No, synthetic usually finds its way through even smaller gaps and can thus leak/burn more in an engine that is already losing some oil.
Without a true synthetic requirement (manufacturer's declaration, extreme cold temps, extreme duty or very long OCIs) I'd say stick to what you're doing. Any current API-rated motor oil exceeds the specs that were in effect in 2006.
You might as well stick with the cheap stuff since you'll be buying more of it.
