Hi All . This may have been covered before ,but.... I'm using unleaded fuel and an additve in my' leaded 'ford powered Locost . Is it ok to use LRP when I can obtain it ? I recall reading somewhere that they shouldnt be mixed? Cheers ROD
Someone claimed that LRP was what damages plastic tanks. I like you use an additive most of the time, but have used LRP when not forgotten/not had any
additive. I'm using Millers VSP and have found it very good.
Cheers
You shouldn't mix different types of LRP as they use different additives to replace the lead, either potassium, manganese, phosphorous or sodium
so it's best to stick to one type to avoid chemical incompatibility. Leaded petrol is still available in some places from a firm called Bayford.

So generally its best to stick to either a) additive continuously OR b) LRP continuously? ROD
Also its ben siad elsewhere not to chop and change your additive,as they too can have different properties.
wouldn't it be more convenient to have your valve seats replaced so you can run unleaded?
Apologies if I'm missing something.
Cheers.
Chris.
Hey Chris! I'm missing something too! ie the money to do it ! I worked out (not taking into account of course the hassle factor of adding the additive each fill up) ,that with my current petrol usage it would take about 8 yrs top re-coup the money!lol Rgds ROD
A point that is more than fair.
Is your "ford power" a pinto?
If it is you could get an injection head which is an unleaded head as standard they range in price from free to about £30.
From any injected Sierra or Granada.
Cheers
Chris
Ps if it's a zetec they're unleaded too if it's a cross flow yo could get it converted for about £150
wish i could find an inj head between free and £30,wish i could find a head..
Mines an 1100 escort . Built ,apparently to keep the insurance down for the lad who owned it previous.
Is upgrading to a newer and/or bigger engine an option?
Chris you seem to be missing the point...

Calm down now!!!! lol (we dont want another Wishbone debate! )
someone said it before, just stick to 1. once you are using additive, no point in changing back to lrp when you can find it, just in case it's a different chemistry.

Leaded four star petrol was withdrawn from sale in 2000. Now it looks as if the product that replaced it will go the same way.
Lead replacement petrol (LRP) is essentially a 97-octane (super) unleaded petrol with an additive to give the valve seat protection that some cars need.
LRP now (mid 2002) accounts for only 2.7% of total fuel sales, and forecourt managers will increasingly be tempted to switch pumps to more profitable products.
Trends indicate that you won't be able to find LRP from the end of 2003 except at a few specialist outlets hoping to keep something no-one else has.

We can't say that valve seat recession can't happen with these additives because of the enormous range of engines out there in conditions ranging from pristine to near collapse.
In normal or moderately hard road use however, the valve seat protection afforded by these additives is perfectly satisfactory, and engine life will be just as good as with leaded petrol.
