Best thing since the automobile was invented!

I swear by LUCAS products. I've been using Lucas for years. I have a 19 year young VW with 133k miles and I add Lucas once a month. She drives like a Carrera! I also have a 2012 E320 with only 32k miles (VW is my everyday ride). This car takes premium gas, however I might not drive it for 6-8 weeks. So, when I run her gas out and add Lucas at the next fill-up. Lastly, I ALWAYS KEEP LUCAS handy when driving trips longer than 3 hours. You never know what type of gas you might get driving in unfamiliar areas. Better safe than crying over buying a new engine.

Worked great for our 2002 RAV4!

It worked well for our RAV4. The car ran smoother after using it. Our car vibrated less especially when the car was idling. I would highly recommend it for older cars.

keeps my engine running like new

I use this once a week in my 2023 Ford Explorer because I drive a lot of miles but even at 81,600 miles it runs like brand new and gets just as good of fuel economy as day 1
