Review: It works - Worked perfect on my diesel golf engine ! Stopped the leak and the smell
Review: Great product and highly recommend - Had a small leak under my van. Looked this up online and the reviews were good so I thought I would try it and I can tell you I'm glad I did. I put this in and went to work the next day where there were a few drops of oil there was nothing and hasn't leaked since. It's been 6 weeks now and still going strong

## Questions & Answers

**Q: Is this a fuel additive or is it the stuff you add to oil before you drain it?**
A: Yes pour this into your oil when its warm, it's NOT A ADDITIVE for fuel.You need to mix this with your old oil, but don't drive! it's only for changing the oil.This is used to remove more sludge etc and keep your engine more cleaner.Make sure you Use for around 12-15minutes on high rev then, you MUST drain your old oil & change filter & fill up with new clean oil.I use this on every oil & filter change rarther than just draining the oil.(Works Well)Hope this was use full - any further help just ask

**Q: Hi. Does anyone know if I could use this to flush a brushcutter engine. 35cc. Thanks**
A: Hi there, it will only work with in the oil if the motor is two stroke this wont work. Many thanks Dave

**Q: Is this safe to use in my scooter?**
A: Don't see way not I use to use no my z 1000

**Q: Hi, could I use this on my 600cc motorbike, if so how much of it would I have to use? Cheers**
A: Use it all, but check the instructions before you do!! Run the bike till the engine is nice and warm and the flush has had chance to work, then drain, change the oil and filter and your done. Sometimes you can put the flush in and run for a week of normal use, but personally I haven’t been brave enough to do this! Good luck.
