Hi Michael
I have an oil cooler in my 2500 PI and use the same grade of oil year
round,Duckhams Q, I do however have an oil stat to speed the warming
process. The average winter temp here is in the single figures (Celsius) and
the car is warming up within about a mile, no different from before I fitted
it!
