Castrol Valvemaster

Castrol Valvemaster is a lead replacement fuel additive for use with lead-free fuel.

Castrol Valvemaster is endorsed by the Federation of British Historic Vehicle Clubs and has been subjected to a valve seat recession test by an independent test house on behalf of the FBHVC. The results of the test indicate that the level of valve seat protection is likely to be adequate for all normal driving.

One bottle treats 250 litres of fuel.

If octane increase is required, see "Valvemaster Plus" elsewhere on our site.
