What are the pros and cons of using diesel oil in a gasoline engine? I know diesel oils has more additives and detergents and such, but is that the only reason?

Pros: more ZDDP.
Higher initial TBN
Lower cost due to less marketing.

Cons: higher ZDDP (not good if you are a frequent oil changer and have emmissions gear, but probably not an issue if you do extended drains).
Typically only available in heavier viscosities.
May not be readily available.

Pro: Thicker, most are 40-weight, even the 30 weights are heavy within the grade - may help consumption.

There is a 10-30 available, but that is the thinnest I've heard of.
Normally 15-40 or 5-40.
This is a bit thick for modern cars. Not a big deal in Summer, but cold starts in winter will suffer -flow and drag.

I think if they had a5-20 and 5-30 HD oil, everyone here would consider using it, otherwise.

How about the magnesium additive; that is usually not in PCMO, mosy likely for a good reason. Will that Mg (?) compound cause some issues?

Castrol syntec 5W40 is loaded with Magnesium. As I remember I saw on the order of 700-900ppm on UOAs.

Hi,
saaber1 - "Magnesium" is typically used as a detergent. It is being replaced in some HDEOs by the more expensive "Calcium" products

HDEOs that are not endorsed "mixed fleet" and carry dual petrol/diesel API/ACEA Quality ratings should NOT be used in petrol engines. This especially applies to those with a very high TBN due to their likely SA levels

What about SAE 30 in an older model vehicle that calls for 5w-30?

Just want to clarify your statement... Are you saying that, if they do not say "mixed fleet", even though they may be SM rated, they should still not be used in a gasoline engine?
