Can these Sparkplugs save 10% of my gas (MPG)?

[sad-lumina-owner]

It seems that these sparkplugs will ignite the gas sooner, and the claim is that the fuel is cleaner burning, more powerful, less pollution.

But could I achieve the same results by just advancing the timing 10 degrees?

And what is the danger of messing with the timing?

What will the ECM do?

I have a /94 lumina 3.4L dohc engine. Can I really improve my mileage further?

I recently did some research on gas saving methods for my blog.

I came across several devices including more advanced spark plugs. All my research (mainly online articles and worth of mouth) pretty much put the plugs in the bucket.

The expense of buying those plugs is better spent buying gas.


Your best bet for saving gas is a regular tuneup and learning to hypermile. Its hard to drive slower but it saved me a quarter of a tank my last trip (1 way!).

I saved about $35 in gas just by slowing down to the speed limit.

Can you explain why at least? or give some actual results of your research?

Obviously, if the plugs save more than $60 worth of gas, the opposite will be true.

Anyone who DOESN"T do all this doesn't care about saving gas.

As the 'rich man' said to Jesus, "I've done ALL those things since time immemorial. I need to SAVE MORE GAS."

Lets not fool around.

I'm going to install an HHO generator on this car, because I am simply unwilling and unable to pay $4/gallon for gas. That price is bullshit, and totally artificial anyway.

Frankly, I'd rather spend $100 on a handgun and shoot an oil executive, than pay $4/gallon for gas.

So lets talk what is practical: ALTERNATIVE FUELS.

I'll be burning anything and everything that costs less than gasoline in this car, including hydrogen, propane, and homemade deisel if need be.

And even if I only 'break even', I'll be ahead, because I avoided giving my money to crooks.

As a retired mechanic I have never seen any gadget or spark plug etc. that improves mileage enough to even pay for themselves. I agree with the person above that talked about keeping your car tuned & serviced. I run max air in radial tires & slow down. My 93 Lumina 3.1 gets up to 30 MPG @ 65 MPH, @ 75 MPH it drops to 26 MPG. This Lumina has 245,000 miles on it.

Well, I won't turn down the advice of a good mechanic, without hearing him out (I've been fleeced by enough mechanics to stay wary, naturally.)

So I am interested in just what the maximum inflation is for a lumina with good tires, ...38psi? 40? 45? 50?

Because I don't care if the ride is as hard as a rock if I can get more mpg out of this thing.

And while we're at it, what is the maximum load I can put in a /94 lumina? (excluding the driver)?

[Blue Bowtie]

Maximum pressure has nothing whatsoever to do with the vehicle. It is determined by the construction of the tire. Many tires have a maximum cold inflation of 35 PSIG because they cannot safely tolerate any more internal pressure. 4 of mt 7 vehicles have tires which permit 44 PSIG (3 BAR) inflation because they use 6 ply carcasses and are made to withstand the pressure. Obviously, the rolling resistance is slightly lower at higher inflation. There are other factors affecting rolling resistance, but inflation is very important.

Tires with a single ply sidewall construction are cheaper, but also tend to have higher rolling resistance.

The maximum GVWP is indicated on a label affixed to the LF door pillar, glove box door, or some other conspicuous place. The weight rating is indicated in total load, passengers included, so you'll have to do the math.

As long as we are on the topic, I have recently heard tire shops advertising that "filling your tires with nitrogen can save fuel." That is a completely misleading claim, based upon junk science and praying upon the unsuspecting. You could fill your tires with hydrogen and it wouldn't make a difference. The key is that the tires are at the proper inflation, regardless of what is used to inflate them. That said, nitrogen DOES have some benefits, however. Most importantly, pure nitrogen will help preserve the tire carcass slightly over time. However, most drivers will wear out their treads before rotting out the carcasses from inside. Also, pure nitrogen can have a slightly lower tendency to change pressure with temperature changes compared to atmospheric air, but only slightly (Boyle's Law is still in effect here). I believe that is the basis of the advertising claims. However, you can do just as well by checking your tire pressures periodically, just like the owner's manual stipulates.

Personally, I'm using a partial mix for inflating tires, with about 78% nitrogen.

If you start out with plugs that are so worn out or fouled that the engine misfires, replacing the crappy plugs with expensive "magic" plugs will absolutely improve your fuel economy, reduce emissions, etc. But then, ANY properly-functioning plug will do that, including the cheap ones.

If the plugs you take out are still working properly, no magic plug on earth is going to make more power/better mileage/reduce emissions.

Does anyone besides me remember how the US Government went after "magic sparkplug company" Splitfire, for LYING about horsepower increases?

Stop being so gullible. "HHO generators" are complete bullshit, and defy the laws of thermodynamics. It takes more energy to create the electrolysis that "makes" the hydrogen/oxygen gas than you get from burning the hydrogen with the oxygen you've produced.

MagicWater??? Are you crazy??? Get real.

Ok, I'm starting to like you now.

if anyone is interested I have some genuine snake oil to sell you to put in your car.

gas tabs, miracle plugs, magnets put on your fuel line... only serve to make the joker selling it to you rich and make you out to be a fool.

something not mentioned is getting a grappling hook and launcher to tie into semi's ... really helps on the gas mileage...

other than that, drive like a granny to get better gas mileage. stop tailgating which causes you to constantly braking/accelerating and lose mpg by causing all that gas you just burned in accelerating to transfer into heat in your brakes and also drive slower. figure out how to use the brake as little as possible ... also no use accelerating to the speed limit when the light a few hundred feet just turned yellow..... i dont know why so many people are in such a hurry to speed up just so they can stop at a red light

when the manufacturer designed your/our vehicles the correct plugs/plug wires/ignition coils have been tested and matched ..

using non OEM parts in the ignition system with the very close fuel/timing controls now in use My opinion it would not be wise to mess with these parts..

to ensure MAX MPG checking the plug wire resistance and replacing plugs every 30,ooomi with oem irridium plugs should do it quite good..

air filter and cleaning the MAF sensor also should help.

at the 100,ooomi mark replace the upstream O2 sensor.

step on power pedal slowly...put a little extra air in the tires 2-3 psi..check often ...

Computer feedback fuel injection? Overdrive transmission? Replacing plugs that soon is a TOTAL waste of resources if the engine is in good mechanical condition.

Iridium plugs in my Trailblazer have 92K on them. Pulled 'em out about a month ago, they looked so beautiful that even though I had already purchased new plugs, I put the originals back in.

Vehicle runs like new.

Unless the engine has driveability problems, I have no plans to check the plugs again until 150K+ miles.

Story isn't much different for my 3.4 Luminas; except they don't have iridium plugs. I bet the plugs are good for 50K+ miles.

Absolutely good advice. There are numerous common-sense approaches to making the most mileage. Don't use higher octane fuel than your engine needs. Tire inflation, wheel alignment, and brake function will all affect mileage (rolling resistance). Minimizing load weight will improve mileage - That's just simple physics. Take all the "Junk out yo' trunk" and enjoy better mileage. If you don't need to lug around a jack, tool kit, jugs of coolant and washer solvent, a winter survival kit, your surf board, four 15" subs in a 160 pound carpeted box, etcetera, toss that crap in the garage and get better mileage. If your car has aftermarket ground effects, a rear wing, a decorative fascia, and other body attachments, get them off and save the weight and wind resistance (most aftermarket and factory wings and ground effects hurt mileage). If you have to run two alternators to power your sound system remember that all that wattage is derived from gasoline.

In other words, just THINK a little instead of succumbing to the next gimmick that separates you from your money but gains you nothing.

I always find it interesting with a before and after photo. You could at least use the same camera angle. Who knows. Maybe it was two cameras and the same ignition sequence from different angles.

Mothballs work great in your gas.

when I saw this the first time my guess was they used a much lower voltage on the top picture..the lower picture they jack the voltage higher...

still there are still fools out there that will bight on this nonsense !
