Guess I need to up the viscosity of my oil on my other car if it barely/rarely goes past 200 degrees, oil temp.Oil works best over a narrow temperature range of 220º to 260º F. Above 285º F motor oil oxidizes and begins to turn to varnish. Below 220º F, oil is too cool to boil off trapped/suspended water and excess fuel. General rule of thumb is that oil temps should be about 50 to 60º F hotter than coolant temperatures.
Be careful, just because the Honda Challenge cars can supposedly run their oil to 300 degrees, doesn't mean it's safe for anyone else to. Keep in mind that their cars probably have fully built race motors and run a straight grade oil, so it can take the abuse. They probably do engine teardowns much more often than a daily driven street car would in its lifetime.
Also, bearings like lower temps. The lower the temps, the longer the engine would last.
Baffled oil pan = :thumbsup:
Bearings and rotating assemblies in the engine are very fragile as they are. Although not the solution to all problems, baffled pans can help reduce the chances of oil starvation by a shitload.
I've read oil should be 20-40 over ECT, but this info was hard to find in the first place. Should it really really 50-60 degrees? I don't think my K20A2 sees 240 often at all, it's moreso around 220 +/- 10 degrees on a normal drive.
Makes me wonder why other people's cars run hotter than mine.
