ULP into a PULP Vehical?

[Ext User(Mack)]

What's it going to do? Damage? Void warranty? Notice a difference?

Thanks..

It won't void your warranty and it it most likely won't do any damage to the
engine. The car would obviously have a knock sensor and it will retard the
ignition timing for lower octane fuels.

Your car might lose some power and torque and some performance and the fuel
economy might not be as good. But that depends on the car really. Higher
octane fuels such as pulp burn slower and more efficiently. In the end you
might be paying for more fuel running standard unleaded in a car that is
optimised to run on premium unleaded in the end. But it depends on the car.

PULP is a Super ULP.
PULP is used on cars with higher compression that need more "Power per
Bang" :-)

You will notice a lack in power, rattling noises in the top of the motor
and in the long term, some damage.

If you have put ULP in by mistake, keep adding PULP as you use it up.
(which it should do faster than it used PULP).

Why do VW and Renault specify a minimum of 98 and 95 RON, respectively,
for the Golf and Megane that I own.

Not alot

On the rare occasion. Some of the early STI's had a bit of a detonation
issue on the lower octane fuel we have compared to Japan. Most new cars
will have a knock sensor which will prevent this happening too much.

>Void warranty?

Almost impossible for the Manufacturer to tell what fuel you used.

>Notice a difference?

Depends how you drive if you are putting around town or out on the
highway you wont notice it. If you are driving 10/10ths the knock
sensor may get the ecu to stop the detonation usually by dropping
timing advance or adding fuel both will cut the engine power.

Because it doesn't cost *them* anything.

It might ping a bit, and it might lose some power (depending on how
"nervous" the knock sensor is), but it most likely won't do any damage.

Feel free to try it :)

My car requires 95octane minimum and I generally run it either on straight
PULP or a mix of PULP/ULP.

Recently I've been doing a lot more driving and had the chance to compare
straight PULP against straight ULP. In my case the power was noticably (and
I mean significantly) down on full throttle. There was no pinging but the
power was way down.

OK, octane basics....

Octane is a measure of the ability of a fuel to avoid detonation/knocking.
The higher the number the more knock-resistant it is (pick a term:
ping/knock/detonation). For a given design of engine it will need a fuel
that will cover the entire operating parameters without knocking, hence why
a manufacturer recommends certain fuels.

With modern cars the engine management system can do various things to avoid
knocking, the easiest one is to reduce the timing to prevent it occurring
(which also reduces power). So, it's not always clear what a modern car will
do on low octane fuel other than lose some peak power. Most will do their
best to avoid pinging as this can harm the engine.

Using a fuel with a higher octane than recommended does nothing for power,
unless the engine management can adjust for it. Even then there is a limit
as to how much the engine management can adjust to take advantage of it.
Very few cars can make use of octane ratings above the manufacturers
recommendation (which the fuel adds never mention).

To answer your questions:

1. It depends on how much lower the octane rating is and how close to car is
to it's normal octane limit. You may notice a loss in power and you may hear
pinging at high engine speeds/loads. Pinging is not good so, if you hear it
back off.

2. Damage is unlikely in the short term but long term pinging isn't good for
the engine.

3. It could void warranty. I'm certain that a dealer would reject an engine
warranty claim if you told them you used lower grade fuel than they
recommended.

4. Some engines are more sensitive to octane, my car definitely has less
power. A lot of it will depend on your driving, noting that high
loads/speeds are where octane limits will show up. If you bumble along the
road like half of the zombie Camry drivers you would never notice (but then
they wouldn't notice being run over by a truck either...).

PS. If you decide to try different octanes on a modern engine give the car
some time to adjust before making any judgements.

I can't think of a vehicle these days that wouldn't have a knock sensor, and
especially one that's tuned to run on high quality fuel.

It would be a pretty brave/stupid manufacturer who released one that didn't.

How about the other way around?

I have a car using ULP, what will happen if I fill with PULP or UPULP? What benefit I will get by paying extra?

Thanks guys

If its a reasonably late model car with a computerised engine management
system, it will gradually retune itself (typically over a couple of tanks)
to use a higher compression ratio and thus achieve slightly higher
efficiency. There is no consensus on whether this compensates for the higher
cost.

If it needs to be manually retuned, them the aggro and lesser potential
gains make it infeasible.

I got about 10% better fuel economy running it in one car, so it was
actually cheaper to fill up with 98 RON PULP if regular unleaded was
92cpl or more.

It's 2006 car..

Should I need to goto mechanics to change the knock sensor or just fill up the car with PULP?

Thanks

THE new VE require PULP to get the best out of it. holden just chose
to say it needs ULP for the plebs.

and dont forget that some PULP is actually E5 or greater ethanol. If
you ahve an older Nissan you may end-up with stuffed fuel lines.

Thats only for the v8 models besides that I put PULP in my Camry and Dan
puts PULP in his Calais and Rodeo, and we notice the cars runs smoother and
does not need to drink as much with this type of fuel. And before you go on
saying but the Camry does not need PULP I know that but with regular
unleaded it does not run as crisp as it does with PULP.
