    BG44k Injector Cleaner - Any Good?

    As I don't "Race it like I've stole it" I was looking to get some of this to ensure that there is no muck building up.

    Is it any good or even worth the effort? From what I've read on various forums people can't praise it high enough.

    What do you guys think?

    Re: BG44k Injector Cleaner - Any Good?

    I been using BG44K/CF5 since I had the DFI R8. The amount of carbon purged using the product was minimal. I believe BG44K is more effect with an EFI engine. Since BG44K contains PolyEther Amine (PEA is proprietary of Chevron), which is the primary cleaning agent. BG44K does help in keeping the fuel lines, combustion chamber and exhaust valves clean, unfortunately it's not as effective in cleaning the intake manifold and intake valves.

    Recent, I've started using BlueChem, a German product, of similar intent. I get a lot more carbon being purged. At this point and time I'm not making any conclusion with the products, except they do help to a point, which is still better than nothing.

    Yes, we are still limited in our ability through such cleaners to clean the intake manifold and intake valves. Eventually, we will have to resort to specialized equipment to clean that intake manifold and intake valves. A recent experience through the use of such specialized equipment (produced by BG) to clean-up my brother's DFI GOLF GTI was extremely successful.

    You will have to drive the R8 aggressively. Avoid long idles and stop/go's as these conditions will increase carbon build-up. Aggressive driving does help in dislodging those carbon deposits. Driving habits does help.

    Here is a link to another product.

    Nice technical bulletin.

    I am having the occasional unstable idle at start. I've been blaming fuel. I notice that it occurs when its hot outside but the car doesnt rev at 2000 rpms at startup say after it has been sitting for 6 hrs.

    I drive it aggressively and have no power issues.

    That's a good article to explain the constraints faced by a DFI engine. Similar to what was done in that article, I'm using a fluid 'atomizer', porting the 'atomized' cleaning solution through the air intake. Apparently, Toyota has an additional fuel injector in the intake manifold which assists with the cleaning of the intake manifold and intake valves. However, such a design approach increases overall fuel consumption.

    In regard to the higher initial RPM's not happening during engine starts, it is a normal occurrence for me since the ambient temp in Malaysia is always high. I believe the ECU recognizes the actual oil temp and adjusts that initial RPM accordingly. Brilliant!!! I don't like those initial high RPM's to contribute to more wear and tear during those initial engine starts, esp. when those bearings are devoid of lubrication. I do not have the idle stability issue you described. My fuel is a pathetic Euro 2 standard. So I don't think your fuel is your problem!

    For those who have put in effort towards manifold & valve cleaning, you'll need to 'race' that engine in order to purge and delay the re-accumulation of such deposits. That RS4 engine was designed to race! People who 'race' their R8's from day one will have less issues with carbon deposits.

    From experience, my effort has paid-off, (attested by effortlessly 'eating' those F430's and GTR35's), and the feel of the engine performance is very much like the first days with the car

    You should try to 'exercise' your R8 whenever you get the opportunity, otherwise she's going to eventually 'hate' you
