High quality petrol?

mel.b

Are there any chains of petrol stations selling a high quality petrol? I'm having trouble with my car at the moment, the mechanics know there is a problem (have been able to replicate it) but they can't work out what the problem is. The air flow meter has already been replaced which made no difference and they suspect it may be the EGR valve, even though it looks fine and no error is coming up. I'm looking at the region of €500 for a gamble to see if replacing that will fix the problem. Someone suggested to me to get a couple of fills of good, high quality petrol to see if that makes a difference. I know in Australia you can get different types of fuel, but I haven't seen any stations around me with anything other than standard unleaded and diesel. So are any stations selling premium unleaded (or similar)?

There are no garages selling super unleaded, youncan get it up north.

Why not try some good octane boost in it, NF octane boost or millers cvh are supposed to be good.
What car is it btw?

It's a Honda Fit (Jazz) 2006 Automatic. It is having a brief loss of power or jerk at around 2000 revs when accelerating at low speeds (such as out of a roundabout or intersection). No problem when cruising.

So long as your filling up in known brand stations you're already topping up with high quality petrol. I don't think an octane booster is going to solve your problems...

Might be better getting a quality mechanic who can diagnose the problem properly.

It has been into two mechanics now. One is very good and it came up with a fault on their machine, however because the car is an import, the error was in Japanese. They managed to work out it was related to air flow and changed the air flow meter with no improvement, so looked at the EGR which also was ok. They suggested going to the Honda dealer and to hook it up to the Honda diagnostic system which was done today and it didn't come up with any fault. Their mechanic also looked at the EGR and said it was fine, however he thinks that still may be the problem even though it looks fine. So not really sure where to go from here.

Throw some diptane in the tank and give it an Italian tune up.

It came up with a Japanese error code?

That's a new one to me.
Genuine question, was he using a Japanese imported obd reader?

Personally, I can't stand EGR's, an internal combustion engine runs better with cold, clean air, not hot and dirty exhaust gases mixed in! See if you can get a EGR blanking plate of some sort!

I use a cheap ass obd2 reader on my 1998 jap import with a phone app. Car doesnt even have obd2 it has something between obd1 and 2 known as JOBD or something to that effect.

Either way, errors are based on a numerical code - not a language., i fear the mechanic may not be diagnosing properly, and/or talking brown..

The difference between standard/regular and premium petrol is the octane rating, which has nothing to do with the quality of the petrol.

That is what I was told. I don't know what sort of reader he used.

But would the code come out in Japanese numbers? Given that two mechanics now, connected up to two different computers have been unable to determine the problem I don't think he was having me on. He also didn't charge me for the air flow meter after changing it and it making no difference so i believe he is being genuine.

Not in petrol engines! Blanking the EGR can result in lean mixture and knocking.

Topaz are spending € 6 million showing off their newer shinier fuel

https://www.topaz.ie/about-us/news-and-media/2017/Topaz-to-invest-%E2%82%AC6-million-in-fuel-launch,-miles.aspx


Petrol here is often pi$$ - grand for cement mixers, shows up in slightly highly strung engines that would be "expecting" nice petrol

More to it that just octane rating

Is the problem more prevalent when the engine is cold or does it happen at any time?

I'm no mechanic but had something similar with auto bmw. Flummoxed bmw dealer who wanted to replace (and charge) items bit by bit til issue was found as diagnostics just showed general problem with engine.

Indo dealer took it for a few days and replaced different parts temporarily til he found the issue - ended up being the high pressure fuel pump.

It is intermittant, in that it happens every day, but not every time I am accelerating. At a guess I'd say it is slightly worse when it the engine is warm. I drove from Dublin to Ennis the other day, stopping in Limerick for half an hour. The drive Dublin to Limerick was pretty ok, but Limerick to Ennis was shocking. Saying that however, yesterday I had only driven the car a couple of kms and it was really bad, jerking a few times in a row after turning out from an intersection.

The quality here may or may not be bad, but the octane rating has absolutely nothing to do with it.

Ok, then probably not the fuel pump.

Maybe look for a specialist independent and see if there are specific honda forums. Www.clubjazz.org comes up on Google as one.

You usually find mechanics on specialist forums who will have an idea of the issue.

This the issue? http://clubjazz.org/forum/index.php?topic=9100.0

Thankyou!! I hadn't come across the clubjazz forum (had found a few others), and a quick scroll through that has found some posts describing the exact problem, so hopefully now I can get an answer... and more importantly the problem fixed!

If you try the following it might help. Disconnect your battery for 15-30 minutes and then reconnect. Make sure you have radio code if needed as you may be asked for this after reconnecting your battery.

I had a similar problem with another make of car, would loose power going around roundabout and progressed to loosing power while driving along. Mechanic put it on the computer and did not show anything, but made suggestions as to what it might be. The best suggestion from the mechanic was that it may be fuel pump related. He suggested to keep the car full of fuel and see if this helped.

Car forums were full of people with a similar problem to mine, and garages just seemed to be changing items hoping to get lucky. I could not justify changing parts on the car I had, so I decide to try disconnecting and reconnecting the battery even though it was not suggested anywhere on the internet for the problem I was experiencing. However it did seem to fix other car problems, so I had nothing to loose.

Disconnecting the battery worked for me, and there is a chance it may work for you also. If this helps can you report back.

Thanks for the suggestion. I actually had a new battery put in at the end of March. The problem was there before that and still there afterwards. I am assuming that replacing the battery would have the same effect as disconnecting and reconnecting the battery?

Strong rumours that the Miles rollout will be shortly followed by premium unleaded and diesel products in Topaz forecourts before the end of 2017.

Yes putting in a new battery would have the same effect. Best of luck finding the problem.

You won't see milesPlus until after Topaz is renamed to Circle K

colm_mcm

Are all 8 sprk plugs ok? Don't these Fits have the twin spark setup?

Coil packs are a common enough fail on these too.

I haven't heard of a timeline for rebranding since around the time of acquisition, but it was only in the last 2/3 weeks that I got word of the new products coming. Could easily be combined with a rebranding, but the new products def seem to be planned before end of year

miles fuels will be rolled out, with the red pumps.
Then the Circle K brand will be rolled out, along with their 'simply great coffee'.
Then premium fuels will start appearing.

Topaz are currently upgrading fuel pumps in some of its company owned stations to have 4 fuel nossles rather than the current 2.

These stations with the upgrades will be the first the offer milesplus fuel.
