The efficiency of modern engines burning modern unleaded gasoline means that engines don't carbon up like they used to. I pulled the heads off of our nine year old minivan (with an engine that isn't any where near as efficient as the R18 and K20 Civic engines) this last summer when the engine had well over 140K on it and there was virtually no carbon anywhere, just a thin surface layer, and I mean real thin.BigT said:I guess it depends on how dirty your engine is. If you have an engine with 150,000+ miles on it and you run a whole bottle through pretty concentrated (like putting a whole bottle in a gas tank with only a couple gallons in it) it could loosen up a lot of carbon and other build-up which you wouldn't want to leave in your system.
But if you have a newer car, or a car which has had high quality gas run in it and maybe even injector cleaner occasionally this shouldn't be a problem.
maybe you should pull out your spark plugs and look at them.shipo said:The efficiency of modern engines burning modern unleaded gasoline means that engines don't carbon up like they used to.

if we are burning gasoline then no matter what there will be carbon.shipo said:The efficiency of modern engines burning modern unleaded gasoline means that engines don't carbon up like they used to.

Did you even read my post? I said I pulled the cylinder heads off, and last time I checked, cylinder heads usually include the spark plugs too (at least for gasoline engines). Like I said, that engine had over 140,000 miles on it and there was virtually no carbon buildup.iknowmysh1t said:maybe you should pull out your spark plugs and look at them.
