0W-30, yeaa? Noo? Go for it?
I have been running Mobil 1 5W-30 Synthetic for a few years in my 460 engine, but I noticed Mobil 1 is also carrying a "0W-30" oil as well. It claims to be compatible for 5W and 10W applications, while providing better lubrication and fuel mileage (don't worry I'm not doing this for fuel mileage). Anyhow, I bought 6 quarts of it, but before I did the oil change I wanted to see if others have used the lighter weight oil too?
I went onto Mobil 1's site, and for some reason they recommended I use a 20 weight oil? Is that right? Heres the link. My truck calls for a 30 weigh oil though. Are they basing that off my 148,000 miles, or the fact I choose I wasnted "Optimum" protection?

That is BS
I decide to put my 93 F350 in there with miles. They say I need 0w20.
They try TRICK you so you fell their trap to use 0w20 in your engine that supposed to have 5w30 or higher.
what happened 0w20 is too thin so few miles it get worst thin due hot. Then your engine seizure.
I would stick 5w30 to 10w30

I put 0W-30 in my dads truck, which is a 1999 with a 4.6L triton. Do you suppose it would be okay in an application like this?

Best bet is to stick with what the owner's manual says. Newer motors have much tighter tolerances, so 0W might be OK in a 4.6. I've never owned one so I don't know what they recommend for them.
For your truck, I would stick with 10w30 and unless you live in a really cold climate it's fine for the winter too. I live in Sacramento and it never gets real cold here so I run 10w30 synthetic year round.

I have never had issues running 0W oils in any of my engines, BUT, I run diesel rated 0W40, never tried a lighter weight.
I run it year round in my diesels, and used to do it seasonally in my 460. If you don't need the 0W for cold winter startups, you probably won't notice much of a difference, other than cost.
Personally, I absolutley would not go with a lighter hot weight than is reccomended by the manufaturer. While your 460 is new model year wise, it isn't design wise, and these old engines were not designed with tolerances that like 20W oil.
If you aren't having leak issues running the oil you are now, I would be worried about it.

Amsoil recommends 0W-20 (or their "signature" 0W-30) for the 460 as well.
I recently "got on the Amsoil train" and put it in my car and bikes. Now it's time for an oil change in the truck ('93 F250 7.5L) and I was just sitting at the computer looking at the Amsoil website thinking "man 0W-20 sounds awful thin".

BTW. is there a reason why my oil turns pretty dark blackish right after an oil change? It started doing this after I gutted my cats last summer. Since then I reinstalled hi flows cats. Maybe I have a bad o2 sensor? running a bit rich?
