FORD manuel say 6.4 PSD oil change at 10,000 miles??
 

When do you guys think I should do my oil change & what oil should I use ??? I'm thinking of every 5,000 miles & using conventional oil like ROTELA 15-40.:ok1:

Really depends on what your using the truck for. If you do alot of towing I would change it at 5K.

HI LUKE, I use my truck as a car with a bed, I don't tow, pull, or race !!! I don't consider hooking a 4.5X8 trailer with a quad on it as pulling !!!

i change my 08's oil every 3000 mile's but im always towing heavy loads i thaught the owners manual said 3 to 7000 miles. 3000 miles if your towing alot and seven if your just hiway and taking it easy i read mine once but i cant remember for shure what it said all i know is at 3000 miles my oil is dark black i realise the its caused from the heavy hauling i do

I would go 10K or close to it ford isn't just guessing on how long the oil will last. The best thing is to do a Oil Analysis Gm saids 10K and I've had good test at 12K and a not so good one at 15K with the old Delo 400. Just because you oil is black don't mean a thing.

I was changing the oil on my 1999 F250 7.3 PSD every 3 to 4 thousand miles, BUT I guess these new engines burn the fuel better, and don't leave the oil as dirty ??? I'm going to change it between 5,000 to 6,000 miles, since it's not going to hurt nothing:ok1:

Oil is cheap compared to the alternatives :)

Im changing mine every 3k, and both fuel filters at every 7500.

Hey Gahanna, I bet your oil is still good at 3,000 miles, Even if you race yor truck, a bit !!

Hehe.. well, Im not completely sold on Ford's/International's claims of 10k oil changes on normal driving and 5000-7500 on heavier usage averages.

I can get 4 gals of Rotella-T and a new filter for less than $70.00. So to me, that $70.00 every 3000 miles is nothing compared to the price of fixing the damage from rolling a bearing on the rods, mains, or turbo's..... just my 0.02 cents worth :)

I see where you coming from, BUT I'm not going to be to hard on the pedal, as for the fuel filter, I'll wait till I have 10,000 miles !!

Yall do realize that diesels go a long ways before an oil change right? 5,000 miles is normal for a gas burner but a diesel under a load can go about 7-10,000 miles before a change but i go 15,000 miles in my powerstroke before i get an oil change, they say with the synthetic oil i use i could go 20,000 but i like to be on the safe side. My 08 has 14,280 miles so ill get the oil changed probably at the first of the year.

I'm not using syntheic oil, I think conventional at 5,000 miles will do all right.

The dealer told me to change it every 5k... Probably a little on the early side, but the oil has been changed every 5k, and its got 33k on it now with not a lick of problems, so I'll keep it up.

Well mine has 9500 on it and it just got its first oil change as I don't drive it that often. But I would say depends on conditions. If you drive a lot then change every 5-7500 or more based on towing, weather, etc.

i would say 5,000 miles

Once I reach 20,000 miles, I'll stop using regular oil & move up to syntheic ROTELLA & instead of changing the oil every 5K, as I've been doing with the regular oil, I'll change it every 10K with the syntheic !!!
