Fuel additives

I use Lucas Diesel T. once every 25k miles or so to treat injectors. No much performance improvement on mpg noticed, but injectors over 1 mil miles are still sharp.

 

I use Power Service year round. White bottle in the winter, grey in the summer, and keep a bottle of 911 in the truck in case of gel emergencies.

 

Water in diesel is way way more common than you think. And it's everywhere. I install water traps in the lines and on the tanks. I've tried everything on the shelf. I think the little white bottles for water remover help but nothing completely works in removing water.

 

I use something completely different-

I Use Marvel mystery oil once every 2 months- A Gallon per tank

Why?> What is marvel's Mystery oil?

It's Different than your typical additives- Its an ABRASIVE that Scours the fuel system almost like a Drain Cleaner-

I Swear by it- Never lost an Injector and never had a Miss or rough idle since I started using it.

 

Farm & Home, Tractor Supply, Menards & Wal Mart will usually have a sale on fuel additives. Check their web sites for their ads. Saves driving to see what brands they may have. Typically the same brands as the truck stops, just at half the gouging price of the t/s. Then there is the online or dealer rep'd brands like Schaeffer & Amsoil.

My right tank always ran slightly lower than the left(Peterbilt). Am assuming it was the plumbing between the tanks at the cross over valve. Simple lesson was to never let the right go much below 1/4 tank.

 

Crown of the road will cause that.

 

According to a mechanic I once paid for something:
With Volvos, if it starts getting hard to start, it could be an injector issue.

When started, open up a fuel tank. If the fuel is bubbling, it's an injector issue.

Before hard starts start, run some automatic transmission fluid in each tank- about half a gallon to 100 gallons of fuel. Helps clean injectors.

^ Also according to mechanic.

 

On here search fuel additives. Plenty of info there.

 

Running lubricants that are not intended to be burnt causes deposits on nozzle tips. Sure lots of people used to do it, including myself doesn't make it right.


I run an old clunker, and believe in marvel mystery oil myself. I also throw some 2 stroke oil in almost every fill up.

Any additive is a preventive measure, if your seeing symptoms it's probably too late for mechanic in a can to do any good
