I have a 2000 eldorado and the Barrs Head gasket repair mix with any anitfreeze worked on my car! It has held so far for 1 yr and 9 months! I live in FL and it has worked thru 2 HOT summers! Car had only 120000 miles at time repair was needed and it flipped last weekend to 150k and I stomp on it and no problems!! so all you who say you can''t get a miracle in a can maybe not but I say I got one in a plastic bottle! Yes I too like to fix things right but I just cant afford to do that fix for I am a woman and have to do all my repairs myself for shop fees are out of my reach. I thank the makers of these easy fixes! Have had no problems with the car since no codes gets 18 mpg in city, and 22-28 on Hwy and for a old big car I think thats good! straight up NORTH its a STAR!
