oil doesnt need to be hot hot to work. most car engine oil is designed to be ideally between 60-100degC . thats why they rate them e.g 10/40 5/30
as long as it reaches a temperature within its operating range then it will be fine. its the viscosity that is important not the temp. you need to make sure that the viscosity is correct for the temp range you intend it to run at, thats the key.

i did quite a bit of reading up when i was runing cars with very high boost turbo engines. i had one engine eat big ends on me twice. once i worked out that the car manufacture spec oil was no longer suitable after eaking all the extra power out of it i no longer suffered any big end failures.
anyway this is a build pictures thread and on that point everything is fine and dandy. its good to see that the pictures have provoked a nice debate
its amazing that on many forums this would have ended up as a flame war, where as on here its a nice discussion with every one chucking their thoughts onto the table.
