Hi, my burner motor (that sucks air in and powers the oil pump) has started
whistling. The whistle starts about 2 minutes after the motor first spins
up and comes and goes during operation.
Apart from giving it a good clean, just wondering if I can / should lubrica
te it and what sort of lubricant I should use?
Here’s a link to the type of motor : https://www.ebay.co.uk/p/Burne
Thanks for any advice!

Whistle or a squeal?
Others have said bearings but I'd expect more of a squeal and for it
to not come and go once started.
A whistle could be from air flow through/around something, somewhere.
Give it a good clean out and see if it goes away.
Looks like a pretty standard burner motor with fan one end and oil pump mount at the other.
There are a few standard failures that could produce a whistle.
Fan touching the casing especially when warmed up
Bearing failure, likely the pump end one if the pump shaft seal is failing and allowing kerosene to reach the bearing. Commonly used bearings are shielded type with high temperature rating (C3 type)
Oil starvation - most likely cause part blocked filter.
