I've been using Shell's gas. I tried both 89 and 91 gas long time ago but noticed no difference in mileage. At about 33333km and due to recent high gas price, i added 89 for a few times. I noticed the engine felt smooth and powerful as usual, the gas mileage seems better too! anyone has the similar experience?
