Lake Speed Jr. ... Diesel vs Gas oils

[kschachn]

Last I checked the ESP 5w30 was SP. The ESP 0w30 isn’t because phosphorus is over the 800 ppm limit. I’m sure someone will correct me if it’s changed.

Which is a feature, not a bug (in my book).

Delvac 10w30 and 15w40 are both SP licensed.

That should suffice to establish OK for gasoline engine usage in the majority of instances.

If HDEOs cause elevated wear in gasoline engines, they would also elevate wear in Diesel engines,

Complete fallacy. You are assuming they have identical sources of wear and aggravating/mitigating factors. Agglomerated soot is not a factor in gasoline engines the way it is in diesels. The very additives in diesel oils that target soot management are make those oils less capable where soot loading is not a factor.

Note: less capable just means less capable, not harmful or “bad”.

A logical fallacy is a flawed argument that may sound convincing but is not supported by evidence.
