10w60 or 10w50
« on: May 24, 2021, 07:44:22 AM »
Sloan's Cycles in TN used Castrol 10w50 when they changed the oil in my Norge even though the manual says to use 10w60. They said MG issued some kind of advisory that said to use Castrol 10w50 now. Bike's running fine, but Jim Hamlin in CT said no, it should be 10w60. He said 10w50 wouldn't hurt it, but it's not right. Was an advisory really issued? If so, is it online somewhere so I could see it?

I've not heard of an update to the type to be used. It would be odd, IMO, for them to change simply because they are now recommending Castrol products.
The V85 recommends Castrol 10w60.

You can get 10w60 from NAPA.It is made in Germany so a local shop might not have it in stock,mine came in the next morning.Cant recall the name.

I don't think Guzzi manuals give you a range just a recommended weight, I also have a Ducati 1098 and in their owner manuals they show you a chart with the range of oils that can be used in various ambients.

As I remember the recommended for the Ducati is a 10W/40 but they tell you all the different grades that are acceptable for an ambient range, going from a straight 10 to straight 40 and a range of multigrades that extend the temperatures the motorcycle can be used in, with 10/40 extending the ambient range most.

I run that bike on a 15/50 as the ambients are well within the acceptable range and the 10/40 makes gearbox action quite noisy when shifting, the 15/50 gives a bettter change and is quieter, not an issue on Guzzis of course.

Unless your running in extremely high ambients and pushing the bike very hard I reckon the 10/50 will be more than good enough. Besides most Guzzi engines tend to run on the cool side, so I don't think it's anything to be concerned about.

I agree with John Henry, if I was in that situation I'd use it until the next change then go to the 10/60.

I pay more attention to oil quality running the bikes on full synthetics

When a shop makes up a story like that, I want to see it in writing. If they can't pull up the actual document from the factory, I assume they are BSing me, yet again, just to unload what they have in stock. I have a low opinion of most shops because of that, which is why I try to do all of my own work.

Thanks for this info. I'll keep it until the next oil change. Kind of disappointed in Sloan's now.

My local OíReilly auto parts story (Midwest chain) keeps this in the back. I had to ask them for it the first time. The guy said they keep it on hand for a couple Porch guys.

My O'Reillys keeps it in stock in the regular oil rack. Oil filters are a different story, I have to get them from the dealer or mail order. No interchange that I could find.

I used to get Castrol 10w-60 at BMW auto dealers, who kept it for an older series of cars.  It was surprisingly cheap.

Now it's hit or miss there.

The 8V 1200s, are Oil Cooled Engines (as all 'Air Cooled' Engines are really).
The Cooling Circuit Oil is pumped straight into the Heads, to flood the areas around the Exhaust Valves, and it gets extremely hot in there.
That's why the -60 Fully Synthetic is specified.
I wouldn't risk -50 in my Engines, under any circumstances.

At the 'other end', I'd never hesitate to use a 20W-60 in Summer.

You can get Mobil 1 in 10W-60, some BMW cars use it, it's reasonably priced, and should be available pretty much everywhere.

Remember we can use car Oils in our Guzzis (Dry Clutches), so you don't have to fork out over-the-odds prices for Bike Oils.

Iím pretty sure the oil you referred to @ NAPA is liqui-moly 10w60 Iíve been getting it there for a few years . I donít recall the exact $$ but oil is cheaper than an engine

I mix 15W-50 and 10W-60 in equal parts to create 12.5w-55. I'll also admit in the winter I add in a jigger or two of 0W-20 and a cap full of Marvel Mystery Oil to help cold starts protection.

I too.  Even in the 2021 V7 (850) engine, the owner's manual specifies API grade G, which has much more ZDDP content than later "modern" grades.

Iíve never fully understood the way the rating works.
For example..
10 W 60
What do the two numbers indicate ?

Best to run a mix of Rotella T and Royal Purple with two teaspoons on molly lube and on full can of "3 in 1" oil ( for cold starts )..
don't use slick 50 until you are fully vested in your 50th year..
NO, It's not pronounced "moder goosy"

I simply cannot find the viscosity rating on this bottle.

I've seen the tech paper from Guzzi at Hamlin's shop. 10-50 has been superseded by 10-60.  Wanna read the manual?  There it is.

To V or not to V, that is the question:
Whether 'tis nobler in the mind to suffer
The slings and arrows of a boring engine,
Or to take arms against a sea of troubles
And by opposing end them....and ride a Guzzi!

10W60 oil is 10W oil with viscosity modifiers added to make it perform as a 60W oil when hot.

Or so I've read.  I'm not a trained tribologist.
