octaine
I have a 99 f-150 and I use 87 to 91 octaine.
I find that the 91 is the best but if I use more it runs even better. How much should the 4.2L need?
------------------
99 XL 4.2L, 3.55 Limit slip, Alum. rims,
Captins Chairs, Long Box
Headlight covers, Master flow muffler,
It is one hard working truck!!!
