Diesel Fuel Additive

Guys,
Got talking today about fuel conditioning and was recommended this product by a friend. Anybody else use it or have comments. I know of one WK2 owner who swears by it decreasing fuel consumption with a bit more grunt.

DT5 Plus Diesel Treatment (5L)

Re: Diesel Fuel Additive

I haven't used the product you referenced but it does look good on paper.

Having tried a few for my WK2 I have settled on liqui-moly diesel boost atm. Another product I like is redline 85 plus for the CRD which looks similar to what you want to use.

In my td5, well it has good old 2-stroke at 1:200 ratio.....

I wouldn't mind trying 2-stroke in the WK2 as guys in Europe still praise the same benefits in their CRD's, ie quieter idle, smoother engine and so forth.

I'm 3 tanks into opti-lube xpd. I've been putting in 8oz for a full tank. So far so good. For me it's all about mpg and smooth operation. The GC is so smooth to begin with, and I love the slight diesel chatter sound.

So, I was avg 26+mpg for the 1st 3800 miles. Have 5200 on it now. Jeep is 6 weeks old. My last 2 tanks I'm avg 27.2 mpg. I'd post a pic but I don't know how. I haven't reset mpg and only reset the trip which shows mpg for tank and for all 5000 miles.

Very impressed. If there is something wrong with this thing....I'll find it. I drive 50k plus per year.

Re: Diesel Fuel Additive

I've run in to a sizable quantity of free Fuel Doctor (conditioner/injector clean) and ran the shock treatment initially followed by 250ml per tank for the last 4 fills. I can confirm there is a noticable improvement on pickup and fuel consumption is slightly improved, (7.6L/100 on highway).

Re: Diesel Fuel Additive

I've run this in every other tank since new.

DIESEL KLEEN® +Cetane Boost®: Max HP Formula ? use during non-winter months for the ultimate in performance.

Tanks with it average about 1.5mpg better and the engine is noticeably smoother. The added lubrication agents are also good insurance should you run into some lower quality diesel.

I used to run it in my Audi TDI and i would consistently average 3mpg higher with smoother running as well.

I buy it in the large jugs and then just refill a 16 oz container when needed.
