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

Yes. It will explode. I would drive it with a bulletproof helmet just in case the rod bearing finds its way through the dashboard.
I think we covered this like 183683683 times.

I was thinking about the add pack or chemistry not a thick vs thin issue.

Both are emissions-friendly. Both have I think same SA limits.
There will be some differences bcs. grade in VI etc.

Really solidifies for me that ESP 0w-30 would be my choice if VRP did not exist.

I know that both contain esters, gtl, pao. According to Mobil’s product sheet, the 0w-20 flavor has slightly more phosphorus and zinc. Are the other additives pretty similar? I know that 0w-30 has a much higher HTHS.

Compare the approvals, instead.

consider the Mobil 1 AFE 0w-30, sort of in between viscosity's , its the only Mobil oil I would use. in a newer vehicle.

That's what I've been thinking about using in my Jeep.

Why? It’s a thin 30 grade oil that shears heavily, and carries fewer approvals than either ESP oil. Nothing wrong with it either, and I’ve used it. But it’s far from Mobil’s best oil.
