More people using Regular gas in their cars since the price increase on Super

[rspann]

You are correct , that was the vehicle. When I started to use diesel in it it had low power. Eventually I found the problem to be a washer they put in the pump to drop the pressure. Once it was removed the fuel pressure rose and the performance returned to normal.

Get ur regular here ....these stations have it lol

Isn't it banned cuz it has Lead?.

[kamakazi]

We don't sell leaded fuel anymore... At least to the public... So regular, super and premium are all unleaded.
Avgas still has lead... Would like to get some to test

[baby hulk]

Can regular gas exist without lead?

[hydroep]

Ah hear some taxi men talking about using camphor to boost octane...men getting desperate...

Most times in the US they have 3 gas grades at the pump and the cheapest is 87 octane and most people fill up with that.

Even the fuel blends can be different country to country. 87 in the US is the same(?) as 91 RON in Trinidad. Very confusing sometimes.

What about people who mix diesel with pitch-oil? 50% each?

Excerpt From The Economist:

...Another key additive that blenders stir into their brew is ethanol. That is done these days primarily to boost the fuel’s octane rating. A higher octane rating allows an engine to use a compression ratio of, say, 12-to-one instead of a more usual ten-to-one. The greater the compression, the higher the temperature within the combustion chamber. And the higher the temperature, the greater the thermal efficiency and power produced. In a nutshell, high-compression engines designed for performance need high-octane petrol.

Though ethanol has less energy per gallon than petrol, it has a considerably higher research octane number (RON)—around 108 to premium’s 97. It should be noted that this is not the octane rating seen on the pump in America. The RON figure results from a laboratory test done using a special engine with a variable compression ratio.

In the fuel test, the compression is raised until the engine begins to “knock”—ie, the fuel in the cylinder ceases to burn smoothly and instead detonates before it can be ignited by the spark plug. The cylinder pressure at which this occurs is then compared with that achieved while the engine is running on a reference fuel (a mixture of iso-octane and n-heptane). The ratio of the two pressures provides the RON of the fuel in question.

A better way of measuring a fuel’s ability to resist knocking under load is the so-called motor octane number (MON) test. This uses a similar test engine, but with a preheated fuel mixture, a higher engine speed and variable ignition timing. Because it uses more real-world conditions, the MON rating is typically eight to ten points lower than the equivalent RON figure.

In Europe, the octane rating on the pump is simply the RON figure. America, by contrast, uses the average of the RON and the MON figures, called the AKI (anti-knock index). Thus, 97 octane “super unleaded” in Britain is roughly equivalent to 91 octane premium in the United States.

Whatever the test, the point is that knocking needs to be avoided at all cost. If allowed to continue, it can quickly cause an engine to disintegrate. That is because when the air-fuel mixture in the cylinder detonates spontaneously before reaching the top of its compression stroke, the rising piston confronts a wall of rapidly expanding gases from the explosion, which attempt to force the piston back down the cylinder. The stresses caused by suddenly trying to reverse the rotation of the engine can become high enough to shatter the pistons, connecting rods and parts of the crankshaft.

To prevent that happening, a high-compression engine uses a blend of hydrocarbons that is somewhat less combustible than normal. Ethanol has an auto-ignition temperature of 362ºC, while petrol bursts into flames without a spark between 246ºC and 280ºC, depending on the blend. Therefore, adding a little ethanol to petrol can raise the auto-ignition temperature enough to prevent the blend from igniting purely from the heat generated during compression.

On the face of it, then, a motorist would seem ill-advised to use regular petrol in a car with a high-compression engine. That was certainly the case in the past. But cars today have sensors that listen carefully for the knocking sound, and instantly retard the ignition system when they detect that detonation is about to happen.

The delay in delivering the retarded spark allows the piston to start moving downward on its expansion stroke before the ignition actually occurs. That provides additional room in the cylinder head for the gases to expand and thereby reduce their damaging peak pressure—and so burn in a more controlled manner.

To sum up, if the car’s handbook says that premium petrol is “recommended” (rather than insisting it is “required”), then the engine will automatically adjust itself to run smoothly on a lower octane fuel. Because of the retarded ignition, the engine will, of course, produce less power, and have slightly higher fuel consumption. But the poorer fuel economy is likely to be outweighed by the savings at the pump....

$2/l for pitch oil, eh fadda.
i do $40 diesel, and $40 pitch oil mix.

I did as well, on the car that should have been using premium in the first place

i paid $1.50 / liter for pitch oil.... which gas station u going to making u to pay $2/l for that.?
imbert raise the price of pitch oil down by you oar....

Will government still import regular gas after petrotrin is shut down?

Fishermen use it in their boat, so hopefully

If not, seafood price gonna double easy

Just as I said before...if men start using diesel to fish...carite and king fish would be priced more than deer and lappe

[Pointman-IA]

They can import the carite, king fish and ALL ALL ALL just like other products.

[pugboy]

You got it , plus two companies to do it.

@ unipet Santa flora they removed all the super pumps. Only regular and premium. Attendant said is what people asking for. Don’t be surprised to see more black pumps in gas stations now

Regular and super. No premium, owner daughter and the girl behind the counter said that.

where u get that price?

i was jokin inno bro....i srsly thought u knew the price of pitch oil was $1.50
i buy pitch oil in endeavor medford gas staton - by tracmac there nuh - Massey cat-
$1.50 /liter its the pump wit the blue handle -

bought 10 liters yesterday cause my dad wanted it for some odd thing....

if u want lemme kno..i hav a 10 liter container....i go bring it down as far as sando for u...
