Volvo D13 Oil Change idea

Hello everyone, I currently own few Volvo trucks with D13 engines. I am using Mobil Delvac 15W-40 Conventional oil and changing it around 10.000 Miles.

I know that Volvo recommended oil change interval is around 25.000 Miles when using Synthetic oil.

I prefer changing the oil much often but that comes at a cost of oil, filters, and labor.

I have recently started thinking, what if at 10.000 miles mark I change just the oil (drain and fill) and at 20.000 miles I change oil and filters?

Since Volvo recommended interval is so high that means that the filters are designed to withstand 20-30K miles and when changing the oil at 10.000 miles the filters probably don't use even half of their resource.

What do you guys think?

 

What you are saying is right but it doesn't contradict me either. Those who use Synthetic oil change the filters more often because the oil outlives the filters. In my case I am looking to use conventional oil and change the oil at 10k and filters at 20k, same filter interval as those who use synthetic.

 

Factory recommends using Synthetic oil, you can't expect the same mileage from conventional oil.
