Once a year. Nothing beats it.
#64 of 1332 Techron
Jan 24, 2002 (12:32 pm)
Chevron's Techron additive (found in most auto stores and big retailers with auto sections like Target) is the only stuff I've found that really works - at least on my motorcycles. I've definitely noted increased fuel economy and smoother function. Things like that are very noticable in motorcycles because of the proximity of rider to engine. That and the fact that I tend to do all the maintenance on my bikes whereas the shops get the cars.

BMW did studies way back when I was still young and hands down the Techron removed carbon from valves, pistons and opened up fuel injectors. Now, this was 10 years ago and there might be some that work just as well. I have used Techron since I can remember and have cured many a starting-rough idling problem.

I drove across country in a SAAB 900 I used to own. I used nothing but Chevron gas during the whole trip. When I got to Oregon the car was running better than it was when I left. I was familiar with the Techron in the fuel and I was convinced of it's abilities after my trip. I now use it in my trucks twice a year to keep the fuel system clean. I have no complaints on it's ability to do the job.
#67 of 1332 Techron and Amsoil PI

I use Techron once in a while and on three cars I put the concentrate Amsoil PI in every tank. Does it work?
Never had an issue with fuel sytems on any car in last 6-8 years but would I have had any anyway?
#68 of 1332 Texaco Synthetic Fuel system Cleaner

I've tried many of the cleaners available. A couple of weeks ago I tried a bottle of Texaco's synthetic cleaner. It seemed to have worked very well. The engine seems to idle smoother and start quicker. Just a thought...

I've used Marvel Mystery Oil for years and have been very happy with the results. I do agree that Chevron's Techron additive is also good.

whenever my old 95 tbird used to start to idle sloppy and hard and suck a bit more fuel, and run tough......one tank with concentrated additive and a long drive did the trick. Sometimes a second treatment was necessary. But then after that the rough idle was gone and the mpg was back up where it should be.
Never any related reliability issues etc.
I highly recommend a treatment 2 times a year.....

Another reason to run an upper cylinder lubricant / cleaner in the fuel on a regular basis. Fuel system components (carbs, fuel injectors and pumps), need lubrication along with the valve guides and rings. In addition, the tips of the fuel injectors need to be kept clean. Any "baked on deposits" will alter the spray pattern on the injector. The fuel today is "dry" in terms of a lubricant. As I have stated on earlier postings, I use "Marvel Mystery Oil" (4 ounces to each 10 gallons of fuel) on a regular basis. I use this product because it is "reasonable in price", ($3.00 a quart K-Mart / $4.00 a quart in Pep-Boys), in my area of the country, and it does the job. I have used this product in all my Honda vehicles, (1997 Accord, 2000 Accord, 2000 Civic, 2003 Accord & 2004 Civic), and I have never had a fuel injector / fuel related / valve problem. YES, it is safe for the 02 sensor and the Cat converter. I also use this product in the fuel my 1999 MerCruiser 7.4 V8 marine engine and my 9 hp snow thrower. I have friends that use this product in the fuel of big oil injected outboard motors. I am not trying to start a debate over this issue, because I know that many people feel that this type of product is not needed, and a waste of money. I am just offering this information as a public service. My Honda dealer will add a fuel additive for the injectors at certain intervals of service. In addition, it is very important to use gas stations that pump "quality fuel", and sell "large quantities" quickly. Never purchase fuel from a station that is getting a fuel delivery. The incoming fuel from the tanker truck is churning up the tank in the station. You could be getting all kinds of contaminents in your vehicle's tank. -----Just my opinion. ----Greg

Great post. I totally agree with you in regards to using a quality grade gas. I mostly purchase from name brand stations, such as Mobil, Shell, etc. I also agree with you on not getting gas from a station that just got a delivery of gas. Now, getting back to Marvel Mystery oil. I have used that on our previous 89 Chrysler and after about 1.5 years I had to change the throttle body/injector and the O2 sensor. Not smashing on the Marvel Mystery oil, it may have been a fluke. From what I have read about the Mystery Oil is that it is great for vehicles with carbeurators, moving linkages, etc. However when we did receive our vehicle the dealership warned us not to use any additives in the fuel, cause it could damage the injectors. What they did recommend was to use a couple of tanks full of a high octane, high detergent gas to clean the system out. Next, I have read many posts about the rotten smell/odor, sulfur burn. It had not happen to us until I went from 89 octane to 87. I used 89 for about 4 tank fulls and wanted to see the difference with the 87 octane. Well I know now, my wife was in the car and it can make a person feel to throw-up. Well, thats my two cents.
