It doesn't sound like claims are being made. Some wicks, I've found (like Eco's, for example) work MUCH better than others in burning tougher oils and/or higher levels of fragrance load. Maybe it's the wick construction but, Eco's seem to be the ONLY wicks that have burned some of my tougher, higher load oils/candles without drowning (and I've tried every wick under the sun...haven't tried these Aroma Lite ones yet). But, I don't think they are making claims. Just simply that maybe because of their construction they are able to burn tougher oils. Call them up and ask for some samples. They are usually pretty generous.
