Does $n$-power-associativity, for $n$ big enough, imply $n+1$-power- associativity for $m$-dimensional algebras over a field of characteristic zero?

Let $F$ be a field, $Char.(F)=0$ and $n$ be a natural number. We say that an algebra $A$ over $F$ is $n$-power-associative if $n_{th}$ power of any element is well defined. Is it true that there...
