Review: Bought as a diesel preservative - Bought as I use diesel powered hot jet wash so keep 20 litres in a Jerry can which can be sitting for months, I read that diesel can grow bacteria which breaks the fuel down into products harmful to the engines. This product stops this from happening and prevents the byproducts of diesel deterioration clogging up the injectors 1 millilitre treats 1 litre of fuel so it’s cost efficient- and goes a long way.
Review: Used for storing diesel in jerry can. - I think its an essential product to add to my jerry can of diesel. Good brand and product. Unfortunately like most other things its a bit pricey for the size you get but nevertheless worth it as a little goes a long way! The petrol one is also very good. Will buy again and again.

## Questions & Answers

**Q: How long does it take to act? I seem to have diesel bug in my ride on mower. I but 6ml in with 20L of fresh fuel this morning, engine is still surging**
A: You have to clean or replace any filters first

**Q: How do you use this? Can you put this in your car like when you put fuel in?**
A: Hi I’m not sure why you would put this in your car.. this is an additive to remove or prevent  diesel bug when fuel is left in the tank for a long time in varying temperature. 
It wouldn’t hurt anything if you did use it but other than boats, farm vehicles etc it would be a waste for you. If you do decide to use it There are instructions on the label I think it’s 3 mls per gallon of fuel and yes you just put it in your filler hole before the diesel it’s simple and you can’t over dose
Hope this helps

**Q: I have diesel car that’s been stationary for 4 years. Can I add this to the fuel tank for the diesel that’s already been left in there?**
A: Yes, have spare fuel filters available to catch any dead diesel bug.

**Q: I have about 300L of 12 years old biesel that has gone brown from bacterial frowth , will this product kill the bacteria and let it fall to bottom of**
A: Hi Bill, I’m using old fuel about 12 year old but it is clean, just use additive to boost Cetane number, but I also siphon it through an inline plastic filter cheap to buy, rot small length of small plastic pipe and it should remove debris, maybe a few times until clear then put small amount of treatment in a glass jar and see if it removes it. Great additive but my old fuel is clear to start with. Good luck Roger
