  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

What Is The Propper Oil Weight I Should Be Running

I hate to have to ask any question about oil but here it goes. I am trying to find the correct oil weight I should be running in my 2011 TXC 449. The manual says 10w-40, but I have seen some threads were posters stated that the weight of oil is a little lite for that engine. So is that true and if so what is a more appropriate weight?
After I read their comments and comparing oil weight to temperature ranges from my wife’s KLX 110L owner’s manual I have figured that I should probably use 20W-50 in the summer and 10W-40 in the winter. I live in western Pennsylvania were the summers reach the 90’s (F) and I will ride then and in the winter I will not ride in much bellow freezing (32 F). I have thought about mixing the two weights to get a 15W-45 if mixing them in equal parts yields this weight. Just for some reference I have in the bike now 10W-40 Amsoil Motorcycle Syn and I would use 20W-50 Amsoil Motorcycle Syn or mix the 2 oils.

Thanks,
Jake
 
I'm in PA too Jake and also use Amsoil 10w/40 in my TE449. Think I'll be sticking with it unless there's a real good reason to switch to 20w/50. That's what the factory manual recommends and the bike's working great so sticking with what works.

I'm pretty sure that the two oils would seperate, like salad dressing.

??? You're probably kidding, but I hate for someone to read it and believe it.

Salad dressing is oil and vinegar. Different viscosity motor oils won't separate. I've mixed oils for decades with no problems. Suspension guys mix different viscosities all the time to get the exact thickness they want.
 
I did some research after reading your post, ur right, u can mix viscosities. I did not know that. My thought was the different thicknesses would separate, however because the oil has the same molecular base they will blend. I also read that it is advised that u only mix the same brand, and type. Ive never mixed oils, just used what the factory recommends. Good learning. I also live in w pa, and I'll run the 10w-40 that it says in the manual. OHR, any thoughts as why to run the 20w-50.

Higher viscosity oils are used for hotter conditions, lower viscosity for colder. In low temperatures (Canadian winter, for example) you want a lower viscosity oil for cold cranking and more effective lubrication during startup.

This article sums up the viscosity ratings pretty well: http://www.zddplus.com/TechBrief13 - Oil Viscosity.pdf
 
Thanks fellows i appreciated your input and wright184 thanks for the link to the article. I just wish there was a little more oil information in the manual and I don't want ruin the engine or shorten its life because I used the wrong oil weight ($$$$$). I am glad the post did not turn out to be a typical oil post with all kinds of bashing and rants.
 
Damn, I was just about to start bashing and ranting!
It's amazing how crazy people get about motor oil. It's as bad as politics and religion...
