I am not going to unpack everything you wrote here, because it would be impossible to address that BS in any meaningful time.Mobil 1 0w30 AFE is API SP and will meet many approvals for small displacement turbo charged engines as it passes lspi tests. ESP approvals are more from cars that have v6 engines.
I will just say, that whoever is trying to get some advice here, should avoid your posts like a plague.
You are talking small turbo engines. Those engines are used in Europe since 1989. These approvals ESP has are designed precisely with small turbo engines in mind.
Afe is ILSAC, energy conserving oil.
ESP is DERIVED from C3 specification (which is regularly updated!!!). It is not energy conserving oil, it is made out of much better base stocks, has far lower Noack, obviously higher minimum HTHS, etc. Because it is C3 and has numerous other approvals, it is “stay in grade” oil, meaning that for example bcs . it has MB229.51/52 has to be able to stay in grade in MB engines recommended for that approval, or VW504.00/507.00.
Personally, unless absolutely necessary, I would not use Afe 0W30 (unless too cold, like -20 and below), but 5W30EP.
ESP is not necessary in engines such as 2GE-FE or FKS. But, if price is similar to Afe, yeah why not.
Where I would definitely consider ESP are new turbo engines in Toyota/Lexus.
