Chevron is what I use in all my vehicles but this time I added the bottle of Techroline Additive because I am the car's third owner and not knowing what's been in it in the past I thought I would give it a good cleaning. Texaco is about a dime cheaper around here but I think I'll stick with Chevron. A mechanic pulled a head off a Prelude I had with 50,000 miles and the first thing he said was "You must use Chevron" because the valves were clean as a whistle. Good Stuff but still only 91 octane.

Guys, sorry to bring life to an old thread, but Techroline is now called Techron, right? Same thing, right? I have been using the Pro-Gard bottle on the right that I bought from Costco, until recently when my store stopped carrying it. I then found the bottle on the left,,, I'm hoping Loren can chime in as to what the exact difference is and which bottle he uses. Thanks!

"Thank you for your inquiry. It has been forwarded to us here at Chevron Fuels Technical Service.

The ProGard and Techron products contain the same chemical additive. There is but one grade of the Techron product, while there are four grades of Pro-Gard. The Pro-Gard products are "Clean-up", "Fuel Injector Cleaner", "Fuel Injector Plus Intake Valve Cleaner", and "Gas Treatment".

The ProGard products give lower, less effective concentrations. These lower-concentration packages often sell for less. They have less "keep clean" and "cleanup" properties. They are also not concentrated enough to clean combustion chamber deposits. There are only subtle differences amongst the Pro-Gard products, mostly having to do with concentration.

Techron Concentrate Fuel System Cleaner is the most concentrated and will clean combustion chamber deposits. There is approximately 100% more active ingredient in the Techron Concentrate than the Pro-Gard Fuel Injector Cleaner. The active ingredient is Poly Ether Amine with a solvent carrier.

A bottle of Techron Concentrate Fuel System Cleaner, when added to gasoline according to the label instructions, results in an additive concentration roughly 10 times stronger than the dose in Chevron gasolines.

If you always used Chevron gasolines, you should be getting enough of a dose of Techron such that you should not have to purchase the Concentrate."

Loren, I figured you would have the answer at the tip of your fingers, as usual! Thanks again!!!

Try the Dension Icelink Gateway 500 unit at dension.com. Also available through BumperPlugs.com. I have installed thei unit in my 2004 996TT with PCM.

Chuck,

I think that is exactly what happened. The part that I am missing appears to possibly have three or four air ducts that face towards the REAR of the car. In other words, they appear to be flowing air rearwards that has passed through the radiator. Does that sound right? If so, is that part #10 in Lorens document???

I have had my '04 996TT for about 4 months now and RennTech has helped me tremendously! Thanks everyone!!!

I am now seeking some help in locating a part number. I found some plastic part damage to my front undercarriage the other day. In doing some research I found I need the following replacement parts: 996.504.123.00 (left front wheel housing protector) and 996.504.603.00 (left front air guide for fender liner).

There also appears to be a missing part (just plastic remnants left on the screws) that is approximately 20-25 inches long and centered underneath the front radiator? Looks like it may have been part of an air scoop system related to the air flow through the radiator? It appears to have about 4-5 attachement points from wheel housing protector to wheel housingprotector.

I hope that makes sense and thanks agaion for all your help!

ronbonner,

Hi there! I am having this exact problem right now after installing my Dension system a week ago. Did you get yours working???

Has anyone found this "handy tip" to work? I have the same problem and have tried it but to no avail....

Hi all,

I am in the process of installing a Pioneer Avic-Z1 in my 2004 C4s Cabriolet. I was thinking of installing a backup camera, but really can't find where to put the camera.

Any ideas anyone, or if you installed one, maybe a picture as to where you installed it. Thanks.

There are some cameras which are build into the frame for the license plate like this one:

Did you install a backup camera?

Anyone have instructions for removal/installation of the front and rear center console, cluster visor, and PCM radio trim on an 04 996TT?

:welcome:

It is the same as on MY02 and newer 996's. Been covered here many times. Please try our Search function.

New here. Tried the search but still did not find it. Please suggest a phrase to use.
