OIL type - Cali 1100 Carbed.

This has been asked before, but I wont lie, I am still not convinced either way.

The reason is simple…

I look here, and it says 10/40, I look there and it says 20/50, I look way over there and I hear all kinds of sites saying all kinds of numbers, I have even seen one site saying that they use 5/30 and even 10/60 FFS!

Now, with my 950 Cali years ago, I was using mostly MORRIS 10/40 SEMI
Now, I hear that the Guzzi engine should not use Synthetic and others saying ONLY mineral and others saying dont use Bike oil, just Car Oil, and frankly, I am now thinking that I am no better off and I am more confused than ever before.

Now, I have a can of 10/40 Bike oil that I have been using in my VX800 and Magna v30, but,m I have just gone and bought some Halford 20/50 Classic oil

I definitely want to go 20/50 but would that be wise to do?

Can anyone actual;ly give me an open and honest reply on what oil would be the best to use?

The Cali has only just hit 21000 miles and so its nice low miileage and I have just ( Well, last night! ) taken the sump bottom bit off, cleaned it all up with white spirits, then lots and lots of water to make sure there is no traces of white spirits, then paraffin, then more water, and then left it all dry out overnight, then just now, put a new filter in and washed out the mess pot thingy, and now its back on, but I am concerned at what to put in?

Thanks guys, please release me from my turmoil, and sure, paranoia!

You will not get one single answer, as you have clearly noticed. Opinions are many, varied (and sometimes contradictory) and they will surely be expressed (again) in this thread as everywhere else that you have seen. Read the various oil-related advice already posted in this forum and make your own decision. Some factors you may wish to consider: do you know for sure it’s ok, is it available to you, can you afford it.

Opie Oils do a discount for club members. I believe that they might also offer guidance on suitable oil for a given model.

I will be completely honest, but your reply is EXACTLY what I was kind of expecting.

But yes, person A uses this type of oil and person B uses that and then person C uses the other kind and then person D would not touch this oil but then recommends this that you cannot get anywhere on the planet. It goes on and on.

I already have a few oils… Motad 10/40 SEMI and Morris 10/40 Supersport Synthetic both motorbike oils, and Halfords Classic 20/50 and Castrol GTX 10/40 both car oils.

The Guzzi being a slow engine and a Dry clutch will be fine with Bike or car oil.

As for the 20/50, the reason beind that, is that the engine is a tiny bit ticky ticky, almost tappety sound and thicker oil might help reduce that, but then so will newer oil anyway.

I have recenty herd that fully synthetic is not good for these engines and also 10/40 is better for the shorter runs and 20/50 better for longer runs, and I do intend on doing more longer runs on the Guzzi and keep the Magna for the smaller runs.

Ah, Im still iffy on what to do?

I think that perhaps, what I will do, is write the oil onto a card, and then get the missus to give me the card, and thats the one I will use!

I will simply keep my eyes and easrs open to try listening to how the engine seems??

Surely, there is no way that I can kill the engine is there?

Either its good or if notm, then the engine will sound wrong???

I mean, if people have used these oils, then surely I should be ok??

Again, its all paranoia I admit.

if you’re paranoid, then a tried a tested oil hack is to change it more often.

keep a close eye on how much is being ‘used’, what’s the state of it when it comes out, is it staying in the engine… knowing these things might increase your confidence in what you are doing.

i’ve often heard it said about oil that changing it more frequently “than the book says” is a comparatively cheap way of keeping the engine healthy. what comes out can always be used in the chip fryer, right?

if the bike is new to you, dump the oil at a 1000 miles (or whatever) and see how it looks.

if it helps even remotely, when i got my T3 I read all these oil threads and the whole modern synthetic thing made sense, so I tried it. but - on MY T3 - it wouldn’t stay in the engine. I then tried a Morris 20/50 mineral, the bike was happy, so I was happy. Is mineral better than synthetic in my T3? no idea. but that particular paranoia went away… now, what’s that rattling?

LOL I was only joking about being Paranoid… or was I?

But yeah, I had my 950 and it done 136000 miles and so you would think that I would be ok, but I had an accident a few years back and its made me into a right nob.

Anyway, I have decidied to go with the 20/50. I have put 3 litres in and ran it for a little bit to get the oil through the engine and checked the level and its a tiny tiny bit over smack in the middle of the LO-HI markers, so perfect.
I have not done all the oils and so I hope thats good, and I can relax until tomorrow. LOL.

As for changing the oil, yes, on the 950, I changed it every 5000 miles, and I also changed the filter too. I will admit, that I never once changed or cleaned up the little mesh thingy, but in my defence, I never knew about it and so I never touched it… Given that I myself did 136000 miles before I sold it on, and its still on the road almost 30 years later, I think that I did ok with it. That said, I{ never used it for short runs, I always did long runs on it, and we toured the whole of europe on it ( hence the mileage ).

Anyway, I will keep an eye on it and if I feel that I made a bad choice, then I got other options to go for, but I dont see any problems… Others have used 20/50 in the past so I should be fine!

New to me?
Yes, its done 18K when I got it and now its hit 22K and so thats over 3000 miles in 2 months and so that ok.
I was told the oil had been changed by the previous owner, but given that the shaft had well over half a litre and the gearbox had well under a quarter… I think that they got the two mixed up, and even though the engine was about right, and it didnt look or smell too bad, I left that until I got all the bits I needed, Sump Gasket, Filter etc. So yeah, thats done now.

Mineral v Synthetic.
The only thing that Synthetic might be beneficial for, is that it lasts longer in fast revving engines, and it helps coat the engine better.

For older machines ,or for engines like the Guzzis that are very agricultural, I think that Mineral oil is better.

The 20/50 I have put in today is 20/50 mineral oil… Halfords Classic its called.

Lets see how that fares yeah?

In the past, there was a local car bits shop that was run by a guy, who was getting MORRIS oil, ( Blue and yellow containers ) and he would give me 4 litres for a fiver! - Well good and so I used that and I assume its Mineral oil… I will also be honest, but my first big bike was the 950 California and before that, I was always on MZ Bikes and they are all 2 stroke singles and so I put almost anything into them nd had the attitude that oil was oil. I dont remember if sunflower oil is 10/40 or not LOL ( Yeah, thats a joke )
And anyway, I never knew about Synthetioc or Semi or Mineral for some time, so what the oil was, I simply dont know, but plenty of people are saying that Mineral oil is better for the Guzzi engines and yes, regular oil changes is vital.

I have also heard, that changing the filter is so important… You can change that every 5K and only do the oil every 10K and thats fine. I have been doing that on my Fazer and while I no longer ride that, its on 86K and its running sweet as a nut. I havve given it to my mates son as his first big bike and he loves it so much, he wants to buy it.

Ok, thats enough! - Im already waffling too much as it is.

Oh, hang on, the rattling…

Well, there are 2 noises that are present… one is something in the engine that I dont like. I am trying my hardest to ignore it as my mate says its nothing, and he recons that it could be, and probably is, just the engine still being tight and not fully run-in. Im not so sure about that.

The second noise, I have managed to pin-point, but not solved it.

I was using a phone to record a video of the noise, while I was going around the bike using the camera to go right into each and every nook and crannie as I was going to post it for a mate to have a look.
So, I checked the video on the computer before I posted it and because the camera and my PC audio setup sounded different to my normal hearing, it picked up where the noise was coming from…

I know this sounds silly, but I am deaf in one ear and I cannot hear with the other one, and Im bland in the third one! hehe

Anyway, I dont have good directional hearing and I just hear a noise, but the noise was definitely from the exhausts.

Now, the silencers are NOT stock, they are stubby ones and they have a lovely deep rumble and when pootling along at 60 or so, the sound is beautiful.. Sounds powerful without dominating, unlike the stock pipes, they sound like its a bloody 250cc

Anyway, when I hold the silencer, the rattle stops. I{t only rattles when I rev it, not when its idling.

They have a sort of 2 linked arm thing that holds it on, and this is what causes it to rattle… When I hold iot, and rev it, no rattle. It does this one both sides.

I undone the silencer on the right and shook it, and there is nothing loose thats making any noise, and each bit is in itself solid and so ~I connected it all back and tapped the silencer and there is the sodding rattle again.
So I undone everything again and this time I used some fibre washers to help dampen the vibration, but it didnt help at all??? I went nuts cos I cannot stop the vibration! - I could put the stock silencers back, but as I said, they sound rotten.

So yeah, one sound sorted, or I know what that it, I just dont know what the other sound is?? That one is a tiny tiny sound and again, I only hear it when I drop the throttle nd it drops the revs and thenm its a little whirring sound as the revs drop… Almost like a small fan.

Dont know if its sopm,ething, but this engine has pipes going into the head, under the fuel tank… I cannot for the life opf me remember if the 950 had those?
Im wondering if its somethign like oil cooling system, but could that be a pump that makes that noise? I dont know?

my Moto Guzzi makes a rattling noise” is a whole other thread, and - now - your new life.

I am aware that its my new life, but also its not my first Guzzi.
I am a complete idiot too, I wont deny it.
I have found that one tiny rattle is actually the aaftermarket silencers mounting bracket rattling and even with Fibre washers, I cannot stop the rattle.

But in my head, its about to sieze!

I never used to be like this, but I just am. I hate myself for doing it, but I just cannot help it.
