Supreme 7000 Synthetic Plus Racing Oil SAE 20W-50

No eBay APP ID and/or Cert ID defined in Kunena configurationSchaeffer's motor oil.what you think?

I searched using Google and couldn't find anything bad about it in the first 4 pages.
Other than that I know nothing about it.

overkill?

DON'T DO IT!

I would never put that in my bike. It contains molybdenum (moly) which is known to be destructive to wet clutch disks (which is what the KZ has). Our bikes require JASO-MA certified oil. The eBay guy is providing bogus info (shocking, I know) trying to make a buck. UPDATE: Thanks to martin_csr the seller corrected his bogus information.

Even the Schaeffer Oil website says:

"7000™ Synthetic Plus Racing Oil SAE 20W-50 (#705) is not recommended for use in those motorcycle and ATV applications that specify engine oil that meets JASO MA or MB. Use of #705 in applications that specify JASO MA or MB oil can cause slippage and improper engagement of the clutch mechanisms. It's is also not recommended for use in 4-cycle marine engines that specify the use of a NMMA FC or FC-W 4-cycle engine oil."

Disregard what the eBay seller says! See the Schaeffer website. Ed

Shell Rotella. Available at Walmart (and other places) for a reasonable price. www.shell.com/rotella/products/t6.html

If you want full synthetic I recommend Mobil-1 Racing 4T MOTORCYCLE oil (see link). It is JASO MA approved and works well; I've been using it for the past 7 years. I buy it at Pep Boys. DO NOT use Mobil-1 car oil in the bike. Ed

Don't use this oil. Your wet clutch will slip and eventually burn up.

Use Shell Rotella 15W - 40 straight oil.

If you want to protect you Kaw engine, purchase some PTFE oil additive and add to oil per instructions. Don't just dump it all in. To much is a bad thing here.

Shell Rotella T6 is MA certified for use in wet clutch applications and costs about 50% less money than "motorcycle oil". Diesel oil is a great choice for motorcycles because it has extra zinc and phosphorus, which are critical high pressure anti wear additives. Most diesel engine oils are not MA certified, but that doesn't mean they are bad for your bike, rather the manufacturers haven't bothered to go through the certification process. Another excellent oil for bikes that is not MA certified is Mobil 1 15W-50. The blend for this particular oil has extra zinc and phosphorus and lots of motorcycle folk use it (although it's quite expensive).

For those interested in learning more about oil, including lots of info about oil analysis, pop on over to Bob is the Oil Guy. Great forum... www.bobistheoilguy.com/forums/ubbthreads...nalysis_-_Motorcycle

After sending him the info provided by 650ed, the seller has now corrected the item description.

I'm not going to name drop, But if not the top NHRA motorcycle engine builder he is 2nd.

He only recommends using Rotella non sync in his engines.

I heard it come out of his mouth, and he went on for 4 mins about why. Was pretty cool to listen to him, but he kinda lost me after a min and a half......... :blink:

Most of us on here already know how good this oil is.

Think about it?

The PTFE thing has a bad rep from test data I saw. It is basically the powder form of "Teflon" added to the oil assuming that since it makes a frying pan slick, it will work as a friction reducer in an engine. The problem is it has no way to bond to surfaces if it is just floating loose and accumulates places it does no good. I think it is useless at best and one test report said it can clog up narrow passages.

YMMV

The basic ingredient is the same in most of these additives: 50 weight engine oil with standard additives. The magic ingredient in Slick 50, Liquid Ring, Matrix, QM1 and T-Plus from K-Mart is Polytetrafluoroethylene. Don't try to pronounce it: call it PTFE. But don't call it Teflon, which is what it is, because that is a registered trademark. Dupont, who invented Teflon, claims that "Teflon is not useful as an ingredient in oil additives or oils used for internal combustion engines." But what do they know? They haven't seen the secret studies done by Petrolon (Slick 50).

PTFE is a solid which is added to engine oil and coats the moving parts of the engine.

However, such solids seem even more inclined to coat non-moving parts, like oil passages and filters. After all, if it can build up under the pressures and friction exerted on a cylinder wall, then it stands to reason it should build up even better in places with low pressures and virtually no friction.

This conclusion seems to be borne out by tests on oil additives containing PTFE conducted by the NASA Lewis Research Center, which said in their report, "In the types of bearing surface contact we have looked at, we have seen no benefit. In some cases we have seen detrimental effect. The solids in the oil tend to accumulate at inlets and act as a dam, which simply blocks the oil from entering. Instead of helping, it is actually depriving parts of lubricant" (Rau).
