My car’s 22 years old, so I daren’t risk E10. I always put E5 in.
My car is 20 year old lol
Probably the most reliable car I’ve ever owned too. I swear by late 90s cars. I reckon the late 90s was the sweet spot between the crap reliability of the British Leyland era, and the awful over engineering of recent times.

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.
Thats a lot when you think about it though isn’t it 100 miles. Some good replies here.

Agreed.
Cheapo supermarket E10. Or whatever is cheapest. think its E10.
Considered Premium can go for almost £2 a litre at some places, no way I am using that crap lol.
I’d sooner sell the car then use it at that point.
I do think I can get 10% better mileage on premium over e10 now that is the standard petrol. In practice can recover the extra spend at the pump if the difference is less than that.
That said I don’t use it every fill except on the bike as it only gets sporadic use.

+1.
For some makers you can go a bit later well into the mid noughties because, well, they’re very conservative people the Japanese car makers and none the worse for that, ie if it ain’t broke don’t fix it runs deep in their ways, Toyota a prime example.
My own cars of the era are seriously rutsproofed and serviced above and beyond, by me, got no intention of replacing them with any of this overtechnical junk.
Talk of fuels reminds me of my late grandfather telling me about the petrol you used to get (when available) during the war. It was called pool petrol, but I’m not sure if that was a brand name or a ministry designation, and IIRC according to him it was only about 65 octane and would barely burn! He also told me about adaptor kits you could get which basically consisted of a 1/4 inch machined steel plate that fit between the head and the block to lower the compression ratio.
My Landrover Discovery 4, used to hate cheap supermarket fuel, I always had to put Shell diesel in it and then it would run fine, up until the crankshaft snapped, which seems to be a common fault with the 3.0l tdv6!!! 
It will be interesting to see what will happen to E5 since the launch of E10 as the government has said it will ensure the supply of E5 fuel is maintained via the higher octane super grade but warns the protection would only last for five years.
This is the “longest period” government could impose the regulations before it must be reviewed as vehicles come to the end of their economic life. 
There will be a review in 2026.
Rember when unleaded started coming out I owned a cavalier. Was unsure about using it.
For ages used mix it up a fill of 4. Star fill of unleaded.
Eventually ran it on unleaded.

Yeah, I was putting a bottle of lead additive in the tank back then.
I read the RAC have been pushing for the DVLA to let affected car owners know in advance to consider their options about E5 review in 2026 That’s quite telling.

That’s interesting 
cheers for posting that
yes our firm runs premium diesel in all wagons
Bit of a paradox for me with my little Honda NC50.
On the one hand it has a carburettor and ethanol rots carburettor gaskets so E5 (premium fuel) is better than E10. On the other hand it has a low compression engine which runs better on low octane fuel so E10 is better than E5.
md1987:
Does anybody here use it in their own vehicles?
Yes , always put it in mrs fiesta st , was asked if it was using that when it was remapped , was so no issue
Mine just has normal / cheapest fuel

That’s a little belter! Love the backbox
When E5 basic petrol was phased out, I put some E10 in my old banger Vauxhall - and the engine seized the very next day.
I don’t think that was a coinicidence. The science is that E10 is hygroscopic, which means your fuel gets damper at double the rate of the outgoing E5 fuel.
The damage then comes from a freshly-started (cold started) engine, when you’re likely to have cylinders full of dew moisture, and the rust that will quickly build up on the inside of the cylinders.
I learned my lesson then, and from then onwards - I always put “premium unleaded” which is the only form of E5 still readily available…
I don’t fill up at those establishments that take the ■■■■ on their premium price (often “undisplayed”) and instead stick to Sainsburys or Tescos where the E5 premium unleaded - is 5-10p more than the regular E10 brand that is NOT SUITABLE FOR OLD BANGERS!!!

95 octane isn’t suitable for anything with a compression ratio above 8:1 more like less than 7:1 with forced induction.
The scammers pushing this rubbish fuel are just relying on knock sensors and auto ignition retardation to make it remotely useable.Which usually won’t react in time anyway when it’s knocking it’s already too late.
