I bought one about 35 year ago and put it into an old Triumph Dolomite 1500HL tank...brilliant...quieter,smoother and more mpg..done the same to two 2.0 Ltr Cortina's..brilliant again...WHY..I don't know WHY !..but nothing else was altered at the time and the cars ran much better...Anyway i have just put one in the tank of my old 1999 Honda XL600v motorbike that i have owned for 5 years..Always run very nicely anyway and more than happy with it...but for some reason fuel cats came up on my ebay ? SO I DID IT AGAIN..AND .. Tickover now improved, IS smoother to ride PLUS I and i'm a complete weirdo that checks mpg on all of my four vehicles every time i fill up and am absolutely positive now that this bike is doing about 5 mpg more for the last 3 fill ups doing exactly the same journeys, since dropping in the tank...SO..for £23 quid for the smaller bike version i am dead chuffed with the differences...one night in the tank and the next morning i was gobsmacked at how the tickover was totally better when stone cold and didn't have to fiddle with the choke lever anymore...BRILLIANT...WHY ? So i phoned the guy that sells them, who also makes them, and with honesty he tells me not to fit then in my newer cars...BRILLIANT AGAIN...and helpful...SO I AM A SINNER TOO !

This is a 13-year-old thread.

A: I've tried it and it works.

B: I don't understand how it can, so it doesn't.

A: I've used it in two cars, and it definitely works.

B: It can't possibly work, so you are a liar or a charlatan .....
