Message: [QUOTE="TARM, post: 437249, member: 578"] Yep I used the 195° but if I had my choice I would use the 203°. I think I have a very good handle on how these systems function and the how and whys of most of it. I do think many have gotten bad info or have misgivings on how these system work or they understand them but maybe do not understand what temps are ideal. I am sure there are many that understand this stuff as well and better than I on here. But I can say that if you are seeing oil temps beyond 15 degrees of coolant temps even under heavy loads if they are consistent the oil cooler should be suspect. This is a general statement and there are exceptions. I can leave it as the 203 is better and the only reason is was changed by Ford was because the EPA required lower NOX emissions and the other choice was to add a many times more costly catalytic converter to the exhaust or worse yet a EGR system. This small cost allowed them a good run of years without having to deal with more costly emissions until the 6.0L was manf. [LIST] [*]Hot engines are more fuel efficient and make more power. [*]Even fuel is better as somewhat warmer temps i.e. 100°-120° before injection into the chamber. [*]Oil does not reach its rated properties until 212° [*]Oil temps fall below 195° engine wear increase at a increased rate in ratio with that of the oil temp drop. [/LIST] If anyone is interested in the details of the hows and whys I can go into it. I personally found it very interesting way back when I first looked into it. [/QUOTE]
