As far as I could tell, there was no real difference in how fast they flowed or how “viscous” they appeared. This leads me to believe that any reasonable grade of motor oil would serve the purpose.<br class=""><div class=""><br class=""></div><div class="">But keep in mind that the ambient temperature was 85º F. Now think of your poor carbs in a cold garage in Maine, or Wisconsin, in February. I am wondering how stiff the gear oil would be under those circumstances.</div><div class=""><br class=""><div class="">
