New driver. Best fuel for Honda Jazz EX?

[Westy36]

The time old supermarket vs branded fuel debate. Must make up at least 5% of world wide forum content! 

Every time I stump up for branded, I convince myself of the benefits. Everytime I stick supermarket fuel in, I convince myself it's just petrol in a basic car. Who knows for sure.

When Mrs W had an Octavia VRS 2.0 turbo (Golf GTi), that lived on an exclusive diet of Shell V-Power. The forum traffic highlighted that it was the only choice. So I guess if you have a performance car, use the best. If you've a normal motor, don't stress it.

Obviously I’m talking diesel here, but have no reason to think petrol would be any different, but I guess someone will disagree?

Of course, we all know diesel is exactly the same as a petrol engine...

Which? Magazine did a write up about this, follow link:

I recently saw an elderly couple, on  foot , putting petrol into a can . They had no idea what they were doing, and had probably never actually owned a car , but getting fuel for a new lawnmower etc.   They left the fuel nozzle laying on the ground. 

So as the OP may be completely new to actually buying petrol please excuse my stating the obvious.  Make absolutely sure that you are buying petrol, not Diesel. Using the wrong grade of petrol will cost you more but its not a disaster.  But if you realise you have put some diesel in by mistake do not drive the car. The fuel tank will need to be drained.   

Different petrol companies have their own names for the various grades. With even the cheapest one hyped up by being called 'super extra' or some such. , with more expensive grades having another fancy name, Its  not always obvious which is the  better.     And E10 'sounds' better than E5 Because its a bigger number, but its not..  And not all pumps help you out by displaying the price until you select a nozzle ..

But as others have said  E10 from any supplier meets the specification for the car.     Just look for the nozzle with an E10 sticker.

Since the ISSA brothers took over ASDA supermarket fuel isn't that cheap anymore, they've made some arrangement so that the other supermarkets raised their prices as well which is being examined by the Competition and Markets Authority

Hey all!

My fuel is almost down to 2 bars, and I will need to fill up the tank soon.

It’s my first time doing this and my Honda Jazz EX is also my first ever car - so this is all new to me. 

Any advice? What’s the best fuel to put in it?

Thank you!

Another consideration could be whether you want to keep the car for a very long time. If you are afraid that cheap petrol will wear out your engine sooner, but you trade it in after 3 years for example, then this does not have to be such a big problem.

Although wearing out engines is not normally discussed in this forum. Hondas usually die of something else. See, for example https://clubjazz.org/forum/index.php?topic=4978.msg59022#msg59022 .

I do! See my post above (Last one on page 1) also the video of the 'Which' report posted above. Exactly what I said but in more detail

If you think your engine is at risk from fewer additives etc in lower grade  or budget or 'supermarket' petrol    you can then enter the debate on which is best and most economical. Should you always  buy expensive premium fuel that might have more additives. (or might not) ,  or buy the cheapest , and if necessary occasionally add  a bottle of octane booster or injector cleaner. 

Personally i have never had a problem with supermarket E10 petrol. .  A win /win. Cheaper and no need for an additive.

Diesel is another ball game.  Much more chance of being sold lower  quality 'truck' diesel, or one with fewer anti freeze additives in winter. (  In winter diesel fuel is normally refined to be a thinner viscosity  with  additives to reduce waxing and gelling. )  Not a problem with petrol.

[Lincolnshire Rambler]

I always use tend to shell fuels as it’s my nearest garage . I’m happy to pay more than supermarkets fuels as I believe the additives have a benefit over a lot of miles .
 

[Jazzik]

When I read something like this, my question is always: what do you think that benefit could (or should) be?

[Jazzdriver]

But if you realise you have put some diesel in by mistake do not drive the car. The fuel tank will need to be drained. "

Isn't the mis-fuelling problem confined to the risk of putting petrol into diesel cars. as diesel nozzles are too big to go into petrol tank filler pipes?  (You could, of course, mis-fuel a petrol car using diesel  from  a can........)

[CB72]

Solved! My nearest petrol station is a supermarket one and also a shell one, well what do you expect at Waitrose

I have tended to use E5 petrol when available rather than E10 for three reasons:

- a) I have assumed as alcohol has a lower calorific value than gasoline the greater energy (calorific value) in E5 fuel (5% ethanol) should yield more miles per tank than E10 (10% ethanol), albeit at increased cost.
- b) alcohol is hygroscopic so I reason using E5 rather than E10 may result in less water in the fuel system to degrade it (this can certainly happen when cheaper fuel is left over winter in lawn mower engines)
- c) the various 'go faster' and whizzo engine preserving additives in many E5 brands eg Shell

As well as a different method of combustion I think energy content may partly explain why diesel engines are more economical (Ethanol has calorific value of 23.5 MJ/l, gasoline 33.7 MJ/l, diesel 36.9 MJ/l)

But I may of course be kidding myself and falling for marketing hype not having run exact comparisons....

[Jazzik]

As for - a), in theory E5 fuel should give more miles per tank than E10. Here in Poland I only fill up with E5 (E10 not available). When I go abroad I always pour E10 into the tank and note: I have never noticed any (measurable) difference in consumption. If there is any difference, 1 Beaufort more tailwind or headwind will make a bigger difference.

Regarding - b): both E5 and E10 contain bioalcohol and are therefore hygroscopic. E10 is therefore (slightly) more hygroscopic than E5. As long as you don't hibernate your car next to your (Honda? ) lawn mower, I don't think you'll have a water problem...

Regarding - c): In my opinion the last sentence of your post certainly applies here...
