Now Im going back to mineral oil. Going to buy 20-50w tomorrow. Read that this oil is good to -10 degree and my car never runs in that cold wheater.
I have also got back to standard cam and lifters from Ford. Hope this will do it now. Im pretty pissed of taking my phone on the high way to get someone to get me.

Penzoil... Wouldnt bother with it again for sure, Mobil 5w-50 is pretty good stuff but is made from a mineral base, so its not what the oil is made from thats causing the problem.
Seriously, dont bother with 20w-50, you will not be doing it any favours.
