Audio Systems: Goldring GR1.2 turntable, main bearing, imperialoil

Question
QUESTION: Having used my turntable nearly every day for a year, it is recommended that I should change the oil in the main bearing and the oil round the tonearm bearings.
How would you go about changing the oil?
Do you know of any websites that give a tutorial on how to do this as well as changing the oil around the tonearm bearings?

The GR1.2 comes with no maintenance instructions.
Thanks :)

ANSWER: Have you contacted them?

Above is their contact page.  

I suspect the oil change idea is just marketing hype.  Why would the oil need changing?  I can believe you should add oil in case it is drying out; you don't want friction to build up.

There are no high temperatures, no serious environmental afflictions or other deteriorating conditions that would cause the oil to cease working at its full lubricating potential that I can determine.

The oil in your bearing surfaces are essentially at "shelf" condition. Shelf life for the kind of lubricating oils used in a turntable is 10 years.

Finally, to change the oil you would have to clean the bearing surfaces referenced, removing all evidence of the oil and replenish with new, fresh oil. If you find no spigots or drain ports, etc., then maybe it is a service performed by a qualified dealer.

I am curious what the manufacturer has to offer!

PS: I cannot find owner manuals on the manufacturers web site. In today's audio world, that is a bad sign.  Every manufacturer I know of supports their owners with documentation retrieval.

QUESTION: I contacted Goldring and they say that the tonearm is lubricated for life and the main bearing should only be oiled when friction appears.
I was thinking of buying some turntable oil such as:

however this seems a little expensive. Another expert recommended teflon-based oil but I have been unable to find any.
Is the special turntable oil just marketing hype ie) is there a cheaper oil to buy that will do just as good a job?
Thanks again for your help :)


Answer
I will tell you what I would use - and have used on many turntables - machine oil. It comes in a little can with a removable lid.  It is used for sewing machines and the like and it is very good for TT.

It can be found in most hardware stores. Comes in a little can with 2 or 4 oz of oil.  Cost is under 1lb.

Cheers,
