Why on earth are you using 99 RON fuel in a run of the mill car like a Toledo. If you look in the manual, its possibly even inside the fuel flap Seat will be telling you that 95 RON is fine for your car.

The only cars that require "super" fuels are truly exotic ones and the manufacturers will make it clear somewhere.

We have never used anything but 95 RON petrol and regular diesel in our cars (mostly supermarket) and in the 35 years or so since Asda opened a filling station locally we have never had a single fuel related problem.

Our Skoda Fabia 110 PS TSi runs on 95 RON as per the fuel flap and remember that all VAG cars use the exact same engines, most TSI engines are made at the Skoda plant for all the brands.

Save your money.

My local Esso garage is showing a "Headline Price" up on the display column as £1.119

I filled with Esso Synergy Supreme (99 Ron) as it is just a few pence more expensive AS A RULE

On checking my receipt at home I discover it was £1.349 - quite a difference

Yes I know I should check at the pump - and I will next time - but 23 pence a lite diference !!!!

Just a warning

Probably due to more 95RON petrol being used so storage tanks have since been refilled with cheaper fuel so the price goes down

I find my Skoda 1.4 tsi does run better on higher octane petrol but there is no real difference to fuel consumption - I tend to use Tesco Greenenergy as it's not that much more expensive. On our Fiat Panda there is no real difference between 95 and 99 RON.

Having said that I've forgotten what it's like to fill up with petrol. I've gone from 15k miles a year to near zero!

I thought it was 97 RON as against Tesco and Shell's 99?

I like the blurb from their website:

[Synergy Supreme+ Unleaded fuel also contains molecules that help to reduce friction and prevent wear and tear in your engine.***]

Molecules, you say?! That sounds quite technical. Where do I sign up?

The two local Shell stations are selling regular 95 at 107.9, and V-Power 99 at 136.9, which is truly extracting the micturate.

Ouch! Sounds like your Esso garage has little local competition, even at the moment with far less business. My local has a Tesco nearby and the price is now down to around £1.05 per litre for 95 Ron petrol.

I suspect that superunleaded is still expensive, given there's not much call for it (so they still have stocks bought at the higher wholesale price to get rid of), especially at the moment. When I filled up there about a month before the lockdown, I paid £1.22 for Ron 95 and recall the 98/99 being about 15p more expensive.

Moral of the story - always check the price at the pump before starting to fill up! Most filling stations don't show the price of superfuels on their illuminated signs (I think they should be forced to, by law).
