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).
