Since people tend to make fun of my Wal-Mart house brand dino, I'm a bit perplexed to find such admiration for a group I oil thats specs are quite a bit worse than the SuperTech. Flash point something like twenty degrees F lower if memory serves me right. I assume group I trades stability for cleaning ability, right?
I also agree that if you want this stuff, throwing a half quart of M1 with four quarts of DriveClean should be less expensive.
