Its not unleaded unless he's put the unleaded engine in the car.yeah right said:No - it's just there's some clown trying to sell a '82 XE Ghia that I'm sort of interested in - but he claims it's an unleaded engeine - but everything I've dug up on it points to the opposite. Identicar publication makes no mention of any changeover any year on the XE's - but it does mention the XF's in '85. Just wondering if there were any special cases - he claims to have run it on unleaded and that it's the original engine - can't see that being true.
Luckily we don't have all that emissions rubbish here in NZ - we have different rubbish....xdc351 said:Its not unleaded unless he's put the unleaded engine in the car.
There were absoloutly no unleaded falcons built in '82.
And if he has put a later unleaded engine in there, see if it has a cat and a small neck fuel filler (there are other things but these are the most obvious), if not is illigal and you run the risk of being defected and fined by the EPA by running unleaded through there.
The cost is not worth it in my opinion. Better off running ULP and saving the cash for hardened seats......or better still, and xf unleaded head from wreckers.XF__UTE said:Run BP Ultimate with flashlube or valvesaver. You get higher octane and better milage. Ultimate also flushes a lot of the carbon out of your engine. Costs more, but your car will run heaps better.
Yes, but there are different levels of hardness, and manufacturers usually do not specify a higher quality material than they have to (costs more money). It's different with a lot of other cars that were also sold in the US (which had unleaded since the 70's) like most Japanese cars and also a lot of the Europeans but of course this was not the case with the Falcon.ir33t said:all aloy heads have hardened valves seats.
ULP is fine to run in an aloyhead.

Yes they will run ULP and LPG for the most part, but it will eventually destroy the head, my first engine had this exact problem ('82 XE). It was dual fuel but the previous owner never ran petrol through it, even the fuel in the tank was stale, and the head was stuffed. The conversion was done in 1993, I got the car in '98 if that gives you an idea of how quickly they can be killed.
2 tanks of premium to 1 tank LRP or premium/additive should be fine.
