“Carbon build-up” is a common problem that can have serious effects on your engines’s performance. Depending on the severity, these effects can range from cold-starting problemsignition misfires, and drastically reduced engine performance, just to name a few. This is especially true for vehicles with direct injection engines, like our customer’s Audi RS4 pictured here. We shed some light on the mysterious-sounding issue with some pictures we took today so you can see exactly what we mean. All of that build-up has occurred in just 37,000 miles!

Here’s a good article with a lot more detailed information on this phenomenon:

To slow down this process, it’s important to have high-quality oil changes performed at least every 5,000 miles. Eventually though, you will probably need to have that carbon cleaned. We can clean up carbon build-up with a process that includes “walnut shell abrasive blasting” which is both effective and safe for your engine. You can see how much better it looks in the “After” picture below!
