The blue one is pretty but I'd worry it might be too thin for my cars. I'd be afraid the red one might stop the oil leaks that I consider absolutely essential to a long lived car in my area. The gray one looks a bit drab, but it's the one I'd take home.

Good price for it, ya?
Me, myself, i would go with Blue first choice (lubricity) then consider the Red.
My logic: We have two variatons on basic motor oil.. 1. Synthetic, and 2. High Mileage. Now, it seems that Synthetic is usually not "needed" in most apps the same way CATERHAM says thick oil is not needed. So, that leads me to High Mileage.. seems maybe the blue might be the way to go? ? ?
Thoughts?
EDIT: yonyon, I actually went against my own logic and got just a quart of Full Synthetic ST 10W-30 (not 5W-30) since its all they had on the shelf. Topped her up and she runs a-smoothly. The Full Synth is good stuff!
I would have spent the extra .30 and gotten the jug of QSUD 5w30. And then sent in the rebate (if that is still going on) and gotten the 5 quart jug for about $3.

Which is what I did last month.
I agree - but my answer would be it all depends on what the engine is and what type of driving and intended oci I intend to do.

Its the 03 Envoy XL, 146,000+ miles. I really want to go with the 0W-20.
If I am unsuccessful in my argument, its going to get whatever "bulk oil 10W-40" is over at the shop.
I topped it up ST full synth 10W-30 (5W-30? I forget) and, both being thinner than whatever 10W-40 is in there.. feels better. Also the 10W-40 is conventional not synth.
By the way: Thermostat is done, engine at 192 degrees.. and it feels better, noticeable, than when it was overcooled at ~160 due to failsafe failed (open) Stat.
Remember.. this truck gets "turn key and go." Every time...
