If you only run about town in your Mini then it's probably fine for a while on unleaded. But if you use motorways then you must use an additive. Castrol Valvemaster Plus seems to be the one to use.

Even LRP petrol was pretty useless on mtorway runs. I had exhaust valve problems within 1000 motorway miles. Compared to no problems at all using the same engine with a replacement leaded head running on unleaded petrol and valvemaster plus.

Undoubtedly thee devices have a benefit over using unleaded with no addatives.

No they don't, it is the same as using unleaded with no additive. And as for being anyone's guess, there's no guessing involved. It's not just 'some lead' that gets put into petrol which will wash off the surface of a chunk of lead as the petrol flows over it. It's a very specific compound (Tatra-Ethyl Lead) at exactly the correct doseage. There's been lots and lots of testing done over the years, devices which claim to infinitely add lead to your fuel don't work. It's a con.

LRP is the only completely unregulated fuel in the country. There is no standard for it to meet and it really could be anything in there, usually it's junk. No good for protecting your engine and not a lot of good for running it either.

Real 4 star is still available from a select few outlets. It is produced in small batches by Bayford fuels, check their website to find out where you can buy some.
