Statistically they all look the same. The only conclusion I draw from this analysis is that the 1.8T is one heck of an engine from a materials perspective.

Also did the test for lead comparing 30 weights to 40 weights (all samples, not just the mobil 1 samples) and found that 40 weight lead is significantly lower than 30 weight lead only at a 13% significance level. But given the small sample size, this isn't bad so you may be on to something Patmanquote:

Looks close to me on most things, but bearing wear (lead) is greatly improved with 40wts! For that reason, I'd go with the 40wt in those engines for sure.
Thanks...guess I need to root for the Buckeyes today, huh?quote:

Thanks for your thoughts TooSlick.quote:

VW and Audi don't specifically recommend 10w-30/10w-40 for their current crop of engines, but that's tied to saving 0.5% in fuel efficiency with thinner grades. Unless you live in Alaska, a 10w-30 or 10w-40, PAO/Ester based synthetic will provide excellent year round performance.
Hmm, so you'd rather use an oil that doesn't meet the VW-mandated minimum requirements to begin with?quote:
Like most 1.8T drivers, I've been using Mobil 1 0w-40 since it became readily available but will be switching to Mobil 1 5w-30 and 10w-30 for better shear stability.
AMEN!quote:

Mobil 1 0w-40 meets VW 502 but according to some UOAs here, it's not as shear stable as 5w-30. For the rest, I'm aware of them but they're not easily available and more expensive. I rather spend that money on other mods.quote:

There are a few 5W-40 oils available in the US that meet VW 502.00:
- Pentosynth 5W-40
- LubroMoly Vollsynthese 5W-40
- Unocal 76 Pure Synthetic Oil 5W-40
I don't think Redline 5W-40 would harm your engine either.
