Question 1

Is this safe to get onto the throttle body plates and bushings??  spraying this after the maf will coat the throttle.

Accepted Answer

Yes. You spray AFTER the MAF, you do not want this to get on your MAF sensor. Your throttle body will be unaffected. Let car warm up first for 5 min. Make sure to have someone rev engine in neutral to 2k RPM and hold steady. Spray entire bottle until empty. Let engine heat soak for a hour (turn off engine and let it sit). Then go drive car with some good acceleration and get up to some quick highway speeds. Viola! Done

Question 2

Can this product cause damage to my turbo by sending carbon through the unit?

Accepted Answer

Anything is possible, but this product is designed to dissolve the carbon. It did not damaged the turbos on my EcoBoost f150. That is no guarantee that it will not damage your turbos. Know the risks involved. The biggest concern is with high mileage vehicles with heavy carbon build up.

Question 3

Can this be used with a turbo (diesel) engine? i've got a 2015 vw jetta tdi

Accepted Answer

Product itself says nothing about Diesel engines. But I wouldn’t use it in a diesel! If it’s designed to burn in gasoline engines most likely it can cause a Pre-Ignition in a Diesel, thus some damages to your engine. CRC hace specific products for Diesel engines, you could go check them out in their webpage. Hope this helps!

Question 4

If my car has 40,000 miles and it has never been carbon cleaned, Is it still safe to start now?

Accepted Answer

I don't think it is ever too late to start but 40k miles is not a lot.  If you were starting at 100k+ then there might be reason for concern.  At 40k you are probably doing it just about at the right time.  You could do it a little earlier or even a little later (+/-15k).
