  Surely, you jest!!   

Surely She does !

Hay , These are not high dollar machines !   

That thought frees me up to think outside the box with my Meteor 350 .

I have found that Mobil One European Formula 5w-40 , returns better fuel millage than 15w-50 motor oils.    Yes , thinner oil circulates better/easier ... who would have thought it might be OK to use it ?   

I do add a touch of Zinc to the mix .       Rotel "T-6 5w-40" might be a good one too it comes with zinc already in it     !

RE --- " HAS " --- to recommend an oil for "ANY-Climate"  from a Desert where it's 115 degrees in the shade   -  to the North Pole .
Well , I don't live in either of those places !   
So
I'm free to use something that is perfect for my environment !   We all are !!        

Be free to think for yourself , get out of the BOX !  It's

Well at least we’ve found an expert on oil viscosity, bearing oil wedges and film strength for the Enfield J series.

And someone who must fully comprehend the design parameters that bound the “box” and be happy giving advice out of it


I’ve bought the popcorn…😜

If RE suggest a 15W-50 oil in extreme low temperatures how is a thinner oil in your less cold environment better?

As you said we are free to use whatever we want but that seems silly to me.

If all running well why change to 7100 ?

I'm just a full-synth junkie.  Esp in hotter engines.  May not bother, we'll see...it gets hot here in summer, so just thinking...or just bored

Thanks for advice and comments. I went ahead and got Mobil 1 20-50w Full Synthetic for V-Twins. Looks like I'm going to need to add another cylinder now to get a twin.

Nah, it'll last twice as long 
FWIW, I used that for 33k miles in my Honda VTR1000 SuperHawk.  Good stuff...

I was sort of thinking that myself .

So putting the wrong oil in your motorcycle makes you a free thinker. It certainly makes you something.

Another thread that's like trying to teach a pig to whistle. 

The owner's manual goes into some detail concerning the appropriate oil. Unless you have some profound insight into why they got it wrong, why second guess them?

 I get it if you have a couple of bikes that spec different oils and are trying to find something you can use in all of them, but otherwise just pour what the OEM recommends into your engine and be done with it. 

[MMRanch]

I've only got 18,000 miles on my Meteor , with most of them being on 5w-40 . 
 
The first time I changed oil I put Motul 5100 15w-50 in it and fuel millage went down .   That tells me the original oil was not 15w-50  , what does it tell you other folks ?

Results are the same whether you stay in your box or not !    It don't bother me either way.   
.........

FFS ... your picture ain't that perty , so your on your own there !       

[MMRanch]

Hay , I'm open to change !

Has anybody tried this stuff ?

Liqui Moly Motorbike 4T SAE 15W-50 Street | 4 L | Motorcycle Synthesis Technology Engine Oil | SKU: 20060

 

Hay there WildCard ,  I ran T-6 in my single cylinder Suzuki LS650 for most of the 80,000 miles I put on it ... before I got tired of 45 mpg .   It was a GAS HOG , but it sure ran strong in the lower RPM's .

The initial 12500km on my Classic 350 J was on RE's own brand oil, Liquid Gun 15w-50.

At 12500km, I shifted to using the Motul 5100 4T 15W-50 (since I wanted to do the servicing myself hereafter and the Motul was easily procurable compared to RE's own liquid gun oil).

After doing around 4500 km on the Motul 5100 4T 15W-50, I have not noticed any mileage drop in my J engine.

What I have noticed with the liquid gun oil is that the liquid gun oil would start getting dark at around 2000km, while the motul still stays much clear even at 4500km compared to the liquid gun.

Just to keep the tone civil I will add, any oil is better than no oil.

Unless anyone knows different?

So would this be the time to discuss oil / gas additives, like Marvel Mystery Oil?  Or would that be bad form?

Haha, yeah, why not? Go for it.
