I get the GM additive in small bottles, maybe 8 oz? Not sure what's in the bottle, but you use one bottle for the entire amount of fluid the rear end. So, fill the rear, then add one bottle of additive. If you have a quart bottle of additive, then I'm not much help. I was told that only elephants come in quarts- well, maybe whales, too.
Thanks Ormand. I used to have six quarts. A friend gave them to me because he switched to F%rd trucks. Only can find one quart. I must have given the rest away at some point.
