Thank you for this. Just ordered Castrol Edge High Mileage 5W-30 for my 150K 2004 Sienna. ~$21 with tax, delivered.
Put 5000 miles on the van since I bought it last October. The PO did nothing, no maintenance whatsoever, except for religiously changing the oil every 5K with synthetic blends. The car used about 1/8 quart of oil over those 5K miles I put on it and that included a recent 2K round trip with the cruise set at 80mph in upper-90° temps, A/C running full blast.
Can't beat an old Toyota.
