EV Mod
Should we have a disclaimer on mods such as the EV mod? (May void warranty, etc) Also, the entire section should be fleshed out more with information on when it is possible to use EV mode and when it is appropriate to. I don't have one, but if nobody else expands that I will try. - FourOhFour 18:18, 4 November 2005 (UTC)

Sure! NuShrike 22:04, 6 April 2006 (UTC)

Wow. I sort of forgot about this comment... I'll look into the EV button and try to add some more info on it when I get a chance. FourOhFour 00:23, 17 April 2006 (UTC)

Purchasing Tools
71.224.246.98, can you please explain why you've been commenting out entire sections of the lower part of the page that does not include Purchasing Tools, for the second time? NuShrike 23:03, 6 April 2006 (UTC)

Well Kiloran, you've sorta explained your edits on the page instead of coming here. But still, if editing to offline the calculators, please be exact with your commenting and not include everything else. NuShrike 22:27, 11 April 2006 (UTC)

-- Actually, I only became aware of discussion section through your history comment. This page is my only experience with wiki so I'm not particularly expert. I thought I had limited my commenting to the Purchasing Tools section, of which the calculators were the sole contents. My appologies if my edits inadvertantly affected other sections. -K

PHEV
I would create a book about Toyota Prius PHEV conversion. How to convert a Prius into a PHEV Prius. --193.145.201.52 10:27, 4 October 2007 (UTC)

Fuel
When I saw the text under "Fuel", I just couldn't ignore some serious factual errors:

1) Avgas is not kerosene; it is gasoline, and there are several varieties (80, 100, 100LL, etc.). If avgas WERE kerosene, my airplane would not fly and I would be very unhappy. Jet fuel (JET-A, JP4, etc.) is essentially kerosene, although it's not a good idea to fill your jet aircraft with commercial kerosene, for a variety of reasons.

2) The sentence on high-performance engines was out of place and factually inaccurate. In internal-combustion engines, power is produced by the thermal expansion of gases heated by the combustion of fuel. Generally speaking, burning more fuel (or burning it hotter) produces more power. Large-displacement engines burn more fuel and high-compression engines burn it hotter (and require fuel with a high antiknock index to ensure the ignition spark results in deflagration rather than detonation). At any rate, the discourse really doesn't belong in an article on the Prius.

3) The term "octane" historically refers to how well a fuel resists autoignition while being compressed, as compared to a mixture of iso-octane and heptane. Fuel that resists autoignition as well as a mixture of 90% iso-octane and 10% heptane is rated "90 octane". Unfortunately, there are in use several different systems for determining octane equivalencies, meaning the same fuel can have many numerically different ratings.

4) Aviation fuel is rated using the Motor Octane Number (MON) system, as is automobile gasoline in many countries. MON is a component--along with the Research Octane Number (RON) of the AntiKnock Index (AKI) commonly seen on gas pumps in the United States. Therefore, the statement that avgas is rated using a different system is incorrect.
