Thank you Michael,
I belive Kamoil was a very thick oil, as in the Instruction book they says 90 EP can be used.
I think Penrite is semi liqid-grease, but i belive the Miller is thick oil. As i wanted to stick to factory reccomandation i have ordered the Miller in the end. As soon as here i will be able to report on it.
I want to change it as i am changing all the fluids and greasing and oiling all the car.
I agree with you that the steering box lubricant is not something that has to be changed regularly, but even if what is in the car looks fine and clean is probably in the car since 60 years!
i could top it up, but i dont know what is in there, this is why i was planning on changing it all.
I dont want to mess with the steering box either, so my plan was to siringe out what is in there from the filler hole, and replace with what i think is the most similar to this phantomatic Kamoil!
The steering box is not leaking, but is exuding a bit. It is mid way if i gauge it. Probably not bad for a 60 years old box and seals!
i belive what is currently inside is the Kamoil, it is very thick and smell like transmission oil (see photos).
Thank you for the advice on the tyre pressure!
