Default Shock oil weight

What is a good weight for shock oil for a tsunami?

I bent a shock on my new tsunami(along with this and that,Oh WELL-can't plow into a culvert pipe full bore without damage) and pulled it apart and straightened the rod and the shock oil was real heavy in it.I have 40 here and used that,but looked like the original oil was almost like grease?
I was looking at tower and they have 140 as the heaviest,I think-this is to heavy,right?
Just a quick education?
thin oil would do what for handling?
Thick oil would do what for handling?
Thanks Buddy-also thinking about you wife,best

I found this and thought it would be helpful for some people on changing out the diff fluids and what thick and thin does.

Front
Thinner :

increases steering into corners (off-power)
if oil is too thin the steering may become inconsistent, especially it can lose forward traction (and steering) during acceleration out of corners

Thicker:

increases stability into corners during braking
increases steering on-power at corner exit
.................................................. .......... ........................
Center
Thinner:

front wheels unload more during acceleration
decreases on-power steering (reduces oversteer)
easier to drive on rough tracks
if a high-power engine is used you could waste too much power and sometime “cook†the oil in the center diff erential because it “overloadsâ€

Thicker:

more all-wheel drive effect
better acceleration
increases on-power steering (reduces understeer)
better suited on high-bite, smooth tracks
car can be more nervous to drive especially if a high power engine is used - you might need to be smooth on the throttle

.................................................. .......... .........................
Rear
Thinner:

increases cornering traction
increases steering into corner
Thicker:

decreases rear traction while cornering
reduces wheelspin

thanks doug, she's home and doing a little better every day, maybe we will be meeting up when the weather gets better

thinner oil will dampen less but absorb shock more

thicker oil will dampen more but absorb less shock, better for hard driving and jumping

thats why i suggested med-med/heavy, good for off roading, bashing

I have 37.5 in my tsunami and it seems to be the perfect balance between not being too hard or too soft.

Too thick oil will make it bounce and it wont recover as quick. Too thin oil will bottom out easily.

Thank you-I have 40,would that be OK?
When I took the shock apart the oil was like STP-that heavy,does this sound right???could it be because the shock was a little cold?

try it out and see, its about medium weight, cant hurt to try it out, make sure you clean out all of that old oil first.

OOPS-thanks--didn't do that <G>
But the shock is history-I think? the rod was bent in half and was leaking a little after straighting the rod and putting it back together .I can't believe how well this Tsunami held up in the crash...just the shock,bent the bottom A frame rod(which I straightened with no problem) and blew off the side of the body(fixed but not pretty lol)--but to my shock didn't break any arms-etc-and man I hit this hard
It was very cold out-I think that is why the body broke,,anyhow have shocks and body on order
Going out and bash it with my 16 YO grandson Saturday-might have to order more parts Saturday night LOL-I show no mercy on things with wheels LOL
