I've got some Seafoam that I use for my four stroke, but I was wondering what would happen if I poured the rest of the can into my MC gas tank. I don't have an MCS so I don't have carbon issues. Would the Seafoam just act like one of those old school STP treatments if poured into a full tank of gas?

I take lots of short/er trips, only occasionally driving for an hour or more on the highway.

 

I use seafoam in my Land Rovers Fuel tank one can a month. It has helped keep my fuel system happy for the last 8 years. No issues or complaints, I can't say that it has improved anything statistically, but I can say I haven't had any fuel related issues.

 

As I have posted here before and have had no issues relating to the *carbon build up*(an '07 MCS w/47,500 mi. hwy/city) I use techron plus every 3000 mi. or so and Shell V=Power 93 oct. and run it on the highway hard once a week.The engine still purrrs.It has worked for me....... But I also change the oil between 3-5000 mi. too

 

OK, I'm going to be a dummy, but -- where in the heck does one find "Seafoam"?

I've asked the local auto parts guys (Advance, and Autozone and they looked at me as if I had asked for chocolate cake icing.

Is is something folks get online?

 

I've bought it at both Advance and Autozone.

 

If you have a second generation Mini it does no good in the gas tank as far as carbon buildup, the big problem. It may, and I say may, help keep injectors and lines clean, but with the high ethanol content, they stay pretty clean anyway.

Now on port injection, throttle body, carb, it may do as it is intended. I prefer Red-line or Chevron myself. Only by habit, not by any data. The whole issue in DI engines is the fuel does not spray on the back of the valve to clean it.

 

I usually get it at Pep Boys, but the last few times they've been out of the simple one-pint cans.

You have to be careful to get the right stuff - there's also a Sea Foam "Trans Tune" transmission fluid additive and a Sea Foam "Deep Creep" lubricant/penetrant, neither of which is what you want for engine cleaning.

There's a Sea Foam Spray which is just an aerosol version of the regular Sea Foam liquid, so it would work as well.

 

I have a second gen, but it doesn't have DI. Only turbo models have DI on the R56.

I was thinking it wouldn't hurt either, and might do something with fuel injectors. Just wanted to make sure it wouldn't do anything negative.

 

Justa is port injection? Might explain their much lower frequency of repair! No need for a vapor separator either.

 

Am I correct in thinking that the 2010+ turbocharged motors are also port injection? I had heard that was a change this year along with the variable valve timing.

 

Incorrect in thinking.

But yes they did add dual vanos, instead of single. (variable on both intake and exhaust side)

 

Thanks for that information -- it seemed like a lot of change to the turbo motor all at once. If they could just get the HPFP issue fixed, I'd feel better about being in line for an 11 "S".

 

Walmart. Also can try calling marine suppliers.

 

How do the neighbors react when you do a treatment? Does the smoke take over? Are the treehuggers going to call the cops?

 

That's why you should do it at night. The smoke doesn't smell too good and I sure wouldn't want to be enjoying a nice sunny day and all of the sudden smelling that for 10 minutes.
