Has anyone else noticed worse fuel consumption (by about 15 %) when using Tesco 99 insteaf of V Power

Never tried it TBH

Is it cheaper than Shell and BP 99 ?

stick 5 litres of toluene in before filling up and get more power and better fuel consumption!!

nope, no change in MPG .. I use always run V-Power, but lately Tesco99

Me neither...

In my area... my a long shot! c5p a litre

nope, I use tesco 99 and i'm getting over 300 miles a tank and that's not on long journeys..... more than happy with it TBH

Bloody hell. I use the stuff too and never get more than 230 miles to a tank. I fill up when the DIS says about 0-10 miles to go...

bfettie - where do you get tuolene from?

i just drive like miss daisy i guess........

Inspite of having asked the question previously on the board, I'm still unclear if you actually derive any benefit running octanes in excess of 98...

Toluene's octane is 121 IIRC so you can easily work out a blend to give you a particular rating, but if the car is unable to compensate for the better fuel, what is the point?

Someone needs to fill their car with 98 RON and someone else with 102 RON and both head down to the dyno to see what happens...

SR71, read this and all will become clear ...no pun intended

I get it from rc stiven in dundee but any paint supply wholsaler should get it.
All modern ecu units have some adjustability of engine parameters and running 98 ron which is opitimum these should be in the middle of their ranges to allow adjustment either way.there will be an adjustment of 4 or 5 ron either way.all you are doing is taking advantage of this and giving the car a more energy dense fuel.toluene is also cheaper than petrol,think the last lot i got about 80p litre.I have been using it for years in honda type r's,within a couple of miles the engine runs smoother and quieter and blow me the rs did the same ! compared to bp ultimate,difficult to get v power here locally.I promise you,the difference is not small!!

Why not go the whole hog and use MTB,

How much do you guys get on a full tank????

Just filled up today with V-Power (£75.00) and if I get over 170miles (Town miles) I'll be lucky.

Is it safe to continually use these kind of additives in our engines though??
