The damn oil temp gauge

[jraymond]

The temp gauge on my 135 takes about 8-10 miles to move off of 160 (dead cold), whereas my old X3 took about 2 miles to be fully warm. This also sucks ass since their is no heat for about 15 miles of driving!?

Is this happenning to others? I noticed this same thing happened on a 335 i test drove.

Will it be ok for me to shut the engine off dead cold everyday? I work 5 miles from my house.

I am pretty sure the temp gauge in your X3 is water temp. The water temp will go to normal level pretty quick. However, the 135i shows oil temp which would take a bit longer.

hmm if i were you i would find the senic route to work

That sucks, I work 2.5 miles from home. I work 12 hour days so time is precious. I would have to get up at 4:15 am in order to do that. CRAP.

Stop worrying about it!

Oil temp is different from water temp. It's pointless to compare the two. Start the car, give it a 30 second warm up, and drive to work. It's that simple.

[peppebmw]

Yeah I noticed this tonight also. I was getting a little worried.

Oil temp takes quite a few more minutes to come up to temp than water. Remember, you don't want to start thrashing your engine until your oil is warm too.

two words: heated seats

Agreed with above observations. It takes ages for the car to warm up. Only driving approximately 20 miles does the car warm up to approx. normal temp. Also, is the "normal" temperature roughly 2 points below the 250 mark?

[white911]

As others have said, the gauge is oil temp. The oil does take a long time to warm up to temp. The thermostat in the Porsche doesn't open for probably 20 minutes. You will achieve water temperature well before your oil will be up to operating temperature.

Yeah, I understand the oil takes longer to warm up than a water gauge - but I still shouldn't have to wait 15 minutes vs. 2 minutes in my old car for warm heat coming out of the vents. :iono:

I personally believe it is very important to respect the warm up of the oil. And yes 5-10 minutes is the norm for proper warm up at least it was on my S4 but that was 8 year older technology.

My 2000 S4 lasted 100,000 miles with 17+ pounds of boost and no turbo failure. I did drive this car in a spirited way but always waited for the oil to come up to temp.

I read about many many S4's blowing their turbos. I always attributed this to not warming the car up correctly.

BTW I am so looking forward to twin turbo again. My 2005 G35 was just NOT fast. I am really really really going to try to leave the 135 stock. The 135 is as fast stock as my S4 was modified!
0-60 4.8, 1/4 13.2 155 mph should be enough for me! For a while any way.

I believe the reason that my S4 became unreliable was that after 4.5 years and 160,000 I had used up its lifespan by "turning up the wick"

It takes 15 minutes for the heater to work? That sucks, 15 minutes of the gf b****in' about how cold it is...lol

I don't believe it takes that long for the water to heat up. I have warm air from the heater long before the oil temp gauge has moved off the peg. Perhaps your thermostat is defective, three to five minutes seems more accurate for water temperature change. In the morning I start the car and drive away. Although I have not timed it; I have warm defroster air within one mile from the house, by the time I get to the second traffic light.

[Stew]

Nice, I am less concerned with the heater working in the mornings living in LA, but its good to know it isn't as bad as I thought.

[mistermojorizin]

how long do you have to wait (for the car to warm) b4 you can start having fun (flooring it)?

[jraymond]

White 911 - your right - I overreacted on this.

I am assuming we can start having fun (flooring it) shortly after the oil temp starts to nose off of 160?

I suspect this is correct. I would like to see the needle come off the peg before flooring it; but, somebody more familiar with branched chain molecules and lubrication should answer the question. It is the approximate temperature that the 911 sees on the temp gauge before invoking a religous experience.

I'd leave it behind and ride my bike. Or have a coworker swing by and pick me up in exchange for a few free lunches each week.

Confirmed today -- 47 F ambient, less then 2 minutes, warm air out the vents.
