Engine Oil

Time for a winter service. What Engine oil are people using for their GTA Turbos ? I know the velocity is supposed to be 15w40 but are people still using fully synth or semi synth? Preferred brands? I have been using Fuchs Titan Race Pro R but that seems expensive on Opie Oils at present?

Thanks
Brad

Oil is key to an engine.
I use the Fuchs Pro-S too.
I wait till there is an offer and buy 20 litres at a time.
Compare it to the price of a good oil from Hell-Frauds and you should feel better about it. Oilman keeps telling us all that the key is to have a good Ester base.
All oils are pretty much the same, do the same job, especially in a normal use of a car.
