  • Synthetic Oil or not

    I'm due to change the oil on my ZZR now ive read via a few "other" Forums that using Fully Synthetic May cause problems with the clutch, is there any proof to this? I would prefer to change the oil to the Fully synthetic stuff, or semi synthetic. Ive noticed guys on here talking about fully synthetic being used without problems.


    Synthetic Yes or No?

    Re: Synthetic Oil or not

    I've been running full synth in my Connie for 40,000 miles and haven't had a problem yet. Lucas to be specific.
    I'm pretty hard on clutches too. Stocker is holding up well.
    KN, this ride's for You.

      Re: Synthetic Oil or not

      I have been running Motul semi-synthetic 10-40 for years now. I put over 50,000 miles on my ZZR with no problems whatsoever. I have since put over 50,000 trouble free miles on my ZX14 using the same product. I should also note that neither bike ever used a drop of oil or had clutch problems during the entire time I owned them.

        Re: Synthetic Oil or not

        Using ANY oil with "friction modifiers" will cause problems with a wet clutch. Synth or Dino oil.
        Beware an oil labeled "improves fuel economy" or "extends engine life".

        Be sure to read the labels on whatever oil you choose.

        The ZZR spec is :
        Grades: API SE, SF or SG or....
        API SH or SJ with JASO MA
        Viscosity SAE 10W40

        Lots of folks here use Rotella-T6 (T6 is the full synth version) which is a 5W-40, JASO-MA. It's a diesel engine oil, so it isn't labeled with "S" classes (actually it shows "SM"), but API class CJ-4 is spec'd for high-speed 4-stroke engines with EGR (exhaust gas recirculation). Somebody will be along shortly to explain it better, but, I've been using T6 for 6 years with no problems.

        The API specifications for the Zed are outdated. I'm not sure you'll find too many oils marked SE, SF, SG or SH... SJ is still current production.

          Mobil 1 15-50. 60K on 2 bikes no problem. I used T6 couple times too. Seems to shift smoother with Mobil1 to me.

            I would use the Racing 4T version... Not sure about the non-racing version.
            Non racing is SJ, but not specifically JASO-MA.
            Racing version is JASO-MA.

              In the unlikely event that it does start to slip, you can fix it by changing back to dino oil.

              The Zed shift quality is so much better with a full synthetic.

                I'm running the Mobil 1 Racing 4T Syn 10w40 with a K&N Oil Filter in my Zed and all is good. Shifts are nice & smooth and she definetly idles & run much quieter than it did prior to the oil change.

                  Yep, Mobil 1-4T here as well. Ran Rotella T for a bit, but have connections on the Mobil stuff now. 12 years and still going.

                    Personally I have been a big fan of Amsoil which from what I know is the first open market synthetic motor oil. Does anyone here know anything that I should know that may not be so good about Amsoil? Thanks

                      Just the cost.

                      Wally usually has the M1 and T6 for a manageable price.
                      For me Amsoil has always bee higher priced. Otherwise amsoil should be fine.

                          The main reason I use a full synthetic is because the gear changes are so much smoother and I hardly ever miss shifts.

                            I'm inclined to try Castrol 4T 10w-40 at $7.18 / qt compared to Mobil 1 at $11.80 / qt. (amazon 6pk pricing w / free shipping. Don't know where to get it any cheaper)

                              There's a reason the Mobil is more expensive - they use better base stock. It's $99 for a 4 litre pack here!!! Needless to say, I use something cheaper...
