Jamie 1 Posted February 23, 2014 Just a quick one - seeing as SMX has been replaced, which is the correct oil for a VR6 gearbox? Syntrans 75 or Syntrans 75/90? Quote Share this post Link to post Share on other sites
seanl82 23 Posted February 23, 2014 Redline MT90 is usually the recommended gear oil mate. Available from Opie and you'll get forum discount too. :thumbleft: Quote Share this post Link to post Share on other sites
delfinis38 1 Posted February 23, 2014 (edited) Just a quick one - seeing as SMX has been replaced, which is the correct oil for a VR6 gearbox? Syntrans 75 or Syntrans 75/90? Castrol syntrans transaxle 75/90 Castrol website is your friend just punch you reg no in. I chose this over the redline stuff last year. Bough from opie off ebay It's the correct vw spec.

Jamie 1 Posted February 23, 2014 Cheers chaps. I done a bit of research and found MT90 and Syntrans both recommended so decided to go for the Castrol as it's cheaper. You can get it from Halfords as well so it's convenient and even with the forum discount it's still cheaper than Opie when you add the postage on. Just didn't know whether I needed the straight 75 or the 75/90. Quote Share this post Link to post Share on other sites
delfinis38 1 Posted February 23, 2014 (edited) Do they sell it in halfords. I bought some then took it back because it wasn't the transaxle stuff which is different spec. It's not the multivehicle stuff that halfords sell but I guess it would do. You need 2 bottles. Opie sell it for 21 quid delivered on ebay the correct stuff is syntrans transaxle not multivehicle Edited February 23, 2014 by delfinis38 Quote Share this post Link to post Share on other sites
Jamie 1 Posted February 23, 2014 Is that correct Delfinis? Everything I've read on here and other sites says to use MT90 or Castrol SMX-S which is now Syntrans Multivehicle... Quote Share this post Link to post Share on other sites
delfinis38 1 Posted February 24, 2014 (edited) http://magnatec.castrol.com/en/oil-selector.html Castrol oil selector punch your reg in. Castrol syntrans transaxle.
