Hi,

I'm sure this must have been asked previously but couldn't find the relevant info despite searching the forums.

I change the oil & filter on my 1.2 2002 polo 9n (AWY) every year and usually use Castrol Magnatec 5w30. Coming to buy oil this time round it doesn't appear on the recommended list on halfords/ECP. They recommend Castrol Edge. Also want to make sure I get it right because of the known cam chain + tensioner issues!

1. Is there really a difference between the Magnatec/EDGE oil of the same rating? I want to use the best possible oil and certainly don't want to damage the engine.

2. And is there much variation between oil filters, or is a filter a filter? I have previously used Bosch.

3. Lastly, is it overkill to change the air filter every year despite relatively low mileage (5000 ish), motorway & rural driving?


Any advice is greatly appreciated, thanks!
