I recently changed to M1 after a 8000 mile run with GC and LC. My driving consists of 70%highway and 30% city. I went to take back the old GC today and while dumping it in milk jugs, at the bottom of my drain pan, there was several chunks of sludge in the oil. I'll be honest when I say I've never seen this before and had me concerned and I still am concerned as I type this.
What do you think cause this sludging?? The oil sat in my garage for about a week or so before I got around to taking it back. You think the oil just settled so much that it sludged on it's own or could it really be from my engine?? Thanks,,,,,,AR
