From my experience is that higher octane really give it te good gas mileage boost if you love it. * but i did that test by mixing 91 with 100.... cuz california sucks.

Ethanol blend in australia is often contaminated with paint thinners.
We recently had our sydney western freeway blocked by broken down cars that were using E10.
So when driving here we should use premium 98

True it gets less gas mileage... and so what? Doesn't mean it's bad for the engine. E10 (sorry my bad, not E15) does have higher octane.


The fact is, by design this car's oil does run above boiling temp. It's for getting rid of water in the oil as much as anything. It's by design. On a tracked car, if you modify for FI or whatever, you may need an oil cooler. But for a regular DD it's worse for the engine to have one and run the oil too cold. If you do track it and you're NA, install a bypass on the oil cooler and only use it when needed. There's a reason Toyobaru designed this car to run as hot as it does and it's not a mistake.

As for the wet t-shirt contest... 1) no pics, didn't happen 2) don't confuse water boiling off with evaporation. 2 totally different things.

Well, the only picture I have is of the winner.

As far as stuff boiling and evaporating ........ I ain't tupid ....... I learned everything I needed to know about that stuff from my uncle, back in West Virginia ...... so there!

So just how much water do you think gets in there? Where exactly does this massive quantity that needs to be "boiled off" come from? Where does it "boil off" to?

reliability mods? best mod you can do to your car is simply not modding or changing a damn thing and driving the car for reliability and complete issue free ownership. now some good protective mods to increase reliability would be getiing mudguards installed to keep lower panel damage to minimum, clear bra or paint protection film and fabric guard application on the interior uphostery and getting the all weather floor mats ;)

fify, unless, of course, you can point us to some design documentation. I'll gladly accept that.

Now, about all this water that needs to be boiled out of the crankcase .......:popcorn:

*sigh* :popcorn:

That's a ridiculous claim, sorry.

My friends brand new civic was destroyed filling up at a BP servo and he uses nothing but 98 (part of that train of destroyed cars on the freeway). Those cars lined up with hydrolocked engines were due to water seepage into the servo fuel tank. I have a picture of a water bottle showing the contents of the supposed fuel showing all the grit and water.

Assumptions are dangerous and contribute alot of misinformation

I've run nothing but e70+ for the past 3 years

What do you think gasoline is?

My mechanic has warned me not to use any ethanol blended fuel in any of my cars.
He said that the poor quality of E10 in sydney is destroying engines.

My father was obsessed that gas stations used Varsol to cut the fuel and make more money and that by them doing tis they ruined his cars (the reality was that 100K+ with no oil change tends to cause issues).
I tried in vain to point out the economic reality of this but he never understood.

Retail price $2 a gallon

Even at wholesale cost it makes no sense whatsoever for anybody to use a material that retails for $12 to stretch a product that sells for $2.
That is not even considering that many paint thinners are barely even combustible much less flammable enough to use as a fuel additives.

Isn't it a somewhat closed higher pressure system? That raises the boiling point... ;)

I'm surprised no one has mentioned the garage mod. Keep it out of the elements.

Or the other car mod... Don't use it very much! Recommend pairing with the garage mod.
