If a synthetic oil is advertised as "fully-synthetic" or "made from 100% synthetic base stocks", I am assuming that it really is a fully-synthetic product versus one advertised just as "synthetic" where they can get away with using mineral stocks also. Correct?

Also, even though synthetic oils last longer and can be changed less often, is it a good idea to continue to change the oil filter at the recommended intervals? Afterall, the good fully synthetic oils deal with engine sludge and contaminants better than petro based oils, but they do not prevent them from forming, so you still have to filter them out.
