Ford was always crazy, I guess they're certifiable now. I know its not Ford wanting this, they're just trying to goody up to the EPA since they've been making so many trucks/SUVs for so long burning 1gallon of precious bangjuice every 10miles.

Police departments RARELY run 5W-30 in their cars.
your cop friend most likely had no clue what they run in the engine - just from a friend of a friend said this and that...
Most departments run 10W-40, 15W-40, and other crazy but heavy oil weights to compensate for oil burning through the valve stem seals.
So what was that about 15W-50 spec'd for the 4.6 DOHC V8???
Ford is crazy to recommend 5W-20 and my iron clad sources do not recommend 5W-20 at all. 5W-30 is the weight to use in the high tech SOHC and DOHC 4.6s... NOT 10W-30.
The guys with 450+ hp AED Blown 4.6 SOHC V8s still run 5W-30 w/o any problems w/ street and strip driving.
Keep in mind cop cars are idling 95% of their life - so you cannot compare them to a Stang. Again, this would be super inconsistent testing like that virgin oil analysis comparing 15W-40 to 10W-30...
My Crown Vic has 4.6L SOHC V8 and it is not driven like a cop car at all (idling most of the time, slow cruising, etc...) whenever I take it out for a spin I try to hit 5600 RPM as much as possible (dyno-tuned). Its only got underdrive pulleys, revised intake, and revised exhaust - but its still peppy w/ 3.55s in the back. 0-60 in about the mid 7s
keep in mind its not a fast car, and its a 4200 lb 4-door sedan.
BTW the "exploding" Crown Vics are caused by moron police equipment installers WHO DRILL INTO THE GAS TANKS to bolt down equipment.
Ford rear ended a Crown Vic at 80 mph with a test car and nothing blew up. No flames, nothing. Just two mangled cars. That bad press is just that -bad press. Its not the truth.

one of my friends who used to be a LEO in the central US said his dept changed the oil in the 4.6s every 2500 miles with "Mobil 1 10W-40"
I never knew Mobil 1 made 10W-40.
I've also heard cops say they have 460 CID V8s under the hood (and lo and behold, a standard 4.6L SOHC V8).
I wouldn't go by what the officers say at all (about their cop cars). Ask the mechanics what they use.

All 351s were pushrod motors, and this is definitely old technology that would handle a thick 50wt oil pretty well. Although if I owned one I'd run 15w40 most likely.

I'm still confused as to why they say no 10w30, but yes to 5w30. When it's 90F outside these two oils will flow pretty much the same. Even when it's 40 or 50F they'll flow the same. At super cold temps they might be a hair different, but not all that much. And like I have said before, a 10w30 synthetic (or blend like Schaeffer) will flow better in extreme cold than a 5w30 dino anyways.
5w30 is not as good as 10w30 because it shears back (thins out) quicker in a lot of cases, and it also doesn't score as high on the Noack volatility scale either. And it uses more VI improvers, so long term use with 5w30 means your engine will not be as clean as one using 10w30 would be.
Simply put, 5w30 is not a high performance viscosity. When you're revving to 6 or 7000rpm do you want an oil that shears back so easily? I know I don't, and I'm only making 275hp.

One more thing. None of the heavy hitters with LT1 and LS1 f-bodies run 5w30. Or at least a very small percentage do. I guess f-body owners are just smarter than Mustang owners?

It depends on which 5w40 and 10w40 you are talking about, because a 5w40 like Delvac 1 doesn't shear back, it's a very strong oil. And a 10w40 like Redline also doesn't shear back.
But generally speaking, the wider spread oils like 5w40 and 10w40 do thin out quicker.
An oil like 20w50 won't thin out quickly, despite it's large spread, simply because it starts out with a much thicker oil to begin with, and uses less VI improvers than a 10w40 or 5w40 would.

I was looking for the factory fill synthetic thread the show Metro what is put in he Supercharged Cobra but could not find it
Got this little ditty off the new Conoco-Phillips site:
"ConocoPhillips also sells gasoline under the Coastal brand in 14 states and under the Exxon and Mobil brands at 1,900 stations in northeastern states."
Sooo... ConocoPhillips is really Exxon and Mobil in some locations as well as Coastal. And don't forget Union 76. I for one am thoroughly confused as to who will be making what with all these shakeouts and consolidations. Just for the hell of it, here's the specs. for TropArctic 10W30 dino:
Typical Properties: Values are representitive of current production SAE Grade ------------ 10W-30
Stock Number 42860
Specific Gravity .8667
Flash Point COC, C (F) 222 (432)
Pour Point, C (F) -36 (-33)
cP @ -25 C 4936
cSt @ -40 C (104 F) 70
cSt @ 100 C (212 F) 10.16
Viscosity Index 139
Sulfated Ash, % 0.8

Yep Chris, that looks like it. But, of course, I have "issues" with Castrol's business practices so I tend to leave them off my "top" lists.
Just bought some Chevron 5W30 Supreme at Walmart. They had been out for months. I only left 2 on the shelf ... and they won't last long.

Your cracking me up! Read the words,it was a State Trooper "Highway Patrol Car " and I just ran across him at the gas station and if the motor had not been making noise I would not have asked anything.FWIW I did not type that some of the cars get Pennzoil depending on which Lube Center is designated for the Trooper through use of State credit card. State highway Patrol cars drive down the highway,,they don't idle 95 percent of their life,,a better oil should have been used in them but the State does not care,,they are throw away cars because of sufficient funds. If they were smart they would use a synlube and run the miles up,,,but whoever said Oklahoma State Government was smart ?
You "Iron Clad Sources " would flip out if they new I sent my Mother and her 4.6 on a 4200 mile trip to California and around this summer without it blowing up
csandste
That oil is ine if thise that will go into 20wt mode quickly,,they at least offer another 10/30 for performance cars of sorts.
Chris,L8274 uses the now removed from the lineup 10/40 Trop Artic SJ Turbo oil with 30 percent PAO and Synergyn additive,,the oil was shipped from a wholesaler here in Oklahoma along with a few cases of SJ 10/30 Trop Artic Blend,,I got the rest of it
( These guys might become a site sponsor- they carry Euro Pennzoil Quaker State and Castrol along with other Conoco/Phillips oils and ship Aviation lubes Nationwide )
I do beleive the Motorcraft oils should be thrown into the mix of OTC dinos.It is 1.17 for a single quart while Castrol GTX is now 1.79,,not to pinch pennies but we always are talking price vs performance. A ford truck did well in TX summer heat in alot of traffic with the 5/30.
Bror,I understand where you are coming from and do not use a yellow bottled oil anylonger for my personal reasons,,are we biting our nose off to spite out face? Nope,there is always another way to get a job done and lube a motor with good results
So what is the best oil ? The one each member choses I guess,,not especially the oils that some self proclaimd proffesionals advise you use here on this forum,,one mans oil is another mans junk
Oil is like camming a street performance or race motor,,not a one size fits all thing

I worked 31.5 yrs for the goverment and we were mandated to use the cheap quick lube places, state police, etal. They did not care what oil went into the vehicles as long as it was not synthetic, only tht it be done no less than 5000 miles and what the cost was. The places had to be in the system, and they had to call for authorization for everything. I accidently put in Amoco 92 octane in my truck once and got called on it. They have all the maint. budgeted into the cost of the vehicle. We had WEX fleet cards, had to enter miles or hours each time card was used so they new every dime we spent with our credit cards. Only thing with the police was brakes, they had to be done a state certified facilites using certain brands, NASCAR type brakes. Only trouble is they a penney wise and pound follish, for instance. Could not charge a headligth on the credit card whoch would have cost $10-15, had to take it to Chevy dealer and pay $45. They figure you could put the light in your car, I guess?
