Is it first use ? How much overdose ? Was tank full ? Etc, etc. I wouldn't worry, just wait until you have filled up twice, then carry on as usual. As long as you don't overdose every fill, no sweat. I use a big Hypodermic Syringe to squirt addative in tank. **Q: Hi can I use it (maybe just one off) to 1:100 ratio? That is 500ml bottle in my 50liter tank?** A: 500ml to a 50 liter fill up makes that 10ml to each ltr making that 5 times the recommended dose suggested by hydra,would suggest contacting hydra directly for technical advise to make sure that at those ratios it wont have a detrimental affect on injection pump seals or injectors internals depending on what type of system you have either an older rotary mechanical system or a modern high pressure common rail system . there is also a possibility that the ratio suggested could affect the way the diesel fuel ignites in the cylinder on compression which could result in piston, cylinder ,or even valve damage ,suggest hydras advice first before using at that ratio,hope this answer is helpfull ! ## Frequently Bought Together - HYDRA MAXIMUS fuel injector cleaner, 1 Litre treats Up To 500 L, for cleaning diesel injectors performance enhancing diesel turbo cleaner additive for diesel fuel EGR valve cleaner diesel engines - HYDRA DPF-24 DPF Cleaner - 3x250ml treats up to 180L.
