His oil temp gauge has a center reading of 250. Even if you drive like a granny in 60 degree weather, the needle will sit on 250 degrees. The gauge tops out at 340. I didnt push it extremely hard....but did maybe 2-3 wot runs in 2-3 gear...and that shot the temps upto mmmm i'd say about 270. Whether it will climb higher upon more induced stress on the engine I have no idea. Is there a difference in the dynamics of 370 and 335 that makes it okay for the 335 to sit in 250 degree oil temp? Im assuming his 335 has an oil cooler installed for that's what i've been hearing from people on this board....but i was quite shocked to see that on his car. I cant see how it's good for the car to have its oil changed every 15k miles with those temps....Please advise. Thanks.
