Motorcraft Oil?

[AW794]

I always have run this oil with zero problems. Went to walmart today to get some, and they didnt have any . Then went to another walmart, and they didnt have any either. Is something going on with the motorcraft diesel oil? Seems to be hard to find around here lately. I bought some Rotella 15-40, as i know several other members run that. I never have used it before, so i guess we will see.

Walmart has a good price on that oil and it seems to sell out fairly quickly. If you talk to the guys at Blackstone Laboratories they'll tell you that pretty much all oil is the same, it's mostly a matter of brand loyalty rather than performance value.

Delo 400 for me and my 09 PSD, seems to be the favorite round here an it is $8.50 a gal here at wally world!!!

You'll be fine. I run Rotella T 15w40 whenever I can't find Motorcraft 15w40. They're both good oils for the PSD.

My Walmart had Delo 400 for $8.50/gallon last week.

My Walmart had Delo 400 15w-40 CJ-4 for $8.50/gallon last night. I have never used it before but this is the truck's first oil change (2800 miles) so I want to put dino back in until the rings seat, whenever that is. I couldn't resist the price given its reputation.

"Dino" oil is not going to seat your rings any faster than synthetic motor oil.

The only advantage synthetic motor oil has is the ability to produce a flatter viscosity curve vs temperature. 5W40 is practical with fewer viscosity improvers. Viscosity improvers are weak and do not last as long as the base oil, so having fewer means the oil stays within the viscosity specification longer. That is most of the basis for extended drain claims for synthetic.

15W40 is the standard for refined Diesel motor oil as it can be produced with minimal viscosity improvers which results in a longer life by staying within viscosity spec.

There are thousands of fleet managers monitoring diesel engine wear. If synthetic motor oil reduced more wear than its added cost then refined motor oil would immediately be past history. Same goes for extended drain, if it cost twice as much but went twice as long then it might be accepted. Synthetic vs refined is not a religion for fleet managers, but operating cost is.

Running the Rotella and think it is a good choice for these trucks

I saw at a local walmart they have Rotella 15W-40 for 12 bucks for 5 quarts. The same price as motorcraft oil. I think Rotella is a better choice of oil especially after I talk to my local ford dealership shop foreman and he said he would use Rotella over anything else if he had a diesel. Too me I don't think what oil brand you use as long as you change it every 5k miles.
