i recommend Seafoam. best stuff i've used/seen. follow the directions. you can use it in the tank, in the crankcase and through the TB. check it out at your local parts house.

I'd imagine you can...especially if you guys have Autozone's there as that's where I get it (bout $5 USD can). I've used Seafoam before...works pretty well...but be warned, some people's Daks smoke like hell when you run it through the tb. So if you live in a residential area, just be warned you may piss off the neighbors for a few minutes. haha
Here's something else I've been thinking bout doing next time I change my oil.
-----
Kerosene engine flush...Step by step...
1. Drain oil except one quart, or you can drain all the oil and add one quart of new oil. (starting with a NEW oil filter is recomended).
2. Add the remainder as kerosene, approx. 3 quarts.
3. Start the engine. DO NOT REV THE ENGINE
4. let it run until warm, not HOT, just warm. About 5-10 mins.
5. Drain the entire contents.
6. Add one quart oil, 3 quarts kerosene.
7. Run the engine again until slightly warmer. DO NOT REV THE ENGINE
8. Drain the entire system.
9. You can pour Kerosene into the NON-running engine as it drains out untill it comes out clear.
10. Pour about one quart of oil and let it run out of the oil pan.
11. Add your favorite oil/oil filter.(replace oil pan plug...:razz:)
12. Run engine until its at operating tempature. Check to make sure it is running ok.
13. Optional...You can drain the system one last time and add new oil filter and oil...
This does a great job...
The residue that comes out should be quite black and a thin liquid...Chunks or sludge should be disolved...
Note:
those who use Quaker State oil may experiance chunks and or sludge when draining the system through out the procedure...This is typical of Quaker State oils...

I've heard of using kerosene, but it really doesn't have enough oil for me, I'm not sure I would want to try that myself, there are too many other products on the market made to do just that. Plus the cost of kerosene, is pretty high these days.
Good LUck

Just remember ..... you might wash some gum/crap buildup that has been filling a worn seal or leak. Go too far in your cleaning might result in leaks that need fixing ....

That is actually brought up in the main discussion I linked to...most of those folks don't recommend doing it on higher mileage vehicles in order to prevent that from happening.
Also dakota49...according to the full discussion most of those other products are basically kerosene. If you only read what I posted, I'd suggest reading the full discussion...it contains a lot more info/answers to worries that people have. I sat through reading up on it one night. Dunno if I'll try it though...hoping to trade my Dak in within the next couple months and if I do, I'm not gonna bother. I'll just change it like normal.

GB2000 I did read the entire post, the difference is, if you use one of the products intended for cleaning the gunk out of an engine, they don't recomnd filling the crankcase with the stuff, just add any where from a 1/2 quart, to a full quart. That's a lot different than dumping 3 quarts in. However I do think it would work, though I'm not going to try it, I only have 16000 on my rebuilt engine. I use synthetic oil, and run it till it gets up to operating temp I think that helps fight the gunk.
I do appreciate the info though.
Good Luck

it would be faster to get services done at a local shop that does them.
look for a shop that does engine flush (I've posted about this many times, just search). Alot of shops do air intake cleaning (some even use seafoam in the machine).
Then going foward you can use products as a preventative measure.
