Title: "SN" 10W30 Full-Synth ok?
Post by Fujisawa Rob on 04/03/11 at 16:36:57

The owner's manual states SF/SG 10W40. Is SN ok? I've read that certain additive packages can be less than ideal for motorcycle transmissions.

SN is low ZDDP oil, stay away.
Go with a JASO MA rated oil like Rotella T6

I think I want 10W40 for an air-cooled bike? Especially in Florida.

check out the owners manual, it says thicker with more heat.
But in my tests, 40w kept the head cooler.

Full-Synth motorcycle oil seems to work the best in motorcycles.Klotz being the one of favor here.

I hope we're not haggling over 10-40 verses 15-40 ?
In sub zero, I mite prefer the 10. In Florida I'd prefer 15

I'll look for 15W40 Rotella.

Just go to Walmart and buy the regular 10w-40 the manual recommends. Oils are much better than they were 30 years ago. Don't sweat it. The engine won't last more than 70k anyway, so don't waste your money on expensive oils...

My odometer says 14k, but I find that very hard to believe for an '86! Although, the rubber (cable boots, etc.) is in good shape. The paint is faded though. I dunno, 14k seems unlikely.

Major thing to remember is to HAVE SOME OIL in there ....

+1 on Rotella, it has all the good stuff we need and lacks the bad stuff that kills our clutches and if you buy it by the gallon (white jug is dino, blue jug is synthetic) you know you have an oil that has been well tested by us here on the list (and has become our favorite oil due to low cost and best benefits of any oil tested).

But in the end, remember rule #1,  HAVE SOME OIL in there ....

More engines die from lack of rule #1 than for any other reason.

And especially for any oil burners, to that I will add,........
If you use the side stand method of checking oil, and keep the oil near the low line, you will be carrying nearly a 1/2 qt more oil in reserve.

Big singles with over 15,000 miles do tend to sip a bit and have to be topped up bi-monthly (or in Verslagen's case mebbe bi-weekly).

What Routy is referring to is the side stand oil check method which is used more by our older members whose bikes all do tend sip a little bit.

If your bike is newer and uses no oil, you don't have to worry about researching it yet as you really don't NEED the side stand method yet.


;D




Ya see, ya gotta flick the plastic worm out into the water and jest reel it back in real slowly, letting it bump enticingly off the bottom using little subtle tip jerks to give the wiggly plastic tail a realistic flipping motion ....

Versy says if he puts in over how much oil that supposed to me in it goes out fast.So why would you over fill it.

Oops, I done woke Bill's fingers up before he had his first cup of coffee -- my bad.

Bill is trying to say if your bike doesn't regularly use any oil you don't need to consider the side stand method yet.  

But he was trying to personalize it some jest to take some of the sting off the last oil comparison done on his favorite oil during the big oil war right before the last little one, during which time it was found his favorite synthetic really didn't offer any advantage over several other cheaper synthetics it was tested against.

Same data actually made most of the rest of us into oil agnostics -- pick a brand you like then KEEP SOME IN THERE.  

Paying $13.99 a quart does seem sorta steep for same-same performance against $4.99 a quart synthetic oils (and with regular oil changes the $2.99 a quart dino oils begin to look very reasonable too since on a standard bike syn oils are not really needed).

What rpm do diesel motors  turn going down the road at 60 mph.

Title: Re: "SN" 10W30 Full-Synth ok?
Post by Oldfeller on 04/07/11 at 06:49:16

Dunno, can't say that I have a diesel personally.

My XV535 turns up to 9,500 rpm before the tach hits the little red line and my recammed Savage regularly goes over 7,000 rpm so yes I do invest in that little extra protection that is offered by synthetic oils as I deem it prudent.  
I think I need it ....

Standard Savage engines never really see 5,000 rpm as the stock cam flat lines you about then and the highest temperatures we saw on Verslagen's test data shows that standard dino oils such as white jug Rotella would be good enough for normal Savage interstate temperatures and rpms.   Hey, as a matter of fact stock Savage engines do run in the same rpm range as open road diesel engines -- ain't that a hoot.

However, the diesel engines are much more stressful engines than gasoline engines anyway, the Savage engine runs a compression ratio of 10:1 while diesel engines start with compressions of 20:1 and go up as high as 25:1 in some versions.  The bearing loads in a diesel engine are quite extreme compared to anything gasoline driven.  

Top fuel engines are closer in oil performance demands to diesel engines than our Savages are, so you are buying an oil that is performance overkill for the Savage when you plunk down $2.99 a quart at Walmart for that big white gallon jug of Rotella T .....

$2.99 a quart with known good for a Savage performance -- JASO MA rated and approved for motorcycle use.


;D


Ahhhhh ....

Earl, can you hear me buddy?

I use the side stand method for only one reason, saftey ! I dropped my bike while checkin the oil, and that ain't never gonna happen again.
And while using the side stand method, I gain the advantage of the more oil, and all the advantages that  goes along w/ more oil capacity.

I didn't know anyone had experienced more oil consumption or any other disadvantages from running the more oil. I sure haven't, and my bike at 6K mi has run the more oil by the previous owner since new.

I'm not telling any one to use the side stand method, but it is an option, if you feel safer checking the oil that way, or if you like running more oil. For myself I like both.

Over the road diesal trucks only turn an average of 1800-2500 rpms @ 70mph with a 13liter motor hauling an average of 39 tons or 78000 lbs. When I owned my truck all I ever put in it was rotella and now all my bike gets is rotella

I know diesel oil is made for slow rpm engines not the rpm that motorcycles turn.
