Is Golden Spectro a good oil to use in the Z? Is there a better oil to run? If so what weight? I live in Virginia and the coldest we get is about 10 degrees. The hottest we could ever get is 100 degrees. Should I run 10w40 in the winter and switch to 10w50 in the summer or just run 10w50?

i would just run 10 40 all year round were you live

 

Not sure about the Z but my 84 GPZ750 loved it.

 

Where can I get it on the Internet? Rocky Mountain Atv is sold out and Dennis Kirk doesn't sell it.

Try staright from Golden Spectro.
