Hi, I do what others have said and that is via a funnel and hose to the fill plug. What I do extra is to remove one side bolt from right at the top of the banjo , this allows air to escape, otherwise with such a vicous product, it takes forever.
how bout a 10' extension to grease the chassis, this way we wont ever have to get under the car... and we can change our oil like a boat motor and suck it out
