What is the effect of wear on viscosity flash point,fire point of gear oil?

if we are using a four wheeler then what will be the effect of wear on the viscosity and flash point and fire point of the gear oil.whether these will increase or decrease with increasing wearWhat is the effect of wear on viscosity flash point,fire point of gear oil?
The viscosity of your base oil never changes. What does change and wear out is the additives in the oil which prevent foaming, rust and resist pressures from loads. These additives break down and wear out. If you run your gear oil too long or too hot then your mechanical components will wear out.





Flash point might be affected as the additives become depleted. If you are worried about flash points then a synthetic gear oil is your best choice and I would not consider using a petroleum based product.





Gear oils made for racing purposes offer vastly superior protection than every day conventional products
