Engine type:
Performance modifications:
Driving style: (road / off-road / track etc) Moto Guzzi V9 Bobber 2021 850 E5 No modifications Road The Ducati dealer who sold me my near-new v9 overfilled the engine oil, and I have the pleasure of changing it. I'm excited to learn more about it. The fill quantity, to my understanding, changed from 2L to 1.75L with the E5 specification update in 2021, and a confusing array of sources lend the servicer the old 2L number. Any recommendations for all fluids would be great. A specific question: if I were to use Liqui Moly for the trans and bevel box (as they supposedly use the same oil), would there be any issue with using their 75W-140 synthetic hypoid differential oil over their motorcycle specific gear oil?https://www.fcpeuro.com/products/bmw-rear-differential-oil-75w-140-m3-m5-m6-z4-83222282583?utm_source=liquimolysite

It has been said that yak fat will suffice so long as regular changes are done. A multigrade should be better as it will circulate more easily while the engine warms up, and cause less drag. |

Brian, thanks for reminding me that my MG Cali has a dry clutch, therefore no contact with engine oil. So no worries in that respect. So, I'll go for the recommended 20W-50 (Motul if I can find it) even though I do not ride in weather < ~5C or > ~40C. I mentioned that in a comment above, perhaps even a plain SAE40 would be OK for my riding habits. No?!

Paul, thanks for your feedback. Obviously, in my area, I do not ride during the harsh winters, and summer is usually around 30C and rarely over 38C. Plus. no city riding, just highway cruising at 120Km max. Even a plain SAE40 should work for my case but I guess the MG recommended 20W-50 is fine if not a bit overkill. And thanks for clarifying that newer full synthetic oils do not have the compatibility issues of the past. Cheers!

Bear in mind, the only issue with synthetics and plastic bearing gages will only apply to the gearbox. There are no bearings with plastic cages in the engine.

I'd go synthentic as modern ones don't have seal and other compatibility issues that very early synthetics had. BTW your questions only relate to oil viscometrics (look up SAE J300 for the full specs) and I think 10W50 or 10W60 would work fine for your temperatures & engine. Synthetics also generally have better performance specs (API, ACEA, OEMS, JASO etc) & the specs are based on both the range and results of a host of engine bench tests and rig tests (and field testing). Overall though you only need to meet or exceed the original spec of the oil guzzi state for your bike; and since over time specs generally get better and harder; it's harder to buy rubbish ones - especially if you go for a reliable brand.

Hello all, 2001 MG California Special (Bassa) from the NW suburbs of Chicago, USA.
The manual says use Agip 4T SUPER RACING (?!) SAE 20W/50. This is my first oil change, previous owner used same multi-grade viscosity Motul 3000 T instead because the Agip brand is so hard to find on our side of the pond. I've read about some people going to a 10W-60 which is what bikes much newer than mine are using (i.e. 2007 California Vintage). However, I am more inclined to go lower to -say- a 15W or at most a 10W (winter's too cold to ride) and to a 40 or 50 for the higher number, our summers do get around 30-35 C.
Also, I have heard that using full synthetic is not recommended for Guzzi's built up to -say- the mid 1990s, somehow additives attack the plastic casings of bearings" found in these older bikes, so a standard mineral based oil is preferred. My Cali is a bit later built and if the factory recommended Agip is full synthetic, I should be good to go with that as long as it meets the specified requirements and viscosity. What is your feedback about all this? Thank you! |

I don’t think so as they the ATF is only used for the torque converter and not to lubricate the gearbox or clutch plates in a car type auto-box.
I used ATF Dexron II from Smith and Allan, at the last swap, you get 5 litres for around 20 quid. Of course I bow to the cognoscenti on the forum if they have greater knowledge.

V1000 iConvert 1979. Hi, is there any need to shop around for a special ATF oil for the torque converter? I have read all sorts of recommendations including aircraft hydraulic oil. Cheers John.

IMHO It will work no problem but may need changing more often than a full synth/modern additive package.....personally I'd stick with full ester synthetic 10W50 (or 10W60) like Motul for the extra high temperature engine areas protection (pistons/rings/bores mainly).
For Winter grade, although 20W is technically fine for down to -5C ish but it's getting close to treacle; 10W will crank (CCS) & pump (MRV TP-1) much better (faster) on cold mornings.....(I used to do arctic circle engine oil testing down to -40C). |
