Original specs call for GL4 (90 weight) in transmission/overdrive & diff. The only gear oil I can find in Ontario is GL5. From what I've been able to determine through some web searching is:
1. GL5 is not the same as GL4 (extra EP additives in GL5 are hard on yellow metals in transmission - not sure if diff has any yellow metals).
2. OD does not like synthetic gear oil.
3. Motor oil (as alternative to gear oil) does not provide EP protection (gear oil does).
Does any one have any recommendations/suggestions on where I can source GL4 gear oil (preferably in Ontario)?
Do the results of my web search represent the common consensus among TR6 owners?
