There is NO corn likker available within almost 60 miles of where I am, so no, I cannot use any ethanol, and when I eventually get a Monster Tune, I probably will not even ask for an optional E30 tune at all.
I switched to the LiquiMoly Molygen on this current oil change interval, but I am thinking of going back to the (yes, $$$$, even more than the LM stuff!) Ravenol DXG next change, due to it's guaranteed PAO base stock use (with maybe even some POE esters thrown in for good measure??), slightly better starting TBN, innovative tungsten and trimer molybdenum additive package, and much better, very low volatility rate.
The latter is desirable not just if one is using ethanol, but even for any gas turbo direct injection setups like ours, in general, even on 93 E10.
I do wish that BG included the starting TBN on the specs above.
I do not bother with any oil analysis since I do not do extended oil change intervals (even on great oil which is fully capable of that), try not to let the car idle very long, typically do not drive in much stop and go anymore, and run factory heat range plugs on a factory tune, so I'd rather just put that coin into the next oil/filter change coffers.
Basically though, unless you are doing A LOT of stop and go commuter traffic, very short tripping, or idling constantly with the E30 in the tank, changing out any good off the shelf top tier readily available and affordable synthetic labeled oil (even if they are really a Group 3++ super hydrocracked/Visom, or GTL base stock, and not a 'real' synthetic Group 4/5) before 3K miles, you have nothing to worry about.
The Pennzoil Platinum ULTRA seems to be very good stuff, as it's GTL (gas to liquid) base stock is very durable as far as shear and dilution go, and may soon prove to be as great as the Group 4/5 PAOs and POEs.
Better than average additive package as well.
The problem is it is only sold at the auto chain stores (where it is sometimes included in their sales), or via the internet from Wal Mart, NOT on the shelves at Wal Mart.
