<Snip> Hmmm - there really isn't a bearing to lube or anything. will investigate.

This is a multi-part message in MIME format. Make sure the noise is actually coming from the front. On my hottop = I had the same issue where the gold screw no longer "fixed" the noise. = Upon a closer inspection I noticed the noise was coming from the left = side. After removing the drum I noticed the heating element had bent = towards the drum and once it heated up it would actually touch it, = making the noise - I just bent it back in place and no more squeak.

Here's a list of common oils and smoke points: http://www.goodeatsfanpage.com/CollectedInfo/OilSmokePoints.htmOf course, any oil will eventually go rancid, heat just speeds up the process, so maybe it doesn't make much difference for Hottop use. I really think a high temp, food safe grease would be better for this purpose; although, I've never really felt the need to lubricate my Hottop. I haven't been following this thread too closely but, although some seem to have had problems with the heating element, the only rubbing sounds my Hottop has ever produced are when the spindle gets off-center.

I'm not a chemist, but the never-to-be-questioned internet says that mineral oil is inert. :-) I'm guessing that the chemical reaction in vegetable oils that results in a rancid taste might be oxidation, which probably wouldn't happen with mineral oil. Dave S. John Blumel wrote: <Snip>

I have used it as part of a team frying malasadas for fund raising for a little church in west Kauai. Hydrogenated veg. oils aren't healthy but they are more stable for frying and lubricating.
The end of the drum "axle" is supported by the metal plate that screws onto the end of the hottop. The "pit" in the center is where one gets the noise. I would recommend peanut oil. It's what I use, is of course food friendly, edible even, and has the highest resistance to heat of any common / natural food oil. <Snip>
John, What I meant by "common" is what most folks have easy access to at home or in the local grocery store and "natural" as being normal/unrefined oil. If we remove the "refined" oils from that list, and the uncommon ones like Grapeseed oil, avacodo oil, and soybean oil, I think one is basically left with peanut oil and safflower oil.
