hi Scotty,
i got a 2015 VW Golf Gti mk7 DSG it has 7,500 miles only. may i know what cooling system cleaner that is safe to use? it got contaminated with rust,scales and thin greasy film but didn’t smell like motor oil. i checked the oil cap and dip stick no signs of coolant contamination. no overheating issues at all.

This is the best one I've found. All the Blue Devil products are great.
