Has anyone used this motor oil listed in the newbonneville.com Performance Oil Change Kit at newspeedmaster.com. I will soon do my first post dealer oil change. Have heard farrrrr toooo many different ideas on oil for the TBA. Mobile, AMSOIL... Just wanted a little info. Price $48.00 seems not too bad when considered the filter and oil plug gasket are included. Or I may completely wrong. AMSOIL is 9.50qt online and $10 at the dealer. Or would I be better off just going down to the local Advance or NAPA or Pep boys???
