I always use reg and once in a while use prem to "clean everything out"....is there a such thing or no?

 

Premiun doesnt clean anything. Addivites to the gas do. If it makes you feel good do it but it honesty is a waste of money. The only time higher octance fuel is needed is if your machine is experiencing "knock".

 

actually all gasoline comes from pipelines these days....and the additives are mixed depending who is selling the gasoline when the gas leaves the pipeline, sometimes this is in the truck. Higher octane does burn slower and is a waste of money if you do not need it.

 

This idea has no factual basis, simply another gasoline myth.

 

off topic but do those fuel injector cleaners for cars really do anything?

 

I use Seafoam quite often. It acts as a fuel stabilizer and also helps clean the carburator and combustion chamber. It is great stuff. I use it in all my engines from lawn mowers to truck.
