Lavacon Posted August 12, 2011 Share Posted August 12, 2011 I was just curious if any of you use any fuel additives and if so which ones. I have always used Chevron Techron in my other cars and found that it performed as advertised. Does anyone know how this will play with a Subaru turbo engine?

cholmes1 Posted August 12, 2011 Share Posted August 12, 2011 It will be fine by my estimation. I have been using it in my Impreza for nearly a decade and no ill effects. It will have NO impact on the turbo if that is your concern as it is purely a fuel additive. The only potential issue I could foresee is if you run a low octane fuel thinking this will help 'boost' the rating. That will not happen realistically with this or any other product on the market. You might also consider not using it if you have an aggressive tune. Just my opinion. Link to comment Share on other sites More sharing options...
Lavacon Posted August 12, 2011 Author Share Posted August 12, 2011 Still stock, only working on suspension upgrades atm. I only run 93 fuel. I just use it to keep things clean. Link to comment Share on other sites More sharing options...

f1anatic Posted August 12, 2011 Share Posted August 12, 2011 Lucas oil upper cylinder lubricant and injector cleaner. I found it to work quite well without the stigma and potential ill effects of fuel additives. I really find it to work as advertised: smoother running and 1-2 mpgs Link to comment Share on other sites More sharing options...

apexi Posted August 14, 2011 Share Posted August 14, 2011 Water and ethanol, what are you talking about? Please elaborate on your ignorant attempt to poke fun at us. Link to comment Share on other sites More sharing options...
VermontGT Posted August 14, 2011 Share Posted August 14, 2011 1) There are very few stations in my area anymore that sell gasoline without any ethanol in it, which is a PITA for those of us with older/"classic" cars since the ethanol degrades rubber components in the fuel system. 2) An old albeit sleazy trick for gas station owners to make a little more profit margin was/is to add water to their holding tanks to dilute the gasoline while charging the same amount for it.

cbt299 Posted August 15, 2011 Share Posted August 15, 2011 I think i'm gonna pick up some lucas stuff. Link to comment Share on other sites More sharing options...
ChemicalWaste Posted August 15, 2011 Share Posted August 15, 2011 I've used a few of the Lucas products and honestly, I haven't seen a difference. Maybe that's a good thing. I like their booster better than other boosters though. Might not be good for cats. I don't really know. Injector cleaner as well: haven't noticed any issues with the injectors so maybe that means its working. Maybe that means I didn't need it. Seafoam seemed to help the most but that was minimal. I 'm becoming less and less a believer in mechanic-in-a-bottle crap though. I have read that the Lucas octane booster can raise octane levels up to 6 points but you can't believe anything you read on them internees.

05LGTLtd Posted August 15, 2011 Share Posted August 15, 2011 I run a shot of Techron every other OCI. Probably not necessary, since my car is only fed Shell 93, but have been in the habit anyway. All I need now is a hill holder and a center passing light... Link to comment Share on other sites More sharing options...
xero287 Posted August 16, 2011 Share Posted August 16, 2011 I use the STP fuel system cleaner every other oil change..? Link to comment Share on other sites More sharing options...
ChemicalWaste Posted August 16, 2011 Share Posted August 16, 2011 Maybe the reason I don't see an advantage using the octane booster is that I don't run it everytime. That would make for a $55 tank of gas. For me, that's just not happening. Maybe I'll start trying that now that it's not my daily driver anymore.

05LGTLtd Posted August 16, 2011 Share Posted August 16, 2011 ^If your not tuned for a higher octane, your not gaining any performance. You might gain a little knock protection, but a solid tune for the pump fuel you are running is better for that purpose. All I need now is a hill holder and a center passing light...

ChemicalWaste Posted August 17, 2011 Share Posted August 17, 2011 Right. I basically ran it to check if it would reduce the knock sum I was seeing just in case there might be anything going on. It didn't effect anything so it's probably just picking up random non-sense. It doesn't trip any feedback knock or FKLC so I stopped worrying about it and thus stopped using it. I don't do track days or anything so having it tuned for higher octane would be a royal PITA anyways. Link to comment Share on other sites More sharing options...

Exactly, additionally tuning or doing WOT tuning runs with any "cleaner" in your mixture is bad news. I ran the Redline cleaner in my 300 before a dyno tuning session, knocked like crazy. Emtpied the tank, refilled with a full tank of new Mobil 93 (still 10% corn) and problem solved. I'm also leary of "octane boosters". Toluene is the only thing I'd consider running for an octane booster, and even then it's useless unless tuned for it. Link to comment Share on other sites More sharing options...

My thought is, since I always run Shell 93 V-Power I am getting a decent amount of cleaners, true. But it's the same cleaners all the time. Every 7500 miles or so I throw in a bottle of techron to get a little "wider spectrum cleaning action". It's ~$7 and takes no time or talent. I'd say 49 of my last 50 fills have been Shell 93. The odd one was Exxon 93. All I need now is a hill holder and a center passing light... Link to comment Share on other sites More sharing options...
ShopTeacher Posted August 17, 2011 Share Posted August 17, 2011 I am personally not a fan of any "aftermarket" fuel additives, rather than add some who knows what to your fuel tank why not make certain you are getting premium fuel. Toptiergas.com lists the companies in the US that adhere to higher standards on fuel production, and if you always purchase fuel from one of these stations, you should not have problems. That being said every 30k I clean my injectors with a pressurized canister, use GM top engine cleaner to clean the carbon out of my engine. I am partial to GM top engine cleaner because I have seen what it does to stuck rings on Saturns, and it kicks butt. Link to comment Share on other sites More sharing options...
