"API viscosity ratings for gear oils are not directly comparable with those for motor oil, and they are thinner than the figures suggest. For example, many modern gearboxes use a 75W90 gear oil, which is actually of equivalent viscosity to a 10W40 motor oil."


Several instances around this forum, people use a specifically designed oil from Europe in the getrag, with the 5w and 10w40 euro spec oil (which is for motorcycles) which is used in both the engine AND transmission. Since mines a DD, I use the ford honey.

Both from Amsoil
