G'day All,
The way I look at the oil ratio is if you spend normally around $10 a litre it's going to be 25 to 1
and if you spend around $20 a litre then it's 50 to 1.
Yes I agree ,shutting the motor down from the tap ,possibly the engine will only last 29 years instead of 30.
I know of other people that have turned the engine off from the tap for 60 years and haven't had a problem.
If you live in colder climates I can see the motor internals could rust if left dry from stopping the engine from
the fuel tap.
