How similar are ESP 0w-20 and 0w-30?

Guys, AFE 0W-30 looks like an awesome oil. I think I want this instead of PUP 5W-30. I am doing a VOA on this

So many approvals
Most of those are API. They could have simply listed SP, and it would’ve covered the prior ones as well.

For the Ford approval, I’m not sure how stringent it is. But, I’m not sure I could find a single example of someone being impressed by it.

AFE is a fine oil. But, there’s no way we can tell that it outperforms the ESP variants from that list of “approvals”.

ESP is great, but AFE is thinner and better for nervous me trying a 0W-30 on my lil Jeep. It is the most 5W-30-like 0W-30 I have seen, others are so crazy thick.

Not sure I would call them crazy thick. The Mexican owners manual for my Frontier allows for anything from 0w-20 up to 20w-50 (extra super crazy thick?) as long as the winter rating is correct for your expected ambient temps.

Good ol’ USA OM only recommends 0w-20. This was purely a decision made to appease the EPA.

Same exact engine.

Maybe they did a slight change in the engines that were sent to the US
 
Nope. Same exact engine.

If they did, what magic they use on the Mexican variant that allows 0w-20 up to 20w-50?

Do whatever you need to do so you can sleep well at night, and have dreams of the “perfect” oil viscosity. But, don’t incorrectly convince yourself that a change from 3.0 to 3.5 HTHS is “too thick.”
