Re: Eliminating Remote Oil Filter
I would disagree just a little. To begin with oil coolers may actually help the oil warm up by exposing it to the coolant which warms up much quicker than the oil. On the flip side, under high load (ie turbo'd), a lot more engine heat is absorbed by the oil and needs to be dissipated. Who was it that did oil cooled pistons? That heat needs to go somewhere.
Funny in a way. We need hot oil for low friction loss and cool coolant for higher volumetric efficiency.
Having said all that, in the end it may not make any difference because our engines are small (fast warm-up) and are not exposed to full throttle for very long periods.
