Default Sport mode when first driving to warm oil up quicker.. yay or nay?

Lately been addicted to sport mode for even mundane driving. The way the car feels like its claws are always out, and the glorious unfettered barks and roars makes even traffic feel fun. These 991’s truly can feel like luxury sport sedans or pure sports cars with the flick of a button. PASM on Sport, X pipe doing its thing, H&R’s giving that extra element of firmness.. I haven’t enjoyed this car so much since the day I got it (keeps getting better). Typically I’m either driving it calmly in auto/normal, or wildly in manual/Sport+ when it’s open road fun time (i.e usually practice more extremes). This auto/Sport middle ground approach is pretty new to me.

I’ve also used it as a means to warm the engine oil up quicker (and decrease brake wear as a natural bonus, I guess), of course keeping RPM’s under 3K until the temps get to operate norms. Is this ok? I figure it’s a no brainer that it is, as long as RPM’s don’t go too high, but can’t hurt to check.

It does bring the oil up to temperature quicker. And I dislike the 1k RPM PDK shifts, so starting up in Sport mode helps with that too...

won't hurt if u keep revs modest - but not a difference maker really

Yeah PDK shifts super early in normal mode. Sport is just about perfect. Sometimes in traffic or cruising speeds I’ll manually force an upshift when in sport, if it holds RPMs a tad too needlessly high, but most often it’s right on. I also love how it enhances the g forces the car emits in all directions (engine braking, etc.) even when you’re at low speeds. Brings out the “911” and sports car’ness.

What’s a rule of thumb to not go over when the engine is cold? I figure 3K or so.

10-4, not over 3k until 180-185F.

Normal auto is slowest by far as the car tries to minimize the engine RPM. Sport auto improves as the RPMs increase over normal auto but Sport auto still lags the manual shifting modes. Within manual mode, the progression from normal to Sport to Sport+ appears to make a difference but it isn't much.

Mode does not matter. It's all about the rpm's. FWIW, I keep mine under 4,000.

I drive my 991.2 Carrera T almost exclusively in Sport mode. I’ve noticed the oil temperature settles in the low 90s centigrade, but when in Normal mode, the oil temperature seems to be a good 10-12 degrees centigrade hotter... Mine’s a manual.

Yeah, agreed. There is a difference between sport/sport+ in manual mode but it's not huge. Or it's simply something that happens the harder you drive where you're not focusing on it so much. I'm sure on all out track performance it'll make some difference, especially with the dynamic mounts, etc.

Sweet. Easy enough to do. I sometimes "cheat" a little and drive it as I want to at 175F, but hopefully it's fairly negligible. Or I'll just always be sure to wait for those few extra degrees.

I recently started driving in sport+. I find sport shifts too early as well especially before going into turns. I often switch to sport+ at 150 degrees.

Normal mode for me without getting after it until oil is at 150 degrees, then Sport mode and game on.

The first thing I do right after starting the car is put it into sport or sport+ mode, without fail. I can't think of a single reason this would be bad for the car if you warm it up properly.

I also always drive my cars in manual mode so there's no issues with it getting the revs up too high in those modes before the engine is warmed up, which could be an issue if you leave it in auto mode. (Not sure why anyone would want to drive these cars in auto mode at all, but that's a different subject.)

My sense was that not just below 3000k rpm but also to keep the throttle inputs modest during warm up

I've read a lot, on this forum, that Sport mode "opens" a secondary oil cooler that helps manage high engine temps. And I have indeed noticed a significant drop in oil temp when driving fully warmed-up car. So it seems to me that cold driving in Sport would hinder warm-up by way of the additional oil cooler. (unless the computer only access it after a certain oil temp is reached).
