Which brand of 91 octane do you use? Additives put into the fuel by the petrol retailers if any?

I use BP or Caltex 91 octane almost all the time. I found that when I used BP or Caltex I wasn't having to use a fuel injector cleaner every few months.

Anyone know if the fuel companies really do put their own additives in 100% of the time or is this skipped sometimes?

Which brand has the best additives?

From what I have read these additives are put into the tankers at the bulk distribution depots. In Britain, from what I have read, the cheaper fuel from supermarkets etc may not have any additives & really is lower quality than the name brands. It seems to be harder to find any information about this re. NZ, so any comments would be welcome!

Fuel injector cleaners are a scam and you saying you have to use them every few months is absolutely mad

No one should be using any additives in fuel and these are not reccomend by car manufacturers

Throwing your money away!

The cheaper fuel from supermarkets 100% has the additives in the fuel it's 100% the same fuel from all the main fuel suppliers

I use whatever gaspy says is cheapest near(ish) to me... Have had my current car for 10 years now and had zero problem.

(EDIT: though I do use 95 as recommended by car manufacturer not 91... sorry.)

I believe the higher octane fuels have more detergents. But all fuels have some detergent. But i can't tell you what they are or whether they are any good.

The major brands all advertise additives under their own formulation names. It's either the same thing branded differently or they are the source of the "rubbish".

Examples

"Z91 Unleaded is a quality product developed with our international partnerships and utilises the new additive package we have sourced for Z petrol."

Mobil. "Synergy Extra, our improved fuel with more additive, that helps to improve fuel economy."

Diesel fuel has more detergent

Higher octane fuel is taken out at different stage of the refining process

Injector cleaner is another work for blinker fluid or snakes oil....
You replace your injectors when they are unevenly squirting or not working.. No snakes oil in a can will fix that, if a few thousand PSI and petrol already going through them wont clean them I have no clue what would..........

I know what is in the fuel and it's very much the same thing with different wording

I find it absolutely amazing that someone thinks they need to add fuel injector cleaner every few months!

Car manufacturers warn of not using oil and fuel additives including fuel injector cleaners as the damage they can cause

Detergent in fuel is very important I believe. Hence you don't need to use extra. Detergent is especially important in direct injected fuel systems. CAn't remember the reason .... so maybe I'm talking rubbish

@Batman detergent is used in diesel fuel due to the fuel been a dirty burning fuel and diesel is also a lubricant

detergent you would not use in normal fuel such as petrol as it would wash the bore dry of oil and totally wreck the engine

@Amiga500 Before you waste more money go over to YouTube and search " John Cadogan " and watch some of his videos about fuel and additives

He is brutally honest and to the point and is backed up by experts / scientists

The N.Z. oil refinery is partly owned by the big oil companies (Caltex, BP, Mobil), and all of the fuel that comes out of it has the exact same additives - because it is the exact same fuel. Can't speak for any imported fuel but any fuel made in NZ, no matter where you buy it from, is the same. Any talk of different additives for different brands is just marketing garbage.
