eww, so does that mean that 85 is low grade? I can't imagine using that, whew

theoretically you can make more hp with the lowest octane....(lower the octain, the faster the fuel burns) but increases the risk of failure.

surf4runner

is this correct? or did you mean 89? i cant even find 93 out here, best is 91 (unles you have a friend at the airport )

i use 87 all the time, least expensive, but NEVER arco=cheap.

CynicX

87 before S/C without any problems. I think it ran best on 87, thats what Toyota recommends anyway....

snap-on

87 with 10% ethonal as thats all we can get in STL area.

ive run the lamp oil stuff they sell out west before <cough 85 cough>

MTL_4runner

No, he means 98 octane (unleaded too!!!).
....it is crazy over there, they basically sell race gas at all the pumps (you can't get low octane gas, period).

I'm going to try this. I just got my 4runner, it has 14000 miles on it. I've kept track 3 times now. 1st was 20mpg, 2nd was around 18mpg and this last one today was 19.9mpg. So if this is true, I should see 21-22. I run 87octane from wal-mart... paid $2.06gal today

Thats my log to date, I think some of the numbers have been affected by pretty big changes in temperature. I don't even know if you can even read it like it is, but I couldn't upload a Excel file.

Edit: I just showed the Grade and the subsequent mileage. These figures compensate for change in tire size and are about as accurate as can be.

87 octane, mostly Costco gas. No cheap stuff like Arco, Thrifty, etc., etc.

I put the occasional "Lubro Moly" Ventil Sauber(valve clean), "Lubro Moly" Jectron(fuel injector cleaner), Or Chevron fuel injector cleaner every 2-3 gas tank full.

89 in the 4runner, 87 in the Taco.

kyle_22r

cheapest stuff i can find. just because it's a toyota doesn't mean it needs special gas. my chevy work truck, on the other hand knocks like a snare drum if you mash the gas unless we run 93 in it...then again, it's got a high dollar stroker engine in it...

98taco4x

87 here as well in a 98 tacoma 122,000

87, the higher grades are just a waste of money unless your motor uses it specifically, supercharger, or other high performance goodies. I look for the most inexpensive 87 octane I can find.

edikp

87; been buying it mostly at CostCo.

youngbuck

User manual says 87, but since I am high elevation (Colorado > 1 mi. high) 85 is just fine, and no advantage whatsoever going to 87.

toywheelin05

i run 89 through my 22re, it seems to like it better. my yamaha r6 on the other hand....i run 103 in that baby. cracks like a whip when u grab the throttle. doesnt even compare to 92 or 94.

4unner4life

I run 87 in my 3.4 and 93 in my honda cr dirtbike.
