Cyril131, Thanks for todays lesson on viscosity
I will use a 10w50 as recommended by RE, I was just curious as to what other folks in the US are using.
I was at the local dealer in Sanford FL (a place where you can ride all year except fo 2 months - July and August, so hot your boot soles will melt to the asphalt at a stop) and they don't even carry a 10w50. Not sure what they would use but I do not care since I will do my own work including the tappets.
Thanks to everyone who responded.

I will be using the cheapest oil that meets the minimum standards. Found 5 litres on eBay for 24.99. Company called 'Westway.'

If you want economical, get behind me.  This stuff is $17.60 a GALLON and it's a 15w50 semi-synthetic.

About 200 miles into my latest oil change on my Classic 500, and so far, so good.

I started a thread about it here:  https://forum.classicmotorworks.com/index.php?topic=28304.0

If you are doing the oil change for the first time, the oil filter can be pretty tightly fitted from the factory, I had to literally crush mine before I was able to remove the old one out. The traditional oil filter removal tool that wraps around the filter wouldn't work well as I didn't have enough room to use that. I had to use VISE-GRIP tool to crush/remove it forcefully. Once you get a good grip, it comes out easily.

So I went and bought a new oil filter removal tool from Auto Zone for $7, and it is awesome, very inexpensive and the right tool for the job.

Attached the picture of the tool in case if anyone is looking for it.

Update: It fits like a glove, and you can use standard 3/8 inch ratchet set.

Thanks for that.
I have a chain oil filter wrench that works with a socket wrench so you can put a 1/2" drive extension into it.
Had it fo over 30 years and the only reason I know it has been over 30 years is because I bought it from the UK with all my other tools when I moved to the US in 1989.
It works great on those "hard to remove" filters.

and then this happened.............

HILARIOUS !!!
(I hope you post this on the other forum)

That is really funny. LMAO

15W is thicker than recommended. While it could be ok with monos that are quite older tech, it will not be ok for the 650. During hot summer periods it should be ok, but in winter it will cause wear and lack of lubrication until hot enough, if it can even reach "hot". This is how people bend conrods.

I live in buffalo and the stealership out here put 15w-50 in for my first oil change. I rode it on that for about 1000 miles, then at the start of this season put in castrol 10w-50 that meets the specifications exactly. I got it on amazon on sale for 40 dollars for 6 quarts, usually its 50 dollars. https://www.amazon.com/gp/product/B008MISF54/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

I'm skeptical of this.  The 10W and 15W ratings are for oils at 0 degrees F.  If you look at the viscosity vs temperature curves of any of these oils, you will see that the viscosity of a 10W oil at 0 degrees F ( -18 C) is MUCH thicker than a 15W oil at freezing (32 F = 0 C) 

You can see representative curves here:  Notice that viscosity is plotted on a LOGARITHYMIC scale.  https://www.engineeringtoolbox.com/iso-vg-grade-d_1206.html

At 212 F. both the 10W50 and the 15W50 have the viscosity of a 50 weight oil.  As they head towards freezing temperatures, the viscosity increases radically.  This temperature dependent change dwarfs the difference between the 10W and 15W. 

This means, for example, that if you have 10W in your machine and I have 15W in mine, and you decide to ride at 28 F degrees,  while where I live it's a balmy 32 F degrees, it's very likely that the oil in my machine is going to be less viscous at start up than your 10W.

If you ride at down to zero F, ( -18 C), you are a braver man than me, and perhaps you'll notice an appreciable difference between the 15W and the 10W, but I doubt it.  I think that the _W ratings can be safely ignored by 99% of motorcycle riders, but the hot viscosity rating is quite important.

On every motorbike forum I have ever been on, there is always this oil question. Be it 2 or 4 stroke, people argue about this all the time. Just put what is recommended. End of.

[Breaker Express]

Rowdyyates, I do agree with you.
My original question was "what 10w-50 oil". I was really looking for a recommendation on the brand as opposed to the viscosity.
It did open a can of worms though.

Except if you ride classic or vintage, often the lubes specified will no longer be made.  It's not easy finding straight weight oil these days, let alone 00 weight grease for your vintage gearbox.

The extra wide viscosity oils didn't exist until recently, with the introduction of full synthetics.

More knowledge gives more options.

Here in the States you can special order pretty much any type of lubricant you need online for pickup, or even with free delivery for orders over $35, right at Wallyworld, and usually for a pretty decent price. That's how I get that Lucas TB-Zinc goop, a couple of ounces of which my old Iron Barrel seems to adore along with its steady diet of regular old automotive Mobil1 15w-50 synthetic for $22 bucks for a 5 quart jug. Not that you "modernos" will need any extra zinc in your fancy-shmancy 650s that the Lucas provides, but my old girl's primitivo flat tappets like a motor oil with those pre-'90s SAE ratings levels of the stuff at about 1,500+ ppm. More modern catalytic converters don't like zinc much, so they've been dialing down the levels of it further and further over the years. But catalytic-shmatalic: I'm riding a rattly old oil lamp.

My point is that you can get pretty much whatever you need: single viscosities, that Motul brand that's otherwise kinda hard to find on the shelves hereabouts, or this perfectly fine Castrol Power1 4T 10W-50 Full Synthetic Motorcycle Oil for $10.64 a quart, which should tick all your 650's boxes what with it being a 10W-50 synthetic meeting the SAE "SL" rating and also that JASO MA2 standard to keep your unit construction engine's clutch happiest. Order 4 and it'll be on your doorstep with free shipping in 2 days: https://www.walmart.com/ip/Castrol-Power1-4T-10W-50-Full-Synthetic-Motorcycle-Oil-1-Quart/292569005

It's a little pricey, sure, but not too bad--about the same per quart as that Mobil1 V-Twin 20W-50 brew that a lot of Harley guys favor.

[twocoolgliders]

For  USA...Lucas also has the correct 10-w 50 motorcycle oil...  I got mine at NAPA auto parts.   I think it took one day come in after ordering.
