Sorry if this has been asked before but I cant seem to find any threads (may not be doing it right). What is the general thoughts on oil. Getting my first oil change since owning the car. I have only put 70 miles on the car myself and need to get the oil changed before putting it away for the winter. Car has been sitting for 4 months getting total restoration and I am used to cars using synthetic oil but want to be sure with a Turbo set up that I take care of the GN correctly. Thanks for the help.
