The fan limit should be set at 110/150

Old School was Good School! Those old furnaces were tough as nails and surprisingly oil furnaces have not had the quantum leap in efficiency that gas furnaces have. Cannot make them condensing (without huge problems) so yours is not terribly inefficient IF it is properly maintained and setup properly once a year. You should have 2 new CO detectors in your house. One by your bedroom.

Cheers.
Pay it forward, help someone else with what you are good at.

May be time for a new one.
The belts etc are covered in the service contract. I will let the techs know but I am not sure if they will replace it until it breaks.

No many won't. Good techs will check wear and tear, and replace before it breaks. Saves the company money. And them going out on a call that is avoidable.

You are absolutely right. The belt costs no more than 10 bucks and I wish it was replaced during servicing.

Here's part of what my contract states

will repair or replace, during the life of this agreement, at no extra charge to our customer,
all parts included in this agreement that may become defective due to normal use or wear and tear.

WARM AIR SYSTEMS
blower bearings
blower circuit board
blower complete
blower fan
blower fan belt
blower motor*
blower pulley
blower shaft
blower wheel
fan control
fan limit control
* up to 0.5 hp ECM variable
speed motor included

Pretty much everything is included but the heat exchanger.

Looks good.

Now if only they could tell what a worn belt looks like.
