Default Re: The Fuel Additives Thread

Hello Everyone,

I have a 650 kms (one way) drive planned, mid December, I have read quite a few posts about Liqui Moly Diesel Additive. I have ordered a 250 ML bottle of "Liqui Moly Speed Tec Diesel Additive" from Amazon today and plan to use it before the trip starts. Vehicle is 3 year old XUV 5OO which is done around 30K kms till today (yes it run low comparitively!). I am contemplating of pouring the entire bottle for 70 Ltrs of fuel. Hope this would be ok!

You could add it when you top up the tank before your trip. One more thing you could do is an Italian tune up. Drive at high rpm close to the redline on an empty stretch for a KM or so

I like the term Italian Tune up. Things are not as bad as they used to be. As a student in the UK, 1973-76 whenever I went on the Motorway after pottering about town for a fortnight or so, when I opened the throttle the car would hiccup once or twice, before clearing up. Was it the lead deposits from the fuel?

Just added a bottle of STP injector cleaner to a tank nearly full of fuel. Treats 50-60L but I reckon the car had about 45 litres in it. That should help clean the injectors on my trip next week. I use STP every year or 5K kms whichever occurs first.

Used 350ml of ABRO DT-508 Fuel Treatment on a full tank on my Aspire diesel.

It has been just 25 kms and initial impressions are good. The idling clatter of the engine has reduced quite a bit. The engine note while on the move is a bit muted now as well. The full effect will be known on the highway. I was using Shell V-Power on highway trips and it made a similar difference, but on the last trip it did not work, so decided to try this.
As per smoothness, the engine is just crossed 7k kms, so I couldn't make out any major difference in smoothness apart from the idling.

Italian Tune Up is one of the many new things I have learned after becoming a TBHP Member !
The hiccup and blockages is most likely due to carbon deposits.

Well i have used both liqui moly diesel additive and system d.
I can compare them and i would say liqui moly did nothing to my sx4 ddis, it just made my engine noisy and the car would feel strained.

Then on suggestion of bhpian anurag, i tried system d and it did make quite a difference to my car.The car pulls cleaner and since then am using it regularly.Almost three tank fulls and i plan to continue using it regularly.

Like @SGIITK has said and I think so too - after initial use, you can switch to alternate tank-fulls or wider ( 1 in 3 ). This is because the system would have attained a level of cleaning and after that it just needs to be maintained that way.

I was a bit skeptic about these fuel additives but a recent experience has changed my opinion.
I was out of country for a month and my bike was not used for almost a 1.5 months. I remember the last time I had filled her up at an Indian oil pump. So after almost 50 days I took my bike out (its a fuel injected bike) and it started off well just to start dying when the rpms would fall below 1700 rpms. It was having hiccups intermittently, as if the fuel lines are clogged and the cylinder is not getting enough fuel for combustion.
I reached the office keeping the throttle above 3000 rpms at all time. While leaving office I put two sachets of ADON P at an Indian oil bunk and started off. The bike's behavior improved, it became a lot smoother (as expected) and the hesitation on throttling was gone too. I rode the bike after emptying the tank and filling normal petrol again after a gap of 15 days and there was no hesitation this time around.
So in my opinion, I feel the additives do play some role in cleaning the fuel system and dissolving the gunk that forms when the engine is not working for a long time. It might also be due to the fact that my bike has been sparingly used and its almost 7 years now, with no fuel injector / pump cleaning done.
