Is it easy to refuel with 95 octane gasoline for a self-driving tour in Xinjiang?
3 Answers
It is relatively convenient to refuel with 95 octane gasoline for a self-driving tour in Xinjiang. The differences between 92 and 95 octane gasoline are as follows: 1. Different compositions: 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. 2. Different prices: A tank of 95 octane gasoline is slightly more expensive than 92 octane gasoline. 3. Different power outputs: 95 octane gasoline with a higher octane number is suitable for engines with higher compression ratios. This is because as the operating speed of such engines increases, the ignition timing in the cylinder advances. When the speed reaches a critical point, the air-fuel mixture in the cylinder may ignite prematurely before the spark plug fires, a phenomenon known as knocking. Increasing the octane number of gasoline can effectively improve anti-knock performance.
Last year, I took a self-driving trip around Xinjiang. In cities like Urumqi and Karamay, refueling with 95-octane gasoline was super convenient, with PetroChina and Sinopec gas stations everywhere, basically at every major intersection. But when driving to remote areas like the outskirts of Korla or the Gobi Desert, it became a bit harder to find, and some stations along national highways only supplied 92-octane fuel. My car is turbocharged and usually runs on 95-octane. I had to fill up with 92-octane a few times temporarily, and it was fine for a few hundred kilometers, but long-term use might cause carbon buildup. I recommend checking gas stations along the route using apps like Zhongyou Haoke e or Gaode Map before setting off, and carrying a portable fuel canister for emergencies. Xinjiang is vast, so route planning is crucial—don’t wait until the tank is almost empty to look for a station. The scenery along the way is stunning, but safety comes first. Make sure your car’s fuel needs are sorted so you can enjoy the trip worry-free.
When driving to Xinjiang for a self-drive trip, 95-octane gasoline is readily available in city centers and service areas. I had no issues at stops in Turpan and Yining. However, in more remote areas like small villages near Tianchi, gas stations are scarce, with some offering only 92-octane or diesel. Fellow drivers often mention that 95-octane, with its higher octane rating, protects the engine and prevents knocking. If you can't find it, temporarily using 92-octane is not a big deal, but avoid frequent mixing as it may cause engine shudder. Emergency solutions include using fuel additives or downloading the Sinopec Pocket App for real-time navigation. Xinjiang's road network is expanding rapidly, but stations in remote areas are sparse. It's best to stick to main routes like the Lianyungang–Khorgas Expressway and plan your itinerary carefully to avoid surprises. Gas prices can be slightly higher at times, so budgeting wisely ensures peace of mind.
