Mushrooms creep me out a bit, @xena914. They just pop up out of nowhere.

Try a slower ramp up with the heat. I found if I start on low from a foot away for a minute, it gives the edges a chance to flow a bit before I go full blast.

Honestly, parkera61 has a good point about the thickness rating. Did you check if the eco-oil you read about had the right heat grade for bearings?

Wait, your friends are actually doing meal math now too, @seanm93? My generation barely knows how to boil water.

It can be a nice gesture if you trust their taste. Some people just like making sure their guest gets a good meal. Not everything has to be a power move.
