Thanks for the info. How long does it take for the coolant and oil temperatures to get up temperature from a cold start in normal driving?

was the track driving 30 mintues consecutively or with breaks in between? was 118c the highest oil temp you saw? It seems believable and also suggests that this car has very efficient fluid cooling systems.
Funny how Greddy Japan came out saying they saw 140C oil temps at the track as justification for one of their oil cooler kits. Typical marketing lies! |

Stick with the 0w-30. You need the big number to higher not the little number. There's no point in sacrificing engine-start-wear to improve racing protection.

warms up very quickly. I say 10 to 15 minutes for a fully warm engine |

118 was the highest oil temperature reached during the session that I pushed the car the most, basically keeping rpm between 5 and 7 for 30 minutes non stop. |

for winter driving (it gets quite cold over here) i will be using 0w20 during the summer months I am more concerned about oil viscosity at high temperatures since you are usually running at very high rpm. |

This sounds strange but we're talking about "flow". The cSt of 0w (when cold) is closer to the 30 when it's hot. The 5w when it's cold if thicker than the 0w. Let's use a 0w-20 and a 5w-20 for example and we'll use "startup temp" as 75F and "operating temp" as 212F. Flow is measured in cSt, the higher the number the thicker the oil and the less "flow". A 0w-20 starts at 40 cSt then becomes 8 cSt at 212F. A 5w-20 starts at 50 cSt then becomes 8 cSt at 212F. So we know that the 40 cSt is still too thick to provide adequate flow and protection until it heats up and thins out a bit, but the distance between 40 cSt and 8 cSt is less than 50 is to 8. Thus the 0w decreases start-up wear more than 5w because the 0w will thin to an appropriate cSt before the 5w will. There is absolutely no point in increasing the little number in a street car application (and most race car applications depending type of racing) unless you're stranded doing an oil change "Billy Bob's truck stop" doesn't have a 0w-XX oil. |

What hardware/software are you using? I can't seem to oil temp readings.

Ah that would explain it. I'm using Torque with OBDLink MX which pulls back a lot but oil temp is one that I'm missing and would very much like. I wish they would make PID info more available so we could manually add them in. |
