Should an oil cooler help?
Or a 2layer aluminium radiator?
Personally, I'd consider a different oil and improve on your cooling system, ie-better coolant, confirm fan is working fine, confirm radiator cap is working fine, check thermostat, confirm the condenser in the front isn't clogged causing the airflow to be restricted to the radiator, that sorta thing.
Oil cooler isn't necessary unless your car is always on track. Alu rads are overkill too unless your current one is spoilt and you're just looking for an excuse to change it to Alu, then fine. Otherwise unnecessary money.
And I said it seems a
little hot. Still within normal parameters. Despite what quazacolt said, 120 is too hot for your car unless you're running on high compression or turbo setup and all that good stuff. As long as it stays between 80 to 110 thereabouts you're fine la. Besides, your temp sensor could be inaccurate.
