For those of you who have leaded heads, is there any preference to which additive to use? I was looking at the millers power plus as Miller's seem to be a decent brand? Adds upto 2 octane numbers too?

I've always got into the habit of using it, octaine booster one, but then I haven't fitted my wideband yet. I may try the stuff benross recommends. |

I would rather use one tbh, A new sensor is a lot cheaper than a new head lol, the tetraboost looks good, but it is bloody dear, there's enough to treat 640litres of fuel, don't think I will even get close to using that much lol Audi s4 b5 - 470bhp & 486ft lbs

I don't think lead replacement additives contain lead, and will be ok with lambda sensors.

The castrol does seem good value, about £11 for 250ml, that will do 250litres if fuel, whereas the Miller's at £8 only does 40litres to 250ml.

Im using Castrol Valvemaster with the same head as you Craig. I was told its important to use it from the off set with a new head, due to newly cut seats. You need to choose one brand and stick with it, as they all work slightly differently. I contacted Castrol, about wideband sensor, and was told it was safe to use. I have about 15 bottles, your more than welcome to a couple for free,if you cover postage. Or I could have a run out in the turbo (wheather permitting) Edited by alaskanow0 on 2nd Jun, 2012.

I've been using the Castrol Valvemaster with the octane booster for years. Last time I took the head off there was no evidence of valve recession. |

I think the castrol valvemaster seems the way to go, great value and its available local if needs be.

Another vote for the Castrol here.
