I've been adding 2 cycle oil to my VP-44 and my wife's 12V since 2001, 8 years now. Pulled the injectors once and they looked exactly as expected. No evil 2 cycle "gum" buildup.Now to the interesting part: I bought another used 3500 2001 with 117,000 miles. Shortly there afterwards, I started getting low power periods and P1693 (?), the code for "internal timing error". I didn't have the time or money to replace the VP at that time. So I experimented with heavy dosing of 2 cycle oil in the fuel. <100:1 mix ratio. I was able to drive the truck several more months before replacing the VP.My son didnt believe me about 2 cycle oil, his VP died at about 150,000 miles. Same code. He decided to try the heavy dosing of 2 cycle oil, and he was able to drive the truck for a month. But if he forgot to add the 100:1 2 cycle oil back wouold come the P1693 code. I had the same experience if I forgot to heavy dose.Is the heavy dosing a "fix"? Answer: no, the damage is already done, but the extra high dose of lubrication got the timing ring to move again.Suppositionally, I suggest that increasing the lurication quality of diesel fuel will prolong the life of the injection pump and injectors, since both are mechanical and I have not see a mechanical device that didnt benefit from improved lubrication.

if i have heard one person say "ULSD stinks" or "it smells different"......than i've heard 10 people say it...since i have NO experience with it...i thought i'd ask.

I think number 2 home heating fuel still has sulphur in it, and it smells stronger? Not too many natural things on the earth as smelly as sulphur. Come to think about it, ever been in a place with sulphur water? I was at a car wash the other day, and when I pulled the trigger, what a smell, atomized sulphur water!

Not really sure how ULSD compares with LSD, think it might be a little stronger. I know that one drop of biodiesel seems to make the entire tank smell like french fries. Either way I would rather smell diesel than a gasser exhaust that makes me gag.

That's funny... I remember day of driving gasser and always though the smell of diesel was nasty... Now gasser really stinks and burns your eyes compared to diesel.

Just about everyone I know is biased on which smells awful. Everyone who owns a gasser gags on diesel fumes and vice versa. I really can't stand it though, all you see on gassers is white smoke and water pouring out the exhaust like some chemical plant. ULSD burns my eyes a little, we run B5 LSD in our tractor and that is truly some good smelling stuff, doesn't burn my eyes either.

I don't care for the smell of either my self, but the diesel is usually consistent and cleaner burning, because it burns all the fuel, and if it is old and burning oil due to wear, it will burn that away as well.

Same here Mike, but now... there is nothing like the smell of diesel in the morning!! lol .... ;)

Hey guys just thought I'd let you know that KTM (the dirt bike company) makes a 100:1 premix oil for there bikes i haven't used it, but by the sounds of the label it should increase lubricity at low oil/fuel 's mixtures thus allowing a better burn. Probably be good for a diesel premix, i don't know what's in it though:shrug:

Might be good stuff, but it's hard enough to find the dirt bike, let alone oil for it. Yes I ride a KTM I think the oil would be pretty pricey too. They do like to run pretty lean on the oil though, they load up if you run a ratio that all the other dirt bikes run on. It might be really good stuff but it would be so hard to get. You would have to order it and have them UPS it to you or something, most of us anyways. That's the basic reason why the walmart supertech is so sought after, it is everywhere.

My take on the smell is that the old diesel smelled, the LSD smelled less and there is little smell to ULSD. Also I have seen NO cloud in the tank on ULSD like the old diesel when the temps dropped below 20F on summer fuel - might be running 400:1 2cycle on a Detroit.

I looked into that KTM oil it's $20 a quart and there's a local store who sells it about 10min away from my house, although that doesn't mean it's readily available. as soon as I'm no longer broke I'm going to give it a shot and she how she does!

Isn't that just a bit expensive? I normally buy 2 cycle oil for $11 bucks a gallon.

Sulphur, OK is the smelliest place. you can smell it in the air(and stuck to the back of my mouth). the first time i went thru there, it made me sick. why would people settle around that?

walmart has 2 stroke for $11 a gallon. haven't used it in a while, since i've been buying B5 fuel

Question Does any body know if I could use 2 cycle oil on my 03 jetta tdi ?

You might try jumping on some of the tdi forums out there and asking those guys. Im pretty sure the vw's of that era run bosch pumps as well with the computer on the pump so theres some similarities to our trucks with the fuel systems.

Yes. But you'll have to figure out the mixture ratio that vehicle likes best. Start at 200:1 and work your way towards 128:1 and watch you MPG and exhaust smoke.
