Well don’t know about prime but a gallon is 38.99 which is 49 Canadian one choice for shipping is 49.00 most likely us so that is about 62 Canadian so 111 dollars and who knows if customs will want a few bucks I am going to wait a bit .Was reading and watched a few videos on u tube about the oils and it looks like a gl5 oil will be okay appears the additives attack the yellow metals when overheated and not during normal use ,the one video a fellow had a brass ring in a jar of gl4 and a ring in gl5 oil for a year and the gl5 ring looked shinny but did not decompose the ring another video of a rebuilder who has not seen a gl5 oil dammage a transmission only lack of oil or heat ect . It would be nice to have theses oil manufactures provide on label that there oil is good for brass ect. Also if anyone has had any bad results with the oil they used in these older manuel truck transmissions speak out please.
