Hey guys,

so I just learned that putting Supreme (91-92 octanes) in my RA '06 is not a good thing. What's done is done, don't flamme me. I would like to go back to 87 octanes after 2 years and a half on Supreme, but I would also like to clean contaminants from left over of the Supreme. I was wondering if it would be useful to buy some additives cleaners at Canadian Tire to clean the injectors and the fuel system. I'm talking about additives such as this : http://www.canadiantire.ca/browse/pr...08474396673439

I would empty my actual Supreme tank, fill it up with 87 octanes and put 1 bottle of injectors cleaner and 1 bottle of fuel system cleaner.

I don't wanna mess my RA and I think cleaning it to make sure there are no carbons left over would be nice. Also, I would ride it hard in order to get the carbon out.

What do you think ? Any advices before I attempt this ?

Thank you,

Neo

 

Just run a can of seafoam through a full tank of gas. I doubt you did any damage, though, you just threw away a bunch of money. You certainly wouldn't have harmed anything in the fuel system. Merely has excess exhaust and maybe some extra carbon built up on the exhaust valves/channels.

 

you're talking about this ? http://www.seafoamsales.com/motorTuneUpTechGas.htm

Would it be useful to put in the oil crankcase ?

 

^There is a list of canadian dealers on the "buy" page

That's the stuff, but if you're on top of your oil changes, you don't really need to put any in your oil. That's more for people who don't keep on top of their oil or use ****ty oil. Really, the best way to clean deposits/carbon buildup with that stuff is to VERY CAREFULLY pour about 1/4 cup slowly into the PVC line that feeds into the intake manifold while the engine is running. There are instructions on the can for this. Do it outdoors, as your car will smoke like crazy while you do it.

 

thanks I don't think I'm ready to clean that deep yet but thanks for the information

I got a Carquest dealer near my home, I'll drop by this week. (thanks Fifty )

Any other recommendations ?

ok I got mixed instructions. This video^ they tell you if it doesnt stall to then kill it. But some videos say to keep the car running while it takes all the seafoam in. Hydrolock is my only concern on this.

 

thank you !! video is always better than text

 

The video shows the incorrect way to do it. You should NOT stall the car, that means there's too much liquid in it and you're risking hydrolock. The proper way is to stick a funnel in that vacuum tube and slowly pour a bit of seafoam in, bit by bit. If you need to, have a friend gently work the throttle (low rpms only) to keep it from stalling. There's instructions on the can.

This video shows the proper way to do it. Any vacuum line that goes directly into the manifold will work.

Also, if you do this, don't forget to change your oil soon after, about 500 miles later. You don't want to leave this stuff in there.

 

can I do that way before 500 miles ? My next oil change isn't before 2500km by the way. I'm planning only in the fuel tank for now (1/2 or 1/3 of the bottle).

 

Fuel tank isn't a worry. Just dump in a full can at the gas station just before pumping gas into the car. None of this 1/3 can pansy crap.

 

thats what I figured, thanks for the information!

 

How in the world would running a higher octane hurt your car? The higher the octane the better irregaredless if you are bissted or not.

 

Was thinking the same thing.....^^^^^

That means I should call a Priest to exorcise the car and then pour some holy water down the PVC for running 93 octanes for 3 years and a half?...COme on

Just take care of your car, mantain it with good quality products and she will be very thankful

 

The debate on the issue is whether it creates more carbon buildup due to lack of complete combustion on engines that don't require higher octane. I think the risk is minimal, if not non-existant.
