I'm not running FI yet, but am wondering... when running FI, your engine get's hotter right? That's what our instructors have said. In this scenario what would be a good preventative engine failure procedure: Running thicker engine oil or running oil through oil coolers or both?

I have yet to take the engine performance class where this is talked about in more detail. Also is there such a thing as liquid cooled oil coolers?

Thanks

 

yes the engine will create more heat. anytime you compress a gas (air) it will generate heat, diesels work because of this.

in my turbo civic i run 10w-30 and run an oil cooler. some people run even thicker oil but 10w-30 is just my preference.

as far as avoiding engine failure, cooling the oil is always a good idea to avoid breakdown but more importaintly, use parts that can withstand more heat and pressures such as forged pistons.

stock honda oil coolers are 'liquid cooled' in a way. coolant flows around the cooler which helps warm the oil quicker when its cold and cool it when oil temps exceed the coolant temps. i never used one because i dont see it as very affective. my oil is about 140-180F and my coolant ranges from 170-200F
