I know some of you used amsoil severe gear lube with slip-lock additive for your limited slip differential.
I have just received following message from AMSOIL:
"You are correct, the lookup guide is confusing and we’re looking at options for clarifying the friction modifier statements in the lookup guide. Briefly, the Severe Gear oils are friction modified and will work well in most cases without additional friction modifiers. However, due to varying degrees of wear, current clutch material condition, spring strength etc… we cannot say definitively without a doubt that additional friction modifier won’t be needed in some cases. In the limited cases where chatter does occur, ADA would need to be added.*"
I have dilema, because I have already purchased amsoil lubricant but didn't change oil yet.
Could you share your experience in using this lubricant with or without slip-lock additive in GM vehicles w/LSD, especially CTS RWD 3.6 DI FE3.
I am affraid my LSD will be no more limited slip if I use additive or will have chatter in other case. Can lack of FM cause differential damage?
