Can I switch back to 95 after adding 98?

[FinnLynn]

After using 98-octane gasoline, you can switch back to 95-octane, but it's recommended to first completely use up the 98-octane fuel before refilling with 95-octane. Vehicle owners are advised not to frequently switch between different gasoline grades. Once you've selected a fuel type, it's best to 'stick with it' and consistently use the same grade over the long term. The differences between 98-octane and 95-octane gasoline are as follows: 1. Different octane ratings: The grade number only indicates the octane value of the gasoline. The octane value is determined by comparing the fuel's knock intensity with standard fuels (iso-octane and n-heptane), where the percentage volume of iso-octane in the standard fuel that produces equivalent knock intensity represents the sample's octane value; 2. Different anti-knock combustion capabilities: Higher octane values indicate better anti-knock combustion performance; 3. Price difference: Generally, higher-grade gasoline offers better quality, and consequently comes with a higher price.
