The setup posted by Michael was 40,000 F and 50,000 R, I am not seeing anyother setup posted except the one labeled 733 set-up Salven - Turkheim.
On this setup as Julius has already mentioned the reason for going to lighter oils. This car has a VERY WIDE sweet spot, that being said I have seeing user here in the US go as much as 500,000 front 100,000 rear or even 200,000 front 80,000 rear.
Here's the general principle of a Diff as how I UNDERSTAND IT (anyone feel free to correct me)
The wheel that has the most traction gets the most power. Typically on the front while cornering this would be the inside wheel. The heavier the oil the slower the wheel spin.
This also works from front to rear, same principle applies. If the rear is lighter than the front, the rear would likely get more power loaded to that axle. The harder the oil the Harder the acceleration. The lower the traction, the lighter the oil needed.

The engine powers the drivetrain. As 1/10 on road cars have no center diff power is provided to both diffs equally (assuming the tires are of correct diameter).
Now as the diff is powered the power is distrubuted to the left and right wheel. Unfortunately normal diffs will provide the wheel with the least resistance most power. This means the inner wheel in a corner. As the inner wheel is lightly loaded this will make th inside wheel spin, thus losing all drive if the diff was not filled with oil.
Now this is where the oil comes in. The thicker the oil the harder it is for both wheels to spin independantly. From no force without oil to almost like a solid axle when 500000 oil is used. The thicker the oil the more drive you'll get, but the oil also resists the wheels spinning at differnt speeds when the power is off, so the thicker the oil the harder it gets for the car to turn in. And also as the oil gets thicker the outside wheel gets fed more power, so it will not have as much sidebite left. So thicker oil can create oversteer in the rear and understeer in the front.
There is more to it still but this is the basic principle.

Actually the diffs work a bit differently. Easiest way is to visualise it from the engine onwards:

Hi,
Yep that was the case because the 733 kit oils were way thinner than Serpent "old" diff oils I have. http://www.serpent.com/product/160000 The 80k kit oil I put to the rear for the final felt like Serpent "old" 30k. BTW, the car was really super in the end on this small/tight and bumpy track.
I don't know if anybody experienced similar with the kit oils?

Guys to let u all know i ran my car the second time and was first place all the way. I tried 3 degrees camber in the back and tyre wear is better but on one side. Seems i may have to put one side at 2.5
i had used the WC gearing right of my 720 and been using it in my 733. Only today i realised the 733 gearing new in the box is 60s 17T and 54s 22T. And all this time im using 59s 17T and 56s 23T. It will be interesting to see how it will work when i put it in for this weekend. Also the 720 flywheel wont work because it is lower that the height of the car and sticks out the chassis. I have been using it like that for my second race day, but it still doesnt touch the ground

I'll monitor how it'll hold up during this weekend club race.
Haven't really get used to the 733 and found the setup I want (ran about 3 tanks only) but who cares! Just race!! !
will try to find the right setup during the race...
