i respect your opinion on what "full" implies on a bottle of motor oil;however i don't think api had as much to do with "full" on a motor oil label as did a judge.while you and i may understand why group-3 is often referred to as man made the average consumer is totally un-aware. the"small print"is much too small.the prolongs and slick-50's of the world have been spanked for misleading consumers by false claims; do you really feel it is ok for motor oil producers/marketers to imply that because their product claims "full synthetic" on the label that there is some magical element inside? and because of this magical ingredient they can surely use this oil for up to 50,000 miles as is touted by several "full synthetic" marketers? my lay opinion is "all marketers of synthetic lubricating fluids should display on the label either front or back, exactly what % of synthesis creation is in that bottle.it is done with other consumer products, whiskey,wine , fruit drinks, all express what % of alcohol or real juice is contained within.i have no war with synthetic fluids,but playing with words simply for personal gains is wrong.kind of like the guy who looked into the tv camera and said"I DID NOT HAVE *** WITH THAT WOMAN",all because of his opinion of what the word *** should mean.
