XTreme fuel treatment

E90/E91/E92/E93 (2006 – 2013)
The E9X is the 4th evolution of the BMW 3 series including a highly tuned twin turbo 335i variant pushing out 300hp and 300 ft. lbs. of torque. BMW continues to show that it sets the bar for true driving performance! — View the E9X Wiki

XTreme fuel treatment

Has anybody heard of and or used Extreme fuel treatment?
I am trying it out now. It claims that it increases fuel economy, prolongs engine life, improves performance and reduces emissions. Also claims you can use lower octane fuel.
The claim that you can use lower octane fuel is the one I wonder about.
You can supposedly go from 93 octane to 87 with no negative effects. My concern is that it is not an octane booster, so how can this be accurate. Most BMW’s require a minimum of 91 I believe?
I also recently ordered stuff to improve the performance and power and sound of my car from Extreme Power House including JB4 with Bluetooth, BMS intake, VRSF chargepipe, downpipe and catback.
I read on N54 tech.com that you should use higher octane for better performance and power.
I am on my second tank of gas now using the Extreme fuel treatment and 87 octane gas. I am not noticing any issues or anything with the way the car runs so far.
Once I install all of the upgrades, I’m thinking I should use at least 91 or go back to 93 like I was before I started using the fuel additive.
You can check out the Extreme fuel treatment @ Fuel My Ride.org or www.syntekglobal.com for more info. on the product.
Any opinions and input on this would be greatly appreciated.

Well, you probably won’t notice, how the car will drive using lower octane fuel till later. The big thing about running higher octane, is keeping the valves cleaned. The 93 burns a lot cleaner keeping the engine a lot cleaner. I wouldn’t using anything less

Extreme claims it’s a Combustion Catalyst – extends the burn rate of fuel during combustion to provide a more complete fuel burn resulting in increased gas mileage, fewer harmful emissions and less carbon build up on engine parts.
Detergents – removes harmful deposits from fuel pumps, injectors and throughout the fuel system.
Lubricants – Provides lubrication to pistons, fuel pumps and injectors, reducing friction and prolonging the working life of the engine.
Fuel Stabilizers – Prolongs the life of stored fuel.
Polymerization Retardant and Dispersants – Reduces sludge buildup in fuel which can filters.
Rust and Corrosion Inhibitors – Prevents tank and fuel system corrosion caused by oxidation and condensation.
Demulsifiers – Helps separate water from fuel.

This is taken directly from a pamphlet I have.
It does not claim to be an octane booster however.

I’ve no intention of dropping the octane.

Not an issue in directly injected 335i – runs fine on 91 octane.

Fuel additives are snake oil

More accurately, valve deposits are an issue, but the fuel never reaches the valves in significant quantity to clean them so it doesn’t matter what is or isn’t in your fuel.

I suppose there could be an additive that might reduce the creation of deposits, but I doubt it. You ultimately need to reduce the amount of oil vapor coming into the engine from the PCV.

I used techron a few weeks back for the first time and Have seen an increase in mileage after it ran through the car. The tank with the techron my mileage actually dropped a bit.

That’s why I tried it, was just curious , it cost 12 bucks shipped to my door. I love me some Amazon!!

Well, if it does anything please update us. Otherwise for 12 dollars you can get 5 gallons of gasoline which will go a long way towards improving your fuel economy.

Oh stop it, I was thinking there was some gremlins hiding in my gas tank that needed to be exorcised. I know there is fuel additives in the gas we buy now. There might be some radioactive material, left over chicken sandwich or some other items in that tank. I just gave my car an enema!

I think for the price you paid, the additive isn’t worth it. Buying a quality gas at the highest octane rating you have available to you is probably going to be less expensive and just as good for your car.

Fuel additives are chemistry. The fuel you buy was processed by petroleum engineers and the additives were planned as part of the chemistry.

When you start pouring in aftermarket treatments (gas or oil), you are modifying the chemistry that you paid for in the gas or oil you bought.

Assuming that you can choose a random additive and improve the performance of your gas or oil is usually a mistake. There are some additives (Techron comes to mind) that have a good track record, but they are few in number. Most additives that actually work are best used to address specific, short-term problems, and then should be discontinued.
