Simple, just change oil more frequently. daily car usually change around 10000 miles and if you track a lot just do 7000 or 5000 miles interval.I'm confident it's not going to overheat or even pull power because my climate isn't even hot to begin with, plus the car already has cooling mods (PWR radiator and hood louver). The car doesn't have an oil temp sensor and only estimates it based on coolant temp, so oil temp doesn't impact the performance either ways.
The only concern I have is with the engine's longevity if the oil thins out too much.
Switching to higher viscosity might have the opposite effect on oil temperature. In exchange for the added benefits of a thicker oil, friction increases which technically would drive oil temps upward.Well that certainly sucks. After reading through the F3 K20C1 manual from HPD that some on the forums talked about, it looks like they don't want the oil temp to exceed 240 degrees for 0w20. In that case I might have to switch to 5w30 and take a power and temperature penalty.
A quality 0W20 will be more than adequate if you arent worried about racing in hot climates. @Lust has several Blackstone lab reports that attest to that (iirc). Grab yourself some Motul 300V and have at it.I'm confident it's not going to overheat or even pull power because my climate isn't even hot to begin with, plus the car already has cooling mods (PWR radiator and hood louver).
