I need to change the oil in the DSG’s headstock firstly because I don’t know when it was last changed and secondly as it doesn’t like the cold. When the weather turns colder the motor hasn’t got enough torque to start in star, it just sits stalled until the starter switches to delta then starts up with a big current surge. This not being good for the lathe and Likely to get me in trouble with the neighbours for making their lights flicker while they are trying to watch Eastenders. Because the lathe has been fine all summer, since last winter I’m blaming whatever oil is in there. Normally I wouldn’t be too fussy with oil and use any modern substitute that is suitable, but in this case I think I may have to be a little more selective. The manual specifies Shell Vitrea 27 from what I’ve found the closest available equivalent is Mobil DTE oil light but it’s very expensive. There’s a company on eBay called Westway lubricants selling an “equivalent” to Vitrea 27 but I’m a little dubious to what’s in the bottle. Or do I just go with a quality hydraulic 32 and hope for the best? Any input would be appreciated.
