Go mail order. Amazon brought me a sealed box of Eneos a while back in 2 days, free shipping. Easier than being emotionally wedded to "gotta be on a shelf".

It's twice what you say. ... Going from HTHS 2.7 ---> 3.5 means 4% difference in power and fuel economy. ... Over a lifetime of 200,000 miles, that means about $1,000 more in your pocket & more peak power available. For that, there might be about 5%-10% difference in iron wear. Very little difference in wear.
The ONLY time I can think of when you need to go up about +0.5 in HTHS is when you are racing or towing, or have known fuel dilution problems. Otherwise, it actually makes more sense to go with the manufacturer's HTHS recommendation in the Owner's Manual. .... Imagine that, trusting the maker's engineers for this !!!
Only problem with your thinking is that EA888 is built around heavy oils, and that they are STILL running on VW504.00/507.00 STRICTLY in Europe. Only reason why VW508.00/509.00 is recommended in US is CAFE.
If I was buying brand new VW with that oil in, I would tell them right there in dealership to switch to VW504.00/507.00 or VW502.00 before I take out car.
Exactly.
