Is it worth using fuel system cleaners?

Hey all,

Wondering if it is worthwhile to use a fuel system cleaner, like the ones that get sprayed into the vacuum hose in the intake plenum and the ones in the fuel tank.

Regards

 

Probably more important is keeping a bottle of ethanol treatment in the boot and using it at every fillup.

 

Can you go into more detail please

There are better articles out there and probably better products but this hits the high points for you.

 

Interesting
Thank you

 

So Dr Tommy, do you use E10? I have been wary of using any ethanol based fuels. I use Shell Optimax. Please let us know of your experience with ethanol fuels....

 

Sitting is the worst thing that happens to injectors. If the car is a daily driver, don't worry about it. If it seldom gets driven I am not sure injector cleaner will be enough but it is worth a try.

 

I use Marine Gumout, but really as Brian says every time I fire it up I go down and add enough fresh gas, only a few gallons, to move the surface in the tank up, if only an inch or two....

Slosh it around!!!!

 

They soften every piece of rubber it touches, in the old carbed cars..

Big $$$ repairs.

 

I wonder what the K-Jet expert rebuilder thinks of fuel additives. (Larry, I think his name is?) He sees the guts of lots of systems. I bet he has an opinion and given his of work I'd be interested in what he thinks.

 

You can't find gas here where I live that isn't at least 10% ethanol so I have no choice.

I replaced all my fuel lines with the kit from David Helms a few years ago. I posted a picture of one of my fuel lines. it was in such bad shape it sprung a BIG leak when we were removing it. It was about to let go at any minute, I was unbelievably lucky.

I will empty a bottle of Techron about every third fill up. That is probably pretty safe because it is already in the gas to begin with if you are at a Chevron. I also top off the tanks before I park it.

 

There's an app called 'pure gas' that finds local stations with non-ethanol rec 90.

 

It seems like we're covering two different, but related topics: 1) If it's worth using an additive to clean injectors, and 2) What to do about E10 gas?

I can offer no comment on Topic 1, but for Topic 2, I can only pass on what was recommended to me when I purchased my 308 last year from Scuderia Rampante: I mix in a few gallons of AVGAS (100 octane) with the 90-92 octane E10 I get when I fill up. I guess it's to prevent/limit separation of the E10, but the AVGAS does have a lead content a little higher than the unleaded E10, so I'm concerned about deposits/clogged injectors (i.e. Topic 1). Certainly open to suggestions and advice!

 

A little bit of 2-stroke oil in the tank before filling up has the same effect as most fuel additives. It prevents the fuel system from completely drying out while not in use. I got this info from a K-jet expert.
