engine run in
 

Hello all,
I have been on the R1100S (motorcycle) forum for a couple of years, but just broke down and bought my first sports car. 02 911 coupe. Any special advice on running the engine in? Opinions on motorcycle run in are varied to say the least. Thanks

The only Porsche I could afford was well broken in by the time I was behind the wheel...but I was always told to take it easy on a new motor for the first 1000 miles. My .02 cents worth.

From what I have experienced and read, get engine up to temperature, run hard, but not at constant RPM. This is better than taken it easy and breaking it in easy. But make sure the temp is up to operating temp first.

See this page. If you baby a new motor, the rings will not seat. You don't flog it, but don't baby it either...

After that, follow the recommendations of running it normally without redlining it, and vary the RPM's... (which varys the outward gas pressure on the rings, further helping them seat.)

These engines are very different from the older air-cooled ones that we know and love. I would ask the Porsche dealer what they recommend. For a while there, the engines were broken in at the factory (I believe)...

I just kept the revs. below 5000 for the first 1000 miles (some exceptions) and below 4000 for the first 500 miles.

Vary load and avoid the 1500 mile highway trip at constant engine speed. City driving is what you want to do.

Use comon sense. Don't floor the cold engine at low speeds etc. Make sure its warms up properly and remember that the water being at temp does not mean the oil is there yet.

Mine hasn't used a bit of oil in almost 2 years and 6.500 miles on the clock. Answring Wayne the dealers recommend the same thing. Keep it easy for the first 1000 miles. But let's not forget that Porsche runs those engines (yes every single one) at redline for several minutes as part of their test procedure.

On a final thought if you are planning to waste the engine make sure it happens in the first four years so you get a new one free of charge under warranty. ;)

Have fun and drive it.
