A very good product & highly recommended.
I put a dose into my son's 1999 Mk triton (diesel) with nearly 300,000kms up. He hasn't stopped commenting about the better starting and smoother idling he is now experiencing. The4x4 has never had any thing other than straight diesel in its tank since he became the owner about 8 years ago. We believe it has given the fuel tank and fuel system a good clean out.I run fuel doctor in my NX pajero and believe it to be good insurance long term.

Millions of people swear by this stuff, now I'm one of them. Smoother, cleaner running, helps reduce fuel contamination in-tank.
