#51 of 1246 Had to get the real thing. by mrdetailer Sep 07, 2001 (1:01 pm)
Let me mention what happenned to me to hopefully settle claims that Gasoline has all the additives you need.   For the past year I have had intermittent rough running on my 88 Dodge Aires. Did a Tuneup, replaced spark plug wires, rotor, coil, alternator and belt, alternator tensioner pully, and at least 2 vacuum hoses. All in response to this rough running. It would skip driving even at constant speeds. It would also die when stopping, or starting again at lights. There were times when I floored the gas and it wouldn't accelerate very fast.   My Mazda mechanic recommended a true decarbonization. I took it in yesterday. They hooked it up on a machine that ran a special fluid that connected to the fuel line. It ran for over an hour and cost about $130.00. Nothing went into the tank or oil. When I drove the car I immediately noticed the increase in power. No missing so far.   Bottom line, Gas alone doesn't always keep the fuel injectors clean.

surprisingly, mazda doesnt recommend adding fuel additives. of late, i've been adding a bottle of chevron techron concentrate before each oil change. i dont know whether its doing any good, but it hasnt done any harm either
#53 of 1246 fuel injectors/dirty engine coolant by almagg Sep 18, 2001 (8:58 am)
I had my fuel injectors 3-step cleaned at Jiffy Lube a few days ago. Yesterday I noticed that the coolant is now diiirty. When I bought the car a few weeks ago the liquid was clean and clear. Did they do something not right?
#54 of 1246 3 step method. by mrdetailer Sep 18, 2001 (9:21 am)
I've had the Jiffy Lube Treatment done on several cars. It puts an additive in the oil, runs a cleaner through the intake manifold, and puts a strong fuel injector cleaner in the tank. There should be nothing done that should have affected the regular engine coolant.   You might want to take it to a radiator specialist shop. They have a way to clean the inside of the radiator and engine.
#55 of 1246 Update on decarbonization. by mrdetailer Sep 18, 2001 (9:25 am)
The expensive treatment really seems to have done the trick. The Intermittent rough running, and dying have stopped. I can even pass other cars again. The engine has a lot more power. The mechanic recommends doing this every 30 -- 50 thousand miles, depending on the driving conditions.

#57 of 1246 Don't see how by mrdetailer Sep 18, 2001 (1:16 pm)
the 3 step method puts one bottle into the oil pan then oil is added, the second feeds a solution through the air intake valve and the third is added to the tank. Nothing should have touched coolant.   I've used this process about 3 times, and liked its performance.   Take it to a Radiator specialist.
#58 of 1246 Exhaust Carbon by celianeron Sep 25, 2001 (7:27 pm)
Do cleaners do enough to result in a clean looking tail pipe? My 89 Chevy Corsica only sees town miles, some 84K. With some cleaners and Chevron gas,it has a clean,no carbon, tail pipe. While, my 99 Ford E150 Van with 15K highway miles has a nasty black rimmed exhaust pipe. The Ford service manager says not to be concerned as no trouble light is activated. Anyway, I'm not running cleaners in the dirty Ford. This V6 seems to run rich. I look at others Ford vans for the telltale carbon. Is it time for gas cleaners? Ron

does anyone use fuel additives like injector cleaners and engine treatments? and do they really do anything?
