Gumout Performance Additives would like to thank you for the great interaction you had with us in our prior Q&A sessions.
In a previous session, the focus was on gasoline direct injection (GDI) technology and related GDI performance issues – primarily the direct injectors themselves; however, this time we will focus on cleaning carbon deposits from the valves and ports of a GDI system which are more difficult to remedy.
While a GDI fuel delivery system can add power and increased fuel economy over many of the port injected systems, the intake valves and ports are now isolated from where the fuel is introduced to the combustion area of the engine. Now that the valves are no longer being sprayed with detergents (either in the fuel itself or in higher doses from fuel additives) by the port fuel injector, they begin to accumulate carbon build up through recirculated exhaust via the EGR/PCV valves.
Some solutions to these problems can only be conducted at a shop and by a certified tech. But there are now options for those with a bit more DIY expertise and they are much cheaper to perform. We discussed how to clean GDI injectors using Gumout fuel additives that contain polyetheramine (P.E.A.) in a previous session, but at that time we had not yet launched a product to clean the top end of the fuel system. That has changed; we now offer Gumout® Regane® Direct Injection Intake Valve & Port Cleaner aerosol spray. This professional strength, highly concentrated formula, utilizes the same potent PEA cleaning agent found in our Regane, All in One and Multi-System Tune up pour in fuel additives. This product is introduced via the air intake system and is a cost effective, easy to use solution for those troublesome GDI intake valve and port carbon deposits.
We’d like to open the topic up for discussion and share with you how this product can keep your GDI engines running smooth and any other GDI cleaning questions you may have.
Beginning today, the thread will be open for question submissions until 9 p.m. ET on Sunday May 22nd, at which time we will send them back to our full team of scientists, engineers and brand representatives to provide answers to as many of the questions as we can a few weeks later.
We are extremely excited to provide you with this service, but do have a few requests:
1. Please use this forum ONLY to submit questions. If you have previously posted questions on other areas of the site we will do our best to find them and provide answers, but your best bet is to repost the question in this thread.
2. Please understand that there will be some questions that we will not be able to answer. Some of our formulation information is proprietary, such as how much of a certain additive we put in our products, and can only provide feedback on our areas of expertise. Some testing information may also be proprietary but will offer up as much info as we can.
3. Please understand that we will not speculate on the products of our competitors, but we may be able provide you with ways to determine what they may have in their formulations. Not all fuel additives are created equal, so question claims and benefits and demand more information on what is in the product, what tests were used to determine efficacy and what were those results.
We look forward to your questions and thanks for your involvement!
