I went to the dealer in Wy. to get my oil changed while on a cross USA trip with my RV. Dealer put in 10w-30 oil when diesel supplement states that when temps are over 50 F, or towing a RV, the oil should be 15w-40. The temp at the time by the way was about 94 deg.'s. I had the oil changed immediately to the proper 15w-40 after I saw it on the invoice. While it was there I figured I would get the tires rotated and balanced since it had 6200 miles on the truck. Whoever did the rotate and balance scratched 3 of the 4 aluminum Lariat wheels. Needless to say I was sick and I must say that it has been several months since the event happened but Monday I am getting the new wheels put on. When you think the dealer is going to give you the best service for your vehicle, I'm a bit gun shy about going back to any dealer at the moment for service.

 

A lot off times these 6.0s will run much better on 10w-30 then 15w-40. I tried 15-40 once in my 7.3 PSD an the thing did not run right went back to 10-30. Quirky but true. The oil was the right specs to. Been 10-30 ever since. It must have been a shock to you to find out you had 10-30 instead off 15w-40. No excuse the dealer should have told you. These rims on these trucks are a bear to remove the aluminum sticks to that iron. I tried it myself an drove myself crazy.

 

When I remove my wheels to rotate them I brush a little Never Seize on the inside of the rim to keep them sticking to the steel hubs. Works well.

 

At 6200 miles I do not know if it was your first oil change or not, but your truck came from the factory with 10W30 in it.

JFYI.

That seems odd that it would have come with 10w-30 when the diesel supplement states that anything over 50 degrees F. should have 15w-40.
Is this a break in oil? I did change the oil myself with Ford motorcraft oil at 1260 miles only because it had been six months or better since I bought it. So to keep it under warranty rules I changed it. Then on our trip to the west coast I had it changed after 5000 miles under heavy towing through the mountains I felt this would be a good time. The dealer was a small dealer and who would have guessed that it would have created such a problem, with the oil and the scratched wheels. Which by the way were replaced yesterday at my local Ford dealer. So all is well again!

 

It's not a "break in oil." It's 10w30. That's what they put in the truck during the initial "break in" period.

 

That wasn't in Evanston, WY, was it?

 

is there a ford dealer in evanston? I didnt think there was.

 

No it wasn't Evanston, but it was in Cheyenne, at a small dealership there that this unfortunate situation happened. My wife and I spent 10 great days in Cheyenne during Frontier days and we had a lot of fun there. We saw some great rodeo action and concerts by Toby Keith and Tim McGraw, so when I got my truck serviced you can imagine what a downer it was to the end of our stay in Cheyenne. But as I mentioned before the scratched wheels have been replaced and all is well again.
