I almost always gas up at Chevron. All thier gas has Techron. Should I gas up somewhere else??
My guess is no because the concentration of Techron in pump gas is probably very low. But that is just a guess. It probably is also expensive so they can't be putting much if any in a gallon of gas. I was using their concentrated Injector cleaner in the black bottles. It was like 12oz treats 20 gallons of fuel. Started using the product when the car had something like 15-20,000 miles on it.
It does say right on the bottle to only use it once per oil change and to use it just before you change your oil. But I was addicted to the stuff because the engine ran so so good when on it. I wrote to Chevron and they sent me 2" of paperwork about the stuff and how it works.
They even told me in a cover letter that some will get past the rings and into the oil so don't use it often.
I figure because I was using Mobil 1 oil and changing my oil every 2,000 miles (I loved this car) along with a good filter, I could get away with using Techron every other tank full. I was wrong. There was nothing left of my engine (Acura Legend) after 66,000 miles. Cylinder leakage was 25% pass the RINGS. Under air pressure you felt WIND coming out the oil filler cap.!
The REAL joke of the whole story was this. While trying to figure out why my engine was running so poor when it had 60K miles on it, I found a clogged injector.!! I was buying this stuff by the case. I still had a clogged injector. But it did not matter. Once I took a compression test and leakdown test the game was over.
I drove the car another 10-12K miles and dumped it.
Yes I abused the product. But the fact I still had a plugged injector should make you wonder how it could ever work in the concentrations they recommend.
So my question is what's the point in using it at all. It would be cheaper and better to just change the injectors when they clog.
