Jesse M · **Heavy diff oil bad for motor? -** 08.06.2009, 04:20 PM

I always thought that running thicker oil in the center diff and the fr/rr diffs puts more strain on the motor resulting in higher temps all around. I also thought that putting something like 120k in the CD would transfer more power to the rear wheels resulting in more wheelies, the opposite of what Brian said "taming the wheelies."

I'm running a Losi 8T with the 2200 combo and am looking for the best setup. I strickly drive on asphalt. I currently have 10/30/5 and it is accellerates very fast. Talking to engineers at Castle and others, they told me not to go much higher than 30k in the center diff due to the added strain on the motor. They also told me to go a little heavier in the rear if I am strickly bashing on asphalt-to help the rear end break loose a bit in
corners (more fun).

I have some 120k laying around, but don't want to compromise the life of the motor. I'm running 40 series road rage tires, so maximum transfer to the rear wheels is ideal.

Any help on fr/ctr/rr diff oil thickness for street bashing is appreciated?
