No problem - Yea , in that link Mag gives yuh a few different procedures to follow with Sea Foam. I'm contemplating it to clean my valves up.

I've also heard that a little "Diesel Fuel" , pre-mixed in your tank will clean things up as well.. BUT, your truck will run like chit during the process, just until you refuel. ..

 

Oil additives should not be used except to correct specific issues, the same generally goes for fuel additives unless you doubt the quality of your fuel. I've used both Seafoam and Techron in the fuel, and I prefer the Techron - Ford even approves its use.

Then again, the best fuel system cleaner out there is BG44K, if you wanna spend the big bucks.

 

I add a quart of Marvel's Mystery Oil to my '98 Expy every oil change (every 3,000mi). Over 142,000mi and haven't touched the engine yet. Gas mileage has remained exactly the same for years.

 

I like the Lucas Oil Upper Cylinder Lubricant.





Lucas Fuel Treatment is a fuel additive that cleans and lubricates your entire fuel system and upper cylinders. It delivers better combustion for more power and higher mileage with lower emissions. Lucas Fuel Treatment can be added to gasoline, LPG, and diesel fuel and can be used in two cycle engines. It contains no alcohol, solvents, kerosene, or anything else that would be useless or harmful to engines. Lucas Fuel Treatment is also known as an upper cylinder lubricant with injector cleaners.

Low sulphur fuel and reformulated gasolines have had the polymers removed from them, not because the polymers were harmful but because they were attached to the aromatics (fumes) in the fuels. In their zest to rid our air of gasoline and diesel fumes, our government has stripped our fuel of its main lubricants and, in the process, a great deal of its power.

Lucas Fuel Treatment replaces these polymers with a concentrate that makes the fuel slicker and more powerful than it was originally. In fact, the user usually picks up more than enough fuel mileage to pay for the fuel treatment itself.

Lucas Fuel Treatment cleans and lubricates valves, pumps, carbureators, injectors, and compression rings. It is an absolute must for rotary pumps! It extends the life of catalytic converters and raises the octane to eliminate spark knocks. Lucas Fuel Treatment safely replaces the need for lead in older engines.

Lucas Fuel Treatment is an excellent diesel tuneup. Before going to the shop with an engine that is smoking or low on power, we suggest that you try adding a half gallon of Lucas Fuel Treatment to every 100 gallons of fuel. This is often all it needs!

Lucas Fuel Treatment works by lubricating your complete fuel system and upper cylinders thus avoiding build up of harmful deposits. The additives in the treatment work to maximize the combustion process, thus providing mileage, power, and emissions reduction benefits.

 

You don't need anything extra in the fuel or crankcase. You really don't. The chemicals, cleaners - all the additives are already added in your automotive fluids.

The reason "Snake-oil" exists is because theres a HUGE market for it. They write stuff on a product and you like what you read. Most of the junk won't hurt anything unless you use to much of it..Your making all the snakes in the world very rich.

Just maintain what you have using fluids that these motors where designed to use and run on. That's all you have to do .

230,000 miles here and she's running great!!

 

Now that its winter I'll add some Iso-HEET Premium Water Remover and Fuel System Antifreeze to my tank on occasion.

i stay away from oil additives. Companies spend millions working on their formulas to get them right so don't mess them up with some $1 bottle of miracle snake oil.

Sea whatever and pretty much all "cleaners" are a scam. Change the oil at the proper intervals and don't do anything stupid like adding diesel fuel to your tank. You'll be just fine.

 

I called valvoline last year and asked a few questions about their engine oils, and if I remember correctly, their Durablend is 30% synthetic. Customer serv rep stated that their oils can be mixed and interchanged if needed because additives are compatible if not the same. He also stated that oil should be changed around 3k because additives dont last much longer than that so I guess they wear out or get used up.
