Cold start with chip

[Shea97Stroker]

Is it bad to cold start my truck on the TW extreme setting? I always have the extreme setting set when I start the truck

[outlawdiesel]

I would say yes and no. If your running 15/40 oil then yes. the oil is to thick when cold. but if your running 5/40 them no. but you might want to set it down one or two cause the timimg could be way out there and a cold head gasket. well you may want to set it down alittle and let it warm up then switch it? my 2 cents

[Shea97Stroker]

yea I run 15/40 shoot Thanks for the reply though I guess I'll let it warm up before switching it over from now on.

Move down to Southern California. It's doesn't get cold here Why don't you just call or E-mail TW with this question then get back to us with the anwser.

Me to. Well u never wanna rev up ANY motor for that matter when its cold anyways. Things are brittle when cold, i.e valve springs

I would think you would not want to start on the extreme seting. It might be hard on the fuel lines and seals when they are cold and brittle.
