So yes, the thinner oil will be *a bit* better at shedding heat but please... PLEASE, don't blame your cooling system problems on your oil. Just fix your cooling system problem like AZP suggested, don't get a water/heat exchanger setup, get separate cooling systems for your coolant and oil. You're already experiencing a lack of cooling capacity no need to introduce an alternate option that allows your overly hot oil to remove cooling capacity of the new system.
Please achieve optimal oil pressure at your operating oil temp with whatever wt oil gets you to that point. Choosing an oil that's too thin simply because it "runs a bit cooler" most likely is robbing peter to pay paul for lack of a better euphemism. If you're dead set on running a 0w-30 come hell or high water, then you really need to bring down those oil temps. |
Thanks Colin, that's what I am currently working on
I am hoping that Cosworth thermostat with 30/70 mix should help be lower my coolant temps by 15-20 degrees which should ultimately change the effectiveness of the OEM oil cooler since it's coolant dependent
FYI, I have been using 5w-30 not 0w-30 since it gives more protection at higher temps
