    So my new fancy temperature gauge in it's first day of use ran at about 165-175 on cool rainy day highway driving to work. Idling at a drive through put me over 230 though, so, I think my fan isn't engaging correctly. What temp should I consider setting a warning alarm at to be safe?

    My personal preference is to have the fan kick on at 195° or 200°, and turn off at 185° or 190°...

    Happy accident?? Hardly.

    The fact Mobil 1 states SL & SM in their PDS indicates it's fine in gas engines. I use the current gas oils in my two valve 4.6(s), but those are geared toward fuel efficiency, thin out when hot. Which is exactly what I DON'T want in my oldies with wide clearance margins. Luckily I'm free to use what I want and so are you.

    I put AMSOIL Z-Rod 10W-30 in my 302. Once I fire it up and get it going, I'll let you know how I like it.
