docc Posted September 14, 2006 Share Posted September 14, 2006 Sometime back it was noted that the Guzzi final drive gear oil that includes the moly is produced by Motul. In a fit of convenience I attempted to order this product from Motul through my local ( not Guzzi) shop. The story I'm getting is that the Motul mineral/moly product is superceded by their "GEAR 300" synthetic. First, has Guzzi superceded its specification for the rear drive? Second, what do they mean by 'mineral' oil? Not petroleum and also not synthetic? KY jelly for the rear drive? Link to comment Share on other sites More sharing options...

However, my Cafe Sport manual specifies a mixture of a Moly additive and conventional Agip petroleum based gear oil. I tried in vain to locate the Agip additive, so I researched the various Moly additives and got a sample from Dow. It's an industrial product sold in bulk, and relatively expensive. I used that in the ratio called for by Guzzi, which coincided with the range recommended by Dow. It is used primarily in hypoid gears where there are high degrees of shear. I have considered using it in the gearbox as well, but do not recommend it for the engine, only because I do not have enough information on using it there. If you are interested, I can look up the Dow spec when I get home later this week. Link to comment Share on other sites More sharing options...
Guest ratchethack Posted September 14, 2006 Share Posted September 14, 2006 GL-5 rated synthetics used in the bevel drive do not require MoS2, or molybdenum disulfide (moly) additives. You can use it, but it's overkill -- it won't hurt, but it won't help either. Mineral means dino (petroleum). Link to comment Share on other sites More sharing options...
richard100t Posted September 14, 2006 Share Posted September 14, 2006 I use the RedLine Heavy shockproof in my rear drive & my transmission. So far so good I dont know about the rear drive but the bike shifts more smoothly now. Now if I could just get an oil that would put the gears a little closer together lol Link to comment Share on other sites More sharing options...
docc Posted September 14, 2006 Author Share Posted September 14, 2006 It would be reassuring that, if Motul doesn't make the moly-dino any longer, the Guzzi factory would supercede the specification to GL-5 synthetic. On the recent "Whiskey Run" ( TN-AL over the Cumberland plateau) a back-of -the-hand check of rear drive temperatures suggested that the synth runs cooler on a 95 degree F day.

dlaing Posted September 14, 2006 Share Posted September 14, 2006 I think there is a difference in performance between standard GL5 synthetic and the same with added moly. Taking a look at It shows that shockproof protects better than the standard redline synthetic. It could be bull, but I believe it. I can't prove that if you added moly to the regular redline synthetic it would perform as well as the redline shockproof, but I suspect it would be similar performance. But I would suspect that adding moly to the shockproof would not improve it Link to comment Share on other sites More sharing options...
luhbo Posted September 14, 2006 Share Posted September 14, 2006 Mineral means Petrol based. That's the name. Oil coming out of stones or minerals. Petrus - he's the rock the church is built on. That's why he's called Petrus. Hubert Link to comment Share on other sites More sharing options...
Greg Field Posted September 14, 2006 Share Posted September 14, 2006 That pink stuff in the shockproof heavy ain't ground up strawberries; it's moly, boys. Moly is good for guzzi gears. Link to comment Share on other sites More sharing options...

Guest ratchethack Posted September 15, 2006 Share Posted September 15, 2006 FWIW, I did a lot of reading on Redline Shockproof before I started using it in the Guzzi. At that time, I don't think anyone on this Forum was using it. I'd been using their MTL gear lube in 2 car transmissions for decades and had become thoroughly convinced of its superior performance and durability. I called Redline HQ in Benicia, CA, and spoke with a Tech. I asked a few questions, including the correct application for the Guzzi. RL Shockproof Heavy is the recommendation for both trans and bevel drive. It's a GL-5 rated synthetic, and contains extreme pressure (EP) sulphur-phosphorous solid particle dispersion compounds. It neither contains, nor needs moly. Link to comment Share on other sites More sharing options...

It looks like graphite. Link to comment Share on other sites More sharing options...

Ryland3210 Posted September 15, 2006 Share Posted September 15, 2006 Redline'll tell you it's a synthetic moly. That would be enough to drop Redline's credibility to near zero, unless they have invented cold fusion, or are making the element with their in-house particle accelerator and then "burning" it with Sulphur in an otherwise inert atmosphere.
