brubache Posted October 23, 2017 Share Posted October 23, 2017 Morning! I am about to do all the fluids. What is the consensus on drive, gear and motor oil? Synthetic. Weight. Brand. Etc. TY! 1 Link to comment Share on other sites More sharing options...
Scud Posted October 23, 2017 Share Posted October 23, 2017 Consensus on oil? I think we can all agree that it's good to keep oil in all the places it's supposed to be. FWIW, I'm just following the owner's manual specs as closely as possible. I was using RedLine heavy in gearbox and final drive. I may stay with that in the final drives. I remain confused about all the letters and friction modifiers and motorcycle vs car oil - since most motorcycle oils are for engines with wet clutches and that doesn't apply to Moto Guzzi. You didn't ask, but I like using DOT 5.1 hydraulic fluid, which typically has a higher boiling point than DOT 4. 2 Link to comment Share on other sites More sharing options...

vents Posted October 23, 2017 Share Posted October 23, 2017 Oh, boy.. an oil thread. Where's that popcorn emoticon? yeah , they're fine until egos and opinions get involved. How about those who are willing just state what you're using and leave it at that ? I've always used Mobil 1 synthetic in the gearbox and rear drive of my '81 Lemans . In the engine 20w50 Castrol GTX and always changed it before 2k miles . All I can tell you about any of that is that it worked . That bike has 55k miles on it. I haven't decided what I'm going to run in the V11 just yet. 1 Link to comment Share on other sites More sharing options...
czakky Posted October 23, 2017 Share Posted October 23, 2017 Mobil 1 “V-twin” and redline “heavy” or “v-twin” trans. Link to comment Share on other sites More sharing options...
Chuck Posted October 23, 2017 Share Posted October 23, 2017 Ok, I'll play. Currently, Motrex 10-60 syn in the powerplant, and Redline shockproof light in the transmission and rear drive. I ran the Centauro (similar architecture) 42K miles on Mobil 1 V twin and Mobil 1 75W/90 in the transmission and rear drive without issue. Using synthetics, I change once a year or every 6K miles. Filter once a year. If a guy is willing to change more often, I'm sure that any quality SG rated dino oil from around 20-50 would be fine. Why Shockproof light? Many if not most run heavy. Heavy is so tenacious that if you follow a regimen of drain and measure, quite a bit of Heavy will stick to the gears and you will overfill (especially) the rear drive. BTDT. That's my story, and I'm sticking to it.. 1 Link to comment Share on other sites More sharing options...
coreytrevor Posted October 23, 2017 Share Posted October 23, 2017 Red line shockproof heavy in my gearbox. I guess I'm not allowed to say it worked wonders with shift quality, even compared to RL shockproof medium that I was running. Oops! Link to comment Share on other sites More sharing options...
luhbo Posted October 23, 2017 Share Posted October 23, 2017 Castrol 75-W140 Synthetic plus MoS2 for the gears, Liqui Moly 10-W40 MoS2 partly synthetic for the engine. I seldom change the engine oil, just fill up when the light comes on, that's after about 6000 km. I have to add that the V11 seldom sees a run shorter than one hour. I believe in MoS2, not so much in the carrier oil. All my bikes and cars believe the same and don't make any problems. Link to comment Share on other sites More sharing options...
motortouring Posted October 23, 2017 Share Posted October 23, 2017 In the V11 Sport: -Engine Kroon 10w60 - Gears Castrol SAF XJ or later synths (75w140) In the California '82: - Engine 10w40 (10 Euro / 5 liter supercheap). These specs are much better than '82 specs. - Gears also the castrol SAF XJ Link to comment Share on other sites More sharing options...

docc Posted October 23, 2017 Share Posted October 23, 2017 I swore off the RL Heavy long ago from its tendency to "cling" and contribute to overfilling/ possibly contributing to leaks. After seeing those awful images from the inside of one of Scud's gearboxes with the gigantic clots of RL/Heavy: never again. I imagine how much the actual circulating volume is reduced by those gigantic clots of goop. Motor: Redline 20W-50 Group 5 Full Synth/ 5,000 mile changes Gearbox: RL ShockProof "Lightweight" (blue) Rear drive: still leaks 1 Link to comment Share on other sites More sharing options...
vents Posted October 23, 2017 Share Posted October 23, 2017 Rear drive: still leaks what are you using in it ? or did I miss something ? was really curious as to what you are using in that high mileage test unit of yours. thanks Link to comment Share on other sites More sharing options...

I'm currently considering sawdust as an additive . . . Seriously, if you ever look at that image of what Scud found with RL Red/Heavy in the gearbox, it will give you pause putting it in anything. It is not for the squeamish to cast their gaze upon . . . Link to comment Share on other sites More sharing options...

I've been in my tranny a couple of times since I started using it, and the strawberry shake always looks as one would expect. Yeah, it's thick and clingy, but nothing like scuds encounter. I'll continue with it till I see something I don't like. Link to comment Share on other sites More sharing options...
