prashanthyr 0 Report post Posted December 17, 2007 I recently filled up at a Shell outlet and was told that Super Petrol is the only thing that is available. I would like to know if a. This is 91 Octane petrol like IOC Xtra Premium or 87 Octane like Speed, with additives? b. What happens if I have half a tank of regular unleaded and half tank of Super Petrol? thanks Prashanth Quote Share this post Link to post Share on other sites
