Oil Change

[kinghawg98]

Pardon the igornace...New to the diesel thing.

I've read the oil will last 7000-10000 mi....but should one change the filter before all the oil is changed?

I have some horribly filthy oil right now and I feel the new filter is going to clog up lickety split....

can I change the oil filter without having oil pour of of the filter housing?

Havent tried or looked or done the first oil change since I purchased the truck....so, thanks for the help!

I change my oil at 5K miles and not a mile over. Just my personal preference and habbit, I care about my truck too much to let it run with used and abused and OLD motor oil. Personally, I would never go over 5K with conventional motor oil. I use Shell Rotella 15W-40 all year round.

The oil filter is on top of the motor so no chance oil will pour out. I change mine between 4 and 5 thousand miles.

i change mine every 3000-3500 jsut for the fact that oil/filter is alot chaper than a dam motor and runnin stacked chips the oil gets pretty dirty and some long idles in the morn also yes ur oil might be good till 5k but is it really worth that extra 2k for the damage ur motor is gettin because of broke down oils BTW i run rotella also

Oil is fine for 5K miles, the original poster was asking about oil changes with 7-10K mile intervals. 7-10K is way too long, 5K miles is more acceptable.

7K is fine if your running a synthetic oil. THere are loads of people on here that run there oil for long past that 15-25K/1year drain intervals on all stock equiptment. THey might have a special oil filter but nothing in the sorts of bypass. I've run mine for 10K got a UOA and thye said change it cause I was running B100(some blow-by).

do what u want but if ur pushing 150-200 more hp throught that motor than what its designed for and working it hard obvisly u will break the oil down faster im just sayin i change mine a 3k - 3.5k cuz i do some idleing and the chips 7k is pushing it wth ur basic oil for sure

the manual for the motor recommends 7500 mile oil and filter change.with conventional oil not synthetic.i change mine at 7500 miles. i bought the truck with 32,000 miles. 67,000 miles on it now. i run the superchips flashpaq now and then but that only adds 100hp on the top setting.seems to be a matter of preference.

3k-5k. My preference.

Due to the oil shearing nature of the 6.0L engine 5K on conventional or synthetic is pushing the envelope. The 6.0 will shear a 40wt oil to a 30wt oil very quickly. Synthetics a little more due to the base stock. If you're going to do extended OCI's then have an oil analysis run, but for an extra few dollars you can change the oil completely.
