I've been around several car forums in the past and this topic seems to always create a bit of controversy. I was introduced to this method of breaking in an engine in a Audi S4 forum. Based on that sample of very passionate car enthusiasts this method seems to work. The secret is creating some negative compression pressure in the cylinders during the break in process...very early on in the life of the engine. I found coasting down hill while holding the gears in the higher RPM range works great for me after a gentle run to near redline. Anyway...here is the link.

Thanks for the advice but even the effectiveness of the negative compression by coasting down hill is subjective.

I've tried the 'owners manual' version of breaking in engines and have ended up with engines that burn oil several times. I drive 40,000 miles a year on one of my vehicles and another 25,000 a year on my second vehicle...so I go through a lot of cars. Not one car where I've done this motoman approach has burned oil. I keep my vehicles to the 125-140,000 mile range. I'm sticking with this motoman approach until it doesn't work.

For sure if it works for you. It's a good idea. Everyone sort of has their own way. I just drive like a normally do. I don't baby it or drive it aggressively.
