    I found that a local NAPA store was stocking german made "Lubro Moly" oils.....for the Bimmer and Audi / VW crowd. Fully Synthetic GL5 rated gear oil with Moly in it at a price less than Amsoil, royal purple or Readline.....it is made for the quatro diffs and gearboxes. I think it can handle a guzzi....first impression is:

    who put a Jap gearbox in my Guzzi.....I am off to mid-ohio (1500 miles) so I will see how she goes......

    I think it should be no problem. Go go go!

    I have read in other Guzzi websites that some Guzzi gearboxes are fitted with plastic retainers for the ball bearings and that synthetic oil softens these, causing the bearings to fail. Maybe untrue, but the writers claimed to have wrecked gearboxes because of this. Any comments from users of synthetic oils in gearboxes and rear drives? I'd love to use it, but not if it presents a risk.

    I would love to know how a synthetic oil would soften plastic or rubber.

    Actually I use synthetic with no problem. I also have stopped using Moly in the rear drive. I have seen the sulfur portion of the moly form acids that will pit the bearing races. I had a bearing fail from this pitting. I won't ever use Moly again. Besides, no one else recommends moly for their rear drives. Moly, good for gears, bad for bearings.

    I think you'll find that moly is no longer called for by the factory, at least for the smallblocks.

    Regardless of the dreary and interminable engine oil arguments there is absolutely no doubt in my mind that the modern fully synthetic gear oils are a fine and splendid thing. I have seen no need to add moly to either the gearbox or CARC on any either of my 'Newer' Guzzis and if I were to get a pinion failure I'd be far more likely to sheet it home to the crappy fueling at low RPM beating the snot out of the driveline, (Especially on the 8V without a face cam shock absorber in the gearbox.) than any failure of the lubricant.

    I've been using Redline Heavy Shockproof in the rear drive for a year now with no ill effects.


    So far.

    I run Redline Heavy ShockProof in both the gearbox and rear drive, and Mobil 1 V-Twin in the engine.
