monarch Posted December 1, 2005 Share Posted December 1, 2005 IF you register your car at lexus.com you'll have access to a huge FAQ that Lexus put together for owners. Here's what the FAQ says about new car breakin: Engine Break-In Period Question: What does Lexus recommend for the engine break-in period? Answer: "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." As you can see, Lexus is saying that the benefits of a careful breakin are trivial compared to the benefits of performing all preventive maintenance on time. Lexus further strongly recommends you maintain your car with genuine Toyota parts, fluids and filters and to not modify the engine or exhaust system. However, if you read through the IS Forum you'll quickly notice practically all IS owners modify their cars and do not use genuine Toyota parts, fluids and filters. So if you plan to join this camp of modifiers, it makes no sense to agonize over proper breakin procedures because in the long run your future mods will more than erase any engine longevity benefits you might gain from a careful breakin.

bartkat Posted December 1, 2005 Share Posted December 1, 2005 Just go to this site, register your email and VIN and you can access the owners manual, and many other items pertinent to your new Lexus. I have, personally found this quite valuable, and it gives you the info straight from Lexus, and not some bull*BLEEP*ter on a message board. https://auth.owners.lexus.com/lexusowners/a...2fssl%2fWelcome Quote Link to comment Share on other sites More sharing options...

Many questions will be answered right off the bat. steviej Quote Link to comment Share on other sites More sharing options...
