With my current setup i was running a conventional oil that when colder the car was about .05-.07 slower then i switched to amsoil 10w30 signature series oil and i made a pass cold off the trailer came around didn't cool the car with 185* water temp made another pass and it only varied .01 went 12.12 to 12.13 same lane as well so know the car has synthetic amsoil through the whole drive train and is very repeatable no matter the temperature. just something to think about as well
