This spider seems to have had some of it's legs surgically removed.
The leg for 'cost to the consumer' is strangely absent; probably because it was fat and ugly.
The leg for benefit-to-cost ratio has been amputated; probably because it was horribly withered.
The legs for outrageously high volatility, oil loss, deposits and premature oil darkening cause by oil burning, late onset excessive oil consumption due stuck oil control rings were chopped because they were frankly an embarrassment to look at!
