That's right, I imagine my valves hitting the pistons or whatever that
makes a repeated ticking sound when I step on the pedal.
What exactly is that sound coming from?

Read those links in my last message. It's explained nicely.

Toyota can't be any more specific because they have no control over the
quality of the gas you buy. About the only thing they could add to their
guidelines would be to close the windows and shut off the radio regularly,
so you can hear any new sounds the car might be making, including engine
knock.

Based on my experience, it's most noticeable when accelerating. Sounds like
ticking.

Sounds like several glass marbles being moderately shaken in a small
coffee can. A rapid fire rattle that gets louder the harder you stomp
on the Loud Pedal.

On well soundproofed cars you will have to roll down the windows to
hear it, but then it should be audible.

Any injector or valve ticking will vary with RPM, but not with
throttle application.

The parts department should be able to order you an owner's manual. And, if
the customer service sucks that bad at the dealership, I wouldn't give them
another dime's worth of business after getting the manual.

I don't get why for an owners manual -- anyone would go to the dealer
without seeing if it's on eBay first. If it's on eBay, it's almost
hands down cheaper than the dealer.

But, do as you wish...

I have several friends who have given me the exact same advice. They
have recommended either of two other dealers who are within 30 miles.

PS I asked the first if they had any brochures on the Tundra or Tacoma
and they did not!!

You can download the Quick Reference Guide (not the complete Owner's
Guide) for many Toyota's from:

http://prg.toyotapartsandservice.com/

The Quick Reference Guide for a 2007 Tundra
(http://prg.toyotapartsandservice.com/pdfs/2007_Tundra.pdf ) does not
mention octane at all. However, the online iGuide (see
http://www.toyotaiguide.com/iGuide_Tundra.htm ) allows you to view a
complete copy of the Owner's Guide for a 2007 Tundra. This guide
specifies the octane requirement as 87 for all engines.

For the Tacoma, there is no online iGuide listing (too bad). The Quick
Reference Guide for the 2007 Tacoma
(http://prg.toyotapartsandservice.com/pdfs/2007_Tacoma.pdf ) does not
mention octane requirements. However, according to Toyota
Reports...err I mean Consumer Reports , it also only requires regular.

I have a Nissan Frontier with the 4L DOHC V-6. The manual for my
Frontier specifically says regular is required but that for maximum
fuel economy and performance, premium should be used. I have
experimented with premium and have not been able to detect any
significant difference in fuel economy (I keep a detailed gas log).
Any improvement in performance is undetectable to me. Perhaps if I
used a stop watch I might be able to tell a difference, but then that
seems like splitting hairs. In the past the delta between regular and
premium gasoline was $0.20 per gallon (except for Shell that had a
higher differential for V-Power). Recently I have noted that a lot of
stations have upped the differential to $0.22 or even $0.24 per
gallon. Pure banditry in my mind.

The iGuide feature is a big improvement for Toyota. Too bad they only
cover a few models at this time. Hopefully the list will be expanded.
Other manufacturers have been providing online copies of owner's
guides for many years. I guess the big T is finally trying to improve
their Customer Service. They might even get out of last place one day.
Now if they quit running those ridiculously misleading Tundra
commercials......

And at least for a 2007 Tundra (and Camry, FJ Cruiser Highlander,
Avalon) it is free online at www.toyotaiguide.com.
