Picked up my truck today after another front crankshaft seal, and on the work order they added 1 gallon of 10w30 Motorcraft winter diesel oil to my 15w40 Castrol Tection Extra that I just changed last week! I talked to the tech he said not to worry. Should I dump it or leave it in?

I would have THEM change it... They sould have contacted you before doing so or just charged for an oil change..

Leave it and don't worry. I can see no reason to even consider dumping the oil, the weight was fine for this time of year it won't hurt what is in the crankcase. The tec was doing a complete job by checking the oil you should thank him.

If you think I am going to call you to get permission to add oil to your truck your nuts especially when it's in for a warranty repair. You would probably be the one to tell us it was a gallon low after you picked it up if we didn't add the oil. You got to love these warranty customers.

And how was the tech supposed to know what kind of oil was in there to start with. He did the right thing.

[/ QUOTE ] I didn't take it as a attack. sorry if that's the way it came across.
There is not enough time in the day trying to get a hold of customers that can't be gotten a hold of, wrong numbers, they don't work here any more, I am sorry this number is not in service any more and the list goes on and on. I was working on a truck one day waiting to get approval from the owner for the repairs it needed and the guys cell phone was ringing all day, so I answered it and it was my service writer trying to call the customer at the number he gave us to contact him that day. Stuff like this just slows the whole repair process down for other customers which one of you may be next in line. At a small shop I can see where this may not be a issue but at a some what large dealer it's a major issue.

Makes all kinds of sence.. why do the reps make a big deal out of mixing wts? I wouldt be afraid to run it at all. my appoligies fmt not ment imply all dealers are incompetent. He woulnt have known what wt of oil..

Personally I don't like mixing oils but who knows what is in there. Full of mixed weight/brand of oil is better than 1 gallon low on oil in my opinion. If I shipped the truck out 1 gallon low on oil and my boss got a call from the customer about it I would be buying a gallon of oil and driving my personal vehicle on my time to the owners residence to install it and take the BS that goes along with the mistake. My boss is a kool guy but he is very customer oriented and wants the job done correctly the first time if it can be fixed correctly the first time, ops back to that 6.0L thing again.

[/ QUOTE ] AllenInNE, If I can quote you from a old post " The only dumb question is the one that is not asked " Just wanted some feed back on this , there's not much talk about mixing different weights of oil.

they are just covering their butts. You'd be surprised at some of the OUTSTANDING UOA's that certain people end up with mixing various brands/weights of oils. Yes, there are risks if you go willy nilly with the mixing. But if you take the time to understand what you are trying to achieve, self mixing can sometimes be worthwhile. This is NON-PSD specific, but a general and common case in point is people taking 4 quarts of Mobil-1 10w-30 and mixing 1 quart of Mobil-1 15w-50. This blend on a regualr basis outperforms 5 quarts of Mobil-1 10w-30 by itself. I'm not gonna get into the specifics why because it will draw this conversation out much farther than I feel like going at the moment. And to add a specific PSD example. In the very recent past, a UOA was posted over at BITOG. It was a blend of Mobil Delvac-1 5w-40 and Mobil Delvac 1300 15w-40. The UOA produced was one of the best I have seen for a PSD. Anyway, I think that's enough for now.

WOW! /ubbthreads/images/graemlins/eek.gif That totally blew me away. Whenever one of my inspectors screws something up or a job comes back to them with a defect they missed, I make them write themselves up. I get almost zero repeat offenders that way. But they know I love them and I'd do anything for them.
But having to go to the customer's home to make it right on your own dime tells me he is really serious about customer service their first time through!

FMT, I think I almost got a glimps of your secret unbridled passion for working on the 6.0!

DieselDog,
What about your responsibility here????? I sure don't want you doing my oil changes if you leave your truck 1 gal low on oil!!!! I agree the tech was trying to keep you from having further problems down the line. I am sure you also got a good visual inspection from this, because the tech was probably thinking you had a major oil leak someplace. I myself would be to ashamed to admit that I let my truck get 1 gal low, especially after only one week.

Hi Diesel,

Yes Sir, I know I come off a little on the brash side now and again, but I'm old and I've earned the right. :>)

I've been twistin' wrenches since I was 6 years old and always get a kick out of this "oil" topic and the way folks get caught up in it.

Fact is, this is a purely "human" choice and humans do get "attached" to their vehicles. I also noticed a few years ago, that after the sticker prices climbed above $20K for a silly pickup, folks then really started being "picky" about their "babies". :>)

But in all reality, that engine could give a fig less what kind of oil it is running.

It is innate; it is nothing but a chunk of iron and it has no opinions or feelings. It is a piece of machinery and at 200 degrees or better, after coming in off a four-hour pull on the interstate, when you pull the drain plug, believe me, all oils, I don't care what the weight, make or type, will come outta that pan having the consistency of water.

Like the Ford Tech said, sure, mixing oils is not the thing one would choose to do, not the perfect practice and not operating "by the rules", but its not endangering the truck in any way either and the level in the crankcase far, far out ranks the need for being "color and weight proper".

That fella just spent 4 hours under a hot, stinkin', knuckle bustin', swear-word enticing diesel and his very last thought before he closed the hood was to make darned sure that the oil level was correct and where it should be. I would have given the guy a tip. :>)

Now, just don't get me started on that silly "CPS" debacle. :>)

If you think about it, the PSD blends a little of the old with the new every time you change oil. If it really hurt anything, International would have devised a way to completely empty the engine instead of leaving a couple of qts in.

[/ QUOTE ]NChornet, I just changed the oil last week, it was a VERY small drip coming out of the crank seal! It was full when I dropped it off at the dealer, he must have lost oil changing the crank damper and seal, front cylinder cover & the oil pump cover. /ubbthreads/images/graemlins/mad.gif
