As far as I know, you can change any engine that is supposed to run on 'Super' (Leaded fuel) to be able to run on Unleaded. The issue is the valve seats, which need to be hardened. Engines designed to run on leaded fuel were designed so that the lead provided a sort of 'cushion' (Ok people, I'm simplifing this here) for the valve seats. If you run an engine designed for leaded fuel on unleaded, there is no lubrication for the valve seats, and they get destroyed, leading on to other engine damage.
How much does it cost? I don't know yet. I'll post a new thread about it when I get mine done.
Who can do it? I guess an engine reconditioning specialist would probably be the best bet, but a decent mechanic could probably do it. I think the most important thing would be to get whoever does it to write out exactly what they did, so you have some sort of proof if you run into any problems later (ie you run it on unleaded and have trouble with the valve seats).
Not many people seem to know this, but soon in Australia you WILL NOT be able to buy LRP (Lead Replacement Petrol)
, which replaced LP (Leaded Petrol). It's being phased out, and so soon you will only
be able to buy unleaded, Diesel, LPG (Liquid Petroleum Gas), and the various 'Premium' unleaded fuels (Optimax, Vortex, Synergy, etc.) at your local petrol station...
So if you're going to continue driving cars powered by engines designed to run on leaded fuel, either get used to adding additives to your fuel (such as Valvemaster
, which is what Shell/Coles Express sells and I use), or go and get this done to your engine.
