Is Walmart's Accel 30 Wt Non Detergent oil safe to old mowers?

Is Walmart's Accel 30 Wt Non Detergent oil safe to use in old lawnmowers? I wanted cheaper general-purpose oil but that is usually a 30 Wt High Detergent oil. The Wt I had right but I missed non-detergent until I started a mower's oil change today. I have never owned a new mower or tried to find a manual's specs vs using 30 Wt HD since 1973 in 3 mower. I managed to find a new qt of 30 Wt HD Castrol in my stash (probably 20 yrs old, LOL). Now I wonder if it would have mattered for my once a year oil chance.

The only qt of non detergent 30 wt I have specifically purchased was to oil wics in my AC/Heat Central Unit's motors (1970s per the installer).

Non detergent is not suitable for an engine, the detergents break down the contaminants from combustion. Save it for pressure washer and air compressor pumps.

It's hard to find (impossible maybe?) a non detergent oil that has the proper anti wear additives.

I like the older Diesel rated oils because they have a good anti wear "package" and don't tend to eat flat tappet cams. modern oils are designed for cars with roller tappets and have a different additive package.

My 2 cents . Non Detergent Oils were the norm for lawnmowers and snowblowers for years. Normally these units do not have filters . I would not recomend these oils when you can have the dispersent additive reduce sludge and dirt , while rust inhibitors (alkaline) reduce the oxidation potential which occurrs when acidic oil becomes an issue. In an emergency sure but why save a few cents today and pay $ later ?

The bottle clearly states below basically what has been shared. I'll use it as a gen non eng application.
