I've got the 2010 2SS here with L99. My manual says
"Rear Differential Fluid 75W-90 Limited Slip(GM Part No. U.S. 89021677 and Friction Modifier 1052358,
in Canada 89021678 and Friction Modifier 992694)."
Should I use the Redline? I've noted that some people say it doesn't have the friction modifier. What should I buy as a friction modifier then?
Also, what jacks do you guys recommend? I don't have any tools at the moment to lift the car up. If you could give me some Amazon links, I'd appreciate it
