Thread: Diesel Additives

It really depends if your fuel system is dirty. If it isn't it will have no effect. If it is gummed up it might be good.

I remembering seeing a 5th Gear program on restoring power to older cars and the fuel system cleaner gave the best increase in power for five'r than anything else they did.

Anyway at $15 bucks it can't hurt.

The best additive IMO is the Chemtec diesel power, not sure how much power it gives you (probably nothing) but keeps the algae from growing in your tank.

On a 23k km trip some years ago, I noticed the fuel consumption dropping off after about 7k km. After dosing with Nulon diesel injector cleaner, the consumption would improve significantly.
Since then I have been dosing every second or third fill, figuring that it's best to keep injectors performing well all the time.
I've only used the Nulon product so can't comment on the others.

thanks

I use cleanpower (and other products) from costeffective.com.au. Per dose its cost effective (sigh) compared to other additives. (High initial cost). I believe fuel economy is better when I use it, but I don't record the data. Sorted out issues in an older diesel as well. Recommended to others who have had good results as well.

I dose every fill with a diesel additive but there have been periods where i didn't for one two or three tanks in row and my son (who's always following ) say's it smokes less on the additive and cos i do record the fuel economy i can verify that the difference is 2 > 4 litres / 100k.

Really ,onebob 2 > 4 litres /100k
So up to 1400 kilometers to a tank , what additive would that be?.

The other alternative to adding your own additives is to run a tank or two of BP Ultimate Diesel every so often. I know specialist BMW and Audi Indies who swear by it in high tech turbo diesels and say you can see the difference when doing repairs with less carbon build up.

Do your own research and make up your own mind. If you are into adding additives, then going with the fuel companies mix can not do any harm.

I personally like to chase the lowest cost diesel (but no bio-diesel thanks), but if running low and passing BP then will get a tank of BP Ultimate Diesel. Again could be another form of Placebo......

just commonly available additives - when i plug in the figures sometimes the calculator says 14.xxL/100kms (not good) and sometimes it says 10.xxL/100kms(excellent) and most times somewhere in between
