Chain saw 2 stroke oil is blue, at least the stuff I use. that was my first thought when I saw the bottle of blue fuel.

Kerosene is clear as I remember, and Diesel is not too far removed from it. so Iam thinking the refinery probably adds a dye to the fuel for identifying purposes. Like red Diesel has a dye, it might have been clear from the start.
What color is jet fuel? It is a close relative to kerosene.

The topic here is the color of the fuel, no where through this thread did I read the the OP has a engine running problem of any kind.

Now if the engine is running w/o any difficulties, what is the real problem?

Kerosene has dye in it around here too. I have not bought any in a while. I forget the color.

No problem I guess - the fuel looked dirty or contaminated with algee or fungus - so I thought... at the end here I have to believe that it was a 2 stroke oil that the PO had added, at least that's the conclusion I've come to with the help here.

Side note - I've pulled the tank screen - but that's whole another story... stay tuned....

James,
How is the exhaust? Did you notice any change in the oil level on your long trip?

If your exhaust is clear and the oil level remained the same I don't think you have to worry about your car dumping oil into your fuel.



Kerosene is clear here. Diesel looks greenish to me. I bought alot of pump B80 this summer and it looked the same as D2 (which is B5 around here statewide).

Well, funny you should ask - as I said the car is new to me and one strange thing about it is the oil readings. I've been checking it frequently on my trip home from OK, but the oil levels were sometimes confusing. At some point I observed that oil level had dropped about 1/4 inch lower than my original mark that I've observed at the start of the trip - then next day, it was back to the same mark as before. Now it's down about 1/4 inch again - this has been kind of bugging me as I have not been able to conclude positively wheather or not the oil level has really dropped. I figured I need to change the oil to Rotella T 15W40, observe the initial mark and take regular readings at regular intervals (i.e. in the mornings after the car had sat all night on level surface) - hopefully there is no oil consumption - would not make me happy as my 300D at 200K+ does not take a drop.

In terms of the exhaust the car does puff some black smoke - that's all I ever observed never seen any other color. I figured the occasional black smoke during accelearation should be normal particularly since the ALDA has been removed.

THe oil level stability is something I have to determine but it will take a bit some time. So for now, I'll keep my fingers crossed and hope for the best.

Thx all -

You bought the car in OK, drove to Denver. so you must have filled up a time or two.

So if the PO added 2 stroke oil to the fuel, it should be run out by now or diluted down pretty well.

Dang it - there you go messing up my theory... hehe You have a point there...

IF the IP is leaking oil to the fuel and it should need resealing - what do we talking here - something that's do it yourself or does it mean taking it all apart, replacing internal seals and re-timing the IP afterwards, etc.

James,
I can't help you on the IP r&r, but the oil fluctuation probably has to do with checking the oil level when the engine is warm vs cold. It should be higher when the engine is warm. As long as you are not noticing a continual drop I wouldn't worry about the IP at this point. I would go down the path of a dirty tank first.

Oil in fuel is more often caused by the O-ring going out on the lift pump. Will seap oil back into the fuel line and supposedly a bit of air as well. For some reason of the design the fuel does not seem to end up in the oil only the other way around. There is a rebuild kit for the lift pump or you can just replace the entire thing. Just another thought before you worry about your IP.

I wonder if the fuel would turn color if you run the car on a bottle of fresh diesel in the engine compartment, like you were doing a diesel purge?

That might rule in/out oil leaking in to the fuel.

I agree with Charlie that, if you drove from Oklahoma to Denver, any 2 stroke oil in the tank would have been diluted and burned. Drats, I thought we were on to something.

Are any of the fuel additives blue in color?

Startron? Or is that just a blue bottle?

I haven't paid attention to the color of my diesel, but when I had biodiesel (B100) it was bright yellow.

I this this is a brilliant idea... I'll need to do that - as soon as I change the filters.

Thought I would post the pic of the tank screen when I pulled it out last night - it's relevant to this discussion! The squeamish may need to look away..

It sure was oily sticky and gooey - I had to scrape the walls off with a little screw driver and then brush it with tooth brush and plenty of Brake Cleaner - came out clean and thankfully undamaged. Only the rubber seal needs to be replaced.

If the strainer is that bad, I'd pull the tank and clean it. Removing the tank is pretty straightforward - only 4 nuts after you've pulled everything else out of the way (first aid kit, vacuum pod - minor stuff).

Disposing of the residue may be a problem. I'd probably use biodiesel as a cleaning agent - slosh a few gallons around in the tank, to rinse off the loose stuff then let it sit and soak (put the screen back in). Drain it into a waste bucket with lid (Lowe's) and take it to your community hazmat drop off.
