1) Do you have any before and after photos of this when used on a diesel motor like ours (particularly the hot/VVT side of the turbo)? Not yet, we are working on getting some in place for various vehicles but we don't have any yet I am afraid. As soon as we have some I will post them.
2) Is the cold engine start to ensure the surfactant (wetting agent) is able to fully coat the hot side components? It is in that Revive is water based so if we started with a hot engine a lot of the fluid treatment would be wasted due to evaporation.
3) What is/are the physical/chemical process(es) that actually removes these carbon deposits on the hot side? The carbon is removed in microscopic particles using the patented technology that Revive is based on.
I hope this goes some way to answering your questions?
Yes definitely, thank you for the responses.
Sounds promising but hopefully a few Duramax members will give it a try and we'll have an acid test for how well it really works on these trucks.
