its the viscocity. the more viscous, the more 'locked' the diff is.

the 100,000 is actually 100x more viscous than the 1000??
why would you want that??
can someone exlpain how this works, i have no idea about diff oils.

i guess the mumbers are times the viscocity of water. so say water drips (just making up numbers) 1000 times a minute through a 1mm hole, a diff oil with a viscocity of 1000 will drip once a minute. the stupidly high numbers are for larger scale cars like the HPI baja, because it needs a thicker oil in the diff becuase of the increased powerm, and car engine oil is measured in the hundreds of thousands.

Without getting too technical, diffs work by transferring more power to the tires that are losing traction. So, look at the center diff. When you are on the throttle you may see your front tires baloon up. Thats because they are losing traction and the center diff is sending more power to the front. This actually slows your accelleration some. By putting a thicker fluid in the diff you slow this action down some and it keeps more power to the reaer giving you more bite. Too thick of a fluid though and you will get too much power to the rear causing the rear end to become loose and breaking free. This is cool if you want to do donuts but in racing you want to find a good balance. So, start with maybe 5k in the center and go up or down from there until you find what feels right. There is alot more too it than this but it will give you the idea. Do some reading and you will get it. Hopw this helps.

just made by mugen. you can use any fluid in any car, but they are all SLIGHTLY different. i beleive someone made a chart of shock fluid with the three main manufacturers on, and at the high end they were all miles away from each other.

Yeah!! In buggies we usually use something like 3-5000 front, 5-10000middle and 1-3000 rear . I use 5-7-2. The bigger numbers are for monster trucks and larger scales.
You can use any brand in your buggie. They are all more or less similar, but there are slight differences between one brand and another. Check out the charts in www.TWF8.com.
