I am barely over 1000 miles on my new T4R.
I had pumped 89 (chevron) for regular fill-ups but decided to put 87 to see what happened.
At first, and this could just be my imagination, it felt as it had lost a bit of power than with the higher octane. I'm planning on going back to 89 (mid grade) in the next couple of days to see if I can feel any any difference. I am also loggin in my mileage to find any changes if any between the two octane levels.
Great thread... keep it going..

gas octane
i have 2004 v6 runner and i've experimented with all grades of gas.87 octane runs just as well and with the same mileage as mid grade or premium. i have never heard any knock,even under hard acceleration.i now run all 87 and i average 20 miles per gallon on a mix of highway and city driving.save your money and use regular.

"some 87 discount gas is actually bad for your engine. There are no detergents in gas from places such as Costco, Sam's, etc. This will lead to varnish deposits in your intake."
Where did you come by this info....is it here say or fact. I fill at Costco frequently and didn't know about this. BTW ,I use 87 only and truck runs great.

There was an article about this in the latest Car and Driver mag. Basically what it was saying was that there are a fair amount of contaminants in gas and that gas companies are supposed to add things to the fuel to neutralize the contaminants. The "top tier" gas companies always do this to their fuel and you will never need to worry when buying from them. However, there is no gaurantee whether or not some of these discount places put the right contaminants in. It is not illegal for them to leave them out, and they are not responsible for any damage to your vehicle from use. But the talk of the varnish and gum buildups from using these "lesser fuels" is real. So go to the top tier site listed above and check for yourself to see who has good gas and who has bad gas.........I hope I dont have bad gas.

Yes, but the trouble is that your manual doesn't tell you how much difference there is between the best and the worst.
I've yet to do an exahustive test, but logging the relevant OBDII data I've not seen a significant difference in ignition timing between 89.5 and 91 octane (two tankfulls each).
00328 said:I also have just over 1000 mi on my V8 and have never fed it anything other than 87 octane and it performs perfectly. I honestly think any higher octane is a waste except in maybe some instances like towing or something along those lines.
Just my very unscientific opinion.:
Your right and if you use anything above 87 octane your just wasting your money. These are not high performance sports cars. If I was towing near max over the rocky mountains then I might put the higher octane in but I doubt I would need it. Just use the cheapest priced 87 octane "Top Tier" gas in your area. But it is your money and if you don't believe what the experts have been saying then waste it, or you could donate it to a charity

I hate to tell you this but your wasting your money and a lot of those cleaners will damage your fuel system. Do yourself a favor and get educated on "Top Tier gas" and you will save money and have a clean fuel system. www.toptiergas.com
way to get gas cheaper
Hey to all, I would assume most or all of you have credit cards. I for one drive 78 miles a day to work round trip here in ther DC Metro area, so the price of gas IS a big deal to me. I use a AAA credit card and as long as I use it at the pump I get 5% off the purchase. It's the only thing I use the card for. Hey if you are already a AAA member or if you're not give it a look. (No I don't work for AAA). good luck to all, great thread. I use 87 in both my 4Runner and Tundra V-8's. CSM-H

I asked my local Sam's where there gasoline came from and they said the Murphy's Brand is bought from the cheapest vendor. Their gas was currently Exxon brand, just relabeled.
Re: way to get gas cheaper
You should get a Citibank Dividend Card instead. I've had mine for almost a year and you get 5% cash back on gas purchases as well as 5% cash back on anything bought at the grocery store. All other purchases are 1% back (with no build-up time like Discover). It adds up really fast. As a single person I accumulate $50 in cash back about every 2.5 months. Citibank will send you a check each time your reward reaches $50.

I am currenty researching OBDII to PC data logging, so I am interested as well as to what you are using. So far I like the ProScan & AutoTap systems. I will be purchasing soon. For me it must not be a hand held reader. I need it to store data on a PC so I can understand more about the sensors and draw plots and establish baselines.
