Charlie Smith 192 #1 Posted September 4, 2014 I'm planning on draining and doing a compleat refill on my gearbox for my raider 10. Oil needed is castrol XXL Is there a modern day equivalent? If so what is it? what oils do you guys use? Thanks Share this post Link to post Share on other sites
meadowfield 1,900 #2 Posted September 4, 2014 Charlie, you can use EP80 or EP90. Both are good modern equivalents. I actually use 10W40 in project C4. If it's good enough for a car engine and gearbox then it's good enough for a horse transmission. It just leaks faster Share this post Link to post Share on other sites
Stormin 4,458 #3 Posted September 4, 2014 I use EP90 cos I've got a big drum of it. Share this post Link to post Share on other sites
Triumph66 1,256 #4 Posted September 4, 2014 That's useful to know as I have some EP 90 in my garage left over from my Landrover days. I will use the oil on my Bolens tractor when I drain the gear box oil. Share this post Link to post Share on other sites

Anglo Traction 1,016 #6 Posted September 4, 2014 Yep! Castrol EXP 80-90 API Spec GL-5 for mine. Share this post Link to post Share on other sites
slf-uk 914 #7 Posted September 4, 2014 I believe it is EP80 or EP90 for a WH but the specification for a Bolens is EP90, 2.5QTS if I remember correctly. I am unsure if a WH leaks more than a Land Rover, probably a draw ;-) Iain 1 Triumph66 reacted to this Share this post Link to post Share on other sites
