Great video 👍. You should do a follow-up video in a couple of weeks because if I remember correctly, CRC claims that it continues to break down the carbon deposits for a couple of weeks after the treatment.

I don't work on cars and I'm not a car enthusiast but recently found out about the CRC and Redline through videos like this. I have a 2018 Sonata that I thought was dual port and found out it is GDI only, it has about 28, 000 miles and I plan on using the CRC on it to clean the intake valves. Something to think about with dual port injection is possibly using Redline as well as it seems to work as good as CRC but you put it into the gas tank. I saw a video from someone on YouTube that used Redline kind of back to back on a high mileage car and it really cleaned the piston area. I think it was a bit extreme the way he used it but he was trying to see if it would work; once clean using it every 5, 000 miles or so may keep the carbon a bay. I could be wrong but using top tier gas mostly and CRC and Reline every so often may be beneficial in keeping carbon deposits off everything. At this point I haven't seen any oil change places advertising using the Valvoline Restore and Protect for an option.
