Daytona Gear Oil

Would Royal Purple Max-Gear 75w90 be the correct gear to use in the Daytona box without additive given its limited slip differential?

Drew,

it's the correct oil, but the Daytonas are known to chatter like crazy at slow speeds in tighter turns, so I've been using additive for years and it Does help.

So, would you suggest putting in a tube or two of the GM limited-slip additive?

Drew, That's exactly what I've used for years the GM Addative in the tubes. Try one and if you still have some chatter put in the another tube. But no more than two.

Regards, JRV

Got it.

Thanks.
