@ margallar - greases should never ever be mixed with any oils, the soap may not accept the oil and eventually will completely break down the grease into a runny mass that will destroy the item in short order, the LM grease you show is made for CV joints and will last a very long time.
Do not overfill the joint, weigh out about 90 grams and use it per side, it may seem low but its enough as the centrifugal force of the spinning axle will cause the grease to roll in the joint - which is exactly what you want. Make sure all traces of old grease are removed first, wash with kerosene petrol mix and dry with acetone for at least 15 minutes before repacking the joint.
@rizkhan - if your joint has started to click and the boot it not ripped, remove the joint immediately and fill with correct CVJ grease like this LM product. You can also buy it of other brands, The Fina lube bucket of 5 kg I had was good for years. One car outer joints take 180 grams only for both sides.
Please note that you dont want this grease in spider type tripod inner joints because the rollers spin at high speed within the spider bearings and the moly in the grease can separate out and cause dragging. A 1-5% moly content NLGI2 li-complex Exteme pressure grease with adhesive and smooth texture is good for that purpose, Or even no moly content but very impressive loading spec grease will work.
