New replacement 6.0 ~$10K A oil change with motorcraft (or similar) including a fram filter all bought from wal-mart ~$50 bucks....... Sounds like a CHEAP insurance policy. Seeing a guy change his oil every 20K miles and ruining his truck....PRICELESS. Do you run your tires until the wire is hanging out of them too because its cheaper?

 

nice

 

Your not supposed to run 'em that long?

 

You can but unlike an engine with a spin on filter like a 7.3, the oil in the filter housing will drain into the crankcase when you remove the lid.
Even when you properly change the oil and filter at the same time on the 6.0, up to 4 quarts of oil is left in the engine that never drains out, then you dilute that gallon with 3 1/2 to 3 3/4 gallons of new oil with a full and proper change.
Imagine the quality of that remaining undrained gallon of oil after a few 20,000 mile oil changes

 

Seems to me it's his truck.... He can do what he wants, why's everybody so quick to dog him out. His truck, his oil, his money.

 

true he can do whatever he wants.. his truck, his oil, his money.... then again my keyboard, my posts, my opinions i for one am definitely not doggin him i just said how i changed my oil i do however think yer refering to 06silvercrew for one... and i did think it was funny what he had to say, but i don't think he meant (or anyone meant to dog him) but there were some good things said that mayb someone might look at and think "ya know mayb i will change my oil more often," or "mayb i will change it less this guy has 198k on his" i know i'll stick with 5k for oil and filter but he can do what he wants and noone is sayin its definitely the wrong thing so let's not get all mad at each otherbut the "free country thing" goes both ways they are entitled to there opinions, just like i would except negative criticism any day on somethin someone thinks i'm doin wrong... doesn't mean i'll change it, but i do not have the right to not be ofended nor does anyone the only rights you have is to life liberty and the persuit of happiness.... (or jus run to the government in our country to gain someone elses hard earned happiness) lol but hope everyone is havin a great weekend i'm workin myself and speeking of oil gotta change mine today sorry for the tangent

 

These Forums are for discussion and advice (providing and receiving). Many people have negative experiences with things on their trucks so they put forth their time to share what they have learned so that others may benefit. The benefits are for both the OP (Original Poster) and other readers. When reliability is compromised, the folks with experience are very good to point it out. I for one am very glad they do.

In the end it is all up to personal choice, but clearly our trucks are sensitive to many things other vehicles are not. When you take care of the details, these trucks are reliable

After being on this Forum (and several others) for years, you learn who you can listen to and who you have to follow up with some research. I learned that by reading all the posts that I can fit into my busy schedule.

Take Origcharger for example (since his post was last). He and I have a few minor differences in opinion, but having seen MANY of his posts, I know he has more experience than the average person with maintaining vehicles. I appreciate his insight.

If we didn't "jump on these issues" more people would think that 20k is OK and do it. I personally have looked at hundreds of UOA and 20k is a poor choice at best. Many techs here have stated that this type of maintenance causes many of the problems they see. I think most folks will say they benefit from "black and white" discussions like this.

 

nice post bismic

 

Yeah great posts, some of oyu are MUCH better putting your thoughts into words then I. LOL But yeah I wasnt raggin on him, I just was making a point. I do so much heavy line work, alot of it being on diesels, so I have what I would consider alot more experience then the average person. I just cant express enough what kind of things I get to see that are 100% due to poor maintenence, or lack there of. Especially on a diesel, some people dont understand how a diesel injector even works. Engine oil is its lifeblood....period....Oil lubrictes them, fires them. With oil that has "broken down" alot of problems can arrise. Anyone priced an injector for a 6.0 latley? I would be willing to bet an an average DIY oil change price of $50 done at a 5K mile interval, thats 20 oil changes in 100K miles, and $1,000 in oil change stuff. You cant get a set of injectors installed in a 6,0 for a grand. Ok im done rambling LOL

 

That's right! We have (7) 6.0's, from 2003-2007. We started out with my truck, changing the filter every 5K, oil every 20K, have sent in oil samples in and like I said in a previous thread........all ok, no correction needed. So, we started doing this to all our 6.0's.......( I just know you guys are going to hate this) and now were are doing this to our 7.3's. We have (9), but we go every 5K oil filter change, 10K on oil. The 7.3's seem to be harder on the oil, at least that is what we have been told. I know this rattles some people here, but these are all work trucks, the body will wear out before the motor. Sorry if this bothers some of you guys here, but it seems to be working. And a reply to how far I take my tires........at least 50K, rotating every 5K, and when I'm done with them......the tire man doesn't see any any wire.

 

This is just plain wrong - it is the other way around. I have both and I do UOA on them. My 7.3 is at 220k and doing quite well.

Also (regarding the 20k OCI) - if you have injector problems that appear to be oil related, my dealership (I have a very good relationship w/ them as I have owned 4 Ford diesel trucks over 20 years) has stated that they (and many others as well) will ask to see your oil change records. They have said that they WILL NOT honor the warranty if you do not have the receipts. Can they do it? Who knows, but they can try and make it a battle to get coverage. It just isn't worth it.

I also have not seen an oil that will maintain its viscosity range past 10000 miles (maybe even 7500) - so I question your UOA statements. Somewhere you stated that you drive a lot of miles, so I assume that many of the 20k miles are highway miles. You have that going for you - since it is not the severe "stop-and-go" service. Towing will also take a toll on the service life of the oil. If all you do is drive on the highway, your trucks seeing a different service life than the typical truck owner's vehicle.

If you feel strongly enough, please post each trucks mileage and OCI history and the UOA's that you do. In the mean time, the common wisdom from Ford, many techs, and many folks that have worked on these engines, is that the $'s saved are not worth the $'s risked (in repairs) by a significantly extended OCI.

It's only b/c after 250k miles the rings on the 7.3 are shot. The 6.0s don't last long enough to be hard on the oil

 

This is why. Here's a new guy looking for advice. He sees that post that it's OK to go 20k on his OC. Maybe he does, maybe he doesn't but I'm also with the majority here and consider it cheap insurance. Your money, your truck, and I'm not knocking you- it works for you and thats cool. But for Patrick with 1 post, probably better for you to do the recommended 5k oil and filter. But again, your $$ your truck. BTW Eddie 250, welcome back!

 

After reading this line of posts ........ in essence what some are saying that if you have a lot of experience, based on your posts on this and other boards, that your opinion should carry more weight with anyone who reads them. And if you don’t agree with a particular poster’s opinion then bla…..bla……bla. Then let’s challenge the poster to prove his thoughts/opinion/maintenance plan. OBTW - I guess if one wanted to they could fabricate all kinds of stories about all kinds of things and as long as you post that kind of stuff…… it’s fact?

Guess my thought goes back to “It’s their OPINION” I kinda agree…… some people are better at putting things into words than others.

BTW I change my oil at 5k, my brother-in-law goes to 10k, but I personally have no issues with him or those that want to stretch it to 20k …….. unless they pushed that their opinion was the only way to go.

Sorry for the rattling....
