What grade fuel do you pump?

When I purchased my 07 4.0 V6 Taco, the dealer did not mention anything about pumping premium gasoline. But I have read on a few sites that premium fuel is recommended/ required. ??? So what grade are you guys pumping for your 4.0 v6 owners?


Here is one of the links that says its required for premium gasoline.. (end of the 1st page)

Regular for me, never heard any knocking yet either. I saw that same thing you are talking about before I got my truck. A good buddy has had one for two years now and he says his runs fine on regular too.

 

Just regular, and in the winter every 3rd or 4th tank I fill with high test for cleaning properties.

 

mid-grade......and every couple of tanks, i'll run high-test. every oil change gets a bottle of techron for the gas tank.

 

reg. here, thinkin bout switchin to mid grade tho

 

All the numbers in your manual are in fact based on regular. however, the 05 numbers were based on premium, and it showed a somewhat significant bump in both horsepower and torque. So for me, considering that my tacoma is not my daily driver and most of the time (read as 7-8 out of 12 months) it had a trailer behind it, I figure I can spring for the premium.

Also, for what it's worth. I have run premium since I bought the truck, but since it is winter, and so no RV towing duty I figured I'd check out what some of you guys have said about mid-grade being better. So I ran a tank of midgrade on my holiday visit to see friends and family in Virginia, and here are my observations on that.

1. It did seem to show moderately better fuel mileage with the midgrade. That tank was 19.2 MPG (mostly highway) but I was stuck in bumper to bumper stop and go for not quite an hour in Delaware.

2. There was a noticible lack of power with the mid-grade. You may not notice it as much if you are used to running regular, but all I have ever known in this truck was premium, so I saw it right away. I had to downshift for moderate grades that I do not even have to downshift for in the summer on premium with the trailer in tow.

3. The premium does seem to show as being about 1 MPG worse but, I'll hapily sacrifice that 1 MPG to have the power I have come to know and expect from my truck. So I say if you can swing the extra 20 cents a gallon go for the premium, (or atleast do it when you are towing or hauling)

Those are my observations, I am not disputing what anyone has said, just offering up my oppinion. Quite litterally, you're mileage may vary.

 

ok mav, u convinced me to try premium. i fill up once every couple weeks on average so it'll be worth it if i see performance gain.

 

L Jackson,

Let me know what you think after you give it a try.

Also question about your listed mods... One nerf bar???? Is this a new style? Did you misplace one of them? Tragic rock crawling incident? This has the potential to be a really good story.

 

lol!!! i didn't know if i liked 'em or not, so i had one on for a few days and let everyone vote:

i went ahead and put the other one on today tho so i need to change it

 

Mid-Grade. I filled the first tank with regular but switched to mid-grade. I read somewhere that the compression rating on the V6 is right at the cross-over point (below 10:1, use regular, above 10:1 use mid-grade).

 

87 Octane here....truck runs fine so far.

 

2007 4.0 prerunner using 87 with 14k miles. No problems so far no pinging and getting about 19-22mpg on the HWY and 15-16 in town.

 

I'm not ever going to premium in my truck, from what I am reading It will give me extra power, which means I'll have to keep putting premium in there to get the power. Maybe I'll treat myself to a tank of premium on my birthday, enjoy the power for a few days until it's time to refuel LOL

 

I use mid. For me, thats 89. So far, I feel it works better than the Regular.
In my S10 I used to add things like 104+ or Lucas products Octane Boosts and Fuel Stabilizers - have not with the Tacoma. Not sure if i need to or should.

 

If you change your creepy avatar I'll buy you a tank of high test.

 

Since purchasing my Taco, I have pumped 3 full tanks , 87, 91 then 89. I could easily tell the difference between 87 and 91. It pulls a lot stronger with 91. But I dont think I could tell the difference between 89 and 91. So mid-grade is what I'll go with..

 

C'mon man just buy me a tank cause I'm a nice guy, I really don't wanna change my avatar LOL.

 

It costs me approx $156 a year to use premium instead of regular. Since $150 doesn't mean a whole heck of a lot to me, especially over the course of a year, I'll continue to use premium.

BTW, I did have some pinging when using regular when I first got the truck.

 

The company that I work for hauls bulk petroleum gas and diesel. Most all the mid-grad fuels on the market today meet premium specks. So a lot of times it is the same gas.
