thedude92

Hello again, Thank you very much for the detailed replies. During my trip this weekend I had half a tank of OMV 95 octane petrol left and filled the tank up with OMV 100plus. I chose OMV since the majority of posts from our local community recommended them for quality fuel in Romania. After refueling the engine ran more smoothly on this 50-50% mix and the fuel consumption decreased a little bit. It will take me a few more trips to gradually use up the remaining 95 octane, but I liked the initial results. @Ootohere - thank you for the .pdf printout with the content of the fuels in the UK. It gave me a better idea what to look for. Indeed, the engine seemed to appreciate the 100plus. @Stonekeeper - I was just being very cautious, before posting I initially tried looking up how to achieve 98 octane petrol by mixing fuel ratios (wasn't sure if mixing fuels follows a linear relationship) and came across posts that said some engines don't get along well with higher octane than recommended in the manual - I agree that the Skoda's manual carries the greatest weight and it states in black on white that it accepts higher octane, but wanted to double check with other people's hands on experience 😁 @nta16 - higher cleaning additives content sounds like a good reason to get the premium petrol, I'd rather prevent & delay issues rather than fix them - I was just a bit stuck with the fact that 98 octane was very hard to find and wanted to be sure 100 is safe to use, but I've overcome that concern, thank you! @leolito - I checked with the local community, they recommended OMV/Petrom, but advised against refueling at Lukoil; couldn't find any lab results so I'll have to stick to the popular opinion from the forums - right now I'm running a 50-50% mix, but I'll try out increasing the proportion of 100plus octane petrol over the next month to see how the engine behaves Cheers!

Hello everyone, I recently acquired a Skoda Superb Mk3 (2019, 272PS) and am trying to make sure I don't make any regretable mistakes with the petrol I use. The dilemma I am facing is that there the majority of petrol stations here provide you with 95 RON and 99 or 100 RON as options. I checked out the car's flap as my 'source of truth' and it specifies "benzin RON/ROZ 98 min. 95", attached file skoda_flap.jpg. I was hoping someone has already been through this scenario and could share his experience (hopefully positive ones!). Short version: I am tempted to use 100 RON, but am afraid about screwing up the engine. Long version: I found this thread, which gets close to my question, but doesn't make clear statements about using higher octane values https://www.briskoda.net/forums/topic/386759-petrol-octane-rating/ I've downloaded the car's manual, using the VIN to make sure it matches, and found 2 relevant pages: Page 266, attaches file skoda_manual_266.png Here the wording is a bit confusing for me, since it mentions 1) 'specified petrol 95/ min. 92 RON', 2) 'unleaded petrol min 95 RON', and 3) 'prescribed petrol 98/(95)'. Based on the fonts they used, I think these are 3 distinct ways they specify the fuels on their flaps and I believe that I fall under the first formulation, but with 98 and 95 as RON values, instead of 95 and 92. Page 266 didn't clarify matters for me, because I was searching for an upper boundary for the octane number and it provided a recommended value which I cannot find in petrol stations. Page 267, attaches file skoda_manual_267.png Here the Note touches the higher octane topic with all 3 points: ■ Unleaded petrol that has a higher octane number than that required by the engine can be used without limitations. ■ The use of petrol with an octane rating higher than 95 RON in does not result in either a noticeable increase in power nor lower fuel consumption in vehicles for which unleaded petrol 95/min 92 or 93 RON is specified. ■ On vehicles using prescribed petrol of min. 95 RON, the use of petrol with a higher octane number than 95 RON can increase the power and reduce fuel consumption. So... I'd conclude it's OK to use 100 RON? --- P.S. I mainly use the car on holidays, only minimal driving in the city, so fuel price isn't really critical.
