Check owner manual. Oil temp is not specifically addressed but warmup is.

 

Do you have a oil temp gauge fitted, as I know my Impreza doesn't, I let it run for a minute then go steady for a few miles, then as I reach my destination, steady for a last couple of miles and let it run a minute or so when I arrive

no oil temp guage on the impreza . just a hot indicator light and a cold indicator light . when i got it , dealership told me you dont need to warm the car up at all . what they did say is never drive it if the hot light is on .

 

Lukewarm to the touch.

 

I prime the fuel pump, start the engine, wait about 10 seconds, then start driving.. low load, low rpm, no boost until the pressure stabilizes. If I had to guess I'd say somewhere around 180ºF.

 

Don't drive crazy until it's 160F+

 

Personally, i don't let the car sit more than a few seconds before backing it out of my garage and driving to work, but i always try to keep it under 3500 RPM with no WOT or sudden acceleration until about 10 mins, which is about twice as long as it takes for the dash temp meter to stabilize, which, as I understand, is the general rule of thumb for how long it takes for all components to reach operating temps

or something like that

 

about twice as long as it takes for the dash temp meter to stabilize

That's the point at which my oil pressure tends to stabilize..

 

i let the rpm back down below 1k then start driving gently for about 10 mins more.

 

Don't idle for long periods of time. Get in your car, start it, get your belt on, air con or heat set, radio going and drive away. So a grand total of 30 seconds.

Don't flog the car until oil temp and pressure has stabilized, it usually takes twice as long or longer than the coolant temp.

10mins seems way to long, seems like there would be some carbon build up or other things that would come from that
i do about 1or2 mins at most and thats because im reading the manual (just got on Saturday)
then dont open it up for a few miles, as of course if cold you will have higher oil pressure with load then when warmed up
think more of a focus should be looking it cool down after driving, or staying out of boost the last couple miles before parking

 

Your turbo is oil and coolant fed, it shouldn't take hardly any time to return to a safe temp to shut off. Sitting around for 5 minutes waiting for it to cool down is not helping. Unless you just got off a hot lap or quarter mile or something.

what im doing from now on is just waiting for the oil temp to show up on the display . then drive at under 3000 rpm till oil temp hits 160 degrees . i have noticed carbon buildup on my exhaust tips . i may have been warming it too long .

 

I wait until the TGVs open full then I go.....taking it easy for a while. I have to blip the throttle with clutch partially out to get the idle down though. Otherwise I'd have to wait for several minutes just for the idle to come down. I see carbon on my exhaust tips.
