Title: Oil change over 100k miles.
Post by: brewey on 11 May 2013, 15:49

Quick question guys as I can't seem to find a definitive answer, the old girls about to tick over 100k so I'm planning on treating her to a service but should I continue with 5/40 oil or change to 5/30? I'm sure that I've read somewhere that you need to change to 5/30 when the engine hits 100k because of wear etc.

Final question a lot of you seem to use quantum platinum, however whenever I search on line it seems to be listed as PD oil. Do VW use the same oil for both or is there some petrol specific variant I need to find? I have previously been using castrol but have seen Quantum at good prices.

As far as I'm aware it's because as the engine wears the more viscous oil can seep through gaps easier. I don't know if there's any merit in it though that's why I thought I'd check. How much do you pay for 5 litres of Quantum?

I pay about £26 from tps they always sell it cheaper if you buy your oil on the last wed of each month

there is no benefit, 5w40 is thicker than 5w30 so you would be moving down to a thinner oil.
