fuel additives to keep engine clean? - Tilted Forum Project Discussion Community

I've heard of additives that one can add into fuel so it helps clean the engine out. Are those any good?
I plan on doing a bunch of preventitive maintanence to my car soon and wanted input about the fuel system.

Thanks,
Robert

You can ignore most of the products you see advertised on TV, as the vast majority of them are junk. I'm assuming that your car is fuel injected? If so, I would suggest BG44K fuel injector cleaner. You may have to buy it online or at a local dealership as I'm not sure its sold to the public under any name brand distributor, but this stuff works AMAZING (is a bit pricey at about $20 a bottle). Its been somewhat of a "secret" for quite some time, but it worked miracles for RX7's tired rotary motor, and I was so happy with it, I used it on my strip car as well.

When I tore down my 355 when it was time for a rebuild, I noticed that my carbon deposits on the valves and piston tops had indeed been reduced. The only other "cleaner" type product I will use on my engines (only with a carburetor) is Marvel Mystery Oil.

Thanks!
I just did a search and found nothing but mentions of this stuff on forums. My car is a 99 Lexus LX470 with almost 50miles on it.

I had good luck with Rislone. You run a quart of it in place of a quart of regular oil, then change the oil about 1000 miles later.

My T-Bird had some valve noise when I'd first start it up. I figured it was due to sludge from the previous owner's poor maintenance/cheap oil. I ran some Rislone in it for a while, and that solved the problem. I've been using Castrol GTX and Purolator filters ever since. Now, 2.5 years and 30k miles later, I still don't have any valve noise whatsoever.

Here's one place you can order it online: Click HERE

I've bought two bottles locally, one from a Toyota dealership, and another from a Mazda dealership.

You can also get aquafoam IIRC it's called. Everyone I've talked to says it works great, not one complaint.

If you can find a BG distributor, have them run the complete system through there. It works all kinds of wonders.
