HUH??? This doesn't enen parse.
EITHER the US Dollar is weakening... and this is defined by its ability to purchase overseas goods ie the exchange rates - not any particular specie pricing
OR it is NOT Weakening.
If the dollar is Weakening (which no-one disputes) then FOREIGN currencies would necessarily be paying LESS for Dollar Denominated commodities (like Oil). Consider the extreme example: The Euro gains 10x vs. the US Dollar. That means that Every Euro would convert to $10. So E$10 would convert to $100 or 1 BBl oil. Since Oil WAS trading at E$80/bbl
http://economy.hidepark21.org/Oil.htm that would mean the price of oil in Euros would DROP by $70/bbl..
Now since Dec we have seen a 3cents/76cents decline in Dollar/Euro value
http://www.advfn.com/p.php?pid=qkchart&symbol=FX^USDEUR - or about a 4% dollar value drop.
And the price of oil has gone $101 to $107 in the same time period

Using your logic about the weakening dollar, The Dollar equivilent in Euros should be about $102.72/bbl of crude which after the conversion rate is E$78/bbl
Yet in March the Euro crude price is
http://economy.hidepark21.org/Oil.htm E$92/bbl. Or 20% above what a weak dollar slide would predict.
So explain how a "weak dollar" that is "losing value" against other trading currencies, is a better means of purchasing Oil than the currencies it is "sliding" against?
There is a simple answer to this... the change in the price of oil HAS ALMOST NOTHING TO DO WITH THE DOLLAR VALUATION SLIDE.
Now we have already addressed the bogousity of this particular piece of Forbes Bloggery (its a blog piece not journalism). The very notion that a currency tied to the US Dollar changes in its purchsing price of oil WRT the Dollar is itself ludicrous. Yet that is what your little article claims
GO DO THE MATH YOURSELF. stop regurgitating echo chamber received wisdom.
To see more clearly how the price of the dollar has changed, it helps to view price changes over a 10 year period. Since 2002, the price of a barrel of oil has increased four-fold, to $107 last Friday from $26 in 2002. To suggest that oil companies had enough power to impose such a price increase, or that speculators are responsible for a quadrupling of the price of oil is, on its face, preposterous. Instead, the price of oil and gasoline are up because the Federal Reserve has driven the value of the dollar down.
For example, if the dollar since 2002 had been as good as the:
• Chinese yuan, the price of oil today would be $82 and a gallon of regular gas would cost about $3.10;
• Euro, the price of oil today would be $77 and regular gas would cost about $2.90;
• Japanese yen, the price of oil today would be $71 and regular gas would cost about $2.75;
• Swiss Franc, the price of oil today would be $63 and regular gas would cost about $2.50.
Even these results miss the full decline in the dollar’s value because the value of all of these currencies, too, have fallen over the past decade. If the dollar had been as good as gold, the price of oil today would be about $20 a barrel, and the price of gasoline would be down near $1 a gallon. That’s right, the lower prices produced by the increase in oil and natural gas production have been disguised by the fall in the value of the dollar.
