Best oil for a 460

Yes even if you are cheap synthetic is worth the money, you pay more for the oil but it lasts a lot longer, saves fuel and makes your engine last longer saving money in the long run.
My suggestion buy a good 5W30 blend and see how that goes, does it leak, noise, oil pressure, etc. If all is good then after 3000-5000 miles(when black) swap to 0W30 Mobil1. If all continues to go well use it from then on at a 5000-7500 interval(also when black).
I say Mobil1 cause it's a pretty darn good synthetic for a good deal and of course they make a 0W30, few others do. While not the absolute best oil it's a great bang for the buck cause you can often get a very good deal on it. The major stores often do a 5qts of Mobil1 plus a Mobil1 filter for $30 deal.
At each oil change add a zinc additive, look for a Zinc or ZDDP replacement.

WOW TWO 15W40 recommendations without nearly enough info.
Me, I use Rotella T6 5W40 and fram filters in my 460, I find it's the best compromise, why;
- Synthetic, likely a class 3 but a 5 would be more expensive
- The 5 is better then 10, 0 would be better but is more expensive
- The 40 is cause my engine is worn out, my oil pressure in gear idling when hot was too low with a 30.
- It's a diesel oil with more zinc(this is up for debate with rotella now)
- It's cost effective
Fram:
- I dig the grip
- Has drain back valve
- I have no need for a high level of filtering
- Buy them on sale.

X2 on the Rotella T6, I run it in my WRX (high output turbo 4 cyl) and it's done great. My UOA from Blackstone suggested I go from the suggested 3,750 mi interval to 6500. I also use a Purolator Pure One filter since the bypass pressure is very close to the OE Subaru filter spec of 26psi. Diesel oils are very robust and have a high level of detergents and soot suspenders in it, along with ZDDP.
This handy article breaks down the SAE viscosity ratings:
Motor oil - Wikipedia, the free encyclopedia
In a nutshell, during the summer you'll be fine with Xw-30 or Xw-40 type oil, whereas if you live in a region with cold winters you may want to consider a 5w since it will flow better at a lower temperature than a 10w or 15w. To blindly dump in 15w-40 and call it a day where I am would be a poor idea, since the expected high temperatures will be near zero. The engine will crank slower and the oil will not flow as well as a 5w or 0w oil would.
Adding additional zinc additives and other things won't really net you any benefit, especially on a truck with a roller cam. On a high performance race engine or one in a muscle car it may be something to consider.
FWIW Ford suggested 5w30 in almost everything on vehicles built prior to 2001, afterwards they changed it to suggest 5w20.

I can't really say what is the best zddp additive, I have yet to do more research on it. Google it, lot's of info out there. Let us know what you find.

Oddly enough most diesel oils have more zddp, but the vast majority of diesel engines have roller camshafts, go figure.

In my 95 f150 roller 351 I run cat 15w-40 and I change it at 3000 mile intervals give or take a hundred miles or so and it seems to be doin really good. The truck has 112,000 miles on it with damn good oil pressure to boot! We have two 7.3 strokers and we get a good deal on the cat oil at $25 for 5 gallon so I just use what the other trucks use.

Anyone want to make a bet on how long his oil pump drive shaft will last?

I run a semi synthetic 15w40 with a Motorcraft filter in my 93 F250 460. My truck has 178xxx on the ticker. Has service records since new. Was always at Ford and had 10w30 put in it. I change it every 4-5k or once a year(truck only used to tow or haul camper), doesn't burn or use oil.
I've had a few E-350 box vans come in my shop and had a sticker from Ford/ Motorcraft to use a 15w40 on the 460 engines. In my opinion the 460 is a heavy duty engine and needs/ deserves a heavy duty oil.

Well yeah it's not like anything has changed since 1999
Pop quiz, what is the difference between 5w30 and 10W30?
