I agree, that is way too hot in such a short time.
On mine, it takes about 10 minutes of driving to reach even 180-190. On the very hottest day (116 degrees), my
oil temp went up to 236 degrees.
And Fixit, I have adopted your advice about standing on it only after she reaches 180.
And lastly, am I doing this right? My guage reads C.
temp *9 /5 + 32 = temp in farenheit
