Shell Full Synthetic 10W30 at $3 per quart

I have a coupon for BJs for Shell Full Synthetic 10W30 at about $3 a quart. This very low price tempts me to give it a try. Shell is a well known name, and I assume their synthetic is as good as any, am I right?

I have a 2004 Forester with 45,0000 mile, a 2005 Chevy Colorado with about 14,000 miles (yes, that low), and a 2009 Suzuki SX4 Cross-over with about 2,000 miles.

All have had only dino oil, usually Castrol, but not always in the older car.

Is there any problems/disadvantages for moving to Synthetic on an engine broken in on dino oil?

My vehicles are all 4 cylinder and all specify 5W30 oil, I think for "less friction" from the average lower viscosity.

I could buy the sale priced synthetic just for my garden tractors.

I have had very good service form cars run on brand-name dino oils, and don't see why I should go to synthetic. As can be seen, all my vehicles are low mileage, so if I change oil only once a year I'd still be changing long before any extended oil change interval that might be acceptable with synthetic. I think one should no run an oil more than a year even if the annual mileage is low, say under 5,000.
