Just want to confirm that the Lucas Oil "Heavy Duty" 80w90 is OK to get for an 05 5AT G35 Coupe rear differential. Could not find Amsoil anywhere and the Royal Purple 75w90 was $20/qt. Lucas was about $6/qt

Thanks

 

another option: http://www.redlineoil.com/product.aspx?pid=133&pcid=4

i run that, it's a full synthetic and cheaper than RP

 

Thanks for the heads up. They didn't have the Redline fluid.

I had the shop put the Lucas in the differential last night when it was in for an oil change.
