What additives do you use for your WVO?

[Marv]

I know it's been touched on in a bunch of different threads, but I don't think we've ever really had a thread discussing WVO additives.

Sounds like the common additive is Powerservice brands (grey and white bottles). Also, I believe Greasy brought up Stanadyne and Lucas additives.

I've been considering adding something to my WVO in an effort to boost fuel mileage.

So what are you guys running and why?

Have you seen any increase in performance/mileage?

Any adverse effects?

Thanks!

Marv- On the diesel side i was always hot or miss for me. I usually used the grey bottle dieselkleen though. On the WVO side, don't use anything but diesel. I have done some testing and have found that some of the standard off the shelf diesel additives actually promote polymerization at a more rapid rate thn the oil alone. However adding diesel to the oil at 10:1 practically eliminated any tendency for polymerization. Nothing supr scientific just my experiacne.

I haven't messed around with wvo additives at all, but I read FN's test re: diesel in WVO preventing polymerization and decided to increase my purge time on my V2 to around 8-9seconds just to return a little diesel to the veg tank each time I shutdown...

I have used nothing for both diesel and wvo for almost two years. Jason, do you recommend diesel for wvo side and might this cure my switching problems.

Interesting Jason, I didn't know that. My main thought was an additive to boost the cetane rating of the oil and hopefully boost my mileage. I use the Powerservice in my diesel now, but nothing in the oil.

Anyone else tried anything?

Which ones? I've been adding Power Service in the white bottle to my WVO. Should I forgo it the next time I fill up?

This is what we NEED.

I have used something very similar a friend mixed up and the biggest thing I noticed was how long filters lasted. (on truck and prefilters)

The anti-oxidants and chelating agents basically keep poly from happening. Polymerization begins loooong before you can see it, the increased viscosity seen early on is a symptom of larger molecular chains. These increasingly bigger chains begin to plug filters long before ya see any chicken skin stickin' to the sides of yer in-tank HE, etc.

Many of us have read about folks w/return fuel systems and looped systems who run the VO thru filter multiple passes. They invariably have short filter life. Why? They filtered it to .5 microns before putting it in vehicle, it should NEVER plug a 10 mic filter, no matter how many 'passes' - right? The answer is very likely early-stage polymerization. It gets burned before there is time for full-on chicken skin to develop.

Anyone else got any thoughts on additives?

I used dieselkleen before the V3 conversion but have not used anything since. I decided not to use it because I did not want it in the diesel tank for a long time.

So is the verdict...no additives needed for the vegi oil?

I highly recomend a Anti-bacteria treatment,either Bio-kleen,Killem,Bio-con,you pick.Sure beats the hell out of bacteria in your tank,ask any trucker how much that sucks,oh yeah I know all about fuel system bacteria.This is one of the things easier and cheaper to prevent then get rid of.........just my 2 cents:cheers:

greasy,

How often do you put the anti-bacteria treatment in your tank? What are the signs that bacteria may be present? Is adding the treatment after bacteria has begun to grow effective in stopping the growth or is it more of a preventative measure? - Patrick

Patrick,

I use Killem, and i put it in the storage drums after centrifuging. That is when the oil sits around the longest.

It takes only a very small amount to treat alot of oil: like a couple ounces per drum.

By the way, the Material Safety Sheet that comes with that stuff is terrifying. It tells you to basically put on MOP gear before handling it!! Try REAL HARD not to get it on your skin.

Good info. Thanks! Nice lookin rig! - Patrick

Did you have a bacteria problem w/VO??

[greasyX]

All WVO that had food in it and is exposed to oxegen can grow bacteria,especially exposed to ultraviolet light.My run in with the nasty was an IBC on my trailer full of oil.I was unaware of the ultra-violet thing until my oil went Rancid(smells like puke).Luckily I treated it before it went in my truck(bio-kleen and dragged around the yard behind wheeler,at a high rate of speed).Since then oil out side get a reflective tarp over the IBC.The bacteria in the fuel system was bad diesel in a 100 gallon big rig tank,had to dump all of it out and treat tank and fuel,back to step one ADD ANTI-BACTERIAL AGENT............grease out...
