Which additive for E10?
Discussion
Just pondering out loud, so please be kind...
Mrs BrettMRC has a '70's porker that she usually fills up and then adds some lead subsitute additive, (think it's Wynns).
Anyway... given the E5 to E10 changes that are going on, can anyone recommend an additive that will take care of the lead issue and stabilise the fuel in the tank?
Thanks!

Just a heads up that E5 can also cause problems, from rotting fuel lines and certain gaskets, to gumming up fuel lines and carburetters.
Had a small car fire two weeks ago due to a rotting fuel line.
I've been recommended a Millers additive that does both Ethanol fuel balance and lead substitute. Can't recall the name off hand but the recommendation came from a respected source

I've used Tetraboost for years now. It's the only additive that's real tetra-ethyl lead and it also protects against the effects of ethanol. Not the cheapest but I only use 10ml per litre so for the average classic that does few miles it's not a big deal.

I'll make my usual point which is that, when we were first able to buy branded fuel again after the war, many of us found Cleveland Discol suited our engines well. That is to say both pre-war cheapo bangers and modern (1950s/60s) sports cars alike.
Discol's selling point was its ethyl alcohol content which was high by modern standards, nevertheless our fuel consumptions were quite good.
I also have difficulty with some of the urban myths about alcohol attacking fuel system metal, particularly solder. I have a pewter* tankard which I have frequently exposed to ethyl alcohol (in aqueous solution of course) without any effect.

- pewter, like soft solder, was an alloy of lead and tin
"70's porker" = "Neue Klasse" BMW?

One poster states confidently that all M10 engines have steel seats and don't need lead substitute
But the OP there has been informed by the BMW Archive, no less, that his 118 has cast-iron seats.
You could ask the ardhive about your mrs.' car?
It may be that here in the UK we stress overly about lead-less valve seat recession. The Yanks had lead-free years before we did, no one worried and there were no reports of recession. How does Mrs.Brett drive? Is she a hot-shoe, or is it a shopping car? Only long periods of high revs, motorways or competition, are really going to cause any damage.
