Hi Scotty, How should I break in a new engine? There are a lot of posts online saying that a sports car needs a hard break in to seat the piston rings correctly and that the owner's manual (keep it under 4000rpm for 1000 miles and vary speed/rpm) is not the best break in. What is your opinion?

I love your channel and I have been a long time subscriber. Thanks for all the wisdom!

most modern engines really don't require a break in period like they did when I was a kid in the 60s. But I'd baby it the first 500 miles anyway
