The point is this. Under the Magnusen-Moss warranty act it is essentially illegal to state that a car owner must do something for which there is an equivalent option that can save that person money.

For instance you can change your own oil with an appropriate grade you buy anywhere you choose instead of paying the dealership to do it with car-brand fluid....

It would appear that the Big 3 are in cohoots with Big Oil. Now that gas prices are at over 5 dollars for Diesel, I am sure of it. Also they claim that they can't make an all gas fuel efficient engine that gets 50 mpg and meets modern emission standards, yet in 1993 Chevy/Geo put out a three cylinder Metro, that is a very decent quality powertrain and boasted in the 40's city and over 50 highway. So it's all BS and a way for them to get you to buy hybrid technology which costs way too much and makes them a ton of profit.

I can say this: Biodiesel cannot void a warranty, because it is equivalent. Dr. Diesel made his diesel engine to run on peanut oil. Almost any oil including engine oil and transmission fluid will work fine. The problem is the level of contaminants, and viscosity.

I am very unhappy with the Big 3 for deceiving the public about these issues. I believe that all of these vehicles are compatible with a whole host of fuels that are not even in use-- and not just Biodiesel per se.

The seals that are in Diesel engines are completely compatible with Biodiesel, this is just another example of a deception perpetrated by Ford and GM to keep people from making their own fuel. The problem is not Biodiesel but diesel in general that causes problems with certain types of rubber, Gunther, you have it 1/2 right there.

All of the evidence actually shows that the lubricity of Biodiesel is excellent, and actually better for the injectors, and it has the added benefit of lower emissions. And it cleans your entire fuel system much better than petrodiesel. So I really want the Big 3 to publish engineering data to contradict known facts.

I have seen people stress that only Viton is compatible, but Buna-N is for the most part acceptable as well. Again there is a lot of variability in the quality of rubber over the years, but now things are much more consistent from manufacturer to manufacturer.

So it's really important for all of us to band together not to accept this phony baloney and dishonesty. We must demand what is right and good for the future of motoring.

Yes but this unit is a real peace of audio gear and your Tascam has a 12 cent digital clock and is a piece of junk!
