gasoline
 

Just wondering ... I recall in the older cars they used to say to use
87 octane but once in a while use 91 octance on occasion. Is this
still valid or is going with a lifetime of 87 octane no different say
in 2003 or newer Hondas (say Toyotas too) ?

I think that was because in the older days, when the older cars were
around, the fuel vendors put more cleaners into the higher octane fuels
as a way to market the higher octane (higher priced) fuels.

So "use 91 octane every now and then" was actually "use a fuel cleaner
every now and then".

About 15-20 years ago, the feds came out with minimum standards for
cleaners in fuels--so that even the lowest octane fuels now have a
decent set of cleaning additives.

No need to use a higher octane fuel anymore.

HOWEVER: that's not to say that all fuels are the same. Please notice
this web site:

It's intended to be a standard that exceeds the federal standards.

I can tell you from personal measurements that Shell gasoline is cheaper
to run than anything else I have available around here. Sure it's a
couple of pennies more expensive per gallon, but the benefits are clear
to my by actual measurement of cost of gas per mile over a long period
of time.

so you still haven't bothered to read your $25,000 owner's manual...
why am i not surprised? [rhetorical]

Are you still missing some bolts and nuts ? Your name and type person
together says you are.

quietly enough to stop asking dumb-ass questions hopefully.

It was never valid. Use octane to allow a greater compression ratio
and reduce pinging. It's not good for anything else.

Perhaps the idea was to use a higher quality gas, with improved
detergents, every now and then.

Appreciate the help. I know for my new CR-V, 87 is all that is
required. I read and asked when I purchased it but I still wondered
if the old rule in this new Honda could still apply. For a while I
did this for my 2003 when it was new and in the last year or so did
not and I can't tell any difference.... no knocks, pings or whatever.

You're going back to the '70s on that, I'm sure.

A lifetme of whatever the manual specifies is just fine. Modern gasolines
and fuel systems are far advanced fom the '70s.

There's no harm in most vehicles in using an octane higher than
recommended, so if it makes you feel better to use 91 on occasion, go
ahead.

I suppose there could be a few cars on the road where the use of any octane
higher than specified is forbidden, but that would be made VERY plain in
the Owner's Manual.

You're such an . Why would his owner's manual include 70's
folklore?

Thanks. I know for a fact 87 is the required octane. I had already
read that from honda.com on the CR-V prior to purchase. Some cars
like Infiniti require (suggest??) 91 and that can be a pain to
remember if you have other cars at the same time using 87. I guess
I'll just stick with 87.

Any opinion on gas additives? Honda.com says nothing about this so I
imagine the same answer here. I guess I have a hard time accepting
87 for life <grin>. Thanks Tegger.

well, the rule is still kinda there, in a way, but you have to
understand the underlying reasoning behind the old "use 91 octane every
now and then" story. It was about detergents, plain and simple.

Octane level in and of itself has zero bearing on how well the engine
runs or what kind of power you can get. The manufacturer specifies an
octane level of fuel; going above that isn't "better" gas and doesn't
"give you more power". Especially nowadays, when the computers tune the
engine dymanically as you drive. The computers have fuel/air maps set
into them from the engineers, and programmed responses to knock and
oxygen sensors and whatnot, and providing a fuel with higher octane
doesn't change the computer programming.

Honda specifically warns against the use of additives of any kind.

I used to add the Techron stuff once in a while, then I stopped doing
that years ago. I can not tell any difference except that I now spend
less on gas additives.

Speaking of, if anyone here has experience with the Wintec Tec3 engine
management system, I have a couple of questions on something before I
make some adjustments to the current settings.
