Does Amsoil Severe Gear 75w140 require the addition of a Limited Slip additive?
Specifically asking for a 2015 Ram 1500 w/ LS rear diff.
Used ASG 75W/140 in my Mustang and son’s F150
Both needed a small bottle of LS additive
Had more chatter in the F150 than the Mustang, but one bottle was the cure. So might was well add it from the beginning and you’ll be good to go
