Given the intent to OCI at moderate amounts, I'd say you're not going to get any ROI from the syn. Plenty of dino oils can easily handle 5k-7k miles with the same results for less cost.
I am not sure that there is no benefit, assuming that there even exists a conventional 0w20.
If a synthetic will get just 1% better gas mileage (that is 1%, not 1 mpg) than a conventional, and you run it for 7k instead of 5k, you'll go 70 more miles than the conventional. Depending on your mpg and price of gas, you could approach break-even.
Not to mention one's time crawling under the vehicle.
I'd stick to synthetic. Plus he has to anyway if it calls for 0w20.
