If it's injection it should be run on unleaded. Leaded fuel will foul the injectors.

Yep, as that'll be what it was designed to run on

It depends on the year of the car, not the fuel system type. Think about it... the XR3i came out before the introduction of unleaded fuel in the UK If its post 1989 it will run unleaded no problem, there is an octane"coding" plug near the fusebox (iirc) that can be swapped to map for either 95 or 97 octane. Pre 1989 cars will run on unleaded, but may suffer valve seat wear, accelerated kitten death, end of civilization etc.

Sorry, I was being a bit thick there! I thought unleaded fuel was introduced a lot earlier.

B reg is 1984/5 so "strictly" it needs leaded, but the usual advice is retard the timing to stop it pinking (prob already done by now) and run on unleaded. Also, given the CVH having a tendency to be a bit soft, is it the original engine? It might be a later (and unleaded safe) lump already. The two letter prefix from the engine number will say for sure.

That'd be '84-'85 then. I seem to remember all MkIV Escorts proudly displaying stickers in the back windows proclaiming that they could now use unleaded. All Fords of a similar vintage, in fact. You could either use a lead replacement, just run it and not worry about it too much, or get a later unleaded-friendly head easily enough; Ford made the CVH right up until, what, the mid-90s in the MkV Escort? Yeah, what Scary said. He knows about these things

1989 Peugeot 205. You know, the one that was parked in a ditch on the campsite at RRG'17... the glass is always full. but the ratio of air to water may vary.

To quote Pumaracing:
No point in worrying though, just fill it with unleaded and don't worry about it. If it isn't capable of running unleaded, you can either get hardened seats fitted now or in a couple of years when it becomes a problem, which it probably won't.

^^^ what he says. Our Mini should run on leaded, but we've been filling it with unleaded for the past 20,000 miles with no issues, though it does have an in-line 'fuel saver' so maybe all we've actually done is prove that the magic fuel catalyst things actually work?

Just as long as everyone avoids LRP! The only time I've seen valve recession become a problem on an 'old' head is when you're doing high mileages and sitting at high RPM for prolonged periods (i.e. doing a 60 mile motorway commute at 4000RPMs each day).

I'd run it on unleaded. Bear in mind I run my 42 year Amazon on 97RON, and it's fine. It was actually designed to run on 102 octane leaded, so I sometimes bung 99 OMG LOL ULTIMATE in and watch the bemused expression of the staff on the forecourt.

I get the odd "he's got the wrong pump" look whilst pumping supermegaplus unleaded into the old beast too...

My old fella had a 1987 1300 Kent engined Scrote back in the 90s, which he ran on unleaded and proceeded to tow a caravan with(!) and he burned a valve out on that. Riding on an AA lorry was exciting when I was 12, now it's just tiresome...

Iron headed cars are more forgiving of unleaded than alloy headed cars, yours is alloy headed CVH Engines: Those built up to 12/84 may only be run on unleaded fuel if ‘LPG’ is stamped on the boss of the head above No 1 exhaust port. From 10/85, all engines produced are suitable for running on unleaded fuel.

Don't like stretched tyres, very low profile tyres & I think a car CAN be too low. Perhaps I'm odd.

If it's injection it should be run on unleaded. Leaded fuel will foul the injectors. Eh? What on earth makes you think that? Anyway, just go to Tesco/Morisons/etc and use the cheapest stuff you can get. It all burns. If it bothers you bung some lead substitute additive in if you're gonna go down the motorway. I've run old cars on unleaded for years without issue. Mind you, they weren't Fords

Mk4 escorts with the CVH engine were designed for unleaded. Mine is an 88 1.4 CVH and it still has the unleaded sticker in the window. Also in the owners manual.

If you're worried about valve seat recession you could always stick a tankfull of good old leaded petrol in every once in a while to restore the "lead memory" in the valve seats. There should be at least one garage that sells leaded petrol in your area - you'll pay a premium for it but it is still available! And you can take a trip down memory lane inhaling that distinctive four star exhaust smell! ;D
I'm not sure how much protection restoring lead memory gives, I just remember reading something about it when everyone was crapping bricks about the forthcoming ban of leaded.
