I dropped skids on the way out of City Subaru when I picked up MY06 WRX STI and never had one issue with that car.

I bounced it off the rev limiter & asked "is this ok?"

there is a guide to breaking in engines by a guy who did racing bikes, his method to get the best piston ring seal was to warm up the engine by puttering around and then when it was up to temp pretty much thrash the tits off it.
http://www.mototuneusa.com/break_in_secrets.htm there is the link. |

I don't agree a single bit with that guys method, flogging the hell out of cars straight off is not good on things like bearings and the like, the other issue i have with his method is looking at all the different pistons hes got, especially the ones that have been running race fuel and are shiny ally, he has been running his mixtures too lean and pretty much at the point of melting, a properly tuned car should still have some brown/black on the crowns, not a big thickl layer, but a small amount, if its just bright clean ally, you need to get more fuel in there pronto...
the best method ive found, and its worked every time for me is as follows 0-200 km drive it below 5k, minimal or no boost 200-500km keep it below 5k, but drive it a bit harder so it gets boost in there, this will get the rings sealing to the bore properly 500-1000km gradually as you get more km on the motor start winding it out to red line and giving it a harder time, by the 1k mark you ready to have traffic light drags and thats the way to do it, it gives the motor time to seat and settle initially without risking the rings not sealing properly, works a charm..

from that link -"There's a very small window of opportunity to get the rings to seal really well ... the first 20 miles !! "
i have never bought a new car, but id say that most of those 20 miles would get used during shipping the car, and in the car sales yard etc... |

And i've lost count of the number of times i've seen brand new cars getting thrashed around with dealer plates on. I wouldn't stress too much about the run in period. I took it fairly easy for the first 500 on my 07Xt and then let it rip. Now on 70k and runs great with little oil usage. Motors are pretty good these days. You very rarely see a car smoking compared to 10 years ago. Much more likely to end up with a stuffed motor from a failed cooling system, timing belt or fueling rather than rings or bearings. Although subaru have had some well publicized bearing failures over the last few years, at least they seem to honouring all warranty claims. |
