Dougal--

I use Delo 15/40 in my C223 and it idles hot at about 25 psi without any flickering of the oil lamp. Normal operating speeds run around 55 psi. My truck has only the stock oil to coolant heat exchanger under the oil filter.

Do you have a pressure guage? Perhaps your lamp sender is marginal. But, oil coolers are good things in most any circumstance, anyway.

Regards--

Paul
