Oil temp jumps around… bad oil thermostat?

Yep, thought it might not be opening and/or not opening fully. But my cooler core is still quite hot after getting up to temp.

I generally see the fluctuations around 170-200°, so I’m thinking this is just the thermostat “doing its thing”

What is the temp in your area? It is still 90 deg. down here. I don't even run a thermostatic plate on my car. It goes straight to a remote oil filter and then to the oil cooler. With all the hood vents and fresh air ducting to my intakes, I haven't seen mine get past 180 deg. in 95-100 deg weather.

Upper 60s up here in RI. I’m not super concerned about the temps seeing as I don’t have a vented hood or radiator ducting. Winter projects are to make a better (V2) oil cooler duct and add radiator/intercooler ducting.

I may also temporarily bypass the thermostat with some AN fittings to see if that is causing these fluctuations.
