I use two stroke oil in my truck as a fuel additive, and I was wondering if anybody here was using it in their cars? I got a two MPG increase in my truck 18-20 which is a pretty significant percentage increase and I was wondering if the old Benz could stand to benefit from it as well?

IIRC, this was addressed a while back, and the general concensus, was no, it did not help w/MB. I do not know if anyone actually tried it though.

There's a fairly big discussion about this over at the TDI forum. According to the so-called Spicer Diesel Additive Test, SuperTech ashless 2-cycle oil from Walmart beats many diesel fuel additives when it comes to lubricity. It's better than PowerService for example and about the same as the Amsoil diesel additive. I'm currently trying it in both of my cars. Initially I had some injector knock and hesitation probably due to insufficient mixing, but it quickly cleared up and returned to normal. The engine sound is perhaps slightly quieter now, but it's not a big difference and a cetane booster would probably do an even better job in that department. No other noticed change thus far. I haven't had a chance to evaluate mileage yet.

Yeah in my truck i noticed that right off the bat the idle quieted way down, but I have some very aggressive timing curves in it right now so there is still some rattle. As soon as my 300 is road worthy i'll try it in that as well. Keep us posted with your mileage results if you get time.

Thanks

If you think you need more lubricity for some reason, it probably won't do any harm. It won't affect fuel mileage either way.

Additives only make a difference in your mind. Use it if makes you feel good. Otherwise, save your money.

If you like 2-strokes, take a look at this video: http://www.youtube.com/watch?v=vJ8o1gxrW1I

Nonsense.

OK, maybe they don't even make a difference in your mind.

What is the mixing ratio of oil to fuel that you are using?

why not just use biodiesel. b5 will give something like a 60% increase in lubricity.

I am using a pint to 34 gallons in my '07 Dodge-Cummins. I have the 5.9 without all the smog garbage that they had to put on the trucks produced after Jan 1 of this year.
By using the wally oil, it works out to only $1.00 per tank. My truck has common rail inj. I think that it will help with ULSD having little sulpher.
Guys on the Turbodiesel register are using 2 stroke.

If you don't like the idea....Don't use it If you like the idea.... then use it

Wow !

And where did you get this information ?

Distributors put additive packages in the fuel after they get it from the refinery, before you buy it at the pump.

What your saying doesn't even hold with the laws of sience.

Exactly, and by law fuel distributors are only required to additize the fuel to result in a 520 micron scar (I think that's the number), which is not as low as Bosch and other manufacturers would like it to be. Besides additives also have other benefits, namely increased cetane for less combustion noise and stress and water dispersal. It is pretty naive to say that all diesel additives are useless. I'm not saying they are required, but they're certainly not useless. Here's the result of the additive test that I mentioned earlier.


Diesel911, currently I'm using 1 oz to 1 gallon of fuel. I'm not sure if I'll keep using the 2-cycle oil though. I might go back to Red Line's additive which supposedly increases lubricity significantly too and has other benefits. Biodiesel is probably the best when it comes to lubricity, but it won't clean your injectors or help prevent corrosion.

Do you even understand what's being discussed? (Once again, you are trying to *roll a response out of me by exaggerating claims.) We are not talking about distributors, we are talking about the average Joe Schmo at the pump.

We all know the distributors put additives in the fuel before we buy it. That's why additives put in by the purchaser at the pump are a waste.

.

And suppliers put different amounts of additives in their fuels.
I am sure they put no more than they have to.

And lubricity requirements have changed.

The new ULSD has much less sulfur which is a lubricant.
So more additives must be put back into the fuel to keep the same lubricity.

Saying that adding oil to diesel makes no difference, is absurd.

Saying that the fuel that comes out of the pumps now meets the lubricity requirements of all vehicles ever made, all around the world, is absurd.

These cars were made in Germany 2 and 3 decades ago.

And we are just talking about minimum lubricity requirements.

People use synthetic engine oils for the same reasons.
Are the benefits of synthetic oils just in our minds also ?
