Rotella T, in T4 15w/40 still has plenty of ZINC in it, funny part is, when we build motors, we only use Mellings cams, but if you get a comp cam,
engle cam, mellings cam etc..., they all come with the same little yellow paper and it says, USE DELO. DELVAC or ROTELLA, but if you notice, the T4
has the most zinc
