Less CO2 emissions, more energy per volume of fuel, and increased thermal efficiency in the C.I. process (vs. S.I.)... The fuel for my Jeep may very well pay for a new (small) car.

The problem I'm having is that any used diesel vehicle has a large premium over its gasser counterpart. I looked at pre-owned Jeep Libertys and Grand Cherokees in a diesel as well as Jettas and Golfs. I can buy a hell of a lot of gas for the price difference, plus most diesels are double and triple the km's.

(I can't remember if I'm supposed to use an apostrophe in Jettas etc.)
 
lets make this a better fight.

Nobody has said a word about the ethenol. premium gas normaly has 0 ethanol.
ethanol has about 50 percent less energy then gasoline, so even though your reg gas is 10 cent a liter less then premium you may be getting 20% ethanol. so thats 10 percent less energy, 10 percent of 1.35L is 13.5 cents L. so really you can get better mileage on premium vs regular and in the end spend less money.


fight away

(depending on ethanol content of both fuels)

I'll tell you more about my 3.5 HP I managed to ring out right after you tell us more about how Knock retard is based on fuel and spark cut.

You show me where I said that and then I'll defend it. Otherwise, you need to keep your fantasies about me to yourself.

10% is the most ethanol you are going to get so you gain 5% of 10%
Statistically f-all compared to the 10-15c per liter in extra cost
 
What if Israel were to preemptively (got to love those words) strike Iran? Than our whole reasoning for and against US attacking Iran just went out the window. Would the US join Israel or let the 2 sides duke it out. After all why would the US attack Iraq and Afghanistan if not to outflank Iran from the East and West. And if a strike were to happen how much would oil barrels go up given that Iran has the 4th largest oil reserve?

I did some quick research and it seems US (7.8mil/day) has the 3rd largest oil production with Iran(4.2mil/day) being 4th and Canada(3.3 mil/day) being 6th. But reserve wise Canada (175bil barrels) is 3rd at, Iran (151.2bil barrels) 4th and US is 14th at 19.12bil barrels or estimated 10 years left. So it's no wonder US wants to attack oil reserve rich countries at the rate they're burning up oil. Canada has 178 years left of reserve but I think it should be higher because oil sand can be a b to extract and refine.

All cars have knock sensors out of the factory that detect preignition and adjust spark/fuel to eliminate it before any damage can be done.

Couldn't you have just scrolled up and read it for yourself?

Do you know anything about tuning?

Just curious.

Agreed 100%. But part of that offset is the "rarity" of diesel passenger vehicles. You would have to do a lot of driving to offset the initial cost of a diesel.

Good to know.

Dunning’s related interest: “how people bolster their sense of self-worth by carefully tailoring the judgments they make of others,” he writes on the Cornell faculty website.

“That is, people tend to make judgments of others that reflect favorably back on themselves, doing so even when the self is not under explicit scrutiny.”

The higher price of pre-owned TDIs justifies itself. Yes you can buy a lot of gas for the difference between a gas car and a diesel car but when you go to sell that diesel you're going to get more for it. So the price difference is relative (most people don't own a vehicle for the entire life of that vehicle) buy high sell high. As for the higher KMs, Most diesels, with proper service, will easily go 500k. A 2002 TDi golf with 257,000kms is only half way done it's life (or at least that's what I'm banking on for mine lol)

I see that's what you are doing. Obviously, since you felt you had to comment on my post without actually being addressed.

I just don't understand why?

You quoted me, passed bad information to talk yourself up, failed and now you can't let it go.

Still curious as to why you think a knock sensor adjusts spark/fuel when it pulls timing...

That was really all I was after.

feel free to get even further away from the point tho :)
 
Hey! This is great, now you're making comments I can address.

I'm not sure what you mean, are we supposed to ask your permission before replying?

Presumably this is the bad information you are referring to? Clearly, adjusting the spark IS the definition of timing so that leaves fuel. While a knock detection system may not directly control fueling, it will indirectly affect it as a consequence of altering the combustion through spark control. Though I suppose an anti-knock strategy might include richening the mixture as a safeguard, but I don't know if this is ever done in practice.

Let me know if there's anything else that you would like to contest as I stand by everything I said.[/QUOTE]

Make my day and tell me you are a Subaru owner with an Accessport ECU hack and off the shelf map.

That would be gold and would explain everything pretty much. :)

As much as I like to please... no, sorry.

Now is it my turn?

What does any of your line of questioning have to do with the fact that most cars rated to run high octane can run regular octane?
