Fogging an engine due to corrosive fuel
 

Hey guys, anybody that runs VP fuel knows its corrosive property's . Does anybody that runs it and pays attention to this problem have a solution for keeping this from happening? I know fogging helps, I've used marvel mystery oil for long term. What do you guys like to use? Does it help? Thanks in advance.

I don't. Ive been told it can cause pitting on valves, seats.etc. I doubt that adding MMO to your fuel, if thats what you're asking, would pass fuel check though.

marine/boat enging fogging products sprayed down the carb while cranking the engine over with the ignition OFF for about 20-30 seconds then remove each spark plug and spray into the cylinder and crank over a couple seconds replace spark plugs you should be good to go

I use MMO, with the engine idling I use a shampoo bottle with the little flip-up thing on the cap. Engine idling, dribble it into the idle air opening in the throttle body. Sucks it right in, continue until it smokes. Makes a good bit of fog next time it is started. The smell tips off what it is.

Also, as an added note, If you have an engine that has sat for a long time or outside in the trailer all winter, it's a good idea to fog the engine (we use an air /siphon gun) w/ MMO 24 - 48 hrs BEFORE trying to turn it over, also remove the plugs and spray / blow around in the chamber to coat everything. Turn it over by hand several times before using the starter and good to go.

Like others have already said, I have used MMO in my stocker, and my alky motor bracket - 10.90 cars for years. If storing for long periods of time (winter), would mix some MMO with a little gas, and actually put in cell (I pulled foam out first) and ran it thru pump, lines, to motor. I just put enough in to get it all the way thru lines to motor. When it smokes good, it is protected. I normally pulled plugs and put some WD-40 in cylinders also. Usually changed plugs after... not sure they needed it, just did it.
On alky car, I would spray thru carb after each race, both into vents and into mouth of carb. I tried some of the "fogging" sprays, but WD 40 seemed to do just as well for me. Stopped the "white death" from alky, and no corrosion issues seen.
Would just run some gas thru cell before going to track, and while warming up car, before first pass. Never had any fuel check issues with NHRA or IHRA doing this.
good luck,
Ken

This stuff is fantastic. Just spray it down the carb with it wide open and crank it over with the starter. It can be found at just about any marina or Advanced
auto has it also and even seen it at Wally world...I use it after I am done for the weekend of racing..
