Newbie100 0 #1 Posted May 26, 2016 Could someone give me a definite answer as to what oil or gear lube that gear box on my 36 inch tiller needs and how much? I have gotten a lot of conflicting answers.. thanks in advance Share this post Link to post Share on other sites
daveoman1966 3,841 #2 Posted May 26, 2016 I use 140W . Some use 90w, but 140 is thicker and less likely to seep thru seals and leak. There are no hi-speed gears in the box so 140w otter be fine. 2 Share this post Link to post Share on other sites
Newbie100 0 #3 Posted May 26, 2016 Would 85-140w be good? And how much do you happe to know? Share this post Link to post Share on other sites

Newbie100 0 #6 Posted May 26, 2016 Thank you all for your help. Looks like one quart of 90-140w my 85-140w should work perfect. Couldn't find 90-140. Share this post Link to post Share on other sites
