I was driving pretty hard yesterday.
Hard acceleration and lots of wide open throttle, revving up to 6,000 to 6,500 rpm Oil temp was peaking at 110 degrees C. What are people's opinions on when oil temp is "too high"? I am using Mobil1 5W30. At what point should I look at an oil cooler?

I think the answer may lie within the oil itself. Obviously oil's viscosity changes with temperature (it gets thinner or lighter for those of you playing at home) and that is indicated by the number on your oil bottle. One number is its "weight" when cold, the other when hot.
The change in viscosity will also change your oil pressure. Thatd be my main concern. Everything is relative to everything. Even things like compression or even oil pressure itself will effect temperatures. Firstly I'd look into the oil you're using, there'd be some way to find its operating temperatures, websites, sales reps. Hell, read the bottle, you might even find it there. Talk to the guys at herrod that rebuilt your motor. They'd understand it a lot better than me and know whats needed for that motor. Good to see your round the traps mate, its been a while.

Using the factory recommended Castrol Edge Sport 0w40 in my XR5 I've never seen it move from the normal warm temp...sitting just below half on the dial...even on a full track day...didn't move....and that was running a tune, IC, CAI and High Flow Cat...

Steve, I would consider using the 0W40 in yours because of the performance mods you have, rather than the stock 5W30 that ford recommend for the Zetec/Duratec 2.0 engines. I have Mobil1 0W40 in my XR5 and it's running beautifully. And like entheos said, it never moves away from normal temperature even after a kick in the butt

I used to use Castrol Edge 5w30 however I changed to Elf recently, and there was a noticeable improvement in engine noise and smoothness in power delivery particularly in the low end.
Never really considered my engine noisy before, but the difference w/ Elf is surprising. I did a bit of poking around but nothing too much, apparently Castrol Edge meets just enough criteria to be consdered a fully synthetic, though uses cracked hydrocarbons? Anyway, I'm not up with all the jargon. Elf is meant to be a real fully synthetic, along with a brands like Mobile 1 fully synthetic. So while I'm sure the rating of the oil is most important, I think the grade of oil will have some effect as well. In practice the Elf has been a good improvement:

Spoke to the Mobil Lubeline today.
Their advice was that even with my engine mods, to stick with the 5W30. The 0W40 obviously has a wider viscosity range, but viscosity is only one factor in the specification. I know for example that the early Zetec engine was originally specified with a slightly higher viscosity, but the engines had a sticking valve problem and thus a change in specification was made to the 5W30 Mobil advised that 110 C was nothing to worry about with the synthetic oil. And I'll hold off on an oil cooler, because they can apparently cause problems getting up to operating temperature in the first place

What do you consider to be high oil temperature?
