Multi-grade 10W/30 is the best oil to use, anything with a higher grade than that is no better than the outdated GL1 type oil. Multi-grade is much better in cold conditions as it does not get as thick as the GL1 type. The Multi-grade is a much better oil as it has a higher specification regarding anti-wear properties and you can use it all year around no matter where you are. Hot or cold climates does not make any difference and it was recommended by the suppliers of oil to MF as a direct replacement for the GL1 type which now is outdated for how we use it in these tractors. Anyone in a cold climate will notice a difference straight away, only those in a moderate or tropical climate will not notice much difference until you have to repair the hydraulics or transmission. Hydraulics need a relatively thin oil to operate successfully, thick oil will slow the movement of the Control Valve and when it is really cold it will prevent it operating, but because you are using the same oil in the Transmission, you have to compromise on what oil you do use, Multi-grade is much better all-round. We used Multi-grade in the tractor from when it was introduced in the UK in 1955. Just because it was written in the Operators Book for the Tractor 50 or more years ago, does not mean that you should continue to use the GL1 type when there is something much better available.
