Thanks, i agree on the choices. I've never had anyone ask what I had for coolant. 30 yrs of going to the strip.... Always look for the overflow, though. I think they just know a street car will have a 50/50 blend.
Yes, street cars must have a overflow. a hose and a plastic pop bottle atached with a tie strap does the trick. (depending on how anal the tech guy is) LOL
