How to avoid cheating while buying motor oils
- WHENEVER possible, buy nationally known brands of oil and gasoline from stations of known repute.
- Specify oil by name.
- See that attendant gives you the kind you asked for.
- Note that the measure is entirely empty before attendant fills it.
- Check crankcase level after each oil Change.
- If oil is suspiciously muddy in appearance, check for gassy odor.
- Don't assume oil to be good merely because of clear color.
- Don't leave car at unknown station to be "gassed and oiled" during your absence.
- See that bowl of visible-delivery type pump is full before filling car tank.
- Steer clear of "big bargains" in gas and oil.
