Hum Good,
Your getting good advice. Tell dealer thanks but, no thanks.
Sea Foam is great and there are some Lucas products that work well. If it was water only you needed to remove run a couple of bottles of HEET in a tank of fuel. I ususally do that in all vehicles twice during winter as condesation in tank is bad during winter. HEET is very inexpensive.
There are many fuel treatments for carbon etc. but, we have always run about a quart of kerosene or even diesel fuel in a full tank of gas every few tanks and they are some of the best carbon busters you can use. Learned that trick while in farming from all the old timers. One rule to remember is, it is OK to have a little diesel in your gas but, it is never Ok to have any gas in your diesel. Gas in diesel raises the the cumbustion rate creating severe detonation and will shoot a piston and rod through the bottom off the pan on a diesel rig.
Another thing i like to do is right before I change oil I put a full quart of kerosene in the oil pan and start engine letting it get to operating temp and if you want to keep a good clean engine, if you did this till 100,000 miles you would tear it down and every part would be shiny no sludge anywhere. There are places on every engine where sludge collects especially up i the heads.
Let engine idle only and do not put any load on motor letting it run for about 30 minutes after operating temp. is reached. I have actually used 2 quarts and drove the rig where there would be actual force pumping the oil getting the spray off effect but, then again i do many things i do not tell others to do. It is my money and my bad if something goes wrong. All the things i mentioned are things that i have seen old timers in the farming world do for as long as the 50 years i have been alive and could remember. So i recomene the safer stuff until you get a feel at it. i offer these tried and trued things only at eaach members own risk but, i do not shy from doing it and have donw it to every car and truck i have owned. Never had a motor go bad. Do not think I would use the motor treatments if your running synthetic oil as i will not.
Hum diesel in your gas I would not be concerned with as it is most likley helping you. diesel would only clean and lower combustion rate a little depending on how much is in the tank. Even if there is to much all it does is wet doen the spark plugs and kills the fire at the plug. So i do not think you have anything serious to worry about. I wish i was closer where i could see it for myself and i would give you a recommendation i would right it in stone. In farming we deaqlt with this stuff so much with fafrm hands always pulling up and filling tank with diesel even though by state code they are marked in huge red letters. I kept a lock on the gas tank though so that mistake could not be made on a small diesel $25,000 engine. It would be Ok until you dropped a 30' disk in the ground and the throttle was pushed wide open at 2500 rpm and about a minute later you would hear a whewwww sound if it only blew head gasket and you can imagine what you would hear if rods dropped and it always would be more than one.
Oh, well if anyone needs a good farm hand or ranch hand I can drive anything mechnaical and i can rope (with pratice again) ride hard, work cattle through the pins to doctor them with shots, dehorn, castrate the boys to make them steers hehehe, tag there ears, brand them, and many other things. I can be a fence rider stay in line shacks. In crop farming i can run the most up to date GPS guide tractors or combines. I would not mind doing that stuff again if pay was decent and fuel for my H2 was paid for and you were willing for us to build some kind of H2 monster I would be happy.
Oh. you could leave me in charge and all would be as good or better than when you left and your wife protected and not touched. I'm honest as the days are long and my hand shake means more than any piece of paper. All that is left when you die is your name and it is important to me that no one can associate anything bad with it and people will remember me for that reason than for all the things and money a man could have then never use it to help better others with.
OK off my soap box and finished my job application but, forgot to mention no matter what kind of company you got I can run it for you after a short time. I have run and do run well now others do for me, run several companies that have nothing to do with each other. I just been having an urge for new scenery and maybe new challenges with a reason to go there and do it. Maybe you just want to give me a position so i can do nothing but, think and design H2's with you etc. LOL
