Re: What Race Oil do you trust?
SSDiv6 gave a good answer. In my experience it is really hard to get/keep that much heat in mine unless I am making laps within 20 minutes. The double races I hit and making late rounds of both I will see 250°. I am on alcohol though. I try my best to never hit the water with less than 150° oil temp though. |

Interesting sidenote, occasionally on the dyno, you accidentally get the oil too hot prior to a pull, counterintuitively the best thing you can do is fire the motor and it instantly sucks the heat out of the oil, it will drop 20 degrees if not more. Bringing up oil temp with the heater while the motor is turned off is easy, very hard to increase oil temp while the motor is running. Monitoring oil temp on a dyno definitely proves that cold oil sucks a lot of HP. |

Right on the money on an engine loosing power with cold oil. How many times have you removed the oil cap or valve covers and seen the accumulation of moisture before you make your first run of the day? I believe the best approach and practice would be to heat up the oil or run the engine until you go above 230 degrees F to get rid of the water vapor and burn the deposits prior to the first run of the day. A heater would be the best way and economical since you would not be running the engine and wasting race fuel. |

as far as pumping up lifters a stocker shouldn't have had a lifter that pumps up for a VERY long time.. |

Re: What Race Oil do you trust?
How about when you have Sherman or Smith "hydraulic" roller lifters? Can thinner oils be counterproductive?
