I noticed today that the neighbourhood CHEVRON gas pump has
"with Techroline" written on pumps that vend unleaded and
super unleaded variety of gas.

My question is what is techroline and what does it do?
(i.e. is it an octane booster or a detergent etc.)
Also, what effect does it have on all the fuel hoses ?

My owner's manual (1984 Honda Civic) explicitly prohibits
use of gas containing Methanol or more than 10% ethanol.
Someone told me that Methanol or too much of ethanol was
bad for all the plastic in fuel lines and other parts
in the fuel system. Since I do not know what the composition
of techroline is, I am wondering what effects, if any, does it have
on the longevity of my car.

Changing gears a bit, I am planning to change the coolant in my
car. It has Aluminum engine. The owner's manual threatens of
corrosion setting in if
1) coolant/water ratio is below 40/60 (they reccommend to keep it 50/50)
or,
2) the coolant used is not of proper type.

I can take care of the 50/50 ratio part of it. What brand is
good from anti-corrosion point of view. Is Prestone okay?


Please send e-mail. I will summarize for net if there is enough
interest. Thanks in advance.....
