I have a Tiger with a Boss302 engine fitted.
I was going to use standard 20/50 oil as per normal, but the dip stick says use 101-b spec oil to maintain warranty.
Can anyone shed a light on this ?
thanks

Jeff > I too have a Tiger the is fitted with a True blue , Canted Valve Head Boss 302 . I run Kendell 20/50 Racing Oil . Never heard of 101 - b spec . I heard rumors that Ford offered Boss owners a swap out dip stick not much after taking delivery . The new stick had a different level marking , whch added like 1 qt. more to the capacity . Yours may be the first design , original . Mine does not state that "Use 101-b spec Oil" on the stick . But mine is a swap out .
Hope this helps .
