I use genuine Benz coolant in all Mercedes even if it comes in with the green crap. I use genuine BMW blue coolant in all my BMW's. I use genuine Red and Blue coolant in all my Audi's and VW's. I use genuine Porsche coolant in all my Porsches...(even though in my opinion, a real Porsche doesn't use coolant. LOL).
Get the point????
p.s. I use genuine Benz coolant in my 450hp Pontiac Fiero GT
