You sir are correct... ![Wink](https://www.clublexus.com/forums/images/smilies/wink.gif)
The 2011-2012 displays the Oil Temp bars very differently....
2011-2012 Lexus IS-F Speedo - Normal Operating Oil Temp.
Below Top indicator shows it moved 4 places..

2008-2010 Lexus IS-F Speedo - Normal Operating Oil Temp.
Below Center indicator shows bars climbed up 3 places.

It took about 10mins for my car to reach that oil temp today (Socal). I know it has a lot of oil, but seems like a long time even for 9-10qts. When do you guys go WOT? 4th bar?

I let it sit for a minute or two while I go brush/wipe the snow off the car. My commute in the morning usually last about 20-25 minutes and it basically stays at one bar. It does go to 2 bars where I'm 5 minutes away from work. I rarely see 3 bars. When is nice weather time again?

Long story short. you are going to wear the engine no matter what...might as well wear it while driving and getting a little closer to the destination.
I am a chemE and designed engines for a short period of time. ( although the engines were not automotive in nature the principle and practice of operation is the same).

Lobux, while I'm seeing quite a few people mention 2 and 3 bars on the oil gauge, what's your opinion on warmup time under normal driving conditions for the Transmission to get up to temp. Coming from a Acura TL which had a new Tranny at 25k, 40k and 900 (thank God under warranty) , I'm always wanting to possibly extend the life. Thanks!
