Aahh… no problem, I keep a legal firm on retainer to handle anything which might raise its ugly head. It’s kinda nice, actually… 
Are these the same lawyers that told you “you owned” a rental car when you you were RENTING it?
I can just see Judge Whopner saying “I’ve heard enough, I’ve made my decision!” already.
Wapner. Please show some respect for the greatest legal luminary since Learned Hand!
Nah, legal beagles are like toilet paper, they’re there to clean up messes. From time to time I’ve gotta give 'em something to do so they don’t get bored & get any more into creating incomprehensible laws & making sure our coffee is lukewarm… or running for office! :smack:
Hmm… Impressive! I’ll take that as a compliment! Thanks!
Thanks, I truly appreciate the constructive information! 
" Hence the gradual addition of diesel, & the return to a pre-problem state if any show up. "
So, if you keep adding diesel fuel till you burn something up, ruin the sensors, or break something, you can magically return to the “pre-problem” state by runing lower concentration/diesel free fuel through the engine?
I did not know that.
Have you performed tests of your car’s stopping distance at these higher pressures, on a variety of surfaces? Considering how much money is put into making cars more fuel efficient, if it was that easy and there were no downsides you have to wonder why every car company doesn’t recommend 45 psi so they can get better EPA ratings.
Isn’t silicone slippery? Is that a good thing to have on tires? Are you spraying it on the tread, or just the sidewall?
Well, you’re taking me out of context & jumping to conclusions, so with the exception of “burning something up”, “ruin the sensors” or “break something”, yep, that’s about the size of it. Just like getting a splash-blended load of methanol fuel from a cheap gas station, or having to purchase high-priced system cleaners/decarbonizers to remove the damage from all the alcohol in the fuel.
I wonder just how “Marvel Mystery Oil” has gotten along so well for so many years? Or any other oil-based additive, of just about all which contain "petroleum distillates = kerosene? 
I’d think, after driving nearly everything from 2 to 18 wheels for almost 35 years, I’d have a good enough idea as to how my vehicles handle both before & after… have you considered that the larger contact patch also hydroplanes easier? That narrower tires perform better on wet roads vs. wider ones do better on dry? That stiffer sidewalls & firmer pressures resist rolling over under hard/sudden cornering? That the auto manufacturers rather their vehicles ride nice & soft like driving on marshmallows because that’s what American drivers have become used to, vehicles that handle like drunken hippos on ice skates?
Go figure! :smack:
PS - Think about the silicone: they used to offer it in a spray can called “Instant Snow Tire” because it released the snow from the treads, that any that got onto the treads themselves almost immediately got worn off by contact w/ dry pavement… SHEESH! What a “maroon”!
So, if something bad and unexpected doesnt happen, then something bad and unexpected won’t have happened?
If you are so DAMN sure it aint gonna hurt a car, why the hell dont you just use your own damn car?
Yup the only reason to use someone else’s car is because of the potential for damage.
Are those Imperial (UK) gallons? That would translate into 60 city/63 highway for US gallons. You general point still holds, but not quite as dramatically.
'Cuz I’m sure that you won’t let me use YOURS!
Cause I got enough technical sense to NOT let you do it. Why don’t you mossey over to the BBQ pit part of the forum and see what people really think about this whole rental car plan?
Hey, check out the info on Wiki, search for “Toyota Prius”. I’m sure that was in Imp. gals, which are roughly 10% more (I think). I also recall that the equiv. was mentioned for U.S. mileage, but their fuels source is most probably different as well.
Wonderful site, Wiki… Thanks!
Thank you for recommending it, bit I’ve got a world of things to accomplish, & like I said before, I didn’t come here for a debate or to ask permission or group approval of the masses. I WORK for a living. Although when I get old, feeble, bored & suffering w/ Alzheimer’s, perhaps I’ll amuse myself there.
Perhaps I was misdirected to this page when I came asking a Question; thanks for letting me know that the “pit” is for hen-pecking & debates.
So the Wikipedia page on the Prius gives a combined US fuel economy of 50mpg for the 2010 Prius, and a combined UK fuel economy of 54.7mpg (both in US units). That’s surprisingly close, considering they likely use different driving cycles.
As for what started this discussion, the EPA estimated mileage for the Prius indeed used to be higher, but in 2007 the testing methodology was changed to reflect what were felt to be more realistic driving conditions (Wired article cited on Wiki). Nothing to do with E10, if that was the implication.
I have enjoyed this thread, but stayed away mainly because of the line quoted above about marine engines being simpler and tougher than today’s auto engines.
What specifically is ‘simpler’?
Since marine engines range from multi-port injected 502 cubic inch Mercruisers built from GM big blocks to sophisticated Honda 4-stroke V6 outboards based on the car maker’s auto line, what exactly makes marine engine simpler? Marine engines are engines with some parts replaced for marine use (such as non-sparking components, brass plugs or other add-ons that can withstand salt/water/etc.
These parts are mostly accessories. The internal and fuel delivery systems on marine engines (filters aside) don’t like water. Keeping water out of a marine engine is just as important as on a car engine. Marine engine internals don’t stand up to water any better than car engines.
So in a couple years, when my kid calls and tells me he accidentally put about 1.5 gallons of diesel in the tank, I’d be better off having him top it up with premium than regular? Or maybe buy some bottles of octane booster and add some of that? (They sell that, don’t they?)
