Can anyone in the UK (or outwith) tell me what they use for motor oil, gearbox oil or diff oil. I'm ordering the filter and plugstoday so I would just like your thoughts on which type would be best.

Also wheres this - Emptying the oil drain hose from filter box end???

Any help would be great

Cheers

Engine Oil
Follow the specs and go for the best synthetics you can get hold of seems to be the consensus. From reading many threads what brand you use is down to preference and what’s available. I’ve been able to get hold of Castrol and Millers 10W60 reasonably easily
See Pete Roper’s advice and warnings on mineral oils in the 8v engine, from a guy who works on these things professionally - https://www.guzzitech.com/forum/196/4049.html

Oil drain hose
This will be the pipe that runs from the rear of the airbox and ends with a plug in the lower shock linkage/swingarm area

Gearbox/CARC
For my Breva 1100 its 85W90 for the gearbox and 80W90 for the CARC on the spec sheet – I went for a synthetic spec that covered both (Millers CRX 75W90) – you can change both from a single litre bottle. Up to you whether your happy to go this way or prefer to put the different specs in the CARC and gearbox. Check out the threads on under/overfilling.
In the UK I found it easy to order quantities for a service on EBAY if you’re not close to a retailer..

On my 02 Cali EV I run
Castrol 20w-50 petroleum base in the Engine
My 08 Norge I am running Mobile 20w-50 full syn. Sg rated oil
In the transmission and the final drive I run Redline heavy Duty Shock proof in both of them
the Norge has 1100 miles
the Cali 34,XXX
 
For my Stelio I run

Castrol Edge Sport 10W-60 - an SAE 10W-60, API SM/CF, ACEA A3/B3/B4 full synthetic engine oil - this a Car oil not a motorcycle one. Moto Guzzi's don't need all the extra additives and stuff put in motorcyle oils for the gears and clutch.

For the Gear Box and Carc - I run

Castro Syntrax 75W/90 - A full synthetic, wide viscosity span, automotive gear oil

I ran this combination in my old Le Mans Mk 5 from new, with exceptional results - still had hone marks in the bores at 150,000Ks and never any problems from the gearbox/final drive.

For my V7 Clasisc
The same Castrol Edge Sport 10W-60 in the engine
The same Castrol Syntrax 75W/90 in the Gearbox
And in the final drive box - Castrol EPX 85W140 extreme pressure hypoid gear lubricant (although this can be a bid difficult to locate in smaller quantities here in NZ)

I use to run OEM Agip oils.

Currently I’m changing my 1200 Sport to Penright Sin10W-70 for the engine and Sin75W-90 for the rest. I tend to prefer synthetic, some don’t. On my partners 750 Breva I’m running bazaar mix of Agip Racing 4t in the engine, Penright HYPOID 80W-90 in the gearbox and Agip Gear MG 85W-140 in the transmission.

Nothing real definite to add I’m afraid. If it helps I don’t think anyone has identified a “bad” oil out there that Guzzi’s don’t like. Although I remember from Guzzitech advice to make sure you used a 140 in the rear drive on the small blocks.
 
Thanks for all the advice gents, I'm getting the bike serviced on Thursday at my college as theirs no dealer in the West Coast of Scotland. I've know the Bike Mech lecturer for the last five years and when I mentioned that I'd got a breva he almost bit my hand off to service it. He called it a 'proper engine!' and wanted to show the students how to adjust 'real' valves. Who am I to pass up a free bike mech!!!! :D
