VR6Nat 9 Posted January 8, 2011 Report Share Posted January 8, 2011 I use syntha silver 10w40 oil from Vw Ngk spark plugs. Wouldn't use anything else personally. Link to post Share on other sites
Antihero1981 8 Posted January 8, 2011 Report Share Posted January 8, 2011 Yeah i agree with Nat , Synta silver and NGK all the way15w40 is a bit to thick for the winter months Link to post Share on other sites
Antihero1981 8 Posted January 8, 2011 Report Share Posted January 8, 2011 Mood i would maybe think your oil a bit to thin....what make oil you using?on what engine + year? Link to post Share on other sites
VR6Pete 1,455 Posted January 8, 2011 Report Share Posted January 8, 2011 Vr6's should be running 10-40 semi synthetic. Only ever run NGK's in my cars. A few charged people on here have had problems with Bosch Link to post Share on other sites
bungy 2 Posted January 8, 2011 Report Share Posted January 8, 2011 Sounds like the oil you are using is too thin. Synta Silver and NGK all the way. Link to post Share on other sites
eastwood john 1 Posted January 8, 2011 Report Share Posted January 8, 2011 10w40 and NGKs mate, i`ve tried bosch and the vr did not like, chewed them up an spat them out lol, Link to post Share on other sites
Lukey. 381 Posted January 8, 2011 Report Share Posted January 8, 2011 another for synta silver 10w40 and NGK plugs. You may want to adjust the viscosity due to your location, depending if you experience very hot tempsAnd the cheap sinlge electrode BKR*E not the expensive platinum dual ones, (put the relevant heat range you prefer in place of the *, i used 5 which is standard but some on here like the cooler 6 or 7 heat) changed every 20k instead of every 40k Link to post Share on other sites

Sidhu88 1 Posted January 9, 2011 Report Share Posted January 9, 2011 before changing my oil i read in multiple places to run 5w30, i've got 5w30 edge fully synth. aint had no probs since but shud i be running 10w40? Link to post Share on other sites
Lukey. 381 Posted January 9, 2011 Report Share Posted January 9, 2011 This is due to VWs (in my view) stupid oil rating system, where an oil that exceeds a previous standard is, by VWs books, perfectly fine for your car too. So a 5w30 that is 507.00 is fine for the VR6 because that needs 505.01 (the 10w40 spec) and 507.00 exceeds the 505.01 standard, yet we all know 5w30 is crap for this engine.

james4287 1 Posted January 12, 2011 Report Share Posted January 12, 2011 yet we all know 5w30 is crap for this engine.Really? Why is this?Reason being as when i got my 60k miles vr6 i changed the oil and used 10w/40 castrol magnetec. When i bought the car i had a issue with it loosing compression when cold. After alot of thinking i decided to try a thinner oil as i suspected the thicker 10w/40 was holding the lifters open when cold. So i changed to 5w/40 oil and have had no problems ever since. I've since done 20k miles with no serious problems but if using 5w/40 is going to encourage further problems then maybe i need a set of new lifters. Link to post Share on other sites
