Some of the products we’ve talked about today have an inarguable benefit to them. Octane booster, for example, will always be a good addition to a petrol Audi because the company recommends 95RON fuel. That is not to say that the vehicles cannot run on regular unleaded or branded fuels, but the only fuel we can think of that have them performing the way they should is the 97RON Speed 97. Shell’s Super Premium is rated at 93RON, which is near enough to the recommend octane rating. However, both these fuels are usually found in select areas in the heart of big cities. Regular fuel is rated at 91RON.
As always, there are positives and negatives to everything. What I’ve put down here are lessons and observations from using different products and listening to feedback from different people, from ordinary people to those whose life revolves around cars. An overwhelming majority found a difference when additives were used – you can blame it on our bad fuel quality standards, or lackadaisical attitude to preventive maintenance – but your manufacturer might not recommend you to use them. Please go through your owner’s manual or check with your service centre to find out if using additives will void your warranty before trying them out.
