Oil Change on W126 1991 500SE

[roygarth]

How often should I (local garage!) change oil & filter?

Which oil should I use?

Thanks

Hello Piers,, the interval between the changes depends on the oil used,if using a semi synthetic like GTX then do it every 7k miles or so,,if using a more expensive oil that meets the min of 229.1 or better then 11-12k is fine
