Allis engine are low pressure oil type engines and if it has numbers on the gauge then it has the wrong gauge on it. But yes 10psi is good for one. A true Allis gauge should not have numbers but have a normal range and a low range sort of thing on it. The engines get oil pressure by way of the oil filter and the wrong filter will cause major problems and no PSI
