Redline Complete Fuel System Cleaner SI-1 Review

Update #1 May 30, 2015
Added 220 ml of Redline SI-1 to 49.72 L of Caltex 92 with Techron. Odometer at 111,753 km.

Update #2 Jun 9, 2015
Added 220 ml of Redline SI-1 to 49.47 L of Caltex 92 with Techron. Odometer at 112,480 km.

Adjusted fuel received adding 0.22L as SI-1 was added to total vol.
Update #3 Jun 19, 2015
Added 50 ml of Redline SI-1. Odometer at 113,166 km.

The medicine bottle (material HDPE - High-density polyethylene) holds well and does not disintegrate.


Since Techron is priced out of my budget, i decided to try and review this product.

Redline SI-1 has the same PEA that removes carbon built up but concentration may vary from Techron.

I am not sponsored by the product manufacturers. 
I share what works with evaluation of actual results.

First drafted on May 24, 2015

Price wise the 15 fl.oz (443 ml) Redline SI-1 Complete Fuel System Cleaner is priced at S$16~17.
The 12 fl.oz (354 ml) Techron Concentrate Plus Fuel System Cleaner is priced at S$21.80.

It is a gain of 89 ml and savings of $4.80, why not for the budget conscious.

Redline SI-1 has Polyether amine (PEA) which is the ingredient for removing carbon.
In the 2013 MSDS, the PEA content is reported to be 30~39.9% by weight. MSDS Redline SI-1

In 2008, the PEA is reported as 30 ~ 50%.

Attached link is the working of PEA. Tech Info SI-1

1. Keeping the valve cleaning continually; and
2. Further removal of carbon from the piston crown.

My fuel of choice will still be the Regular Caltex 92 with Techron.

The cleaner will be added after about 5,000 km of fresh oil change and i will do an oil change when the oil spans at 10~12k km.

Total bottles used = 2

Bottle ONE

I will do 2 x 1 bottle half doses @ 220ml each for the 1st and 2nd tank refill.

Bottle TWO

Thereafter i will dose 50 ml for every tank, about 9 times.
This will last till my next oil change as you can see in my illustration below.

(Assumption my vehicle refills every 600 km @47 L of fuel. Figures may vary.)

First half bottle dose @ 5,000 km on May 30, 2015
Second half bottle dose @ 5,600 km on Jun 9, 2015
Maintenance dose#1 50 ml @ 6,200 km on Jun 19, 2015
Maintenance dose#2 50 ml @ 6,800 km
Maintenance dose#3 50 ml @ 7,400 km
Maintenance dose#4 50 ml @ 8,000 km
Maintenance dose#5 50 ml @ 8,600 km
Maintenance dose#6 50 ml @ 9,200 km
Maintenance dose#7 50 ml @ 9,800 km
Maintenance dose#8 50 ml @ 10,400 km
Maintenance dose#9 50 ml @ 11,000 km
Oil and filter change @ 11,600 km, << Evaluation by boroscope and comments

I do not evaluate the PEA straight after one tank because i believe it works best over time, allowing the additive to sit and soak onto the carbon rather than running it straight at high revs or on ONE long drive.

Also, i believe the dose of one 15 fl.oz (443 ml) bottle is too strong and to be on the safe side, i prefer to under dose. Also i know that my valves are already clean through the boroscope evaluation previously that my valves are already quite clean from the use of Chevron / Caltex fuel dosed with Techron and my previous use of Techron Concentrate Plus.
(Again, it is a pity it is priced so high compared with the US)

How i arrive at the maintenance doses
I aim for conservative maintenance doses

Recommendation 15 fl.oz treats 100 gal fuel

where 15 fl.oz is 443.6 ml : 100 gal is 378.54 L

Calculated >>> 1ml : 0.8533 L

For my vehicle, i pump between 47 to 50 L, hence my doses would vary between
53.0 ml : 45 L
58.6 ml : 50 L

But for economical and usage purposes, i will portion to 9 doses for 1 bottle of 15 fl.oz cleaner at about 50 ml per dose. I dosed it lower than the 58.6 ml as the fuel already has minimal amount of Techron.

8 dose portions @ 55.45 ml ea.
9 dose portions @ 49.28 ml ea.

I will update this post as and when i do the pours.

There is little or no benefit from using the 98-octane grade

Lower-grade fuel still the top draw

MOTORISTS are sticking with lower-octane petrol despite a drop in pump prices in the past year.
Industry figures showed that 92- and 95-octane fuel accounted for 66.3 per cent of the total volume of petrol sold last year.

In the first quarter of this year, that share dipped to 65.5 per cent - but this was comparable to figures in 2012, when petrol pump prices ranged from $2.11 to $2.51 a litre before discount.
Petrol prices have been sliding since then. In January this year, before the Government raised petrol duties, petrol prices ranged from $1.75 to $2.24 - their lowest in six years.

Now, they hover between $2.15 and $2.75. This is largely due to the higher petrol duties, which were jacked up in February by 15 cents for non-premium grades and 20 cents for premium grades.
Crude oil prices have also risen since, with the Brent now trading at around US$66 a barrel, up from US$55 in January.

Industry watchers expect the consumption trend to remain in favour of lower-octane fuel because motorists now realise there is little or no benefit from using the 98-octane grade here.

This, however, was not the case 10 years ago. In the mid-noughties, 92- and 95-octane fuel accounted for less than 45 per cent of the market. Before 2000, their share was merely 20 per cent or so.

Businessman Leslie Chia, 50, said he uses 95-octane fuel for his cars, including a Maserati.
"Contrary to what people think, there is no need to use 98... My mechanic at Hong Seh (Maserati agent) says 95 is good enough," he said.

"It is only when I go to Malaysia that I pump 98, but that is because foreigners are not allowed to buy the lower grades there."

Automobile Association of Singapore chief executive Lee Wai Mun said: "You don't need to go for 98. In most countries, they use 92. Singapore's terrain is quite flat, and you don't need the extra boost to climb steep inclines."

Independent oil industry consultant Ong Eng Tong said: "High-octane fuels have a higher benzene content. Benzene has been linked to serious illnesses, such as leukaemia."

That said, Singaporeans are still resistant to using 92, the lowest octane, which makes up less than 7 per cent of sales. Observers cite the relatively small price gap between 92 and 95 (four cents a litre).

The gap between 95 and 98 is at least 20 cents.

Boroscope the pistons & valve. Review spark plugs and injectors.

Update May 21, 2015
For my purchase of Techron from USA and due to classification of fuel system cleaners as dangerous cargo, it cannot be shipped into Singapore via normal courier.

Hence the use and review of Techron Concentrate Cleaner fuel system cleaner will deviate.

Update Jun 23, 2015
I am now reviewing the Redline Complete Fuel System Cleaner SI-1


Dated: May 15, 2015
Vehicle age: 7 years
Odometer: 110,775 km

First for convention purposes, i will count the unit #1 from left to right (near the spark plugs and exhaust manifold)

This is for record keeping and comparison for the use of Techron with PEA cleaner usage to decarbonise the engine parts.

One other concern is that the Cleaner must be Oxygen and Air/Fuel sensors safe.
Contamination of these two sensors will upset the fuel economy altogether.

Also, the BMW cleaner is the Techron Concentrate Plus. So i am giving it a try.

The last time Techron was used: 
6844 km ago @ odometer position 103,931 km

For convention purposes, the positions are numbered in red
Motor Photo for illustration only

A. Here is the view of the Pistons seen through the spark plugs

Piston 1 is at top dead centre TDC position - no photo

Piston 2

Piston 3

Piston 4
The carbon bits looked soft, and perhaps easily removed over time.

B. Here is the view of the intake valves seen through the fuel injectors

Valve 1 viewed from piston space

As seen, the areas where fuel is sprayed, it has a clean aluminium surface.
Valve 1 viewed from Injector port
Valve 2 viewed from Injector port

Valve 3 viewed from Injector port

Valve 4 viewed from Injector port
Still waiting for the stock of Techron to arrive from USA.
The recommendation was to dose every 5,000 km

C. Review spark plugs and injectors

The NGK ZFR6K-11S is clean and dry, which is good.
As threads were previously applied with anti seize compound, it was easy to remove.

The tips are in very good condition after 25,183 km (after about 1 year)

Model:     NGK ZFR6K-11S 

The injectors have a bit of gunk similar to the deposits found in the combustion chamber space.

Dose of Techron in fuel vs manual dosing of Techron Concentrate in fuel

This piece of nugget of information is quite informational

The manual dose of Techron Concentrate plus is 16 time stronger than the dose in ready sold fuel.

You can read about my trial of Techron here

Ready sold fuel ratio 1 oz : 16 US Gal (1 ml Techron : 2048 ml fuel)

Techron prescribed dose 355 ml to 45 L (1 ml Techron : 127 ml fuel)
   12 fl.oz for 12 US Gal of fuel
   12 fl.oz is 355 ml, 12 US Gal is about 45.42 L

2048 / 127 = 16.1259842519685 times

The following below information is found on amazon's review

on April 9, 2012
Size: 20 Ounce
It appears that Chevron Techron works in some engines and not in others. Claims that "It doesn't work" or "It is a fraud" are absurd and should be dismissed out of hand. Sadly, on the other end of the spectrum some folks lead one to believe Techron fixes everything and that too is hard to swallow.

In my own experience using Mexican Pemex Magna grade for tens of thousands of miles, my Mitsubishi 3.0L engine gradually becomes obnoxious. Rough idle which vibrates the rear view mirror, hesitation, and stalling. Highway mileage becomes a joke; down from 28 mpg on the same route used dozens and dozens of times, to 22. A full tuneup from spark plugs, to rotor and cap did nothing except waste my time and money.

Three times the degradation occurred and three times I managed to find Techron (At Costco Warehouses in Acapulco and Morelia). I added one bottle to 16 gallons of Magna and it did not work immediately; it took almost 100 miles of highway driving for the engine performance to start noticeably improving. But improve it did and the original crisp throttle response returned, the idle roughness took a hike and mileage returned to 28.

I sure wouldn't buy a carton of six to try it out, but let's face it, with the cheapest gasoline at close to four dollars a gallon in the USA and three dollars a gallon in Mexico, a tryout of Techron is going to cost about the same as a double burger meal at a fast food joint.

A chat with a Chevron engineer revealed Chevron refineries add the eqvt of 1 oz of Techron per 16 gallons in their regular and premium gasoline. When i am in the states and use Chevron gasoline I do not need Techron. It would be a waste of money.

I've blown the same amount of money or more (than the cost of a bottle of Techron) too many times on an admission ticket to a bad movie. I sure didn't march out and dial up the director and complain. But I'm sure as heck not going to pay to see that movie again.

Try it. If it doesn't change your car's performance, at least it'll have blasted a lot of carbon out of the cylinders. But I'll bet that happens in only a very small percentage of trials.


From Caltex site, Techron Concentrate dose is 10 times more than Techron in fuel

Drum brake and shoe wear tolerance

Its only 0.5 mm both sides for the drum to wear down from 200 mm to 201 mm

As for the shoes it is 2 mm for replacement

Disc brake job, eliminate squeals & size slider pins

Tools needed
Spanner No. 14
Spanner No. 19
Anti Seize Compound
High Temperature Silicon based grease
Brake cleaner  /Contact cleaner
Thread lock (if available)

Step 1 
Crack wheel bolts, lift vehicle on jack and remove wheel

Full lock wheel to gain access to brake caliper bolts.
Use spanner #14 and #19 

Step 2
Remove the brake pads. 

Pads are easy to know when to replace when the brake wear indicator gives off a high pitch shrilling noise when it touches the rotors.

Crack open caliper frame bolts, spanner #17

Step 3
Disassemble brake caliper frame, slider pin, pads holder.

A thing to note about the slider pins.
The top pins are round
The bottom pins are faced at 120 degrees.

Photo Left
Top slider pin (part no. Pin B 45262-S0K-A01)
Diameter: 10.63 mm

Photo Right
Bottom slider pin (part no. Pin A 45235-S0K-A01)
Diameter max. 10.80 mm
Diameter min. 10.64 mm

The bottom slider pin is bigger than the round top slider pins.
Seems like it is designed to hold the grease in place.

Step 4
Clean out the slider pin housing.

The measured diameter of the slider pin housing is 11 mm.

Initially i was concerned that the slider pins had too much play in them.

But i figured out that these pins must hold adequate silicon grease.
Add too much, the pins cannot push in because of airlock.

When enough grease is in, the pins do not play as much.
This is the damping effect.

Tip: Use a thin, clean, long stick to apply grease into the holes.
Coat the slider pins with grease and assemble after cleaning.

Slip the rubber boots back into the caliper housing.

Step 5
Check rotor wear against manufacturer specifications.

Rotors have wear  tolerance specified by manufacturers.

My measured thickness is 23 mm

In our case, it is written:
Rotor standard size: 23 mm
Rotor replacement <= 21 mm

Data taken from Brembo 09.A455.14

Assemble brake caliper.
Coat the pads ad holder with anti seize paste.

All bolts must be bone dry when assembling.
Do not apply grease.
If you wish, thread locker can be applied.

Test brakes before journeying out.

Photos from the past - Sludge motor

This set of photos were from last year 2014.

There was severe oil sludge build up found in the motor.

Just to say that all is not lost, just needs a lot of love and tender care, the motor returns the favour surpassing 700 km.


There were a lot of varnish and sludge. 
I did what i could without allowing the bits to drop further into the crankcase.

You can see a lot of thick oil sludge here. I soaked these in solvent but it did not go away easily.
It had to be manually removed. I doubt engine flush would work for this.

It was a gung-ho attitude to remove the rocker arms and cleaning them individually.

In the process of removing, i thought i lost two rocker arm lock pins for the VTEC actuation.

The pin is for the VTEC actuation, to lock the normal rockers. 


Washing in solvants did not remove the varnish.


It is actually therapeutic to touch the motor and D-I-Y yourself.
