Thanks Benito, I hadn't seen that yet.

Correction, that's a KV40 of 20.8cSt.

I thought you recently said you didn't have a Shell distributor near you? See what price you can get on some PP Euro LX 0W-30 for the G37. I can't think of a more suitable engine lube in your climate if you must run a HTHSV 3.5cP oil. The fuel savings alone should make up or the higher cost...

Off topic, but what happens when a so-called conventional is actually 100% synthetic? Does that not present some psychological issues? Or is the real love affair with the least expensive oil that should do the job? BTW PYB is on sale at Cdn Tire for $4.5/qt.

Ah, the master of obfuscation at work. That's fine you can use all the cheaper to formulate low VI oils out there; someone has to use it. BTW chasing Noack volatility is very much a mug's game. Implying an oil with a still excellent 9-10% Noack WILL thicken oil is of course nonsense. A Noack as...

Yes that is a very low Noack number, lower than VW requires and of course we don't know if it translates into any actual deposit benefit. So it comes down to whether you want the advantages of a 0W oil with a 40 point VI advantage (204 vs 164) or not. Mobil's ESP 0W-30 isn't VW certified so...

Since PP Euro LX 0W-30 is a GTL based oil it's inherently superior with a higher natural VI and therefore likely doesn't use any more VIIs than M1 5W-30 ESP and we know based on company cert's that it's Noack will be less than 10%. Your shear stability index is a poor predictor of actual shear...
