I would chalk that up to a new form of internet hysteria. Yes, the overdrives do work better with normal GL-1 rated gear oil but synthetic oils are not the overdrive equivalent of ebola virus.

Besides, when the car is operating in overdrive, the rollers are not transmitting power and just coast along in their little cage.

If indeed your OD is absorbing a lot of power then it will quickly get very hot, so it would be wise to check it but that is quite unlikely. I would do a careful timing check first, then have a good look at the air filter and carb after that.
