Premium fuel

Does anybody here use it in their own vehicles?

Nope although I know people who have performance engines in their cars that require the higher octane you get with premium fuels.

I’ve always had bog standard cars designed to run on big standard fuels. All fuels are the same composition but the difference is in the additives, some claim better fuel economy etc, cleaner burn and so on. Personally I’ve not come across a situation where I feel that I may have benefitted from adding a tank of premium fuel now and again.

Cheers. Never bothered with it in the past but it’s cured a horrible rattle I had coming from the cat converter on my car. Just interested to know others have found any benefits

I’ve no doubt some will say there is a benefit and will undoubtedly be more mechanically minded than I am and will be able to say why a premium fuel is better and what it can improve etc.

I’m just saying from my own experience I’ve not noticed much of a difference. It could be that I put a tank of premium fuel in and all of a sudden my car feels like the red car/blue car from the Milky Way advert but I doubt it.

Regarding catalytic converters I’ve often glfoujd they react to heat, ie the building up of heat, therefore a decent longish range motorway cruise often helps sort them out, moreso if you only do smaller trips most of the time.

I put standard diesel in my car, never noticed any difference, but have a 2 stroke stihl multi tool for gardening in garage and always use super unleaded for that because it works better on the E5 than the E10 petrol.

Peculiar.
If you revert to ordinary fuel does the rattle return?

For those who notice a difference in fuels in standard road cars, get someone else to fill your car for you, with random grade fuel (daresay you`ll need to trust them with your card) and see if you can then tell the difference: a blind test.

There are differences, but on most engines, in most cases, very minimal.

Yes, my daily drive (I do an average of 30 miles per week) is a 20 year old Merc 320 which is a V6 3.2 litre petrol and tbh I’m not sure if it would run on E10 so it’s Shell
V power for it every time.

I used to run Sprinter vans between Middlesbrough and Barcelona regularly and found that when I drove and set the cruse at 100kph for the entire journey I’d get around 100 miles more from a tankful with premium fuel as opposed to “normal” fuel. I’m not sure if the extra mileage warranted the extra cost tbh, but it made me feel happier.

I use normal stuff but on occasions that my motorbike will be laid up for winter I start putting premium in towards the end of summer, purely because normal fuel is E10 (premium fuel is E5) and ethanol plays havoc with carburettor rubbers/ seals etc as it attract moisture over time while stood still.
I should think any motorbike or classic car owner knows what I mean!
I understand this doesn’t affect fuel injection vehicles though so I always use normal in my car.

Car runs on premium,van gets an occasional tank full of premium,bike runs on standard.

They can stick that new E5 stuff made with sweepings up :wink: where the sun don’t shine.

For the Diesel it was previously supermarket fodder, but now i can get Texaco for only 2 or 3 ppl more so branded it is.

I’ve yet to find out as I’ve just stuck to premium fuel since the rattling disappeared as it was very annoying.
Can’t say I’ve noticed any difference in fuel economy to be honest but it’s done what I wanted!

E10 is the worst of all worlds of low octane rating with higher ethanol content.The 1.8 Zafira has laughable pinking if running on the stuff.It runs fine on E5.Most engines won’t run at peak efficiency on 95 octane fuel.
The base petrol must be garbage to end up with lower octane with more ethanol which is an octane booster.

It’s the E10 which is rubbish.E5 is 98-99 octane v 95 for E10.

(Thinking you meant E10?)
I had a week’s holiday in Ireland, one benefit was they still only have E5. [emoji106]

Probably, only fill up once in a blue moon unless lpg is unavailable, whichever is the new brew i donnawannit :smiling_imp:

I did…

Fill my Fiesta with Shell V power unleaded for the 3 years I owned it. I recently traded it in and pointed this out to the dealer. He larfed and said it made no difference to the book price.
The teeny tiny consolation prize is the discount on coffee, food from the Shell deli selection and money off petrol offers that come through the Shell V Power app.
My mileage at the time was minimal and I don’t think it made much difference.

Sorry…

But you get all that with the Shell app, doesn’t need to be VPower.

Thank you…

I was aware of that.

My car’s 22 years old, so I daren’t risk E10. I always put E5 in.
