Hi all. Looking at changing the oil in the next 1500 mile. Not sure which way to go Semi synthetic or Fully synthetic. Car is 2002 Octavia 1.9 SDI unsure of what's in at present having not long had the car got service history but it does not say what grade was used. Looking through previous post was thinking of using fully synthetic 5w40. Car has very low miles 31000.

You need a minimum of VW 505.00 spec - 5/30 grade oil and change it every 10k.

Keep a regular eye on the dipstick until you know how much it uses between refills.

 

Personally I put the better spec VW507 5/30 in because the extra 0.1p/mile it costs is irrelevant and these engine can go for well over 250,000 if looked after.

 

vwspares.co.uk is worth a look - I've been using them for years

 

I use cheap stuff from from carparts4 and my car has 234000 on the clock, runs perfectly
