    What type/brand of engine oil do you guys find the best for our zl900's? Some where I read synthetic wasn't good for our engines. I'm doing my first oil change on it and want to use the right stuff. Thanks.

    The ZL900 and ZL1K's use a different starter clutch, the 1K being the better setup. Some people have had issues with the starter clutch acting up on their 900's after using synthetic. Most are happy with MC specific oil or something like Shell Rotella. Just don't use any type of oil branded as "fuel saving" or having friction modifiers as it will not work well with wet clutches. I personally like the Rotella 15-40. You can get it al wally world for cheap and it works well with the moderate temps around here. I only put on about 3K miles a year. If I rode more or under hotter conditions, I would probably go with the Rotella synthetic. This has been discussed on the forum many, many times. Do a search and you should find plenty of good reading material.

    I use Golden Spectro 4 10-40 Petroleum base oil in the 900, I use Golden Spectro 4 semi synthetic 10-40 oil in the 1000 and I use golden spectro semi synthetic 20-50 in my Ninja 1000R and in my Hyabusa.Im having great results with both my ZL s using the oil I have described, you should do the same..

    I think many like myself used to use the Kawasaki 20w50, ran it a long time with no problems but after hearing all the good reviews on other oils, I wound up switching to the Rotella like most have and would never go back to Kaw brand now. Rotella is easier for me to obtain, cheaper, seems better for the bike all around - quieter, easier cold starts, etc. Your results may vary, but that's what I noticed about it. And like others have stated, I would not bother with the synthetic on the 900 due to the starter clutch issue that some bikes seem to may or may not have. Later.

    Went to Walmart to pick up some Rotella 15w-40 for my ZL900; many here seem happy with that brand. However, it said it was Heavy Duty Diesel oil. Is this the same Rotella 15w-40 that all of you are using or is there another one that is not for diesel motors?

    Thanks,

    Alan

    But that is the Rotella that everybody is using, even though it is labeled for diesel.

    We use this oil, because we are "mimicking" a diesel engine. Diesels are built really HD, due to high compression and other propertys that we benefit in using this type of oil. It has a higher "sheer" point. I really like the way it behaves in the "two finger" test. Basically get some different viscositys of oil you have laying around. Then place a very small amount (about the size of a ballpoint pen tip) yea...that small. between your fingers and rub them together....I learn this from an old guy...really old guy..long story, but anyway. you'll notice the Rotella in particular having a much higher "cling" and resistance to dissipate. Whereas, synthetics will get outta the way quicker that you can shake a stick. Then regular oil is between the 2.
