Hi,

I tend to use an octane rating of 91 or higher for my 2002 Camry LE V6 since
Day 1. Since its very cold here in Canada, is there any benefit of running
regular fuel vs. premium fuel?

Does a Camry V6 require premium fuel? If not, using regular fuel would have
the benefit of being less expensive.

The V6 Engine "recommends" premium fuel, so I follow the recommendation.

In the 2004 manual, it says 91 will give you "increased performance"
and so it's recommended, but I've read that increased performance is
about 1hp or so....

91 WHAT? RON or AKI? This is critical.

It said 91 octane, and some higher "research octane". I don't recall
the exact number. It didn't say anything about AKI.

If the manual specified 91 and then a higher number that it called
"Research Octane Number" (RON), then it means 91 "pump octane".

Pump octane is also known as "Anti-Knock Index" (AKI).

91 AKI is about 96 RON.

I have an '88 camry, 4 cyclinder. What type of fuel would be the best for
me? Do I want something with or without additives? What pump octane #
would be the best? I am a novice and I am learning lots from reading the
newsgroup. Your help and advice is greatly appreciated.

I hope your computer's clock is set correctly. And I hope your ISP's news
server isn't totally screwed, because your posting date is set to this past
Sunday.

As far as your octane requirements go, originally your car called for 87
pump octane, or Regular. In the winter you're fine with that. In the
summer, listen for a light rattling noise from the engine under heavy
acceleration or heavy load. If you hear this, and the noise goes away if
you let off the gas, then you need to upgrade to the next higher octane
level (89?) to see if that makes the noise go away.

Also, all gas has additives. You're either on the West coast or in the
western mid-west (traces to you appear to stop in Cheyenne, Wyoming, after
which point pings are not returned). Those living out there will be best to
tell you wchich brands work best with your engine.

About the only thing premium fuels do that regular fuels do not
do is allow the engine to run at a higher compression ratio. If
you engine is designed to run on regular 87 octane, then use 87
octane. The ONLY benefit of using a higher octane fuel then
necessary is to the oil company, in more profit per gallon,
period.

Well, no. Some older cars (outside of certain select areas that use MTBE)
can develop combustion chamber deposits that can raise the effective
compression ratio, requiring a slightly higher octane rating despite the
manaul's specification, which is why I suggested to the OP that he listen
for pinging.

Thanks for the information. I live in norwest Iowa.
Now...about the computer. My clock is set with the correct time and date.
Any suggestions on what to do about the news server?

Thanks again. This group is very informative and helpful.

I too live in Iowa. Use the 89 octane, it's cheaper than 87 because it has
ethanol added and ethanol is produced here.

yes, the benefit is that it'll save you money. premium (high octane)
fuel is made to resist knocking so that the engine computer can
advance the timing a bit and give you more power (at the expense of
gas milage). but it's not a lot more power, and it's usually not
worth the expense to go to high octane. in the summer, the hotter
running engine sometimes make knocking a little more prevalent, so
sometimes you may need to increase your octane in the summer.

Well Duh! Isn't that what I said was only thing premium fuels do
that regular fuels do not do? ;)

Not really, MikeHunt. TeGGer didn't wander off into oil company

I wonder about the logical skills of those who complain about oil company
profits. Oil companies tend to have profit margins around 7-8%. Microsoft
is over 25%. 8% is not spectacular by any means.

Also, the filling station portion of profits tend to come more from such
things as refreshments, supplies, cigarettes and impulse items. Fuel alone
is a poor profit performer.
