Which fuel system cleaner do you guys use, wanted to know which is the best fuel system cleaner that you all would recommend I use. Thanks in advance.

 

How many miles do you have?

Personally I wouldn't use any fuel system cleaner.

Maybe in that 80-100k range you may want to take it to the dealer to have the injectors cleaned.

Correct me if I'm wrong.

 

It's always been my belief that those additives do pretty much nothing as the gas you buy already contains enough additives to keep things fairly clean as you go.

I was interested in trying the Terraclean system a while ago but now I'm not so sure that that is just snake oil too.

I'm semi interested in trying it to see if it helps with my weird warmup idle and sometimes weird warm idle, but I figure I am just going to live with it until my next service and see what Lexus says about it first because it's under warranty and if there is enough carbon buildup to cause things to idle badly in there they ought to do a cleaning service like this for free to try to solve it.

 

Sea Foam, period. Best I've ever used. One in the oil crank case before you change the oil, one in the gas tank when it's near empty, and one in the vacuum line (watch the smoke exit the exhaust).

Google and youtube it. Stuff works

 

Seafoam seems a bit iffy to me. Too many anecdotal horror stories about it ending lower-tech engines, I'm not sure how I'd feel about dumping it into one of our DI engines.

I'd pay a bit extra and take it to the dealer to take care of it, just for the peace of mind that if anything goes kaput there or shortly after you have an escape route.

 

Cheveron for me every once in awhile.. Works in The ES..

Seafoam does work but your right I wouldn't put in a Lexus. I used it on my truck and had great results. But there are tons of horror stories but that's usually when they use too much through the Vac line.

 

I would just use octane boost that stuff really works. I used NOS and outlaw octane boost and it helped with throttle response.

 

gas cleaner?? just use Chevron with Techron lol.. n if you want more add some Techron concentrate.

as for injectors.. ive used Lucus injector cleaner before. I notice better MPG afterwards. but its not like mind blowing good.

 

are these additives safe for direct injected engines?? I used to use octane booster on my G35 and it made the car idle smoother and made it a touch more responsive ( could be in my head) but I have not messed with stuff like this on my GS because I am afraid to screw something up

 

No additive cleaners used by me, only Chevron gasoline used.

 

I usually try to stick to the name brand gas like Shell or Chevron

 

I've tried a lot
Shell V-power
Techron
STP
Marvel Mystery Oil
Store brand
etc etc

Never had any issues with them and the car continues to run great with great MPG so it surely isn't hurting it. Not sure of any true benefits outside of piece of mind and cleaner injectors.

 

i've got about 41,043 miles on the car currently and thanks to all above I've heard a lot of people that say chevron tech is a great product so I guess I'll try that out and see wat happens.

 

I've used Lucas products and always seemed to work well for me. Car runs a bit smoother with the fuel injector cleaner and there oil additive. But thats probably just a euphoria feeling.
