Miles Between Oil Change
 

i was thinking or running syn amsoil and was wondering how many miles every one is running it before a oil change and how many miles between a reg oil change-non syn

thank :hellox:

i go 5 thousand on my ole 1st gen you ought to go by what your owners manual says but heres some more info too https://www.dieselbombers.com/ford-p...-best-oil.html

thats the problem i dont have my owners manual

I go 3 thousand. But the recomended is 5000 for diesels. So between there.

I was thinking the 06 was somewhere between 5-7.5k. With the amsoil, you can run 3x the OEM interval, which is 15-20k approx. This is doable. I just changed mine at 27,000. I test it every 5-7k and it was finally getting a litle built up in soot, up to 3.5%. 5 is the threshold but decided to change it anyway.
If you ran the filter too, you can do 15k intervals with them both. That's a nice distance and makes it worthwhile.

thanks hey heath trying to figure out who would test my oil any suggestions i know im in a diffrent place than you dont know of any body that i could get that done by and what do you have them look for in the oil samples

Actually most people have to sample it and send it off. Not many can find a lab locally. Blackstone labs is very popular and we do have a testing center as well..Oil Analyzers. Those kits are order thru amsoil.
Our comes with a TBN, but I think you have to request it with Blackstone. TBN is a good number to see. It dictates the life of the oil as far as acid fighting ability. Once it drops to about 2, it's time to change it out.
Other indicators are wear metals to make sure excessive wear is not occuring. They also measre contaminats as well as water and fuel dilution.
OA's are a good idea at least as a one time check to see how things are progressing and make sure nothing strange is going on.

With synthetic, I'd go 12-15k. Here is my oil analysis results with the oil change intervals/miles.

I go 3k with rotella t,everyone else goes 5 but o well

I go 5k w/ Rotella T also and I would too, with Amsoil unless I had better filtration than stock. I think Amsoil makes something that has two filters sort of like a FASS fuel system, but for oil obviously.

Any oil you run will become contaminated with soot so I think (correct me if I am wrong) the emphasis should be more on the filtration than the oil. Right?:humm:

PPE makes an centrifugal oil filtration kit, looks pretty cool, synthetic oils dont break down nearly as fast as conventional oil, but rather its the soot and contaminants that will do the damage to your engine, an oil bypass kit helps to eliminate that, therefore you can extend your oil change intervals, as long as you test your oil to see how its performing, you could go... 20000, 30000, 100000 as long as the oil is still doing its job:pca1:

Yep. That's what I referred to. Filter the oil really well. Get that soot out of it and then realize the benefits of synthetic in terms of long lasting viscosity and quality.:pca1:

I always go 5k never anymore though

2,500 TO NO MORE THAN 3,000 DELLO 15-40 WORKS FOR ME

under 5,000 is a waste of money IMO, but thats just me.

The factory reccomendation for normal oil for a Duramax is 10,000. I do between 5,000 and 7,000 on our farms stock trucks.

On my truck I change it every mile or so.

Its not necessarily the oil that goes bad, trucks go hundreds of thousands of miles on the same oil.

thanks for all the input

i run chevron delo 400 in my rig. when my info center says oil need change is when it done. which is about ever 7500 to 10,000 mile or once ever 6 months.

I agree, Chevron Delo 400 syn whenever the DIC gets to about 10-15%.... it gets a new fuel, oil and spin on trans filter at that time as well

fart smellers!
 

i belive everyone has their own opinions,beliefs, and stories, overall we seem to have a very educated group of people here thats great! i know diesels run cleaner so intervals can be longer its incedible to hear 20,000 +, i also belive in 5,000, the oil always looks good enough to run in an oil consumer, the type of oil used seems to make differences to me does anyone use lucas? i use max life in EVERYTHING, exept polaris and harley,i use lucas motorcycle oil in it it stopped the leaks!:c:

oil change
 

Something I have noticed, is the oil pan has a upward curve fwd of the drain plug, so for the last 3 oil changes I use a suction hose through the oil drain hole, over the hump, to the front of the pan. I can pull at least 1/2 quart of dirty oil out! Just something to look at...Chris

Whaaaaaat?
 

Sounds like somebody's not Off-Roading enough to mix all that oil up!!:tu:
