    I have the 2.7, so higher octane would be a waste of money. I use 87 octane from Chevron.

    I use the higher octane. We have the same engines that the FJ's have and they call for premium. They also get a 239hp rating as opposed to ours at 236. Just some usless info that I have learned on here.

    Our vehicles are also capable of retarding or advacing the timing. Allowing the trucks to run at their optimal performance reguardless of octane rating, however some have noticed better mileage with the premium.

    I run the cheap stuff. I have noticed if I pull a boat it will ping sometimes, so I went up to 89. As far as the cleaner gas, my buddy had a VW Corrado with a factory supercharger, it was required to use 92 or 93. When his charger finally bit the dust we put a turbo on it, the internals were no cleaner than any other engine I have been into and he ONLY ran 92 or 93. That's my 2 cents

    2.7L here with Shell 87. Anything else is a waste IMO.

    From what I've read, The 2.7 & 4.0L engines dont have anything over the norm for compression either. I could'nt see justifiying the 93 other then for a little extra performance gain like some noted above.

    I've only had my four banger a couple of weeks and gas prices are fairly low so I ran a tank of 93 to "clean it out" and now 89. From what I read elsewhere here at TW, and also from the comments here, there is no point in using anything other than 87 with the i4. On the other hand, there do seem to be some real if marginal advantages to using higher octane in the six.

    My last two cars have been an Audi A4 Quattro and a Subie six. The first, with its turbo, only liked premium and the Subie six recommended premium but ran mid-grade and in some remote areas, regular. So I got used to paying at the pump.

    The 4.0 V6 has an 10 to 1 compression ratio, and will benefit from the use of higher octain fuel. My tests showed an increase in mpg, as well.
    Some more info:
    http://en.wikipedia.org/wiki/Toyota_GR_engine


    The 1GR-FE is the 4.0L version. Bore is 94 mm and stroke is 95 mm. Output is 236 hp (176 kW) at 5200 rpm with 266 lb·ft (361 N·m) of torque at 4000 rpm on 87 octane, and 239 hp (178 kW) at 5200 rpm with 278 lb·ft (377 N·m) at 3700 rpm on 91 octane. This engine features Toyota's single VVT-i, variable valve timing, system and a compression ratio of 10.0:1. Inside, the 1GR uses a taper-squish combustion chamber design with matching pistons to improve anti-knocking and engine performance, while also improving intake and fuel efficiency. Toyota adopted a siamese-type intake port, which reduces the surface area of the port walls and prevents fuel from adhering to such walls. This engine has special cast-iron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block. With these special thin liners it is impossible to bore the block. In the event of cylinder wall damage (scoring, deep protrusions, etc), the entire cylinder block must be replaced. For increased block rigidity, the 1GR also receives a high temperature plastic insulator/protector, which fills the empty space between the outer portion of the cylinders and block material common to open deck engines. For increased cooling efficiency, the 1GR employs water passages between the bores of the engine. There are such 2 passages for each bank for a total of 4. This reduces cylinder hot-spotting and keeps combustion chamber temperatures more uniform.

    :eek:My bad, I was under the impression it was on the lines of 9:1. 10:1 i think is higher then Ive ever seen in a truck! Wonder if the math balances out or makes it most cost efficient to run the 93 rather then 87 in a 4.0?

    This topic also has me wondering what the people above 3000-5000 feet are doing. Any 85 octane users???

    I run Shell or Chevron 87 most of the time with no engine pinging. Now that gas is cheaper I'll pump it up to the mid grade stuff. I was talking with the Chevron owner today in town and he told me an interesting tidbit. He was talking about how its not always wise to fill up with the fuel truck there. Reason being that it stirs up all the crap in the bottom of the tanks that inevitably winds up there and could reach up into your tank. Could be a urban legend but seems logical. Take or leave, thought I would share.

    I'm remembering this one the next time i see the fuel truck! I would bet the older the station, the worst it gets too. I have stopped filling at most older station solley based on the reasoning that a handful of older tanks can leak water in, as well as obviously fuel out. Check out some old tanks that have been pulled out of the ground next time you drive by an old station (30 or 40 yrs) getting demo'd. You'll more then likely be quite surprised.

    ^^^ I bet I know behind my Dad's work they ripped out some old holding tanks and they didn't look to hot. I never fill up at Non branded stations cause they don't use some of the detergents and generally have some amounts of water in fuel as well.
