I'm fairly sure that the RON specification by car manufacturers for the fuel to use is a minimum requirement, enough so that your engine doesn't knock. So it shouldn't hurt to use 98RON. But feel free to tell me if I'm wrong
Yep run it on 98 ron, it's absolutely fine. I run all ours on 99 momentum, you only live once, until i find a bad batch then switch back to Shell V Power.
98 will be fine but it’s a total waste of money unless your car is mapped to use it and then the advantage would be marginal such that the map cost would be a waste of money too.
The map adjusts automatically. There's a minimal difference, but it's most noticeable in pickup when it's hot and aircon is on. Other than that, minimal difference but mine does run quieter on V-Power...
My A2 is a diesel but being surprised Audi would supply a petrol engine that runs 91 ron I decided to look at the engine spec. Compression ratio 10.5 to 1.
I have two petrol engines with that ratio and both get the highest ron petrol I can buy. They run smoother, accelerate faster and give better economy that more than compensated for the increased fuel costs.
Standard unleaded makes the engines feel constipated and prone to stalling. Give some 98 a try; I suspect you will be pleasantly surprised.
