I could not confirm the ISO 46 stuff is good enough, although it's reported to work fine. It does not meet the referenced spec; Mil-H-5606. Also it is 20wt where 15wt is specified for the MB system. Does it matter? I dunno, but I didn't want to go that way. People report using it and it's definately cheapest at about $10-$13 a gallon currently.

The Shell Aero is 1/2 again more expensive from what I could figure (still cheaper than Febi stuff). I couldn't put my mitts on it quickly at the local aeropuerto, and I didn't need the aviation spec anyway. Much less the -100 degree F rating. The Glacial blu is only good to -60 F, but I think I'll risk it.

Here's one of the links I read about this product. (mis-spelled as Glacial Blue)

Member strelnik discusses the product at $8.50 a gallon in a 1 year old post. Hah! Now I got it 'cheap' at $17+ a gallon. So I would double check on pricing. An auto parts place in AZ has Febi for 10.50 a liter, the cheapest I found. (my local indy shop is higher). So $40 Imp. gallon (at cheapest) vs $17 for Kendall Glacial Blu US gallon. I wanted to be able to flush it out again in the future, so buying 5 gals was still cheaper than buying 2 gallons of the Febi stuff.
