First of all, you do not have to go 5W40 per se to get thick oil that will do good with potential fuel dilution.
You want oils that are approved for European manufacturers (ACEA A3/B3 B4, and reason for that is that Euro manufacturers have more stringent oil requirements), oil approved for MB 229.5, BMW LL-01, VW 502.00 Porsche A40 (only W40 oils). You can also go lower SAPS oils (ACEA C3) that were some time ago primarily designed for diesels, but with drastic drop of sulfur levels in gas in Europe in 2009, and the US in 2017, they are also good for gas engines (and much better for catalytic converters). You can use anything that has MB 229.51, BMW LL04, VW 50400/507.00 approvals.
Now, reason why I am saying approvals and not specific grade is that all these oils must have minimum HTHS of 3.5, and they are usually thin W40 or thick W30 oils.
Readily available oils? My choice would be Castrol Edge 0W40 in Wal Mart that goes anywhere between $22 to $28 (5qt jug). Same goes for Mobil1 0W40, alo in Wal Mart. You can get Castrol Edge 5W40 in Wal Mart for same price, but it is step below Edge 0W40 or Mobil1 0W40. Valvoline European Vehicle 5W40 is an option too.
If you go with C3 oil, you can find Pennzoil Platinum Euro L 5W30 for $22 in Wal Mart.
Online you can find bunch of other options, but Castrol 0W40 and Mobil1 0W40 are go to oils for owners of Euro vehicles and they are dealing with turbos much, much longer.
I'd go with Mobil1 0w40 right now, get two jugs, and submit the $20 rebate for them make them about $15 per 5qts after rebates and taxes, great deal for Euro spec oil.
