I have a 1956 Cockshutt 20 deluxe. In the setting up and operating instruction manual specifies to use "Marfak 00" (Texaco) to lubricate the steering gear. I have no idea if its still readily available, but when I googled it I didn't get very far. I am wondering if there is an equivalent product I could sustitute? I reside in Ontario Canada if it matters. Thanking you in advance. Glenn
