Hi VW heads... Heres the thing.... = Checked my coolant for strength the other day good down to -40C, but the gauge = tells me its methanol based antifreeze, not etylene glycol. Is the VW G11 coolant = methanol based, or has somebody put an unusual(Old fashioned) mixture in? Plus = how is methanol as regards the dreaded VW engine corrosion = problem?    Dave Perry 87 Syncro Caravelle Norway
