Motor oil weight for triton v10

"WILDEBILL308".....is correct. Times have changed, engines have changed and oils have changed. A friend, who is a safety manager for Conway Trucking, often sends me trucking articles that he thinks I might want to read since I own a DP. One of the most recent articles was the switch to lower viscosity oils to improve mileage in the trucking industry. Cummins had approved the change and was allowing lighter weight oils.

In the RV world, I know I would never see enough of a mileage increase to ever care about changing my oil to something lighter, but I guess if you have a huge fleet of trucks, the savings could be significant. So things are changing.

Vehicles over 8500 lbs GVW with the Ford f250 and F350 PU's are now covered.

People can keep on writing that until the mods get tired and lock this thread, but that won't make it true. What do you think "Exempt" means? As for me, I won't spend any more time trying to convince you or anyone else.

Wiki is not always 100% on target.

Read here for the facts straight from Uncle: fueleconomy.gov

"Some vehicles are exempt from these requirements:"...
"Large vehicles from 2011 onward:
Pickup trucks and cargo vans with GVWR over 8,500 pounds
Passenger vehicles, such as SUVs and passenger vans with GVWR of 10,000 or more"

There are plenty of online dealer sites to look up window stickers. Read one for a current F-250 or 550 MH chassis and you will see "FUEL ECONOMY RATINGS NOT REQUIRED ON THIS VEHICLE"

Yes, I know, motor oil threads are like religion... thankfully we can all buy the viscosity we want. :C

Read your own link. Vehicles over 8500 lbs GVW with the Ford f250 and F350 PU's are now covered. However, it looks like the V10 is no longer available in those PU's.

When we had our 2005 gasser with the 310 hp I used the 5w20 as the manual required. No matter what vehicle we owned, I always went with what the manufacturer recommended. As mentioned, many people feel that the manufacturer is just trying to cover their butts. They test every part of the vehicle for hundreds of thousands of miles. Our new diesel pusher says to use 15w40 and change it at 18,000 miles or once a year.

So does my 2011. If you check the Ford website virtually all of the late model V-10's call for nothing but 5W20. Another vote for full synthetic oil and for the transmission - differential.

:C

So does my 2001.

This is one of those threads that comes up nearly monthly. The problem is we have a bunch who are still using what they learned in the 60s. The engines of today are not the engines of the 60s. The oils of today are not your fathers oil. I don't care what you think about the weight oil Ford calls out or what you think the reason they call out a specific weight oil. If I had a Ford V10 I would use Mobil 1 0-20. Hear is a fact the cams don't have replicable bearings if you gall or wear out a cam journal you replace the head. The tolerances used in the engine are very tight.

More recently, coverage of medium duty trucks has been added to the CAFE regulations starting in 2012, and heavy duty commercial trucks starting in 2014.

I believe you are mistaken. Can you find a citation?

Can anyone name a vehicle equipped with a Triton 6.8 subject to CAFE? Were there any vans or Excursions below the threshold?

How about some used oil analysis reporting lower wear rates with oil other than the factory recomended oil?

If anyone has any science, rather than just beliefs, let's see it.

Ford's manual states 5W-20 Motor-craft Synthetic blend.
