I'm curious as to how most of you break-in a new car? After owning a few new cars over the last few years, I think I now prefer a more aggressive break-in. I don't think it matters too much on most modern engines, however I do think high load/WOT is a good thing to fully seat the rings. Thoughts?

This is not specific to an '08 V-6 but I would do the same thing if I had one.

I run 500-600 miles going very easy on the engine trying not to get in situations where I'm at a constant speed. I vary (highway for instance) the speed +/- 10 mph every 10minutes or so.

From that point up to 2000 miles I begin to push it a bit winding it up to 5K or so on occasion. At 2K + I red line it occasionaly and try not to run a droning steady speed during all of this.

Atr 3500 miles I consider it broken in and just drive it. That is also when I changed mine to M1 0W20 (SL). During the break in it consumed 3/4 quart of oil, I topped off with dino 5W20. It has not used any measurable amount since @ 7500 mile OCI's still with M1 0W20 (SL).

Right? Wrong? :dunno: I've used this same procedure on several cars and none have turned into oil users so I guess it's as good as any.

I'm quite a newb at breaking an engine, seeing that the 08 Accord is my first brand new car. I've gotton close to 700 miles on it alright, and I've been staying under 3000 RPM for the most part. On the streets, I drive normally, which is actually pretty conservative. I get variation in speed just by driving normally in stop & go traffic. On the highway, I don't know how silly this is, but I tend to go to a certain speed, then release the gas pedal to slow it down by about 10 mph, drive it there for a minute or two, then speed up again. It drives my passengers crazy. Hah.

buster,

maybe not WOT but certainly 1/2 & 3/4 throttle does well.
