    okay im confused about what oil to use for my 1999 A3 1.8t sport. have scanned in the page from my manual but still none the wiser! (see linky)

    can someone recommend the type (VW 500 01?) and more importantly, a make of oil that is suitable, im on annual servicing if that makes any difference?

    you need fully synthetic. after an extended period of using semi our fine turbo lines get clogged

    some fully synth 0/40 would be good, i think 10/40 is a little too thick on cold start, halfords do a reasonable one iirc. i'm on mobile1

    i went to castrol's website and it gave me this info:
    so i would assume this one from opieoils is the same:
    ..as it seems i can get 5 litres of gtx for a little more than 1 litre of mobil1.. good/bad choice?

    I use Castrol Formula R 10W-40 and find it ALOT better than the previous oil i used (Mobile 1 full synthetic).

    go for it, use whatever is cheaper

    btw 5/30 is too thin for prolonged use same as they use in long life service, increased cam wear. optimum is 0 cold 40 warm

    whats the main difference (advantage?) of using 0w-40 (mobil1) instead of 10w-40 (castrol gtx)?

    as far as i understand there are the usually slight differences between manufacturers product but not that great so any of the popular brands will be fine

    0/40 is thinner (0) on cold start up than 10/40 (10) so more chance for it to circulate through the turbo's on cold which is good, 40 it becomes that thick when warm which is a good thickness for wear rates. contact opieoils for more info they're very helpful.

    Skanky - Magnet - I would either use MOTUL or Castrol Formula R
