My kid brother is going though a rough patch ( long story) any way he gets very cheep diesel from work , and his oil tank at home is half full could you run a boiler on half heating oil and half diesel iv had a googel and says it burns at same temperature etc ? My mats dad used to run his car on heating oil

You shouldn't as diesel can block up the jets inside the burner ..think you can get a lot of heaters changed to run on diesel though

I’ve been told you can run them on diesel so half and half should be ok just to be on the safe side

I knew a guy who put Diesel in his tank for quite a while but was not sure if it's right so looked this up.

If you run out of heating oil, you need to u get your furnace back up and running to keep your house heated properly. Does diesel fuel work in a pinch? We'll tell you!

I have diesel central heating as do many boats, heating fuel burns cleaner than diesel so as said if he uses it for a longer period he may have to run a cleaner through it from time to time, if diesel heating plays up it’s not uncommon to run kerosene through it to clean it all out, so my advice would be short term yes but if he’s doing it regular it may lead to problems with blockages etc
