The cold isn’t a problem, just a reason to make some seasonal changes in your approach to driving your personal car. But only the smartest drivers know that
Every car manufacturer is obliged to indicate the parameters of the fuel on which his car should run. It is believed that most foreign-made passenger cars in Russia require gasoline with an octane number of at least 95. Even if in practice a particular engine “digests” AI-92 just fine. And a “magic” device (or rather an algorithm in the “brain” of the engine), called an octane number corrector, is available in every modern power unit. Thanks to this, the engine runs smoothly even on not particularly suitable fuel.
All this applies to almost any engine with a compression ratio of no more than 10.5. If the device has a compression ratio of 11-12, then yes: for that, “food” with an octane number lower than 95 is not a pleasure at all.
We also note that many car owners are sure that filling a turbo engine with AI-92 will be a death sentence for it. This may indeed be the case for some power sources. But real experience of driving modern “Chinese” cars, almost all equipped with a turbo engine, tells us: AI-92 for them is just what the doctor ordered. Although, of course, such power units are not abandoned from the 95th.
After covering the safety of the transition from AI-95 to AI-92, we will explain the significance of this event in subzero temperatures outside. The composition of 92 usually includes less valuable oil refining products, but with a fairly high octane number: isomerized and purified straight gasoline, cracked gasoline. More valuable compounds are used to make AI-95 – ethers, alkylates…
AI-92’s higher octane rating indicates that it is roughly more flammable: it ignites more easily and quickly in the cylinders. That is, it is more susceptible to explosion. Accordingly, AI-95 explodes less during combustion in cylinders – that is, it is initially less willing to ignite. In the cold season it is by definition more difficult to light anything at all. This fully applies to petrol.
Based on these considerations, it becomes clear why, other things being equal, the more flammable AI-92 is preferable for starting the engine after a long stay in icy weather conditions. For this reason, it is fully justified to switch to “winter gasoline” – 92 instead of 95. In addition, after warming up the engine, the octane corrector at least neutralizes the increased tendency of the AI-92 to explode.
