10W30 for Powersmokes?

[Schrowang]

There was a letter in the RV Clinic & Performance section of Trailer Life this month that was interesting.



The writer was complaining about his poor mileage on a 2006 Ferd F-350 dually w/ a 6. 0L Powersmoke. His "mechanic" told him that a switch from 15W40 to 10W30 "diesel" oil would give him a 2mpg increase. He began using the Motocrap 10W30 diesel blend oil (whatever that means) and claims to have gotten the increase.



For my money, the payback on the increased mileage may help him replace his engine, somewhere down the line.



BTW, there was a stock answer from the TL columnists; quote, "However, make sure that the oil and its viscosity range that you use are both recommended by the manufacturer for the temperature expected while that oil is in the engine. " Good advice.



If Ferd is recommending Motocrap 10W30 "diesel blend" for their Powersmokes, maybe they're trying to wipe out their red ink with increased engine sales?



Interesting, huh? :--)

Motorcraft 10w/30 diesel lube

At the Moultry, ga. Farm Expo this past fall there was an exhibit

put on by a Ford dealership from Tallahasse, Fl. and they were

recommending the Motorcraft 10w/30 diesel lube for the new

6. 4 L engine. The attendants seemed to be very informed about

the Motorcraft products and the new powerstroke. Also they were

pushing the Motorcraft fuel additives to additionally lube the

new fuel.

I don't know who packages Motorcraft these days, years

ago it was Texaco Havoline and I have run 10w/30 CD/SG in a 5. 7

litre diesel during the winter and spring months, never had a problem

with it either, of course it was Havoline. Motorcraft, Mopar, John deere

super 50, all of these oils are processed under the specifications of the

manufacturer under an agreement that it can not be copied. It's not likely

that you'll buy a better oil unless it's a synthetic.

Kind of off topic, but interesting:

My neighbor (a mechanic that works on diesels) buys nothing but Powerstrokes. On one of his recent trucks, he took it to the dealer for an oil change & they installed 10X30. While towing his toybox, he blew the engine. Since he had an Edge box on, the dealer would not honor the warranty so, he had to rebuild the engine, himself.



After the teardown, I got to see the engine parts & the bearings were scored, badly along with cylinder walls, pistons & rings, etc. He went with over sized parts on the rebuild & it worked OK, afterwards. He thought a lot of the damage was because of the oil & he had two used oil analysis done to verify what was in the engine at the time of its destruction. He traded that truck in on a new '05 or '06.



The new truck is now on its second engine & third turbo.



In the trucks defense, he beats his trucks, to death. Says that they are diesels & should be able to take the abuse. His first 7. 3 Ford went through 7 or 8 transmissions (auto).

I looked at one of the 08 fords yesterday. The diesel option alone was $6895. The auto was another $1100. Amsoil's series 3000 diesel oil is a 5w-30. I ran it for a while in my 95 dodge.

If you use a 10W-30 "DIESEL" oil that has been formulated to the API CI-4+ specs. there is no reason not to use it!
