    Friction Modifier Question

    I'm getting ready to swap out the factory diff lube in my 07 GT. Has anyone had experience with Lucas synthetic 75W140 without adding friction modifier? Lucas says its not needed, but Ford recommends it in the manual. My thoughts are to add it, but I'm wondering if it could get "too slippery"...

    Diff Lube Change Question

    I'm planning on swapping out the rear end lube soon on my 07 GT and was wondering if anyone has had experience using the Lucas synthetic 75w140 without the friction modifier. It appears that a lot of folks have and haven't had any cornering chatter problems from what I've read and Lucas...

    Exhaust Winter Storage Of My '07 Gt

    I think there are 2 schools of thought on periodic starting of a car that has been suitably prepped for a long winter sleep (necessary here in MI, if the car hasn't seen winter ravages).... Any thoughts on the downside of an occasional 15-20 minute start and idle as opposed to leaving it rest...

    Engine Plug Swap on a 4.6 3-V

    Trans oil in my 07 GT with a manual 5 speed

    The owner's guide says to use 'Mercon', which to my understanding is Dexron III in the 5 speed manuals....anyone disagree with using Mercon V?:shrug: I see that Ford has switched over to that spec in the steering systems. It should be as good or better for the trans.

    Storing my '07 GT for the winter

    For the last 2 winter bed-downs (11/15-4/15), I filled the tank and started it from time to time, and made a rare trip out on a dry day without any noticeable ill effects from 'stale' gas in the spring. The owners manual says not to use any aftermarket additives. Any thoughts out there on the...
