Castrol
I've heard people talking about hoe Pennzoil and Quaker State with the parrifin builds up sludge and what not. and how Valvoline is better because it doesnt have parrifin(which i use). but the person who had this engine before me always used Castrol and i was just wondering what it had in it?. and one more thing, i assume that Quaker State and Pennzoil have parrifin in there for a reason, so what does Valvoline have instead? thanks

Valvoline uses zinc instead. I'm not sure about castrol. I am pretty sure that it doesn't have any in it by the way it looks in peoples engines who run it. It's kind of hard to tell what castrol uses since they are not an oil manufacturer but just a bottling company. I do know that a bottle from one box can pour out either lighter or darker than oil from another box. At the lube rack I work at part time we always compare when cracking open a new box. Only once in a while it is a big difference.

Castol, as pretty much all oils that I have seen, uses zinc as an Anti-wear additive. Although zinc only really comes into play once you've lost your oil as it is mainly the last line of defense for metal to metal contact.
I can't imagine anyone replacing parrafin(wax) with zinc. Since I don't know anything about this parrafin debate, I'll stay out of it from now on....
But I believe this parrafin must have something to do with the base stock and not an additive, but like I said, I don't know.

I think you are on to something. Back when I was a kid (70s) Quaker State and Pennsoil were touted as the best because they were from Pennsylvania crude. Seems there was something special about that Pennsylvania crude that no other sources had. Maybe that is the parafin and maybe in the olden days, when oils were not so high tech, that parafin was an important, if not needed, additive, but sounds like its time is now past.
INLINE SIX POWER!

Yeah, last I heard parrafin was WAX!
Yes...I'd need a filter, some wiper blades and a few quarts of wax impregnated cheap oil for my 40K truck please....

[updated:LAST EDITED ON 16-Jan-02 AT 05:51 AM (EST)]I've been using Castrol for years in my cars', trucks , both of my road bikes
and my dirt bike
with no problems yet.
Don't know what's in it, but works for me.
From what I remember, MOM used parifin(?) wax to seal her jars of jam
when she canned.

Guys, next time you are in your favorite automotive supply section, pick up several brands of oil and look at the bottom and see where they come from, very interesting.

You should read the post titles "Hey Greenpus, about that paraffin...".
I think it puts to rest all of the rumors about paraffin and the so-called "wax buildup". The think the wax-buildup is an old tale that never dies.

Its important to note here that all dino motor oils are paraffin based as a natural constituent of crude oil. Its also important to note that virtually all major brands of dino oil made today use Hydrocracking/Isodewaxing to remove natural impurities in crude oil.As for why some dino oils are more likely to cause sludge than others,I can only speculate that basestocks made from crude oil obtained from certain geographical regions like Texas may have more impurities in it than oil from other sources.Or perhaps maybe some oil manufacturers use more effective detergent and oxidation control additives.I was under the impression that Hydrocracking made it possible to produce a good base oil even from so called "sour" crude but this may not be the case.Of course engine sludging is widely caused by neglect and running the oil too long.It can be difficult to determine whether neglect or inferior oil is the cause of sludging.Right now I personally use Pennzoil with purebase,and probably will continue to use it as I`m really not convinced that it causes sludging any more than any other leading brand.

I think you are right sludging occurs when dino oil is used beyond it's capabilities. This can occur in extreme heat, or using it too long between canges. Sludge is a byproduct of heat and oil breakdown most likely. That is why synthetic doesn't cause sludge, the temp range is so much higher so you never get to breakdown. I seriously doubt any of the major brands of dino oils used within specifications cause sludge.
