Hi guys,
I live in ireland the price of petrol is expensive here at €1.25 per litre for 98 ron superunleaded (which is very hard to find a garage that sells it) and 95 ron unleaded at €0.88-0.93 cents a lawnmower is expensive to run,so i tried using an octane booster the performance levels are still retained,although when the weather gets cold and boost increases when driving the car hard the car does pink/knock a slightly (boosting at 1.4 bar +) the octane booster is "millers" it costs me around €7.00 per bottle and at fill up i add about one and a quarter bottles per tank it does seem to work but also leaves a rusty brown colour on the plugs and internal parts of the engine which i am told is ok.

Hope this is of some help.
