I have found the additives in some oils drop out of suspension in long storage. I just had this with 5 tins of Motul 300v 10w-40. MTF has a specific shelf like (normally 3-5 years). I had a nasty surprise with VW MTF that I kept for 6 years, when I opened the bottles the additive had dropped...

Another thing that helps me choose between 5w30, 5w40 or 0w40 is the operating oil temperatures. My rule of thumb is this: consistent >100C = xw-40, 100 or Factors like fuel dilution, external temps and motor age should also be taken into account.

Originally Posted By: artificialist I would not take the chance. The VW DPF engines need 507 oils, and if the DPF fails under warranty, you might be denied the repair. DPFs are very expensive, don't take that risk! 507 oils are a lower viscosity, however, what makes them much different is that...

Check this out, I done see VW making it only DI... http://www.vwvortex.com/news/volkswagen-...LLCC=2986168441 GTI fulfils Euro-6 emissions standard. As noted, a dual injection system – with direct injection and multi point injection – was also implemented to conform to the Euro-6 emissions...

So regarding the G7 Gti, 1) they run higher lube temps than previous models due to VW's thermal dynamics studies, where it was found that they get better economy and power when running dual thermostats (one for the head and one for the block). 2) These motors do not suffer value deposits like...
