badboyV6 4 Posted January 10, 2005 Report Share Posted January 10, 2005 Just popped down the road for some smokes and encountered a lovely wide ,traffic free, A road. Decided to have a bit of fun- Gave it some stick and was going way to fast- ah well In 8 miles my fuel gauge has gone down just over a 1 notch. Its taught me to be a little less lead footed! I recently changed to fully synthetic Castrol RS 0w 40 and put in 750ml of Slick 50. I was a bit worried about this first of all, due to some posts about leaks etc, and the viscosity being to thin. The last day or two the engine has really quietened down (i was contemplating changing tappets before!) and it feels the smoothest (and quickest) it ever has! Highly recommended combintion and i know this remark will divide opinion! Link to post Share on other sites
Eat this 2 Posted January 10, 2005 Report Share Posted January 10, 2005 i use 5-40 full synthetic i may try a bit of slick 50 Link to post Share on other sites
mk3anni 0 Posted January 10, 2005 Report Share Posted January 10, 2005 Heard that slick50 fooks your engine, and that all there claims are unfounded.....I certainly won't be using it. Link to post Share on other sites

Slim 0 Posted January 10, 2005 Report Share Posted January 10, 2005 Slick 50 is great for older cars, but I don't think a modern engine like a VR6 really needs it to be honest. There's not a lot of things that you can buy off the shelf in your local Tesco that will make your Golf run better than VW intended. Link to post Share on other sites
badboyV6 4 Posted January 11, 2005 Author Report Share Posted January 11, 2005 yeah - just read up on Slick 50- seems they went through a law suit in 1996/97 due to unfounded claims- and lost! As a consequence they had to stop making unfounded claims. The PTFE is actually a solid (powder) which is approximately 0.05 microns wide, whereas the average filter only lets through particles smaller than 0.02 microns- so your PTFE supposedly just gets clogged in your filter....i dont likr the sound of that! Ive used it with all my other GTI's and VR6's over the years though and never had a problem :? Wont be buying it again though- we live and learn Dont agree with there being anything wrong with Castrol RS- putting any fully synthetic oil in an old engine is a bit like russian roulette- fully synth acts like a detergent actually cleaning deposits and sludge (and if used from new leaves less deposits than a semi or mineral) - hey presto leaks! If your engines a dog- dont use it;) Possibly the slick 50's maybe thickened the oil im using- whatever it seems to be driving a lot nicer!! And ive got no leaks! Link to post Share on other sites
Eat this 2 Posted January 11, 2005 Report Share Posted January 11, 2005 i use full synth and atm there have been no leaks it always runs sweet as a nut and i think iv got a pretty good engine going off the rr day results but it does use a little bit more oil with it being thinner but nothin drastic Link to post Share on other sites
badboyV6 4 Posted January 11, 2005 Author Report Share Posted January 11, 2005 Yeah i agree- im getting the same impression- when i bought the car i had no idea when the oil had been changed but under full throttle it sounded very tappety- was honestly expecting to buy new tappets- with the oil being so thin i wasnt expecting it to quieten down- once id added the slick 50 after a couple of days it has become sooooo smooth and quiet. As there is no actual scientific proof that Slick 50 does anything at all, its strange how its become so damn quiet! Link to post Share on other sites
Geastb 0 Posted January 11, 2005 Report Share Posted January 11, 2005 I use synta silver - the back of the head gasket is leaking, the tappets rattle when cold and i'm burning oil! looks like i'll be putting engine number 3 in soon! I mite give the slick 50 a go to see if it quietens down my tappets tho. Link to post Share on other sites
badboyV6 4 Posted January 11, 2005 Author Report Share Posted January 11, 2005 OMG m8- thats not good news. If doing what i have done did not make a difference and i read the comments i probably would perform a premature oil change but seeing as its running sweet as - im happy for the moment! Mine was burning oil- suspected valve stem oil seals- it seems to have calmed down now (from what i can see) though so may have been down to very old oil. Will have a proper look fro any smoke on RR day when Vince is caning my car!! Link to post Share on other sites
antera309 3 Posted January 11, 2005 Report Share Posted January 11, 2005 I always used Synta Silver 10W-40 in my 1994 VR6 with good results. Link to post Share on other sites
jaysVR6 2 Posted January 11, 2005 Report Share Posted January 11, 2005 I was told by VW that the VR wasn't designed to run on fully synthetic, its just too thin. 10-40 is what i'm using and it seems ok. I don't know how quiet its supposed to be but it sounds ok. Everyone can tell me how badly it rattles on the RR day! Link to post Share on other sites
pete8tch 0 Posted January 11, 2005 Report Share Posted January 11, 2005 my engine was rebuilt by dubsport just before i got it they told the guy to use castrol magnatec 10 40 which i keep up, the engine is totaly clean inside the filler , and they have a good rep. Link to post Share on other sites
badboyV6 4 Posted January 11, 2005 Author Report Share Posted January 11, 2005 Strange one that Jay- My local VAG parts counter told me that they used to sell synta gold fully synthetic and used to use this for all VR6's in service too. However they dont bother stocking it anymore.... Link to post Share on other sites
