Is posh diesel worth it? (40 Viewers)

[Daffy64]

So come on, should I put the expensive in or say one in three times?
Just a definitive answer please, I can’t cope with all the explanations and science.
My brain hurts.

My advice would be as already said, use a std branded diesel and not supermarket fuel

I would concur with TrudeandDall - I’ve been 40 years technical with the last 20 + as the UK Technical lead for a major high speed diesel engine manufacturer.

The problem with some diesel is the bio content it can vary from 5%-20% (30% France) the bio part of the diesel contains a lot of water, the reputable suppliers will only have the low bio content, water going through the fuel system theoreticaly should be stopped by the filter but some will always get through and when the engine is not at full temp will cause carbon to build up in the exhaust system affecting the DPF and EGR valve.

A page I follow on FB talk about many things to reduce the chance of injectors failing. One suggestion is using decent fuel, another is keeping your fuel filled to the brim to reduce moisture getting to the injector tips. Nobody knows what causes injector failure but we try everything to eliminate it.
Sorry to go off topic

Diesel Bob (a diesel specialist) advised me after re-calibrating my pump to put a tank of posh diesel through once every couple of months of daily use.

What is the additive you can add yourself. Where do you get it?

Every 4th fill-up I use super/premium diesel. Just to give the motor a clean.
I do put super-unleaded in all of my bikes that have carbs to help prevent the dreaded ethanol-induced crud formation over winter. Injected bikes, I just use regular.

Running a 55 plate coach build on a 2.4 Transit chassis I use the cheaper Jet garage on our way out of town. When we are away I fill up we’re it’s convenient but always standard diesel.
The only time I use special shell diesel and Wyns fuel system cleaner is pre MOT hoping it will help with emissions. It dosnt seem to make any difference to the way it runs or the consumption.
