Maxol E5

Armin_Tamzarian

Has Maxol's E5 fuel been rolled out to all stations nationwide yet.

maxol.ie only lists a couple of stations around the country as having it this may be out of date.

Is Mitchelstown still the only Maxol station in Cork that's supplying E5?

AugustusMaximus

No, Maxol on the Lower Glanmire road has it.

Is this higher octane fuel much better for your engine ?

AugustusMaximus

Just one pump I think btw. Its the stack nearest the road but facing away from the road if you know what I mean.

BArra

couple of q's

is it higher octane than normal 95 ron? ie. giving better performance from turbo petrol cars?

how much extra does it cost?

finally does any other petrol station franchise sell higher octane stuff, v-power used be here in the shell days but its long gone with the topaz takeover

only other i can think of is texaco techron, but i thought techron was similar to e5 being it has ethanol in it meaning it just helps clean your engine, and is just 95 with additives

Most of the answers are on the Maxol site here: www.maxol.ie

The only question not answered is about other stations. Some posters on here that are in the trade say that other suppliers sell E5 but don't advertise it (they're not required to under EU law).

AFAIK VPower hadn't a higher octane rating.
I think it just contained engine cleaning additives.

I think that the octane level of E5 is around 98/99.

A higher octane level doesn't result in improved the performance as such.
It doesn't boost your power like something like NOS would.
A higher octane rating means that the petrol will have a higher explosion point.
Basically the engine can operate at higher temperatures with a lesser chance of knocking which can lead to engine damage.

I think that higher octane fuels are mainly beneficial to cars that are setup to run on higher octane levels.
My car is setup to run on 100RON so E5 would be a big advantage for me.

As well as Glanmire I've heard that Carrigaline also sell E5.
It appears that the information on maxol.ie is well out of date.

E5 is 99 ron fuel, the higher the octane number the greater a fuels resistance to detonation; therefore it can withstand higher compression, the kind from turbos. You will gain more power from your engine from it, it also burns cooler in the engine, thus increasing performance. It is dyno proven to enhance performance car engines.

I think its normally 2-3cent a litre above your "average" garage's fuel.
V-power was 95 octane. It is the equivalent of Texaco's "Techron" fuel. "Techron" contains no ethanol to boost the octane number.

A point to note about ethanol is that it is less efficient than straight petrol. It therefore requires a little extra to do the same work. Using E5, you will notice a slight rise in fuel consumption.

Most import cars have self learning ECU's that map the engine to the higher octane fuel, (ie up the compression and thus upping power) as the fuel wont knock in the engine. Alot of cars will only notice an improved acceleration using E5 as their ECU's don't map the car to up the compression.

If its one pump then its all pumps, they arent getting special deliveries just for E5, its their standard fuel now, though took longer to roll out to West coast.

The pros and cons of E5 as well as theories that all fuel is already E5 have been discussed to death here already.

Jap cars are mapped for Jap fuel (over 100 RON) so run much better on this stuff than on normal Irish fuel, not sure if there is much of a difference with Euro cars

All the proper Euro's are designed around 98RON, use less and you dont get the quoted paper performance spec.. Oddly (hardly par for the course especially when talking about Turbo'd Jap stuff), the test below shows a Jap import that didnt even achieve its quoted BHP with any fuel including E5 while a German Domestic car gained impressively over the paper spec.

Came across this very informative article done by Thorney Motorsport in the UK (BMW & Vauxhall specialists) on their Dyno Dynamics rolling road:
http://www.thorneymotorsport.co.uk/tuning/Fuel_Test_Results.shtml

Read the pdf version (at the top of the article after you click the link) to see the dyno sheets as the ones in the link are too small.

Note, Shell Optimax has been replaced by Shell V-Power in the UK, which is not the same as the Shell V-Power in Ireland (which is 95RON)

Method of testing (this was not some claim by a glorified internet warrior of testing various grades of fuel in the period of 1 day - Thorney Motorsport spends over 300,000 pounds a year on testing various items):
- each car was run for 3 full tanks of regular 95RON using different fuel stations and filling up at different times of the day
- car was then tested on the Dyno Dynamics rolling road
- process was then repeated for all the different types of fuel grades
- each testing time was chosen at comparable weather conditions
- whole process took 8 months to complete

Cars tested:
1) Toyota MR2 (factory quoted 200ps = 197bhp)
2) BMW M3 E46 CSL (factory quoted 360ps = 355bhp)

Results (all estimated flywheel figures on a Dyno Dynamics rolling road):
1) Toyota MR2
- Tesco 99 = 185.1bhp
- Shell Optimax (now replaced by Shell V-Power) = 182.5bhp (-2.6bhp / 1.4% loss vs Tesco 99)
- BP Ultimate = 180bhp (-5.1bhp / 2.8% loss vs Tesco 99)
- regular 95 RON = 177bhp (-8.1bhp / 4.4% loss vs Tesco 99)

2) BMW M3 E46 CSL
- Tesco 99 = 379.7bhp
- Shell Optimax (now replaced by Shell V-Power) = 369bhp (-10.7bhp / 2.8% loss vs Tesco 99)
- BP Ultimate = 369bhp (-10.7bhp / 2.8% loss vs Tesco 99)
- regular 95 RON = 337bhp (-42.7bhp / 11.2% loss vs Tesco 99)

Afaik Tesco 99 in the UK is E5 too. A 42BHP drop when using 95octane vs 99 is colossal.

The trouble is that there's so much conflicting infromation.
Maxol's website says that E5 is only available at a handful of stations.

I've been told on here that it's now available at more stations that listed.
I'm in Cork on holidays at the minute and was told that Maxol in Carrigaline and in Glanmire are selling E5.
I asked the young fella in the shop in Carrigaline.
He went out back and got the manager who told me that it's called E85.
When I pointed out that E5 is a different thing than E85 she repeated slowly, it's called E-8-5

I've emailed Maxol but haven't received a reply.
If E5 is now the only petrol that Maxol are selling nationwide then it's pretty poor on their part that they haven't updated their site.
I know that lost of modified car owners are keen to use E5, you'd think that Maxol's marketing department would try to capitalise on this.

Which means any M3 owners here are being robbed of power with the general lack of anything better than 95.

Altho if a US spec M3 gets full power on 93, why can't a euro one do it on 95?

It's also a pity that they didn't test E5. My own unscientific right foot reckoned there was more poke in 98 than in E5.

See, this is what I'm talking about.
You claim that E5 is available at all Maxol stations as their standard fuel.
Other posters have claimed that E5 is available in Glanimre and Carrigaline.
Here's the reply I just received from Maxol that claims that at present, Mitchelstown is the only station in the whole of Cork that supplies E5.

It's all as clear as mud.

Hi xxxxx,

Thank you for your email.

At present Mitchelstown is the only station with E5 at present. I will hold your email on file and when this changes I will let you know.

Should you have any further query please do not hesitate to contact me.

Kind regards,

xxxxxxx

I filled up at Maxol last week and the pump I used wasn't labeled E5. From what I could tell, only one pump had the option of regular or E5 and that was the pump I mentioned above.

It was the one pump with an E5 sticker on it and also had a stick saying "Warning, contains bio-fuels".

Bandara

as someone who has petrol stations I can confirm that my own sites only have the option of selling E5, when ordering the fuel I simply order Unleaded and I get E5 regardless. Its the standard now and has been since early last year

I have no signs advertising this and either do practically all other stations as fuel is fuel in the eyes of 99.99% of the public.

I can only speak from experience with 2 of the largest fuel brands in Ireland and confirm that both sell E5 as their bog standard unleaded offering.

That warning is on the E85 pump in my local Maxols.

Sorry, you're right I'd say.

Does anyone sell just petrol in ireland anymore ? without ethanol ?

No one but Maxol advertises Ethanol content, all you get is hearsay on the rest.
Why would you want it without Ethanol blended? This isnt the US with their ****ty low grade fuel cut with high ethanol concentrations to make an "average" quality fuel. 5% Ethanol on 95octane petrol (already reasonably high) gives a solid, 99.2 octane fuel.


PS: Why not make a new thread instead of digging this one up?
PPS: You have just 10 posts spread equally over 6 years... curious!

Not really. Japanese service stations such as Idemitsu Kosan or Cosmo sell regular (95-98 RON) and hi-oku (High Octane - like Cosmo's Magnum 100) but people rarely go for hi-oku as it costs about 10yen (6 cent) a litre more than regular. Most run on 95 these days, it's a recession there too (and has been for 10 years afterall).

L1011

From what I've heard (I've family in the business) the reason that only Maxol and TOP advertise E5 is that they're getting it all from Whitegate refinery where they know its 99.2 octane but the general E5 imported here from other refineries (Whitegate is the only refinery on the island and its peak capacity is less than 30% of ROI needs) is anywhere from 95 to 99 octane depending on the blend they use.

The important thing to remember here is that E5 isn't a specific fuel blend. All it means is that 5% of the volume is ethanol.

It'd be illegal to claim you've got "99 octane" fuel when it could be as low as 95, and Maxol have given people the idea that E5 is 99.2 when its more commonly just 95 in continental Europe, so thats why most stations say nothing. As far as I'm aware ALL 'standard petrol' sold in Ireland has been E5 of varying octane for a while now.

Its entirely legit to sell any grade above 95 as 95 - the rules only disallow selling below stated in octane.

I.

Correct, for at least the past 2 years or so.

E7, B7 and B5 are on the way, I got my tanks all re-certified for it a few months back.

Maxol have been selling B5 in Nordieland for a while now come to think of it...

Any idea of the Octane of the E5? B5/7 I assume are BioDiesel blends, local sourced BioDiesel or import? Will be nice to see a cut down on smoke on the older diesels out there.
