My Dad changed the
oil in the family cars each 6 months. He religiously topped the
oil up with an additive in a tube called 'Molybond' or similiar.
He took the old
oil out of the cars and then did an oil change in the motor mower with the old oil.
..like him the motor mower is old, but still going strong. Now 'Molybond' may not exist today, but hell he used it all the time...
.. even in the diff and the gearboxes...
Alvin, don't forget to do the filter and fill it with oil as you put the new one on. Then I'll bring my car over and you can do it also..
