Anyone using Porsche Classic 20w50 motor oil? If so have you noticed any changes to cooling or oil pressure?

I used Castrol GTX 20w50 for years and years, but I was having a lot of issues with foam on my filler cap. It's said that will happen if you don't drive enough to get the oil hot enough to evaporate the water out of it, but I drive about 25 miles to and another 25 from work every weekday and it was still an issue. Thermostat and cooling flaps are working.
I've switched to Valvoline racing high zinc 20w50 and it seems better. Both are available at my flaps. Edit, I checked it out, and it's not synthetic. Also it does mention vaguely some engineering done to minimize condensation, and also "high alkaline reserve" to neutralize acidification caused by "aggressive combustion residues". |
