What Octane Do You Use In Your 4.0L V6?

scienceguy · 07-03-2009, 12:45 PM

Ok, I know this has been beaten down pretty good, but I haven't seen any poles that are engine specific. Obviously, the four and six cylinder motors are quite different, so I am not as concerned about what the 2.7 motors are running, because I think they are pretty rock solid with 87 octane.

I just purchased a 4.0 V6, and I'm not sure what I'm going to run. I would like to just put in 90+ octane, but there is obvoiusly an increased cost. I've read of 4.0 guys that have great luck with 89 as a happy medium and I've also read of guys (and gals, sorry!) that are just fine with 87. Toyota says 87 is good enough, so it is, but I just want to know what YOU run. If you want, let me know why! Thanks!

I run the highest octane avaliable at the pump. Always. Can't say I actually notice much difference in fuel economy. I do pay close attention to stations that add ethonal, and avoid them.

Brunes · 07-03-2009, 12:59 PM

The rating for the V6 engine has info/results for 87 and 91 octane. Better performance from the 91.

I use 91...93 occasionally.

Janster · 07-03-2009, 01:02 PM

87 here..... My commutes are day -to-day, nothing special. I don't need the extra (if any) gains from the more expensive gas. If I was taking a long trip and/or towing something, I'd probably shoot for 89.

rab89 · 07-03-2009, 01:25 PM

What do you guys think of the new "nitrogen" gas from shell?

Hoyal · 07-03-2009, 01:29 PM

I use 85...

rab89 · 07-03-2009, 01:30 PM

85 exists... please stop using it..

Hoyal · 07-03-2009, 01:35 PM

No Im good.. Ill still use it I get 20-23 mpg and its the lowest grade CO has we have 85 87 91. Everyone of my friends from brand new tacomas to the 90's tacomas all use it and I have not seen any problems. I used 91 when I had my WRX putting 300 hp to the wheels of awd turbo fun but 85 works for the truck just fine.

Yuma Taco · 07-03-2009, 01:52 PM

Tryed the higher octanes and at this time I did not see an increase in mileage per gallon. So I use 87.

I'd REALLY try and use what the manual suggests, only for the longest life of your truck.

Hoyal · 07-03-2009, 02:04 PM

I have ran 85oct in 2 of my vehicles that I ran well over 130k from brand new.

That's fine, I was just saying...

BTW, where all do they have 85 OCT at?

Hoyal · 07-03-2009, 02:13 PM

I know its better to use the better gas and what not but I have never had a problem and I didnt see a mpg gain using the 91 we have here so I went back to 85 to save some coin seeing how I use a tank of gas every 3-4 days.

Im in the Denver metro area of CO. But we have 85oct all over the state.

SC4333 · 07-03-2009, 02:43 PM

85 octane fuel should be fine in Hoyal's situation. As altitude increases, the need for higher octane fuels to prevent detonation decreases.

I'd say at a mile high hes has nothing to worry about.

Ah, gotcha. Didn't even think about the altitude issue.

EEtaco · 07-03-2009, 02:47 PM

I usually stick with the highest I can get at shell and avoid ethanol when possible.

dorifuto · 07-03-2009, 02:54 PM

93 isnt available in my area so I just stick to 91.

jandrews · 07-03-2009, 03:06 PM

91 doesn't exist here, so 93, if only for engine health.
