 And it was on a rear-drive Volvo that my friend swears that it took, like, engine oil. You know, it took really fairly light oil in this rear differential. So he made a big point of telling the service rider over and over and over, don't just grab your drum and 90 weight. You know, just please be sure to use the right stuff on this. And they assured him they would. But they didn't. They put the 90 weight in.
