changing the oil on my buddies 76 cutless supreme and was wondering what type of oil should i use and how many quarts? it has a 350 in it and 113,000 miles, wondering what a good brand oil would be to use, thx fellas

 

I say Valvoline, or Mobil clean 5000, anything conventional. Either way, stick to 10W30. 5qts should do it.

 

alright thanks
