I recently purchased a 1993 Audi 80 and want to know which oil viscosity is recommended for optimal performance and longevity of the engine. The manual suggests 5W-40 or 10W-40, but I've heard conflicting opinions. Can anyone provide some insight based on personal experience?
ReplyI've used 5W-40 in my 1993 Audi 80 for the past 10 years and haven't had any issues. It's the recommended viscosity for colder climates, but also works well in warmer temperatures. Just make sure to use a high-quality, synthetic oil from a reputable brand.
I've always stuck with the 10W-40 viscosity for my 1993 Audi 80 and it's performed well for me. As long as you stick to regular oil changes and use a good quality oil, you shouldn't have any problems.
I personally prefer using a 5W-30 oil in my Audi 80. It's slightly thinner than the recommended 5W-40, but still provides adequate protection for the engine. Plus, it can improve fuel efficiency and performance in warmer temperatures.
