curious, how many miles between your oil changes on diesels?

 

i'm a bit **** when it comes to my vehicles. i change my oil every 3000 miles. use shell rotella. my truck is an '05 psd with around 35000 miles on it. hasn't been to the dealer since the day i bought it! changed the fuel filters at 15000 and 30000, the air cleaner at 20000 and drain the water seperator regularly.

 

Every 3500 miles here, fuel every 15000, air every 20000, diff every 50000 and trans service every 25000. 82k miles and some change.

 

Oil and filter every 5,000 KLM (3,000 miles). Drain water seperator every oil change. Air filter at 20,000 KLM (12,00 miles). Rotate tires every 15,000 KLM (9,000 miles). Still a baby at 30,000 KLM (18,000 miles).

7.5k as per owners manual

 

4500 to 5000 miles. blackstone oil report every other oil change.

 

5000 blackstone every 10,000

 

I have mine done every 7,500. If I were to tow/haul daily I would do 5,000. Just like the manual says.

I just had my first Blackstone done at 77,600 mi. With 7,500 on the oil, my report was as good if not better than most of the 5,000 interval reports I have seen.

 

What were your viscosity numbers?

 

Every 5000 miles. I used to do the 7500, however I idle my truck for extended periods now.

 

Every 10,000 miles now weather it needs it or not!!

 

Here is a link to the thread I posted on my Blackstone.
