What type of gasoline should a Corolla use?
2 Answers
The manufacturer recommends using unleaded gasoline with an octane rating of 92 or higher for the Corolla. Relevant details are as follows: 1. 92-octane gasoline has an octane rating of 92 and is suitable for mid-range vehicles (with lower compression ratios). The gasoline octane rating indicates its anti-knock properties; a higher number means better anti-knock performance, but it does not reflect the quality of the gasoline itself or imply that higher-octane gasoline contains fewer impurities. 2. The type of gasoline a vehicle uses is related to the engine system's compatibility. Essentially, it depends on the engine's compression ratio. Higher compression ratios result in greater power and efficiency but lower stability, requiring gasoline with higher anti-knock properties. If the compression ratio does not require it, using higher-octane gasoline will not improve performance significantly, though it may offer slightly better cleanliness and lower carbon emissions, but the effect is minimal.
I've been driving a Corolla for several years and found that 92-octane gasoline works best for it. The manufacturer's manual clearly states that regular models use 92-octane fuel. For my 2019 model, I always choose regular 92-octane, and the engine runs smoothly without any issues. Actually, I tried using 95-octane fuel before, but didn't notice any performance improvement—just wasted money. Remember, higher-octane fuel costs several dollars more per liter, and you can save a significant amount in the long run. Don't listen to others who claim Corollas need high-octane fuel—the engine's compression ratio isn't high, and it's designed to run more economically on lower-octane fuel. When refueling, always check the fuel cap or manual to confirm, as requirements may vary slightly by model year. In short, sticking with 92-octane is cost-effective and worry-free—no need to overcomplicate things.
