Difference between miles and miles plus fuel

mayo51

Apologies if I have this post in the wrong section.
I am traveling to Dublin tomorrow and last time I was there I noticed there is a miles plus fuel which is higher cost per liter. Would it be a good idea to put in a tank of This stuff or is at really worth it?

As per the two threads that Biko had referred to, I am a big advocate of milesplus diesel.

However, I recently switched back to regular miles diesel, and didn't initially notice a difference.
However after 4 or 5 tanks of the regular, I've noticed that my mpg's have dropped slightly, and that the engine is a little noisier.

I have about 120L of miles diesel yet to use (in 5 gal drums) , and once that is used up, I'll be switching back to the milesPlus.

I have that much diesel, as one of the local Circle K's that is usually cheaper for fuel, had the 10¢ off offer, and I combined that with 4¢ off with my 2 fuel cards to buy 200L of milesdiesel for €1.18/l

I had previously been running the car on another 200L batch that I bought with the same offer from another Circle K.

I haven't used Applegreen, as my local AppleG seems to have guys out on a very very regular basis doing work on their storage tanks, and my neighbor had issues with fuel he bought there, and ultimately got a cheque (and a non disclosure form) to compensate him for the issue he experienced.


The long and the short..

Long term useage seems to have benifits, but the odd once off fill of plus fuel won't give any immediate noticeable results.

The internet is overflowing with this type of opinion based on individuals driving their cars on different fills, everyone appears to be an expert but none of them have any actual evidence to back up their claims, none of it is proof of anything.

True

I'm just giving my experience.

I was recently in a KIA garage waiting to pick up a friend, while I wandered about the showroom, I opened the fuel cap of a car.. a Kia something?. Inside it said 91ron or 87aki (us octane)

You can't buy 91ron in Europe anymore.. so I doubt any super dooper petrol will do anything for an engine designed to run on the lowest (im)possible to buy petrol.

Edit.

Actually, a study on the cetane vale of diesel fuel and the improvement in power that I read showed that higher cetane values provided more power and better fuel economy. (I'll try and find the link)

Topaz told me via DM that their plus diesel has on average 3 more cetane points/numbers

OP, you would possible get the same benefits from throwing a bottle of fuel system cleaner into the tank once a quarter.

I can't find the link to the study.. it was fairly comprehensive.. and it was downloaded on my previous phone.

It went into lots of boring detail.

But here's a different reference.. a lot shorter

Possibly..

I used to use 2-ehn to improve diesel, and I felt that it worked, however it does deteriorat when opened, so by the time I got to the end of the bottle, it was probably flat.

As for fuel system cleaners.. I think BG244 and BG44k are highly rated.. not cheap

Edit.

I think this is the link to the pdf of the study I mentioned.

The thing is even if there is some benefit to them is it anywhere near the improvement in MPG needed to cover the cost?

You Suggested you needed 4-5 fills before noticing any improvement, that's €20 or more plus extra cost every subsequent fill, can you really say that it provides anywhere near the benefit that you are paying for?

I found the engine to be quieter, a little more responsive and slightly better mpg.

I'll be switching back to it.

But I do realise, and so do the fuel companies that premium fuels only account for 4.7% of sales (I'm referring to UK sales of 95ron Vs 97/98/99ron)

See pg 62

Funny you should mention that! ^ I have been told that some cars you should not add any over the counter additives of any sort! I have a gtd and in my owners manual it says that if I want one vw sells them in the dealerships. Could be just vw trying to promote themselves! I have used a bit of red ex before knowing this info. My mechanic reckons it’s ok and I felt the car ran quite well after a drop of it! Although I am an old fashioned type of guy where you get what you put into something so if you look after your car with high quality fuel you will get high quality service back from it 😉

I agree.. however, the majority of boardsies, just want to know if Dipetane will get them to pass the smoke test at the NCT.

There's no time in this world (boards.ie) for us old fashioned types

Right lads I have some results! I travelled to Dublin via the m17, m18 and the m7 and travelled back to mayo via the M4. A total round journey of 410 miles. Filled my car up before I left. Usually I would get 450 miles per tank but I have 410 miles down and still have a third of a tank left with my clock saying I have another 170 miles left in the tank. The driving was fairly standard. Driving the speed limit without going over. Lots of driving against the wind. So I put a shot of red ex in during my last fill. I now appear to be getting more miles per tank. I am a great believer in facts and the facts say I am getting a few extra miles per tank. Although I didn’t fill up on milesplus yet as I had half a tank of regular miles diesel in it.

They say nothing of the sort. Not until you use the brim method on both will you even come close to being able to accurately compare the two.

Absolutely. The driving conditions were nothing similar to what I normally drive in. I’m just pointing out a fact I noticed about the car. I agree though the Brim method on two identical runs in identical driving conditions can a complete accurate result be established! What I mean about the facts is that the fact is my car is getting a few extra miles per tank! I’m not sure whether it was Redex or not.

I get ye dude.

paddyjoe183

I've tried both now and can't see any difference between the two apart from the cost of the plus been more expensive.

Anyone else notice a difference?

Thanks

Ohh sorry

I was getting 4 cent off miles plus diesel for a few weeks.

I always record my mpg.

Zero difference

Thanks, I thought it was just me 😊 I'll save my money and stick with cheaper

Merged with another current miles plus thread

mayo51

So lads. I put in a tank of miles plus diesel from bottom to top. I am definitely getting more miles from it. Maybe it’s just a psychological thing but I usually reset my clock when I fill up and I always get 400-450 bottom to fill depending on driving style. It never varies outside this zone. When I filled up with miles plus I found I was getting 460 and the diesel light was just coming on. In relation to power I found no extra addition. Granted I know weather, driving style, use of clutch, wind etc can play a part in this but I still reckon I am getting a few extra miles!

I can't find it on the .ie site , but some of the foreign CircleK sites state that best results are after 3 to 5 tanks.

I'm back running regular miles for the past 400L , and I'll be switching back to plus in the coming weeks.

You would want to be seeing at LEAST 7% improvement to justify the cost (if you're paying full price). Also depends on the current diesel cost (currently 1.39 for me)

Actually 5%

1.399 + 5% = 1.469. That's 7¢

Well, I've had positive experiences with the Miles Plus fuel. Two years ago, I ran a Fiat Ducato (ya, a van!) on a mix of Shell V-Power Racing Diesel and BP Ultimate Diesel for about 2500km over a month (holidays in Germany). The Ducato ran like a champ on a diet of decent diesel.

After coming home and after going through about 3 tanks of normal Irish diesel, one day when joining a motorway, I noticed that the van could not accelerate the same way as it did when joining the autobahns a few months earlier. That's a tough test as you are trying to get a fairly loaded van up to motorway speed before the end of the slip road, so it's always foot to the floor and loads of revs. The difference was so noticeable that I booked the van in to be looked over.

Before I took the van in, I ran it for a few tanks of Miles Plus diesel and it ran much better. The acceleration was almost back to where it was on a diet of German diesel. Since then, I only run the Ducato on Miles Plus diesel at home, standard diesel in France (it's rare enough to get anything else besides standard Gazole) or high Cetane Diesel in Germany.

Ya it's a bit more expensive but I don't mind as It's easy to notice the difference when you are trying to haul 3.3 tonnes up to motorway speed.

TL/DR it works for others besides Cars!

But that's just anecdotal ..people on here want hard facts to disprove there own anecdotal evidence that the plus fuel does nothing.

Despite links being posted, stating the
benifits of higher cetane diesel.

Normally, sitting in town traffic I use well over half a tank. Filled up the last 2 tikes and noticed last week there was still half a tank left. So it seems that the engine runs better when idling aswell (sitting an hour each way in traffic). Plus, my car is meant to run on 98 octane
