10K or 15K?

[HSLD]

I've been doing my oil changes at 15K. I took the truck to a new shop for the last change and they recommend changing at 10K. I asked why, and was told that's what they recommend. They offered nothing to back up the reason for recommending the change at 10K instead of 15K.

What are you doing? I can't see changing anything I'm doing without anything more than a recommendation without any other information to back it up.

WE CHANGE OIL IN ALL OUR FREIGHTSHAKERS AT 15 000 MILES

SO FAR WE HAD NO PROBLEMS WITH IT AND MOST TRUCKS HAVE ALREADY OVER 500 000 MILES ON THE ENGINE ;)

i chang oil round 15k or if i can't get in after 15k go i 5k more

[Chiefwhatdahey]

If you have an egr equipped engine I would change at 10m otherwise 15m is good

If you have an egr equipped engine I would change at 10m otherwise 15m is good

question what is egr?

Well, that's what I've been doing as well. Got a 60 Series in a Classic XL with about 460K on it.

Think I'll stick with a 15K interval like I have been.

HSLD, have the shop take an oil sample. That'll give you a good 'starting point' so to speak. Then do your oil changes like you have been.

Have oil samples taken every other oil change. That'll give you a 'heads up' if something inside the motor starts to 'go' before it actually does.

One company I was leased to changed the oil on their company trucks at 30K miles (as per directed by the company that did the oil samples). That saved them a lot of money each quarter.

They were using 100% synthetic oil.

I change mine every 12-15K miles whether it needs it or not. :D

Dave, I'm having a hard time finding a shop around here that I feel like I can trust. I used my last guy for quite some time. Then, he had a "personnel change" in the shop, and follow up trips on work not completed or just not done right was really starting to kill me (and tick me off).

So, this last oil change, I called a mobile fleet service. He was going to change the oil at the yard I park at on a Saturday morning. He calls Saturday morning asking if I had something he could catch the oil in and what I expected him to do with the old oil!!!!!! So much for telling me that "you do this all the time" on the phone and that my oil change would be no problem. And this was a guy who says he does inframes / out of frames wherever the truck is parked. Of course I found out later it's because he doesn't own a shop!!!!

So, I took her to a new shop. They did a very good job on the oil change and noticed a few small items that I hadn't noticed yet. They were a little pricey, but I needed it done NOW. So, the guy tells me that he recommends every 10K, I ask why and he says that's what he recommends. Nothing else, that's just what he recommends. Guess he wants the business every 10k or something. But no real reason other than that's what he recommends. :wow:

They greased the 5th wheel with what looked like a case of grease. I can't even walk past the tail of the truck without getting grease on me! Heck, I can't hardly look at the truck without getting grease on me!!! :D

I'm really starting to realize that true mechanics are a dying breed.
And that I'm looking for a new shop to take my truck to. :zzz:

Maybe try a Speedco or Flying J (the ones with shops if there is one near you). They do oil samples for around $15.

Have one taken just before an oil change if the shop you use can't do oil samples.

That's what I have started to do now since my motor has 650K on it since the inframe.

question what is egr?

Exhaust gas recirculation basically it dumps the particulates in your exhaust gases into the crankcase where it turns to sludge and forms acids and other corrosives that eat engines up. The powers that be (EPA morons) decided that this was the latest and greatest for diesel emissions, now instead of fuel efficient and long running diesels you have poor fuel mileage and low service life junk you have little to worry about Ironeagle N14 is pre '02 EPA moron standards

ok thanks for answering my question

If your truck sees excessive idle time (more than 30%), then it's best to change the oil at 10- 12K miles.

If very little or no idle time, then 15,000 miles is OK.

Most older mechanical engines should have the oil changed at 10K.

Synthetic oil: Been there, done that with another truck I owned- NEVER AGAIN!

Synthetics will work if they are used early in the engines service life

i never will use synthitics in any vehicle of mine

[Chiefwhatdahey]

i never will use synthitics in any vehicle of mine

I'll never own a vehicle new enough to make a choice :D

well hear horur stories using synthitics and not the funny kind

[nitestar]

I do my oil changes at close to 15 k as I can. got 927,000 on her and I can't see changing now. I try to do a sample at every oil change and I try to use the J if I can. Petro if a sample machine is available. no sample, no oil change. I never use a Baldwin filter of any kind.
I have a fumotomo valve inplace of the drain plug so you don't get your watch lubed taking a sample. Mechanics love it. Just pull down and turn and presto oil in the can with out a mess.
Put one on my Pony Pack too. thinking of all the cars now.
Been thinking of the GCF , but still thinking. have to find a place for a 28in long filter housing.
decisions, decisions, where does it end?

Now I may be wrong, but when I was pulling a 55,000 pound load over Donner Pass, I was sitting comfortably in an air-ride seat, with the cool air coming out of the A/C. My motor on the other hand, was doing all the work, getting hot, and straining to get the load to the top of the hill.

Call me old fashioned, but when a motor does all that extra work for me, I don't mind doing my oil changes at 10K.

What filter do you recommend?

Well, know what I'm doing next. Or at the next oil change. Just changed the oil on my ProHeat and got to wear some of the oil pulling the plug. What an experience that was. The ProHeat Manual has the wrong oil filter #s in it. So after 3 tries, I finally got a filter that fit.

Been thinking of the GCF , but still thinking. have to find a place for a 28in long filter housing.

What's a GCF?

Tell me about it.......................................

I'd agree, but I'm not running anything hard like that. Guess I'm lucky.

EGR is indeed exhaust gas recirculation. A valve is used to control a certain amount of exhaust gas that is cycled back into the engine air intake, and burned with the fresh air/fuel charge. It has been in use in our gasoline cars since 1972.

The good effects is it does reduce exhaust emissions without dramatically harming MPG, and can also help keep cylinder head temperatures cooler.

Bad effect, as mentioned, more conatminants end up in the crankcase as a result of dirtier blowby gasses. More frequent oil changes are needed with EGR engines as a result, and as many old car buffs have found out old dirty EGR valves are sitting on the engine doing nothing.
