A combination of additives to clean and maintain the diesel fuel system. Prevents corrosion, increases lubrication thus reduces fuel pump and injector wear. Increases Cetane value for improved engine performance, easier starting and lower emissions. Regular use keeps the fuel system in perfect working order. Suitable for use in all diesel engines, with or without turbochargers. Safe for use with catalytic converters and particulate filters (DPF). For best results add Super Diesel Additive every 2,000 km (1,200 miles) to fuel. Contents (300 ml) is sufficient for 2575 Liters (7 gal. to 20 gal.) fuel.

I've already bought this Stage 1 kit once before for a used 2010 Q7 TDI, and just now for a used 2015 Q7 TDI. I can tell you that you will feel the difference in engine response and power, engine noise reduction, and see it in the overall efficiency and MPG gained when you use this kit of additives to supplement the correct oil type/spec for the vehicle. If you've ogled it a few times and still on the fence about buying it for your TDI engine...BUY THIS TODAY. Be aware that it does take a bit of driving time for the Ceratec additives and fuel system purges to work their magic on you TDI fuel system and engine efficiency. Just follow the simple directions on what to add where and when to add it (hint: they don't all go in at the same time), and you will be well ... MoreI've already bought this Stage 1 kit once before for a used 2010 Q7 TDI, and just now for a used 2015 Q7 TDI.

I will definitely follow this up with the Stage 2 kit on both cars we own as it noticeably improves driveability/responsiveness of the vehicle and improves fuel efficiency while reducing internal engine wear. I think it's a small cost to pay for a better day-to-day driving experience and excellent fuel economy. The effects and benefits of the Ceratec treatment last for 30,000 miles and the Stage 2 kit is meant to provide additional efficiency benefits once this primary treatment has been applied. Highly recommended!

This review is for my 3.0 TDI bro's, if yall have a high pressure fuel pump .. specifically the CP4 .. this is the additive you are looking for. I know its little confusing since Liquimoly has alot of diesel products that are tailored for different applications, but this is the one with the diesel lubricity additive. This will save your HPFP from self destruction. Buy these in bulk, use as directed, you'll thank me later. I really wish they would had a follow up video specifically talking about the HPFP issue, and how this protects it.

This is a great product to use every other tankful in your TDI, as directed, just to keep things clean and the HPFP happy. I mainly use it as a supplement whenever I fill with diesel at a non top-tier fueling station. I always try to refuel with top-tier diesel, but if I can't do that, or get a 'bad' tank of fuel from a station, then I'll drop a can of this additive into the fuel tank to boost the Cetane values and lubricity of the fuel, etc. You can hear and feel the difference in the engine response, as well as in how it literally 'jumps' when you prod the throttle...zero hesitation. It's a good investment used as directed...HPFP's failing can be very expensive to repair, but the main thing is your TDI will be very 'perky', and return excellent fuel economy, which ... MoreThis is a great product to use every other tankful in your TDI, as directed, just to keep things clean and the HPFP happy.

Second time I've ordered this Liqui Moly Stage 1 bundle to perform a maintenance reset after buying a used Q7 TDI, and again, it does not disappoint. This kit really gives you exactly what you need to clean everything out and help the remain trouble free and operating at peak efficiency. To get the most out of this kit, refill the motor oil with Liqui Moly oil, which will result in a quieter running engine. Having tried several other brands suggested by Audi, the Liqui Moly oil is the only one I will use going forward.I really think this kit is a strong investment in the future health and longevity of the engine. We changed all filters & fluids in conjunction with this kit, and couldn't be happier with how well our two TDIs run. We did see incremental increases in ... MoreSecond time I've ordered this Liqui Moly Stage 1 bundle to perform a maintenance reset after buying a used Q7 TDI, and again, it does not disappoint.

We changed all filters & fluids in conjunction with this kit, and couldn't be happier with how well our two TDIs run. We did see incremental increases in fuel economy measured within 1000 miles of using this kit on them...that's the Ceratec kicking in. Both cars are bone stock and 'emissions fixed' TDIs and return approx 6% better fuel economy than in my fuel economy tracking pre-kit. If I slowed down a bit to reduce wind drag, I believe it would jump to 10% gain or better, but that's exactly what makes it so impressive to see a 6% gain since nothing else has changed in regards to driving habits/usage, fueling, etc. We don't 'baby' our TDI's; we enjoy them.
I am happy with the noticeable performance improvement.I really can't tell how well the detergent cleaned my fuel system and engine combustion spaces.
Well I got a great deal on this used car as an unscrupulous repair shop told original owner it needed a turbocharger due to a noisey wheel hub bearing. As it was a little bit down on power I decided to run the Liqui Moly Super Diesel Cleaner along with as strange as it seem clearing baked on residue from inside the sticking turbo vanes with oven cleaner while letting it soak and moving actuator and respray. Figure this will prevent that from happening again as it will prevent the build up in the future
Parts always shipped on time. I like very much the fact I can get the 'White Lable' (produced for BMW as OEM) parts made for my BMW.
I have only seen good reviews on this kit for long term engine wear reduction and improved performance for the Audi and VW TDI 3.0L V6. I looked for a video or instructions for using Diesel Purge, but only could find one for the VW 4 cylinder TDI. I performed a search on the FCP Euro website, but found nothing. FCP Euro should add this to their DIY video series.
OM617 motor seems to be more responsive when Liqui Moly Super Diesel Additiv #2002 is infused into a fueling my vehicle with a full tank. Only this brand's Truck Series Diesel fuel additive is superior, IMO
My old 1982 240D Mercedes Benz runs like new with this additive! It's the best thing I have ever used to keep the injectors spraying like they did when the car was made!
