, the break-in procedures listed in the Owner's Manual for a brand-new Lexus are optional. While following these procedures may help to optimize engine performance and engine longevity over the life of the engine, these potential benefits are marginal compared to the benefits that result from ensuring that recommended maintenance is performed as scheduled.
