No HTwo O

Always below 4,000 RPM's until proper operating temps are reached.

In the Turbo it is easy to tell, because the oil temp gauge goes up, the thermostat opens, and the gauge drops a little. Then, it's party time..

In the Boxster, I only have the coolant temp. gauge. And always wait till it reads 175-180. Is this good enough? Should I wait? How much longer after the 175 is hit? How does this correlate to the oil temp?? Thanks.

Hard to say. My observation though is that at highway speeds (70MPH) on flat roads, oil takes 10/15 min longer to reach op temp after coolant reaches 175F.

waiting until the oil reaches 200 degrees is overkill.

I'd say anything above 160-175 degrees of oil temp is ok to start getting on it.

What technical information lead you to this conclusion?

This is why I shy away from used high performance, low tolerances sports cars. Everyone checks the DME for overrevs, but nothing I'm aware of in the DME will note how many times the chucklehead owner stressed the engine before the oil was ready to handle it.

Quadcammer

at 160 to 180 degrees, the oil is plenty thin to properly lubricate the bearings, valvetrain, and rings.

mercedes benz tends to agree as their oil temp warnings in their AMG vehicles turn off at 80c or 177f

I didn't vote as there is no option for "I drive my car and look at the road, not the oil temp guage"

I'm not even sure how to respond to this.

I take this to mean that you regularly run out of gas, get flat tires, and other issues since you're too busy watching the road to read the gas gauge, TPMS, etc.

Quadcammer

dude, honestly, like I give a ****.

Drive it for 4 hours before getting on it if that makes you happy.

Unless you have conclusive evidence of engine damage that occurred due to a driver getting lively with the throttle at 160 to 180 degrees of oil temperature, your OPINION is worth just as much as mine.

Kuhan

Yes, I don't look at any of the gauges in my car, I just wait until it stops or makes a funny noise. Until that happens, I have a really good time.

Nugget

You have to have something to do while you're on the front straight. Might as well check your gauges.

I would bet that we are a bit overly worried about this. We use 0-40 oil, and it's very thin.
With thicker oils, obviously warmer temps are espec. important for proper lubrication, but with the 0- weight oil, it's probably less of an issue.

Ignorance is indeed bliss. Its also a motherf*cker when it brings Murphy along to play. Enjoy, and may whomever gets your leftover p-cars have a good warranty!

We're also not talking about a 2.5L Camry 4-cyl that struggles to put out 68 hp/L @ 6k rpm, but a (in the case of the S) 3.8L flat 6 that churns out a (still fairly mind boggling) 101 NA hp/L with a 7200 rpm redline. If you buy a timex and want to throw it in the pool, toilet, toolbox, and run it over with the car, knock yourself out. If you buy a highly precise mechanical watch and treat it like ?^%} there's only one person to blame if something goes wrong.

I mean, waiting for 200 degrees of oil temp takes, what, 3-5 minutes? People can't keep their #%^* in their pants that long before driving like a nut? Don't get me wrong - everyone has paid their their own money to drive like a fool if they want, but that doesn't make them any less of a fool.

This post is indeed metal. \m/

I've never understood why someone wouldn't want to take care of their stuff, but hey. -shrugs-
