Not another oil thread but I need some guidance

[rx7171]

I use Mobil V-Twin 20-50
Has Zinc needed for flat lifter engines and claims best for higher tempertures of air cooled engines.

Mike,
As has been stated here many times, just make sure the oil you choose has added zinc. Over the last few years I've seen many cam lobe failures, particularly on Triumph/BSA triple motors (mine included). Ok some had substantial mileages but some didn't and I reckon most of the failures are down to using incorrectly spec'd oil.
A couple of years ago I started to use Australian Penrite 20w/60 classic light and have been very happy with the results, ie oil doesn't seem to get as dirty and retains good pressure even when very hot.
The only problem with it is availability, I have to order it off the internet at 4 x 5 litre cans a time.

As Sam says, Zinc is vital in these old engines.

Look for an oil that is made from high quality base stock, and has a good additive package that includes high levels of zinc.

I use Redline 20/60 motorcycle oil, they have industry leading levels of zinc etc (their motorcycle oils have more zinc than car oils) and am very happy with it. I order it online a few bottle at a time, so I always have some 'in stock' and run all my old bikes on it, this makes life quite simple.

These days, with rapid delivery services and on line ordering ability, limiting yourself to what is available at your local store is unnecessary IMHO.

LoL is he still at it then. On advice from LAB, I used the friend/foe tool in the control panel. It's not perfect, but adding the usual suspects to this significantly reduced the amount of non-informative c@/p and infantile humour that you have to sift through, which has crept in over the past few months.

Norton's last recommendation for the Commando was a mutlti-grade detergent 20-50W.

Norton's last recommendation was to use monograde oil in preference to multigrade.

Norton Service Release N3/59
Recommended Engine Lubricants

All Commando

Worldwide (General Distribution)

Important amendments to all previously issued engine lubricant recommendations have now been confirmed by the Norton Development Department (see also Service Release N3/47 May '73).

H.D. SAE40 Mono-grade oils meeting A.P.I. service SE or SD performance level now form the preferred engine lubricant recommendations for both current and previous 750/850 models.

(SAE 30 equivalents for ambients below 32°F. (0°C.)

(SAE 50 equivalents for ambients above 90°F. (32°C.)

The previously recommended Multi-Grade lubricants continue with full approval for use, but it must be noted that all future recommendation charts in Rider and Workshop Manuals, and other Service publications will indicate H.D. 40 Mono-grade oils (A.P.I. SD or SE service rating) as the prime engine lubricant recommendations.

 

[X-file]

High detergent oils are most likely to cause a problem when the rings are bedding in. You can end up with glazed cylinder bores if you don't thrash the engine enough, and baby it. Then you're stuck with high oil consumption.

The Norton. Service Notes, again, the old chestnut written when NVT were on their uppers and probably got a boat load of old crap oil, for two balloons and a whistle !

Les you can't keep bringing this up, not after all the other information that has turned out to be misinformed . I mean these are the same guys that came up with so many other bright ideas.

The Service Release was issued in July 1973 when NVT had only just come into existence and was far from "on its uppers" at that time, it was only subsequent events that led to the eventual demise of NVT two years later.
As for having "a boat load of crap oil" (which I seriously doubt as they had been recommending multigrade for some while prior to that), what on earth has that got to do with subsequent oil changes as I don't remember ever seeing cans of "Norton brand" oil?

Les you can't keep bringing this up, not after all the other information that has turned out to be misinformed. I mean these are the same guys that came up with so many other bright ideas.

A statement had been made that Norton's last recommendation was for 20w-50 multigrade and the service release simply shows this was not the case.
Agreed, things have moved on since then, and monograde oil may or may not be the best option to use now, however it is interesting to note that whether outdated or otherwise, Andover Norton and some others still recommend monograde.

Jim C. recommends 20W50 V-Twin. Good heat curve and additives for the cams. That's what I went to from SAE50 VR-1 after break in. Sure pushes over easier now. Leaks more too.

Thank for that les

Was that a 357 magnum you just let go into your foot , the 1973 oil crisis changed a lot of things in this country!

No, not at all, and I also don't see what the fuel crisis has to do with oil grade recommendations either?.

And yes, I'm still using monograde engine oil in my Commando.

 

[Biscuit]

My, my, we do love our oil..."I will not be happy until you use the oil I do"! Hey Mike got any questions about tires? :roll:

On that les I will bow to your superior knowledge , no wonder GB lost her empire!

Glasgow had the worlds first X-RAY unit in a hospital . Down south they had them in fairgrounds to look through women's clothing. Speaks volumes.

J,
a post from you that is not sarcastic or condescending would be nice - even if only once in a while.

And they're probably still using it? :roll: Oh dear, it seems were are drifting off topic once again :?

The use of X-rays for medical purposes (which developed into the field of radiation therapy) was pioneered by Major John Hall-Edwards in Birmingham, England.
