i have the hose hooked up and am going to inject 10 mls of full synthetic, this is fine correct? and how often do you guys do it?[/b]
It is not absolutely necessary to inject oil in the center bearing of an '07 440 but it definatly won't hurt anything, in fact it will likely make the motor last longer. If it were mine and I wanted to squirt some oil in the center bearing cavity I would inject 5ml every time I refueled. 10ml would work too and 10ml wouldn't be excessive or hurt anything.
