Holy Moly, this stuff seems to work.

My gas mileage clearly improved. I was hovering around 15mpg for a while and it shot back up to 19mpg. I do not granny my RX-8 either and love to rev it.

I did not expect it to work and I've tried other gas additives that did nothing for gas mileage and at best just gave me peace of mind about reducing carbon buildup or going up an octane point.

What I like about Red Line additive was that its an upper cylinder lubricant and help cleans carbon build up (another Rotary engine issue).

I was never fond of the whole premixing 2-cycle oil path and was looking for a gas additive that was a lub and could handle carbon build up as well. The Red Line stuff might be it, but of course I'm curious about what others think.

Fire away!

I tried it either last year or the year before. Seemed to help.

Now this is a whole lot safer than the dumb acetone additives people have been talking about. Cleans, lubes, and doesn't melt your gas lines.

 

I used 2 bottles just couple tanks ago. (damn it cost me 8 bux each)

it seems to do *something*, at least I have better acceleration.

mpg wise - none that Im aware of.

 

Dude, 1 bottle is supposed to be able to treat 100 gallons. Wow! Maybe you flooded your engine with gas additive. I wonder if there is a point of diminishing returns. 1/4 of a bottle good, but 1/2 to whole bottle bad...

Also, what is your gas mileage like?

Maybe you are at MAX mpg for how everything is configured. I don't expect this stuff to give us like 30mpg. But if you are say already getting 18mpg to 20mpg, than you are doing well.

 

Redline SI-1 is an excellent fuel additive - Good cleaning with some added lubricity. SI-1 is a Polyetheramine (PEA) based cleaner with other oils/additives for it's lubricity.

PEA is one of the better fuel cleaning ingredients out there (developed by Chevron) - others with PEA include Chevron Techron and Gumout Regane, athough these do not have the lubricity characteristics in their formula that SI-1 has and is very beneficial to the rotary.

 

What exactly is it? Does it clean out the fuel system or something?

I should've been more *clear*

what I really meant was I used 2 couple tanks ago, 1 bottle *each* tank. not 2 bottles in 1 tank.

Im not crazy enough to try 2 bottles for 1 tank .... :P

but guess what ... I just got another 2 bottles today .... well, not for me, I think its time to clean my father's PoS 12 yr old mini van ...

 

Be careful, some vehicles use fuel injectors that are very reactive to additives, espically those designed to clean fuel injectors ironically.

What I am saying is that in the process of trying to clean them you will probably cause the injectors to fail because they will become very brittle and break.

 

oh the irony ..... those ironic cleaners work well ?

 

I tried some other cleaner on the mini van b4 but dont seems to do jack ....

I'll be careful, Thx

 

so is this additive better than Idemitsu premix fuel lub?

 

HuH ? this is an injector cleaner.

Premix is lube.

the heck ?

 

it is fuel lub that does cleans injector too so what is the difference? between fuel addictive and premix?

 

Fuel Additives in general are there to clean first - while most provide no lubrication, a few do provide some lubrication such as FP3000/FP60, Lucas UCL, Redline SI-1.

Premix is 2-cycle oil fuel additive (light oil w/additives) that is added to lubricate the rotor seals (or more in other applications) - with some cleaning agents added to help slow down engine deposits.

Different additives for different purposes - both are needed to the 8 to perform well over time.
