Changing Oil

[trouble]

  Can someone tell me what type ,and grade of oil I should use in my 440 6 Pack?I live in New Jersey, and I will only drive the car about 500 miles in the coming year.

I can only make a suggestion as choosing an oil is like choosing gasoline. I my self use Royal Purple. I also use Royal Purple for all of my fuids. http://www.royalpurple.com/homea/homea.html
I have a friend that uses Castrol full synthetic.

if you have more than  4000 miles on the engine since rebuilding it Synthetic is the best
 the problem with new oils is the lack of Zinc & phosphorus , Royal Purple & Redline have high quantitys of both , I have been using Castrol SYntec 5-50 for a long time as well. You can also add the Zinc & phosphorus by adding Gm EOS or Comp Cams has an additive as well

[Theskrich]

Do you still need oil with zinc after breakin?  What if switching to synthetic?

[Chryco Psycho]

yes you still need ZInc & phosphate to keep the lifter & cam lobes apart under high load
 most synthetic seem to have enough additives in them but it varies with each manufacturer

 :clueless:My car has been driven about 3,500 miles since 1999. Can I still use Castrol SYntec 5-50?If not what oil do you recommend.
Thanks Al

15w-40 Shell Rotella diesel oil, daily driven, comes recommended from me.

5-50 castrol syntec  is a good oil Mobil one Redline or Royal Purple are all good too
 or any name brand oil + EOS or Comp Cams additive

I think it's all personal prefence... I only use 10w-30 Q-state dino because of using for it for 25 years, all ways works good, no problems,cheaper.. my buddy will only buy Penzoil because thats what our fathers bought...There is too many darn choices now....5-10-15-20-40-50 uggghg. Maybe someone can enlighten me why to try something different?
Maybe we should start the dino vs syntec vs blend chat.........
