Is it worth using HVO

[Little yogi]

HI< I have just been through the process of cleaning out my Diesel tank due to the dreaded bug, despite using Marine 16 treatment, won't go into the details as its been discussed many times before.

Now I have a clean tanks Im considering using HVO, having done a lot of research it looks like it has many advantages over BIO Diesel , the main reason for the possible switch is ( if I'm right ) HVO is less likely to attract the bug as it doesn't absorb water , and keeps for much longer then Bio diesel, has anyone on hear been using HVO, do you still need diesel bug treatment

What are your thoughts

HVO is the ideal fuel for boat with a diesel engine.
But apparently its expensive if it's available.

Where are you based?
If got access, or big enough tanks to get bulk delivery, it sounds a good option.
CA HVO

do you still need diesel bug treatment

You don't necessarily need to use a bug treatment in diesel.
I do use an additive in diesel which is claimed to keep the fuel system clean but its not a bug killing treatment. A lot of people add nothing to their diesel and have no fuel issues . I think diesel bug is largely a matter of bad luck when refuelling.

Not sure I would agree with that assuming you are referring to standard red as opposed to HVO, which is what I think the OP was actually asking about.

Having had fuel problems and resolution by a professional outfit I would say that treating modern diesel is the sensible thing to do and that those that don’t and don’t have problems are more likely to have been lucky given the enhanced levels of bio-fuel in diesel. That said using a treatment isn’t a guarantee but it certainly moves the odds in your favour. The type you use is also a consideration and it is interesting that the OP had problems despite using Marine 16 - I had exactly the same as we were also using Marine 16 when we had problems. The guys who sorted ours recommended Fuel Doctor as it also gets rid of water via combustion in the engine.

We run boats at work and get through more fuel than the average leisure boat so it isn’t sitting in tanks for long periods but we wouldn’t dream of not using a treatment to reduce the risk of problems.
