At which oil temps do you consider flooring at?

TheMidnightNarwhal · 08-05-2018, 09:21 PM

My manual says operating temp is 100c, which is 2 ticks bellow middle of gauage.

Do you consider flooring the car as soon when it reaches 100c or should I wait?

I floor it right after startup, though I live my life a 1/4 mile at a time.

Oof

I don't floor it any cooler than 170degrees. My turbos have 145k miles on them.

We're speaking in Fahrenheit here? If so, that's 76 Celsius. My Canadian manual says operating oil temp is 100c which is 212 Fahrenheit.

I saw another post where they said like 150 Fahrenheit is good, I don't understand why the USA values seem so lower where they say it's ok to push it

?

When the gauge moves off of 160F, I give it the business, never before. 96,000 miles of reliability from my N55 so far.

See once again I'm surprised, 160f in celcius is 71. That would 30c under operating temp.

I guess our manual is different

Altough you do say you are on the N55 maybe it's different.

9krpmrx8 · 08-06-2018, 09:39 AM

I don't really care what the manual says, 0W-40 at 160F is working really well so there is no worry as far as I am concerned. I emailed the Mobil1 tech center regarding this issue years ago and they confirmed that 160F is warm enough.

335e92tx · 08-06-2018, 09:41 AM

Min ~180F for me

maybe just accounting for the crazy A* mercans

Right, if in the end that temp gauge is stricly for oil, you could technically look up the technical info on the oil and see it's operating tmep.

I guess maybe the temp in the manual was for the oil it had originally and now today oil tech is better.

I'll check the oil I buy when I do a change this weekend and I guess I'll go by that to!

Needbmwpartzz · 08-06-2018, 09:58 AM

1 minute after start

Beisofmarko · 08-06-2018, 11:33 AM

When gauge is somewhere between 70 - 80 celcius, 170 fahrenheit?

b92 · 08-06-2018, 11:54 AM

As soon as the gauge starts moving, so @ 160 F. Never before.

Oh nice we got the same car... almost!

But oh yeah uh? I used to always wait until it goes to the middle, then after reading the manual 100c (212f) but ok, I guess I'll give a bit more before.

Haha yeah, I just hit 56k miles yesterday so we're very similar there too.

The 200-210 F range might be the ideal temp, but I have no concern of doing any damage between 160-200 F.

Yes, I didn't read it anywhere in a manual and I have no scientific explanation. I just don't want to beat on a car that isn't sufficiently warmed up a bit, but it doesn't necessarily need to be at normal operating temp either which is a bit extreme at 245 on these cars.

Also, I'm sure the engineers accounted for the fact that your average driver wouldn't think about this kind of stuff and just gets in and starts boosting out of the driveway

IllSic_Design · 08-06-2018, 02:40 PM

I always try to wait for the temp gauge to move before hammering on it. I know that at 160 F the oil is at a good working temp and no abnormal damage should be done at that temp from the oil being too cold/thick.

NA55 · 08-06-2018, 09:01 PM

just above 82*C (180*F) seems to be the most consistent..

whyzee125 · 08-06-2018, 10:18 PM

Once it's about 2 ticks above cold, never before for me. 165k on one original turbo (one was replaced at 22k) and running just as strong as new.

Tiron · 08-07-2018, 10:50 AM

Just like several other guys here, the moment my needle moves off the bottom of the gauge (160F) its go time. At this point the coolant has been to full 212F operating temp for several minutes.

Same here... just above 80c🙂

once oil temp hits 160f its safe to start driving the car hard.
