Yah i looked into the fumoto. Did you have a part number for that blizzard? I thought i saw on here that the model number changed?.
Ill definately be doing my own oil changes again now as my two years of free changes is up so the fumoto woul definately be nice to have.
From the looks of that metal that rusted out, its definately a low grade metal like they use around the cats etc. probably great at dissipating heat and cooling off quick but crap for longevity. Any ideas what you might do for a coating? Powder? Not sure what the temperature limits are on that but might be worth a try. Its definately a tough spot given the high heat.
