Is this a fuel additive or is it the stuff you add to oil before you drain it?

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

Hi. Does anyone know if I could use this to flush a brushcutter engine. 35cc. Thanks

Hi there, it will only work with in the oil if the motor is two stroke this wont work. Many thanks Dave

Is this safe to use in my scooter?

Don't see way not I use to use no my z 1000

Hi, could I use this on my 600cc motorbike, if so how much of it would I have to use? Cheers

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.
