[dannyk13]

Creosote?

[scorpiojo]

Creosote anag to scooter

[dannyk13]

to scooter has two 't's Jo

[dannyk13]

And three 'o's

[scorpiojo]

There's always a catch ;o)))

[scorpiojo]

Scooter + o (new additive)?

Poor clue

[dannyk13]

Yup

[Captain2]

Is it 'scooter' + E (additive)?

[dannyk13]

Still too many 'o's Jo :-)

[Captain2]

... as in 'E numbers' (additives?

[elliemay1]

anag scooter + e(additive)

[scorpiojo]

Danny misled me with the 'three o's' ;o)))

[dazza89]

It's an anagram of scooter. Then add e as an additive, which gives us creosote

[Captain2]

Go on, blame someone else. ;0)))

[dannyk13]

Profuse apologies

[scorpiojo]

:o))))
