Just an fyi lol 5 degrees celsius is still to cold to run a motor oil and diesel mix..
Fml. I had some motor oil (clean) given to me that the person never used. Being that i had roughly 35L in my tank of fresh overly additivated diesel.. I figured <10L of 5w and 10w mixed with atf would be no big deal..
Oh how wrong!!
-
Hmm it would almost appear that i have an air leak... If i leave my small electric pump on to fill the filter i can start and run it at a high idle alright un til it drains the filter.. I can see the IP pull it fast from the filter and then get swept with bubbles. Look like the ol fuel system needs an overhaul..
-
The car will run.. It will just quickly deplete its available fuel supply and then die because of air bubbles.
So i recant, not to cokd for the mixture to run. But too cold for MY fuel system to pull it from the tank..
This fuel filter does have like.. 40k or more and like 4 years on it.. :( dohh
-
where would you be getting a leak pre-filter? At the firewall connection or the tank? Not many places to trouble shoot.
-
The car was originally gas and i never removed all the bs back near the tank.. Lotta places to troubleshoot haha.
-
So basically here is my story, I am 22 and when I got this car at 17 I half-assed everything ;) Whatever, I was 17-19.. Now that I am older and exponentially more experienced, I am trying to clean everything up.. but it can only happen so fast to a daily driver I need on the road.
I have ran motor oil before (hence my confidence to dump this in my tank) in the colder weather, but I think my fuel filter is all sorts of plugged up.
-
It's so hard to relate to how cold it is there. I think the coldest I ever felt was +20F, when I was skiing. I live where the average is about +50-52F, and it's usually nice during the day. Our lowest this winter was +33F. If you're ever in these parts, you're welcome to wrench in my driveway & I'll fire up the 'barbie'.
-
It has been 10F here consistently since two weeks ago when it was -20F.. Yes NEGATIVE 20F lmao.
CALIFORNIA, beauty place :) I do hope to make it down that way sometime in my life. I am going to hold you to that ;) lol

I was just in Hawaii now im in ohio... >:(

dude... next time i want a real pinapple from there.. the "orange" odd ball nothing in usa can replicate one...
oil too thick.. plugged up hole due to viscisity.. drain off bottom gal of fuel by pulling off tank..
-
"....exponentially more experienced....."
Humble as well, eh? :P
Hey, don't any of you Mk. I guys ever put a 200 watt magnetic heater on those steel fuel tanks? I used to do that a lot in cold winter when I had that vintage of junker. THAT is one thing I really miss about those earlier cars. It don't work too well wiss these plastic tanks........
-
Haha nope, but I will be putting a torch to it tomorrow! LMAO
-
Thrift store electric blanket would do the trick too.
-
I'd siphon as much as possible out the filler neck, dump a buttload of PS911 in the remainder and warm the bottom of the tank with a 400W heatlamp.
(And change the filter, duh. 4yrs?)
-
Thriftshop?? (http://www.youtube.com/watch?v=QK8mJJJvaes)
-
I was thinking change the filter and get it running and then go add some gasoline to the mix. hah
Yes 4 yrs. It has not shown an issue at all until now ;). I had a replacement, but I used it on the woman's 88 when we revived it back in October.
-
sadly I have heard that song or lack of song before. My kids think it is funny as we have several thrift stores in our area.
-
You take that back right now. That song is totally awesome. I wear your grandpas clothes, i look incredabowl!
-
Incredabowl maybe F--ing awesome? NOT!
-
You two are just too damn old to appreciate the music in the world today ;).
Now before you judge me, know that I love Bieber, Cyrus and One Direction.
And now take me seriously, 70's Rock till the day I die :D From time to time a catchy tune pops up and I DIG THE HELL OUT OF IT LOL.
-
Let me guess. Call ME maybe? Your fav?
To OLD?
I have original Zepplin vinyl that is nearly worn through. Wind that player again Maw.
Still enjoying, and signing music, So there you whippersnapper!!!
-
Talk about off topic!
-
Yes, you are on old fart. If your kids are older than me, you is olddd looool :)
I have read a good idea. Adding a 12v relay'd pad heater to my fuel filter for just such cases of gelling and to help warm the fuel for the first bit of a cold start.
I've got the 120A alternator, so my electrical system can handle it. That and one of these (http://www.frostheater.com/) circulating heaters will definitely be on my upgrade list ;)

I'm not sure I'd want to load the battery with a 12v heater (other than the glow plugs).
Typically, the filter should flow fuel easily enough in very cold weather, plus an inline pump there should be no issues unless the fuel is unreasonably thick from adding heavier oils. A larger bore filter setup (or two filters in parallel) would be a way to minimise fuel restriction without loading the battery more.
An engine heater is nice... the cabin gets warm fast and the start is easy.
-
Are you against loading the battery more for any particular reason? If this were a GLS TDI it would have had the glow plugs, glow plugs in the coolant line, heated seats, rear defroster on and charging the battery back up on a cold start with the same 120A alternator.
I am not too worried about frying the alt, and I have a 9 year warranty on my battery.
An engine heater seems like a way better route than a block heater. For it to be perfect, it should be able to provide like 7v to the cabin fan to run it on low while it is circulating coolant... it would keep the cabin warm and possibly even all the windows ice build-up free.
-
Only concern is the battery load before/during starting... after starting and the alternator is up, no worries.
-
Gotcha. Yes I kinda figured you probably only meant pre-start. Well Yeah, the 12v heater would only be for no start gelling issues.
-
My owners manual says that is ok to add up to 25% gasoline to diesel
if the fuel is gelling. That said maybe you could pump a couple of gallons
of gas into your tank. I don't know how you are going to mix it though.
-
Gotta be careful there, that manual was for Diesel 20+ years ago.. The new LSD and even newer ULSD cannot have a 25% gasoline or kerosene mixture as they could have before.
Old diesel had lots of lube, new diesel.. not so much. It will run, but for how long till your pump goes boom..?\
The tank is nearly full to the brim lol.. which is why I saw it fit to add the oil. I had a full tank of diesel with more than enough diesel additive.
-
Hi
I thought since you were running almost straight motor oil,
lubrication would not be an issue.
-
For me in my particular situation. Yes. But you referenced the manual, it would not account for any motor oil in the tank lol.
So just to be clear, thought I'd state that that piece of the manual does not apply anymore to winter blending.
Also far from straight motor oil, only about 22%.
-
So it was definitely a plugged fuel filter.. Didnt show any signs just one day plugged. Even after sitting in a +10 garage all weekend. Sunday morning fired and ran for maybe 3 mins before cocking out.
New filter on pulled fuel from the tank a d it is idling as we speak.
-
If you haven't done it I might recommend that you open the filter element to see what the nature of the contaminant was. Running 22% motor oil might have something in it. It is always fun to see what is coming into filters.

Un related but involves a mix of diesel and motor oil....
I had cut down the fork springs to stiffen them on my dirt bike. The only oil I had at hand to refill the forks was some 15w-40 motor oil. I was sure that it was too thick to run in the forks. I looked around and thought, add some diesel. I poured out the motor oil into a container of what I thought was about enough for the forks. Added about 25% more of 20% biodiesel. I mixed them up and decanted them into the forks in the proper amount.
The oil was pretty close to the consistency of the oil I had removed. Sure enough the forks work fine, smooth, controllable. No leakage in the past two years. I wouldn't have done it in the sump but for the application it worked good.
-
For clarification, the motor oil was clean. Just 15+ years old lol.
-
So no connection between the clog and the oil?
-
I will be opening the filter, but no I do not think so. I think it was a partial ice clog.. that was still allowing the thinner diesel through. The thicker oil diesel mix got plugged up. Old filter weighed like 5lbs and when i opened the drain nothing came out.
However when I added some heat I got a lot of crap to come out of the filter, so it must have been froze up.
-
it is possible that motor oil does cause a coking of the rings, as you mentioned Jeremy.
I only say this because I have a pretty constant cloud that follows me as I drive. Has a nice blue tint, most noticeable during acceleration, clearly unwavering.
But then, my primary GP wire fell off, so my GP's stopped working. Drat. I thought i heard that relay clickin, so i figured i must just be down a plug. These duraterms had been soo good, how could one be bad now. So i had to resort to the no-no juice on the coldest of days we recently had (a bone chilling 10F a few nights in a row!) for 2 mornings. When the ether lit, it would actually push the piston (and the starter!) backwards.
Well i tell you i think the no-no juice had a kind of positive impact on the damn thing. After it was no longer so damn cold, i set out to find the break in my GP relay wire, i hooked it back up, and it starts much better! no more smoke! Well, for a week anyway. It promptly went back to being a pig, and smokin light a freight train, but there was a week of clarity for the little thing, directly after huffin ether.
-
Yeah, but you are running the least maintained engine on 100% WMO..
lmao! I am kidding, I have no idea on your engines maintenance or anything so its hard to say why you smoke. It is unlikely from the oil, as diesels don't really do the whole blue smoke while idling thing. The oil will burn in the cylinder upon combustion and just come out as more black.
I think you are severely retarded on the timing if it is hinting blue whilst smoking.
-
I decided it was like when a diesel smokes white after first start up (incomplete combustion) but it's motor oil so incomplete would be blue.. What you think?
-
It should still be "white-grey". Gas engine smoke blue when they ingest their own oil because the throttle plate has not allowed anymore air to burn this new fuel, not that it would be heated enough with only 125psi and a spark ignition engine anyway.. So this then causes an extreme rich mixture. I can go richen up the Holley on my Cougar and make it blow tons of blue at idle, but it is not burning any motor oil.
I have found that when a diesel smokes blueish grey it is 7.7/10 retarded timing related, the other 2.3 times it may be bad injector spray causing severe issues with atomizing the fuel. When I had my 88 timed way to advanced in the cold it would blow pure white clouds at idle (after you eventually got it started).
What happens when you put your foot down at 2000RPM and your turbo hasn't spooled yet? You are physically allowing the pump to inject its maximum throttle quantity of fuel and no have provided more air to support 2000RM. The result is black smoke, fully un-burnt raw diesel particulate. Being that there is no throttle plate the cylinder will always be extremely close to a stoich A/F mixture. Without a turbo there is the same amount of air in the cylinder for each intake stroke at idle as there is at 4500, yet you can inject all that extra fuel to sustain 4500RPM.
What I am getting at is, the ounce or two of oil that may be burned in the cylinder should go unnoticed, the fact that the smoke trail follows you after you rev up and start driving kind of confirms injection timing. If it were still only ingesting an ounce or two of oil it should just be added to the diesel and burnt.
SOrry OP for the threadjack, to the original poster
I am going outside right now to see if she will start today and cut open my old fuel filter if I can find a hacksaw!! LoL
