Search this site for other threads about
oil coolers and thermostats. When I did that it seemed that the only t'stat that could be trusted was the Canton unit, so that's what I used. Also, just like the other two comments above, you need it to keep the
oil HOT enough except under racing conditions.
If I were doing it again, I might just dummy up the
oil cooler plumbing and make it look like I was using it, but just run the oil through the remote filter and back to the engine. My oil runs very cool right now, even with the thermostat. I'll have to wait for summer to see if it works well enough to keep it in place in the heat of South Carolina.
