993 engine break-in
I just recently bought a 96 C2 with 2300 original miles on it. I realise this is not something anyone has had to deal with lately but what is the break-in proceedure for this engine or do I not need to worry about it? I had to order new manuals which could take 4 to 8 weeks I'm told so I don't know if I should be concerned about the RPM levels. Thanks in advance for your help.

At 2300 miles the engine is pretty much broken in already. There isn't much you need to do differently to that engine except to drive it hard.

I'll agree with Robin, except that I'd change that to say that the "initial" break-in has already been completed. The initial break-in is when you drive it easy, the rest of the break-in is when you drive it hard. Your car will probably still use about 1 quart of oil every 800 to 1,000 miles (that's normal). Keep driving it hard, and oil usuage will decline (at ~10,000 to 20,000 miles) to ~1 quart/3,000 miles.

A typical routine driving habbit of mine consist of ---
Morning warm up I shift before 3000 rpm, step lightly on the gas pedal, I drive it easy like that until I see that the oil thermostat is opened (you can tell by the oil temperature gauge needle you will notice that the needle reaches a little above 194 degrees and then dips back down just below that)
Once it is warmed up in first gear with no cars ahead of me I would floor the gas until it reaches just about 1000 rpm before the redline, of course I only floor the gas after the clutch have fully and smoothly engaged.
Same for the 2nd gear, I try to give time for the sycros to work between shifts, and when the clutch fully engages, I floor the gas again until 5000 rpm and then after that I shift directly to 4th gear and just cruise, since most of the roads I drive on daily is base on a 45 mph speed limit.
That basically consists of my daily driving, and I get consistant 18-19 mpg.

Robin and others,
Thanks for the quick response and helpful info. I have been keeping the RPMs under 4K so it's great to know I can now run it up when shifting, but only after the proper warm-up. Thanks again.

Thanks to everyone for the responses. Guess I will shift a little higher in the range. PCA Potomac (DC region) does have track events, I just have been lazy in signing up! take care,

Robin - with regards to the picture of the oil temp gauge (great idea, BTW), I thought that the first mark was approx. 125 degrees and the second mark was approx. 150 degrees.
Am I mistaken?
