Question Leaded Fuel

Does anyone know when leaded fuel is due to be phased out? I heard ages ago that it might be later this year but I can't really remember. As for the lead replacement petrols, are they any good? Have people using them had any troubles?

I think leaded petrol IS phased out. Ive been using LRP in a 81 corolla with no hassles at all. Was as gutless as crap still...

To my knowledge leaded fuel is gone and LRP is for pre 86 leaded cars,some owners and mechanics have reported problems with LRP but I think it depends on the engine,whats been done to it and what its used for, I will be rebuiding my Ford jeep engine soon and it will be having hardened valve seats and stainless exhaust valves to cope on unleaded,regards Ford jeepman.

LRP is alright for stock engines. For performance engines, you will have to back the timing off quite a bit to avoid pinging. My friends HZ Monaro will not run on the LRP (but thats with 11:1 compression).

LRP is just another scam to get rid of older vehicles..
It lacks any type of upper cylinder lubricant that works, and
the end result is that valves and seats just die.

Even a standard old Nissan Bluebird had pieces of the piston
crown blown out from pinging, the pits in the piston were
quite surprising when we saw them with the cyl head removed..

Looks like the only alternatives are unleaded conversions, (suggest using premium unleaded if you have a modified engine), or going to LPG. But make sure you use an upper cylinder lubricant with that too!!!

My old XE 351 wagon didn't run on super once they started to muck around with it, but maybe the compression was a tad too high, with the block decked, and running 302 closed chamber heads that had been shaved.... Went great at first though..

Then I discovered the ED XR6.... And then an ED XR8.....
And now I have a house and a $1500 XD.......and no more XR....

I have a few clevo's and none of them like LRP at all , it really does seem crap no matter where you get it. Optimax and some additive seems the price to pay these days for performance.......

But then there is the whole thing with fuel additives and the new legislation that can lead to HUGE fines.

Whats a man to do? GO GAS!!
