nwtdiesel Posted September 2, 2014 Share Posted September 2, 2014 Lets get this started Mendeola recommends 80w 140 gear oil but I see some guys running other weights and brands. What do you guys run? Why do you run the fluid you do and how often do you change it? Some of the most common oils I see used are: LAT Lubeatech 85w 140 Synergyn-Syngear II 85-140 Mobile One Full Synthetic 75w 140 Red Line Shock Proof Synthetic Kendall SHP Synthetic Gear Lube 75W90 Royal Purple 85-140 Swepco 212 Lucas 85w 140 What local Vegas shops carry these top brands?

dunefreak Posted September 2, 2014 Share Posted September 2, 2014 Swepco 212. I change it once a season. I believe Butch's and NV Offroad Buggy still carry it. Quote Link to comment Share on other sites More sharing options...
ynot Posted September 2, 2014 Share Posted September 2, 2014 Yep that is what I use also. Butch's prices are a few bucks cheaper than Nv. off road. Quote Link to comment Share on other sites More sharing options...

nwtdiesel Posted September 3, 2014 Author Share Posted September 3, 2014 (edited) Well crap. I picked up two gallons of Swepco 212 today. Butches had it for $80 a gallon. The Moly is for better protection on the gears and main bearing I believe. Not so much the shifting.

FireKracker Posted September 3, 2014 Share Posted September 3, 2014 I have a DECO case in my car purchased from john at RC Trans ..... He recommended that I run Lubrication Engineers inc "Alien Blood".... I got nothing to add to his recommendation other than his reputation. And it is pricey like $80 a gallon.

ltr450rider Posted September 3, 2014 Share Posted September 3, 2014 @@nwtdiesel, Run it! its not generally going to hurt anything, if your shifting becomes stiff or notchy, where you have to push hard on the shifter and it doesn't want to go into gear easily, I would pull it. That is the complaint that I hear every so often on my end, we have had people change to oil without moly in it and it tends to fix the issue. Moly oil is generally designed for rear end gears that have a lot of offset between the pinion and ring gear where there is a lot of sliding action between the teeth. Synchromesh type shifting systems rely on friction, so the moly tends to be too slippery and the synchros have a hard time grabbing the gear which makes for stiff shifting. The extreme pressure additives which designates the difference between API GL-1 through GL-6 designated oils is what protects the face of the gear teeth. We only ever see GL-4 and GL-5 gear oils today, Most 140 weight oils carry the GL-5 designation. A few years ago, it was thought that moly was great for everything, and it does work great in sequentials. If you are running it in your synchromesh trans and it works, keep running it, there is nothing wrong with it. Quote Link to comment Share on other sites More sharing options...
nwtdiesel Posted September 3, 2014 Author Share Posted September 3, 2014 Yea i'm going to run the 212 for sure. Quote Link to comment Share on other sites More sharing options...
nwtdiesel Posted September 4, 2014 Author Share Posted September 4, 2014 Today I raised the front of my car a few feet off the ground and drained the trans fluid out. I let it drain for a couple hours and ran a quart of 212 through it to help get the old fluid out. After pouring a gallon of fresh fluid in the trans I looked into the Swepco 212 jug and it had a ton of Moly still in the bottom of the jug. I poured a little oil back in the jug and shook it all around then dumped it into the trans. I did this a few times and the Moly just kept on coming out. For anyone who uses Swepco 212 I recommend dumping half a gallon in the trans then shaking the rest up real good to get the Moly out. 1 Quote Link to comment Share on other sites More sharing options...
