[jeremy 2]

hey guys just wondering what everyone else is putting in their m40b18. I've been putting in 98 but am i just paying for no benefits? what does everyone else use?

It's all the same, I just use diesel as it's cheaper

Your car will be fine running on 95.

I run my M40 on a mix of kero and head gaskets

91.  It doesn't run as good, but I'm tight.  really, totally, scotsman tight.  so 91.
