Thread: Diesel conditioners

Alright there declan,
Why are ya looking to put that gear in the motor for in the first instance?
What age is your vehicle ?
And are you getting any symptoms to make you want to do this ?

Don't use anything in the Isuzu's

Probably not need, modern ULSD is pretty clean (<10PPM of sulphur these days, which I think is equivalent to Euro diesel and is less than the diesel sold in the US)

If you do want to use one, not many IMO can back up their claims, but Redline market a couple (eg RL2, Diesel Plus) that have been tested extensively in the US and don't impact on the bottom end and oil. Mechanically injected diesels may benefit from the increased lubricity from regular use of a good one that has added lubricants in the form of ashless esters.

Many fuel additives, through blow by, enter the crankcase and can break down the oil and be be quite corrosive to bearings long term. I've seen their results straight away in used oil analysis.
Redlines additives don't appear to have any impact at all on the bottom end.

I was told very strongly by a well known diesel specialist to stop wasting your money on fuel addatives and spend the money on replacing the fuel filter/s every service. He seemed to think that dirty batches of fuel are the main offender. For example; have you checked your water trap? A small amount of water running through you injector pump isn't going to help.

I have also read an article in one of the recent 4WD Action mag's about how to avoid getting yourself some contaminated diesel from the servo. It went along the lines of, don't go there when or just after the truck has just been to replenish the servo etc, don't be fooled by the cheapest diesel in town either..... etc

just my 2cents
Cheers
Brian

Thanks for all the replies lads if you don't have to put conditioners in the Diesel that's great I just wanted to do the right option for the engine to keep it in top condition ,my Defender is a 2006 110 Defender and I interned keeping for a very long time.

Thanks Declan

|West End Diesel (respected Sydney diesel experts) recommend a little Fuel Doctor (its green) with every tankfull. They have a very interesting, and convincing, video on their web site (Fuel Doctor, that is).

Wasn't there another article on here (maybe it was Defender2.net) saying that vehicles fitted with EGRs will benefit a lot from an occasional dose of fuel system cleaner as a way of reduced carbon buildup on the EGR valves? Plus same article advocated the occasional lashing of right boot.......

Any diesel benefits from a good, long, hard flogging
