LRP and catalytic-converters

Folks,
I hear that leaded petrol "poisons" catalytic converters.
My questions are
a) would anyone give-a-**** and
b) is LRP safe in a catalyst-equipped motorcycle?

 

No

LRP has tin instead of lead

OK; but what does it "do"?
(i.e. what's the problem with using it?)
Thanks ..... Clem
[or was that covered with answer #1?]

 

My question is why would you want to use LRP anyway. Normal PULP is the
same octane rating and pretty much the same price, it will reduce pinging
the same as LRP might. Concerned about the valves in the BMW? I wouldnt
be, they dont need LRP. besides many petrol stations are now doing away
with LRP and supplying PULP etc in its place anyway, so its getting harder
to get.

I actually find LRP is more expensive than Pulp.

Why would you want to use LRP? As far as I know it's no higher octane than
PULP, it's scarcer and dearer, and your engine isn't designed for it.

In any case, even if you don't care about your catalytic converter, the
whales and orange-bellied parrots will thank you for keeping it in good
working order.

 

Anything that poisons cats is OK by me.

It was a simple case of "No PULP". (Rare these days, I know)

but then they're not safe to eat.

You can use regular unleaded in the beemer in cases of emergencies
Just don't load it up or it will ping.
Remember there is still some pulp inside the tank even when you fill it.
As for LRP
That stuff will wreck the catalytic converter.

Which brings me back to part(a) of my original question: "would anyone
give-a-****"

Am I likely to care or even know if my catalytic converter is wrecked?

Anyone know if this is going to affect the bike's performance? (Curiosity
only; one tankful isn't gonna' do much)
Clem

 

I think what may happen is that the lrp may affect the O2 sensor that
resides in the cat.
Because the stuff in the cat gets wrecked it may affect the true o2
levels that it picks up hence performance problems.
LRP also leaves a reddish deposit on the plugs and may lead to fouling.
Best to remove the cat and get a flow through pipe.
Will also sound shitloads better.

 

The bike/ engine will run fine, no probs there.
But it'll bugger the cat, destroying the "filter elements" from what I
understand, making the cat just a dead weight....which IS a justified
explanation and sound reasoning to the better half to close her eyes in
defeat and let you go ahead with the purchase of the Staintunes you wanted

Shit, worked for me, even though the Strom never came with a cat, don't tell
her though )

My (probably incorrect) understanding is that the lead in leaded fuel
would coat the platinum inside the catalytic converter rendering it
useless. Even though many would say they're next to useless anyway
and supposedly take about 20kms to warm up sufficiently to do their
job. I've no idea what LRP would do since there's no lead in it.

Cheers,
Ash

 

Ha hah; CLASSIC!!
Al Pennykid has a spare stainless system in his shed and even though I
initially refused it my latest trip has made me think it'd be nice to have
a full-sized left pannier and a smidge more "rort" from the pipe wouldn't
go astray either. (I made the mistake of riding my brother's VTR1000 back
from Pakenham Upper [my favourite suburb-name in the world] to Warburton
and a bit of throaty big-twin pipe-rasp is pretty addictive!)
Clem

 

The lead in the fuel might cause carbon deposits to be left in the cat
converter which will disrupt the [free] flow of exhaust gasses through the
exhaust, reducing performance and increasing exhaust and engine temperature.
This may in turn cause the honeycomb material in the cat converter to melt,
causing much greater interruption to the flow of exhaust gasses and eventually
**** your engine. Using LRP once probably won't do much damage.

A friend of mine is doing a doctorate at melb uni on LPG in cars. they also
run the ford motor that they have there on petrol. one day somebody went to
the servo to get some ULP but came back with some LRP. after one tank of the
LRP the motor was so damaged by it they had to rebuild it. that was about 2
years ago. they then did a test on all LRP that were available and found
that only one did not damage the motor. cant remember which one. I am sure
that they have improved LRP by now. IF YOU WANT TO USE IT THEN USE IT. I
would not touch it with a barge pole myself.

ULP is supposed to be about 92 octain
PULP is supposed to be about 94-96 octane
Optimax and others are supposed to be about 98 octane
LRP is supposed to be about 92 octane. it is not the same octane as PULP and
has not been since half lead came in years ago.

Smiley.

 

Any idea what the damage was? I've heard the additive/deposits stories but
the only actual "damage" I've ever heard of was the PULP/tolulene
tax-evasion scandal a few years ago.

96 (the same as PULP)
That's according to www.shell.com.au and www.caltex.com.au

I will ask my friend when i can and get back to you.

 

The tin *replaces* lead in the petrol.
HTH.
