Title: Burning 10% hydraulic fluid
Post by: Dakotakid on May 03, 2009, 09:23:39 pm
I wasn't quite sure where to put this.
I finally "came into" the 100 gallons of hydraulic fluid I have wanted to acquire. This is expensive Cateprillar 10 wt. which was only in a large machine 8 hours before removal (they burned up the engine right after service job). Filtered to 2 microns. Mixed at 10% with premium #2.

The engine is '86 N/A hydraulic with new bore (2nd over) Prothe (Right Way Industrial) pistons (sorry guys....I've had really good luck with these in two engines) with about 8,000 miles on them. Nicely broken in and virtually no oil consumption even with hard running.....very pleased with this engine since rebuild.

I came into this expecting nothing....was trying to rule out "placebo" effect in my head. Actually, I expected all sorts of bad stuff.....smoke, stink, bad idle, bad cold start behavior, hesitation on acceleration, the potential for coked cylinder walls.....figured I would be dislocating my knee while attempting to kick myself for trying this. Understand????

OK, fine. I've only done about 100 miles. What's it like so far??????
No cold start problems (warm time of the year though), a little more smoke under hard acceleration or up long hills (nothing too noticeable though), markedly quieter idle (warmed up....like a turbo motor is "quiet"), smoother idle, and best of all........like an immediate 5 or 6% power increase. Wow....I wasn't expecting this to be a positive experience!!!!!

So, looks like I'm going to be doing this for the next.........well, 1000 gallons or so.....unless poo hits the fan. I'm not totally sure I have the nads to go to 15%. But, I've always heard that is safe. Think I will hold the line at 10% for now. It feels neat.....like always having a tail wind!!!!!

Neat!!   Keep us posted how it works..  Personally I think I woudl stick with 10% for the next few months since temperatures still aren;t all that stable...

Just got out to the farm...75 more miles. I should NOT have said 5 or 6 % increase as I have no way to quantify this. So, let me just say that all rpm acceleration is noticeably enhanced. Really noticeable in town...as the engine really grunts off the bottom and into the mid-range as felt by seat of pants.
I was also able to maintain momentum on the rolling hills between residences.
I don't think burning more would be better. Plus, I am afraid of coating the cylinder walls. The gain must be so noticeable due to such a fresh engine......hmmmm. Anyway, suffice it to say that I don't bs about this. Wonder what it would do in a good turbo?? My Eco is not currently licensed so checking into that is sort of out right now.

i'm wondering if the added lubricity in the fuel is adding to the power?  maybe there is also more BTU's in their hydraulic oil?  this is really good news because heavy equipment operators are always changing out their hydraulic oil... all you'd need is a centrifuge to remove water/dirt/debris.  i wouldn't mind seeing the specs of their hydraulic oil, such as cold pour point, viscosity (are they all 5 weight?) etc.

hmmm now to find me a supplier  :lol:

My brother is a mechanic at a dealership, so he has access to all the used ATF he wants, free. He filters it to 1 micron and mixes 50% for both of his Dodge 3500 crew cabs. He said it starts to smell too much when he mixes more than 50%. No start issues.

If you heat the oil (hyrdo) up to engine operating temp you could burn it 100%. it is no different then burning WVO in my 1.6 caddy..  hydro is probaly cleaner( less water) then wvo

Did another 170 mile trip today.....slightly more smoke than with straight fuel. Not really any more ash/soot on the back of the car than usual. Starts right up on 45 F. degree morning.
It idles so much quieter.....sure gets down the road. No complaints right now. I've got to finish assembling my last rebuild real soon, and I might put it in this car. If I do....I do not want to run this oil in an engine that has not seated the rings yet. So I would have to quit for awhile.
I wish each day was about 72 hours long!!!!!!!

No issue with burning hydraulic fluid , Atf has a similar dye in it to marked diesel. If your tank is dipped by the cops you may get fined for road tax nonpayment. Actually happened to one of the guys on the biodiesel forums. Just a word of caution. Cheers Dan

That is sooooo dumb that you can get fined for running your car on something other than what they sell at the pumps...
It's robbery is what it is.

Its so you don't run farm, mine, marine etc. fuel on the road. If you don't drive on a public road, you don't pay the same tax on fuel.

Thats the same as over here in Ireland.
We have green diesel and red diesel both of which cant be run in a road car as the tax wouldnt have been paid on it.
They dip on a bridge in my town at least once a month and is the reason i havent tried running paraffin even in small concentrations as they will pick it up and fine/lift the car.

this is why you need to create a dummy tank  :wink: always outsmarts dems laws people  :lol: what are they gonna do? ask you to drop your tank, or do an ultrasound/radar/sonar and be like "wtf there is a wall in your tank!"

PLUS... when my '86 jetta was scrapped it had a full tank of fuel in there.  so i thought hmmmm i must siphon this fuel out into my next diesel jetta.  there is a bloody screen there which makes that virtually impossible!  so unless they have a surgical needle, they aren't able to dip these cars (do they all come with that screen?)

You were scrapping it, get underneath with a sharp punch.. LOL

I dig the idea of a false tank :) lol
