Are there any good fuel treatments out there that are actually worth the money? I’m not having any fuel related problems….but I would like to see if there is something out there that would help to clean deposits from the injectors and deposits from the valves/cylinder head. The car has 88,000 miles on it, so it’s not like it’s “low mileage”. I know lots of people that have had great luck with seafoam, but it seems like there are just as many who will tell you to stay away from the stuff.

I run BP 93 fuel in my 03' JCW MCS, which is supposed to have a good additive package in it that is supposed to keep deposits to a minimum…….but is there anything else I should dump in the tank every now and then just to give the fuel system a really good cleaning?

Thanks!

 

pick up a can of Seafoam at AutoZone. put it in your tank on empty then fill up. also you can put a cap of it in your brake lines to clean out your engine. all the crud, if any, will come out your exhaust system.

 

Should I change my blinker fluid and muffler bearings while I'm at it. I heard it will give me at least 10hp...is that true?

 

This should be interesting.......

 

Thought this may be a serious thread.

 

At the risk of making this a serious thread again, I use Amsoil Performance Improver (API) which is supposed to help with injectors, deposits, and mpg. I must confess that my '03 S has always seemed to run just fine, but I figured it was a good maintenance practice every 4000 miles or so.

 

Thanks for the info. And yes, this was intended to be a serious thread....but when I saw the first reply about adding a cupful to my brake fluid, I couldn't help with coming back with a snide remark

 

I've used Redline SI and Techron for years. The key is to wait till the last tank or 2 before your next oil change, fill a full tank of gas plus one bottle and drive down the entire tank. Refill gas, change the oil and filter. Done. I usually add Redline or Techron before a long trip.

Preferably the best way to clean out carbon deposit is highway driving at high RPM. City driving is less effective. Use 3rd and 4th gears and run the engine up to 4500-5000 RPM and let it sit there for a few minutes. Bounce off the RPM redline a few times if you're comfortable doing it. This is known as the Italian tune-up. Just make sure your engine oil is warmed up before hard revving.

I've started using Marvel Mystery Oil in small dosage... or "maintenance dosage". It's less expensive than Redline and Techron. It's been around for ages but some folks think it's a hoax due to its name.

I believe when the person was talking about brake lines, he meant the brake booster vacuum lines that run into the crank case. Not the actual hydraulic lines.

 

I had BG44K strongly recommended by a highly thought of independent BMW shop and have used it (product and shop) with no complaints. Any comments one way or t'other to help our OP make a decision?

(I worked really hard to be serious and nearly hurt myself)

This stuff is excellant, when I worked for a Independant Porsche shop this was the only cleaner we used, most dealers use it as a cheap tuneup, hard to find in autostores, but most dealers will sell it to you.

 

Mini usa sells relabeled chevron techron....
bg44k is good stuff....
Seafom if used right can do good stuff....have used marvel mystery oil on other cars with good results....
I thonk 90% of the additives/mechanic in a can stuff is usually just to make the buyer feel better....
But sometimes injector cleaner/etc can be warrented....they do have a time and place.
even techron says once evey 5000 miles....so constant use is not needed...if it is, than there is an issue.
much of what is sold is actually a light distilate oil...like diseal or jet fuel (think stp)...an old mechanics trick, just like using a bit of transmission fluid....not reccomended in modern motors with emissions controls....
