Am expecting to be running a MCS
within a few weeks and was wondering whether anyone had any suggestions as to the best engine oil grade for tropical (read mean temperature of 27 degrees C / 80 degrees F) weather.
I used to run Valvoline Synpower Synthetic in my Mk. IV Golf VR6 in the States, with a summer weight of 10w30, so I am planning to use the same oil for my incoming MCS
However, I'm now stuck with the problem of living in the jungles of Singapore, so I'm wondering what grade to use. Instinct tells me 20w50 would suit me fine, any other suggestions?
