Just wondering if this was bad for the rotory engine. Probably not, but I figure 1) get an additional post credit 2) have some laying around and might as well use it... Thank...

 

I would'nt put that in my rx7. All it is is a mixture of solvents and cleaners, it's ok for a piston engine,but in a rotary you do not want anything in your fuel that might thin out the oil for the Apex seals, rotorhousings and side housings.
A rotary injects oil into the housings to lubricate the motor. You do not want to thin what is already not enough lubtication. To clean your injectors go to rockauto.com and send them off to be refurbished. If you are determined, Use Lucasoil injector cleaner and uppercyinder lubricant- mainly because it is an oil based cleaner. You should put a small bottle of 2 cycle premix in every fill up to pevent premature wear of the rotor housings. I use quicksilver from wal-mart. Good luck!

 

I use that exact brand once or twice a year....buy it on sale. Been doing it for years. Absolutely nothing wrong with it and "used as directed" it won't hurt anything.
A few years ago when I rebuilt my engine for a coolant seal failure I sent my injectors in to have them cleaned and flow-tested. From the before and after cleaning I gained less than 2% on injectors with 90k miles. So it seems to work. And BTW, my housing and hard seals showed no abnormal wear.
There are few other things that come to mind to maintain your fuel system that are inexpensive. Fuel filters every 30K or so. Changing out the fuel pump sock can't hurt either.

 

Thanks for all the information.

 

Techron goes in the gas, not the oil. Works as well as any other carb/injector cleaning additive. Sea Foam is a more popular gas additive on this board.

 

Cheapie 2 stroke Supratech from Walmart in your gas tank is probably one of the more helpful actions you can take to help keep everything nice and lubed up. Or you can go more expensive 2 stroke if it makes you feel safer. Research pre-mix. =)

 

Wait so a good maintance would be EVERY fill up? not every other or once a week?

 

I don't disagree. But the OP was actually asking about Chevron-Techron, which is a fuel system cleaner/injector cleaner. While it's a fuel additive, it's not a pre-mix lubricant...at least I assumed he knew that.

 

From what I am hearing. As a good measure, perhaps fuel system cleaner (once a month) and small bottle of 2 cycle premix at every or every other fill up (not both together)? Thanks again.

 

Sorry blue...I apologize as I wasn't clear. =)

I understood what he was asking for and didn't mean to come across as if I was negating your statement. Your experience certainly adds value (and saves money) for the OP as you have had success running cleaner twice a year vs monthly or what have you.

However, even if you have an OMP on your car my suggestion is to put a little premix in EVERY tank of gas.

 

Yes, it does go in the gas...which is injected into the housings....where engine oil is also injected for the purpose of lubrication and premature engine wear.
Common sense will tell you injector cleaners are able to clean because they have solvents to remove deposits which claim to clean injectors; along with thinning and cleaning that very trace amount of oil away.

 

Still alittle off the original topic, but I've been doing just that since moving to a PFC and new engine.... ~ .5 oz. per gallon.
OK. If it makes you feel better, let common sense also tell you to add one more ounce of pre-mix oil with a full tank of gas. You've now more than made up for the solvent qualities of a fuel system cleaner. And for comparision, you've also more than made up for it with Auxillary Injection (AI), since many also inject methanol and/or water. Methanol also has solvent qualities and is injected into the combustion chamber at FAR HIGHER RATES. AFAIK, there has NEVER been a report of adverse wear of hard seals, housings or irons traced to either.

 

Has there ever been any bit of independently verified scientific testing that shows any off the counter fuel additive is beneficial in any way?

 

Aaron asked a great question,is there any verifiable evidence? In my original statement I made the assumption that the OP does'nt add premix. Obviously I was correct as he is asking questions relating to that. I am also correct that the only right way to clean your injectors is to have them professionally cleaned and tested. We are speaking to someone who obviously does'nt use Auxillary Injection. Why are you making statements that do not apply to his question? No, It does'nt make me 'feel better' because I am right about the additive. I replied back that he should use a premix. Why are you making such a simple question so complicated with a pissing match? We know that you are smart, you dont have to prove it.

 

Now hold on there pilgrim,s . yall get to talking rough like and the next thing every one will be out in front of the saloon a wantin to draw their rotaries .. That,s my John Wayne Impression , Just in case you couldn't tell ,, What do you think hows the accent ?? IMO .. The so called fuel cleaners and injector cleaners no matter what brand should be left on the shelf .. I used carb cleaners before injection and I never , in way to many years remember any of the stuff making any difference to anything I used it on .. In the last 15 or 20 years I have bought and used different brands of these so called miracle additives and nearly every time I would end up with emission problems of one kind or another engine light coming on etc. Even my 6.5 diesel if I added any kind of system cleaner to that , the check engine light will be on with in 2 days and will not go out till the fuel is diluted a good bit .. I believe that these mixtures change the make up of the fuel making it burn at different temps with different emissions causing sensors to go off ..
I think the adding a tad of 2 stroke to the fuel might not help but should do no harm .. at the very least you might end up with a pound or two more compression and we would all welcome that .. Like I said just my opinion ,, Have a good one all Gerald

 

i use that additive in my supra with no issue not exactly sure how it would affect the rotary, try it and let us know how it turned out

 

Chevron uses Techron in all of its gasoline fuel.
Porsche and Mercedes sell the concentrate under a different label to clean injectors and remove carbon.
Early on most of the Detroit car companies shipped tectron fuel it in for their EPA tests because it was not locally available.
I have seen it stop a friend's knocking Dodge Dart slant six with one treatment (it also made the gas gauge start working again!).

But to be fair... I worked for Chevron as an Helicopter Mechanic/Sup
