February 12, 2006Ive seen the stuff in a bottle you put in the gas tank that cleans the carbon out of your engine, but it was only for 4 and 6 cylender engines. Is there anything out there for a V8?

February 12, 2006You should'nt need to pour any chemicals into the motor with today's gasolines.
There are very few if any liquid fixes for serious engine troubles...
February 12, 2006If you're only cleaning injectors, I'd use Techron from Chevron. You can buy it in a bottle at stations or at places like Costco. They also put it in their gasoline. As jimco said, many brands of gas contain detergents and so you won't really need much a cleaning with modern gas.
If you want to clean crankcase and/or your intake, I'd use Seafoam. I have had good luck with it.
February 12, 2006Socal94 beat me too it. Techron is the best stuff on the market. It is expensive but apparently it is the only one that does the job right the first time in one tankfull.
April 22, 2012I`ve heard of a carbon cleaning system (machine from the outside) that somehow cleans the vavle & seat deposites without removing the heads. Anybody heard or used this process? Is it worth the $100 I`m quoted? Just curious.
