Mine has always been changed every 5k since new.

Is it sufficient to get to operating temp for just a few minutes and then turn it off? I probably get it out on longer runs about once a week - maybe less.

 

Im betting that alot of people use theirs like this, I know I do.

I run it for about 20-25 minutes of driving then turn it off.

 

Also another important feature is to use your block heater for when the air temperature is 32F (0c) or less. When we are at -40ish I have the heater on a timer to come on about 4 hours before startup. With this mehod the preheat does not even come on. Electrictiy is cheap in this case.

 

The greatest wear comes from starting the engine. Long haulers put more miles on between starts. Low milers don't.

If you really want a long lasting engine, put a pre-oiler on it. Those run a pump and get the oil pressure up and flowing before you even turn the key.

If you don't get the oil hot enough to burn off condensation, change it more often. Expect to go through mufflers, cats and pipes more frequently for the same reason, they are full of water every time you start the truck. It takes heat and time to burn that water off.

 

IF Mr. Sturgeon has some advice...I'll darn sure listen. This man knows his stuff, whether it be cars or business. He knows me not, but he is an inspiration to me. Thanks for the post!
