Personally, on newer engines - I wouldn't touch the stuff. Diesels operate on compression combustion - due to the fuel being a longer-chain hydrocarbon compound than petrol (the viscosity is higher, and the freezing point is higher (i.e. it will solidify at a 'warmer' temperature). In these days, when most talk about the benefits of using fuel additives (Cetane boosters, injector cleaner, etc), it seems ironic (and somewhat dangerous) to consider blending a 'thicker' compound and adding it to your car's most expensive component. There is potential for damage to the fuel pump, filter and injectors (in much the same principle as running your diesel on petrol).

An old motto; "Penny wise and pound stupid" should be the over-riding principle employed.

Rather than treading down a potentially ruinous road - if the cost of motoring is too high to bear - downsize/cut back on use or use alternative modes of transport.


This job should never be complete - the day I think I've done it all, is the day I resign.
