I got a free gallon, can it be used as a fuel additive for lubricity or is it a waste of time? ~Aaron

DON'T DO IT.

Maybe for your lawn mower, etc., but not for your PSD. Do a search in the archives, as there is a lot of reasons why NOT to do this.

 

[SyN]

Agrees with Tailgate. I myself only use FP60-Redline 85+ or Diesel Catalyst or Stanadyne. There are a few really good Diesel Additives, just don't add that Poison to your PSD.

Marvel Mystery Oil has been around for decades. I wouldn't be opposed to using it in an old pre-emissions gasser or diesel, but honestly, with the new formulations of fuels and the resulting design changes, I wouldn't use it in anything newer. I don't know that it will hurt anything as far as seals, o-rings, etc, especially since they are all reformulated, but why risk it? The only diesel additive I would be interested in other than the ones already mentioned would be some good old fashioned sulphur, but if you have a cat in your exhaust, sulphur will ruin it pronto.

Why take the risk? There are no documented benefits from using Marvel or Bardahl, STP or any of the old formulations in new engines. Same goes with TFP teflon- that HAS been extensively studied in independent labs and found to provide the company owners vast sums of money and zero additional protection for your engine. That research is readily available online.

Someone used in their PSD and it foamed up BAD. Which will cause it to miss etc.

 

[clamgulch]

Did they dump it in their fuel or the oil pan? Either way I wouldn't use the stuff, but I'm curious.

 

[gregrob]

Oil,

I'll try to find the post on it.

 

[gregrob]

Dang, there are a lot of posts about this stuff!
I can't find the exact thread, but the guy plainly said he added it to the oil, and the truck immediately ran like crap, he did a few things then looked at the dipstick and it was foamy, drained his brand new oil + MMO mix, replaced with fresh oil, problem solved.

About adding it to the fuel, isn't it dyed red like off-road diesel? Not a chance I would take /ubbthreads/images/graemlins/shrug.gif

 

[SyN]

Either Way! I wouldn't use it in a PSD.
Fuel or oil.

 

[elkkiller]

thanks guys, I guess I'll find another use for it. I usually use Stanadyne every fill up but the marvel was free. ~Aaron

 

[Pappy19]

Use a pint on fillup in the fuel and it won't hurt a thing. It's a good injector lube. I used it for years and old time diesel mech's used it for almost everything. But the main thing is for injector clean and lube and it works as good as anything else. It's a marvel.

 

[ProDriver18]

I don't think I would use it myself but I do know a guy who adds some to the fuel everytime he fills up. He has an '06 with, the last time I saw him, about 70,000 miles on it. He says he has run this stuff in every tank since the truck was new. /ubbthreads/images/graemlins/shrug.gif

Yeah, a "marvel" that anyone would use it in a twelve thousand+ dollar engine! /ubbthreads/images/graemlins/wink.gif

I'll pass.
