How did she compare to the Alpine girls at Le Mans?Speaking to a Shell Scientist at the Goodwood festival of Speed (she wore a labcoat!), I was told that just one fill up with Shell V-Power will clean the engine internals . You can then fill up with Shell or other supermarket fuel (all the same really) for the next three fill ups. Which was a refreshing sell, as the adverts state that you always use V-power to keep the engine clean and economical.
She did say that you should use normal Shell in-between though.
I'd also presume the regular Shell fuel has similar detergents in it, and potentially does the same.why the recommendation to use normal in between???
I always use Shell (regular) with occasional V Power. If the engine has a knock sensor, the higher octane rating probably means more power too, though here, I presume we're talking about the detergents in the fuel cleaning carbon deposits more than just octane.
I'd also presume the regular Shell fuel has similar detergents in it, and potentially does the same.
The question to ask the scientist would be that if they recommend V-Power because it cleans the engine, why doesn't the regular Shell fuel clean the engine too, and should it then be avoided. Then watch them melt down in a science vs. marketing sort of way
Plenty seem to recommend the (higher octane) Tesco 99 (or whatever they call it now) too, so perhaps worth nothing that not all supermarket fuels are created equally?
What happened to five star!? The petrol not the band...

Blame the EU for that one, European countries I believe always used the RON or octane and standard/super on the pumps, reality was 3 star was 95, 4 star 98 and 5 star was 100 or 102, with or without lead, USA and Africa was and still is 92
