nath 134 Report post Posted August 14, 2012 I have a 20V turbo 5 cylinder Audi with 200+km's. They all say to only use fully synthetic oil on these for the turbo/lines, at these kms does that still ring true due to it being a turbo? It does not smoke at all. I've had one before, but it was lower km's and there was no question. Cheers Quote Share this post Link to post Share on other sites
yng_750 247 Report post Posted August 14, 2012 depends how you drive it synthetics handle the heat of a turbo core better but a thin oil will still burn in the engine if the rings are loosening off etc i would go for something around a 15w but go for as high of a second figure as possible penrite do a 15w50 or 15w60 at supercheap the higher second number speaks to its stability so it will handle the heat better if its around town or open road with the occasional blast go a 15w50 or so preferably penrite semi synthetic if its getting a good thrashing all the time go full synthetic 10w50 and just put up with it if it uses oil Cliffs semi synthetics now are better than full synthetics were 10 years ago Quote Share this post Link to post Share on other sites
nath 134 Report post Posted August 15, 2012 Cheers for that, yeah I'm unsure what is in it now (probably no frills diesel oil) so at the next change I'll go semi or full synthetic as recommended. Not too fussed about oil consumption Quote Share this post Link to post Share on other sites
