What are the consequences of using 98 octane gasoline in an Audi A6?
2 Answers
Audi A6 can use 98 octane gasoline. The Audi A6 is designed to run on 95 octane or higher gasoline. The correct gasoline grade is indicated on the inside of the fuel filler flap. It is widely known that cars should not use gasoline with a lower octane rating than specified, but using a higher octane rating is permitted. Below is relevant information about engine oil: 1. Function of engine oil: Engine oil lubricates and reduces friction in the engine, assists in cooling, seals against leaks, prevents rust and corrosion, and cushions shocks. It is often referred to as the 'lifeblood' of a car. Choosing the right engine oil and changing it regularly can maintain the engine in good condition and extend its service life. 2. Choosing engine oil: When selecting engine oil, the most expensive option is not necessarily the best. Instead, the choice should be based on the characteristics of the car's engine and the driver's habits. Engine oil can also be categorized by season, with winter-grade oil focusing on low-temperature viscosity ratings, while summer-grade oil does not require as good low-temperature viscosity ratings due to higher temperatures.
I've been driving an Audi A6 for several years and always used 95-octane fuel, but I've tried 98-octane a few times. There were no negative effects—the engine felt smoother and quieter after starting, possibly due to better combustion, but acceleration and fuel consumption were similar to 95. The issue is that 98-octane is significantly more expensive, costing over 30 yuan more for a 60-liter tank, which adds up over a month. The Audi A6 engine has a high compression ratio designed for 95-octane, so using 98 doesn’t cause harm, but the extra cost isn’t worth it. I recommend sticking with 95—it’s economical and sensible. Don’t forget regular oil changes and maintenance; keeping the engine healthy is key, and don’t fall for the hype around premium fuel.
