Engine oil/tiptronic temps

[ADias]

What is the oil temp during extended drives at 4000RPM+ and high ambient temps?

Any idea what the tip-transmission fluid temp is under those same conditions?

No one drives these cars on the road at high-revs?

4000 RPM in 5th gear (Tiptronic) is over 110 MPH. Very few places you can do that sustained.

OK. Sustained 80MPH+ (3000RPM+) drives in the West (Nevada, Arizona, etc.) oil temps. No one?

Hi,

At the track I see about 25F higher temperatures.

normal oil 200F

Track oil 225F

Hi,

Temperatures are 25 F higher at the track.

Normal Oil 200 F Water 175 F

At the track Oil 225 F Water 200 F

I average about 6 miles per gallon at the track. I reach a top speed

around 126 to 128MPH.

During the past eight days...

Air Temperature: 80-90

Car Speed: 60-100

Oil Temperature: 200-225

This will answer your question.

Two days ago I drove my C4S at speeds between 200 Km/h and 255 Km/h (+/-130 and 160 mph) for 160 KM (+/- 100 miles) at a toll highway somewhere in northeast Mexico, the exterior temperature was about 39°C (102°F), the oil temp reading was between 115°C and 125°C (240°F and 260°F) during the hi-speed driving. The coolant temperature stayed at dead center all the time (80°C, 175°F). The A/C was on all the time.

I was a little worried about the condition of the oil at such high temperatures but the oil temp. gauge doesn´t have a red line so I guess everything was OK. The normal operating temperature in city driving at high ambient temperatures (35°C-40°C) is between 95°C and 105°C (200°F and 220°F).

I should add that at that at almost 40°C and 1000' over sea level, the car seem capable of just a few more Km/h over the 255 km/h that I drove it, the acceleration at that point was pretty slow, maybe to 270 km/h tops (167 mph), well under the advertised 295 Km/h (183 mph).

I wonder if the top speed tests are done at ISA temps and at Sea Level, with the A/C turned off. Maybe under that conditions the car can reach the advertised top speed.

The drive was a pleasure anyway. I´m looking forward to the next one!!!

I heard that high test Mexico gas is low test American gas. Did

you fill up in America before you did your sprited drive?

Yes I was coming home from South Padre Island, Tx and I topped the tank there with 93 octane gas. I attribute the power degradation to the high temperatures.
