LSD Debris 2
9th November 2003
Not much to be said, see for yourselves: -
There appears to be not must debris, no shining color. This particular oil is Castrol EP 140 (SAE 140 API GL4) {mineral} added with Red Line's LSD Friction Modifier. It has traveled around 15,000 km with some sprint test but no drifting. Is still very sticky and semi-transparent when picked-up from the oil catch tank. All in all seems effective for local climate as rear axle oil. Much better than the Castrol LSX (SAE 90 meant for LSD).
However closer inspection reveals that: -
To my maddest surprise the debris is so much and so weirdly sticky, they actually stick to the bottom of the tank. The tank was thoroughly cleaned before used. From the inspection scratch it also shows that the amount of debris is so much it actually forms a very thick layer.
This calls for closer inspection on the neodynium magnet stuck on the wrench - initially thought there was little to no debris. It was thought that nearly all of the debris was stuck on the axle's oil drain bolt's magnet. It was very thick and plentiful.
Notice after a cloth was used to disturb it. There actually is allot of debris, so much that it is saturated and cannot further attract other debris. This is very shocking :(
Finally: -
Sorry about the bluish color, stupid camera !!!!
Anyway, you get the idea. Initially I thought of using 75w-140 fully synthetic, but now perhaps not. Probably stick on mineral 140 and change it every month. Keep the used oil and clean it using huge big normal magnets :) seems like more surface area contact is more useful than magnet's strength.
