Could someone shed some light on oil temps for me? what is safe and what isnt? the car runs usually around 100-110 if im driving round town or giving it a bit round the back roads.
Mostly with street/sprited driving it never ever goes over 115.
(Car is a 5.5 BiTurbo running around 730bhp)
However, at Croft on saturday doing a track day, i peaked around 132 which i feel is very high.
I know a good Synthetic oil can take 125 with bursts to 150 but i still feel anything over 110 to be considered too hot.
Water temp never budges from 94 degrees, the most i have ever seen this is 96.
When on a long motorway haul at 80ish the temps sit at a lovely 88/90 (oil) and 90ish on the water.
So please can someone explain to me why it is so poorly cooled? my C6 RS6 never budged over 108 even after 10 solid laps at Croft, both running similar power 700+ and both big twin turbo engines, the only thing i can think of that aided cooling in the RS was a better oil delivery system, it was a dry sump setup with a large oil rad up front for cooling.
My dad in his E63 (6.2) he peaked at 129 on his oil as well.... we only managed 3 or 4 laps tops before brake fade and excessive oil temps brought us in.
Now i know these cars are not designed for this but even everyday driving i feel the oil setup is poor, it takes a decade to warm up to 80 degrees and just doesnt cool well enough.
What temps do you guys see day to day? mapped or standard, im curious to get a comparison going.
