Opinion on this oil

[svrob]

Okay so yeah I know here we go...another oil thread. Well I'm about to change the old dirty oil in this 87 kx250 & I don't want to run ATF in it so would this be okay? it's pennzoil 10w-40 non synthetic, here's an aweful picture ?

Well it's not JASO certified, so it 'may' cause your clutch to slip. Give it a try if you dare...

If it is not JASO-MA certified, or known as safe for a wet clutch, don't use it. At a minimum you will need to switch back to a safe oil, worst is you will need to replace your clutch friction ($100, been there).

I don't want to run ATF in it 

 

Usually what we want isn't very practical.

Why exactly would you want to pour in crap that is well known to cause clutch problems (energy-conserving car engine oil) in favor of ATF which has been proven time and again to work perfectly?

If you are dead set against ATF for some reason then use Rotella T. It is cheap, proven over and over, available nearly everywhere, and meets all certifications required. Do a search on TT. The majority of people recommend 1 of three things: ATF, Rotella, or motorcycle specific oil. Everybody has their reasons for picking which 1 they prefer. Nobody has any first hand experience of oil related failures with those three choices.  The same cannot be said for typical car oil. Many examples of people having clutch problems when using them. You might not. Is it really worth saving 4 bucks to use some oil you found laying in the corner of your dads shop? By the way, if you do have problems a new clutch will cost nearly what you paid for the bike if not more.

I don't see the argument against ATF, you *might* be fine with that, I know a lot of jaso-ma qualified oils don't bother to get the certification; if it's so important to you to learn about the oils your considering i would ask chokey. Easily the most knowledgeable about oils on the site

[flattusmaximus78]

Regardless of ATF, only engine oil you should be using is for another dirt bike.

Check out page 8, table 3. It lists the api ratings that can be substituted for jaso rating. Pay attention to the notes on the sm and sn rated oils.

Check the API service rating donut on the back of bottle. Almost all SAE 10W-40 like the Pennzoil shown in the picture are NOT resource/energy conserving so they do not contain additives that will cause your clutch to slip.

Most of the 10/30 oils listed as "high milage" are not ec or rc.
