Diesel Fuel - are there options?

Drover, what kind of truck do you drive? Does it have all the emission shit like EGR, DPF etc?

Most ULSD diesel fuels now contain a lubricant element to replace the role that sulpher used to play in lubricating injector pumps.

yep, that's what the injection technician told me: fill in good fuel, replace fuel filter every year and put nothing extra into your fuel systems; and it will run trouble-free far long.

A Volvo FM12...420HP lovely rig to drive and being a 2001 model it doesn't have the latest crap hanging off it, no AddBlu which may do wonders for pollution but makes refuelling just that little bit longer and I still get the same km/lt as the newer fancy vehicles, just costs less per Km.

Regular filter changes on diesels will save engines along with clean fuel.
But with it hitting $1.50/lt petrol looks good............................

Changing the filters too regularly is not always "good" for them contrary to popular belief.

A filter usually works (filters) better the dirtier it is. You will find if you plot filtration vs flow when brand new the flow will be at its highest but the filtration will be at its lowest. As the filter is soiled, the filtration will improve but the flow will decrease. Eventually you will reach a point where the filter can no longer support the fuel flow which is required of it - this is the proper time to change the filter.

Air filters are the same.

I hope your not serious Yom.

This might be so if your using a sieve as a filter, but a quality filter is designed to provide the correct filtration straight from the box. If a filter is run to the point where it can no longer support the flow required, then there is a very real risk of forcing contaniments through the filter.

Changing filters regularly is far better for an engine than not.

Compared to the cost of an engine, regular filter changes and using quality fuel is very cheap.

Am serious. Was required to be thrown into the mix to challenge conventional thinking as changing a fuel filter every 10,000km is a waste of time and money.


PS: am also serious, but will come down alot to the media the filter is made up of - paper weave for example are screwed the moment they see water (even when brand new and clean) and will let particles through way larger than they're meant to. The only way anything will make its through the filter media is if the media is damaged or or the particles are small enough to get through the weave (in which case they shouldn't really hurt things).

Its call preventive maintenance. With the quality of fuel being questionable in many areas ( at times there is no option but to fill up at a small servo ), the cost of a filter and the time to fit it is bugger all. It can do no harm but potentially save a lot.

Quality filters are a must. The fact remains though that a quality filter will provide the required filteration from new. By running until restricted the filter will experience a large negative pressure on the outlet side. The filter medium can then distort, which causes damage and can allow the contamination to force though. This can happen to any type of filter.
