fuel additives

ya its a 6 cylinder

just use chevron. techron is a HELL of a chemical. chevron actually sells it to other companies because of its effectiveness. in fact it was so effective is started to destroy poppet valves in GM motors (it was a bad design anyways, but the techron caused it to go over the edge)

thats really the only fuel "additive" you need to keep everything clean inside.

edit: btw. the techron destroying the poppet valves was on the older gm's...not like your current impala so dont get nervous lol

lucas fuel additive FTW

makes my truck run like brand new

Here we go again...

Dont forget to check the O2 sensor and MAF as they tell the engine JUST how much fuel is needed to maintain a proper A/F ratio,
also if you doing the plugs you might want to also upgrade the wires and coil (MSD is a good one)

There's way more to ignition systems than MSD.

Might be a good idea, get a bosch one
also the plugs would be good too, I got the P4s and I noticed a little difference at idle and acceleration, I probably wouldn't of gotten them except I got a killer deal on ebay on em'

Bosch plugs are SHIT. Get what is recommended for your car. There are very few engines in cars built in the last 10 years, that you can improve by changing plugs. Don't you think if simply changing a spark plug would yield better mileage, the manufacturer would have done it? And it's been lab proven, that the only style of multi-electrode spark plug that works is a V style, like a Splitfire. The only difference being, that the spark acr'd between the upper electrodes, rather than between the upper and coil electrodes, moving it slightly further into the combustion chamber. For a spark plug to ACTUALLY provide the 4 sparks that the Bosch +4s claim, it would need 4 coil electrodes, and 4 sparks. On Bosch +4s, you don't get 4 sparks or 4x the spark, you just 4 places for that same old spark to jump to.

hmm is there only 1 02( oxygen sensor ) on the car?

Most likely 2, and often as many as 4-6.

hmm i c how much MPG's do ppl usually gain after getting new 02 sensor and MAF

You won't see a gain, you'll see a reduction in loss. And unless the MAF is REALLY bad, you're better of leaving it alone. And if it was bad enough to need cleaning, your car would lurch, jump, idle poorly, and generally drive like shit. If it's idling and accelerating smooth, leave you MAF alone. It's fragile, and expensive.

Depending on how F'ed it is and your engine I would say 5+mpg for the O2 sensoralso you can test the O2 sensor with a accurate multimeter, or just get a new one for like 50bucks

clogged MAF can cause the same problem you can clean your MAF if you want to save money (as MAFs arent cheap here is how)

use ELECTRICAL CONTACT CLEANER. This is the only thing you should use to clean your MAF. Only ELECTRICAL CONTACT CLEANER. No windex, no carb cleaner, no brake cleaner, no rubbing alcohol, and no Q-Tips.

Step 1: Open the hood and locate your air box. If you can't find it...please stop right now and have a friend clean your MAF for you.

Step 2: Open the airbox and move the assembly up to give you room to work.

Step 3: Locate the plug on the bottom and move the grommet down to give you room. See picture.

Step 4: Take the flathead screwdriver and pop the four tabs holding the assembly in.

Step 5: Reach in and disconnect the wiring harness from the MAF. Don't rip the wires or anything!

Step 6: Remove the assembly. Locate the MAF and remove the two screws holding it in.

Step 7: Spray the living daylights out of the wires. Do NOT touch them. ABOSOLUTELY DO NOT TOUCH THEM. Those wires are very small and delicate. If you break one of them....it's a $150 mistake.

Step 8: The installation is the reversal.

Do this once every 6 months and your MAF will continue to be clean and your performance won't suffer.

ALSO dont forget about your plugs and wires

Cleaning your MAF is a huge risk, unless is NEEDS to be cleaned.

An O2 sensor would have to be absolutely obliterated to cost you 5+ mpg, and to test it with a multimeter, you would also need a torch, and something to hold it up for you. Testing it this way often destroys it. It's designed to withstand certain temperatures, and it changes the amount of voltage it puts out depending on it's temperature. You have to heat it up and check to see what the amount of resistance is at certain temperatures. Usually, as soon as it cools down, even if it tested good, it is no longer worth a shit. Getting up to operating temperature via a gradual increase in air temperature is what it's designed for, not being heated very quickly by an open flame that is twice the operating temperature. Keep in mind, the element inside of it, it ceramic, so be very careful not to drop or jolt them either.

SuperchargedRS, you're not allowed to give car advice any more. Shut up.

uhh i dont get it, MSD is a manufacture not a component of a ignition system, I mentioned them as ther product line is readable avalibe at most retailers and they make a good product

Shit; really they seems to work well for me, I did not say they were the best plug out there, infact I said that I wouldnt of gotten them if I hadent bought them for a heck of a deal. How would it provide 4 sparks, when it only ignites once... did you think that they said that the plug would fire 4 times??? I never heard that before.

You won't see a gain, you'll see a reduction in loss.

A reduction in loss is a gain dumbazz, ahhh the southern educational system at work lol

Hold it to a torch wow, I never would of thought of that, I was thinking of leaving it on the car and testing with a high impedence volt meter, the best way to hurt the o2 sensor would to be to apply voltage to it.

SuperchargedRS, you're not allowed to give car advice any more. Shut up.

Hmm, all the facts you are stating are anecdotal at best, also based apon what you stated on the other thread I commented on, and with how it looked like you read something I said about the car dealerships I tke it you dont like me? this is funny as you dont even know me! I know computers are new to texas (you know that whole "internet" thing) but try to be less of a pretensiously arrogant prick!

If you dont believe me about the o2 sensor here is a article written be a fellow texan, perhaps he phrased it in a way you might understand

are you talking about just fueling at cheveron stations? or actually buying a additive?

 

[da_tank 10+ year member]

add 6oz. of diesel, that'll get your temp up and clean the injectors.

 

[amoffitt 10+ year member]

what about seafoam. any of you use that?

 

[whiteZ714x4 10+ year member]

Seafoam is awesome, best stuff that I have ever seen/used. I can put it through my pvc line or brake booster line and run my truck for 15 minutes and tons of smoke will come out of my exhasut tips, due to the excess carbon burning off. Its only like 7 dollars for a can at autozone or somewhere similar.

 

[amoffitt 10+ year member]

is there one where you can just pour it into the tank?

 

[amoffitt 10+ year member]

bump

 

[19psi 10+ year member]

just keep using chevron fuel. the techron is already in it. it's enough to keep everything clean.

i pretty much agree with ferendon on what he says.

if your 02 sensor is bad, teh ecu will tell you by setting a check engine light.

same with the maf sensor.

bosch plugs=junk

platinum plugs=junk. they actually decrease hp and mileage. the ONLY reason platinum plugs came to be is that in some cars, it's a huge pain in the *** to change plugs. the mfr's needed a plug that would last a long long time to offset the labor cost of changing the plugs. plat's last 100k miles.

the reason they don't make as much hp and fuel mileage is that each tiem the plug sparks, a tiny bit of the electrode is used to make the spark. well, platinum is very hard, not much is lost every time. that's great for longevity, but bad for power and mileage.

the best plug for power and mileage is a standard copper plug. the dont' last as long but they make better sparks.

it depends on if you can do your own work or not. if youcan and don't mind doing it, use a copper plug.

 

[amoffitt 10+ year member]

i gotcha. what makes up techron?

 

[19psi 10+ year member]

i have never looked at the ingredients. possibly they're not even disclosed; i think chevron is pretty guarded with that kind of thing.

 

[amoffitt 10+ year member]

ahh i gotcha so just fuel my next tank with cheveron gas and it will do the trick?
