Need a Spot

This is on a 04 Tacoma SR5 2.4L Auto 15" tires.

Has anyone done the 87 Octane and 89 Octane Mileage test?

Also, does your 04 Tacoma get better Mileage on which?

I am in the 89 Octane run now.

Thanks

Save your money. Everything I have read and trying the 89 octane for years makes absolutely no difference. The fuel companies think so but in actuality your truck will run just as well. In fact it is designed to run on 87 octane rated fuel. Actually the octane rating really reflects the anti-knock properties. I do know that the only engines that benefit are super high performance engines that have much higher compression ratios. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Denver,

Thanks for your Reply. I Understand it is designed for 87.

The 89 Test did prove out to get Better gas Mileage.

Combo of 101.3 Town short trips Avg. 7.1 @40 MPH each and 134.4 Highway @ 60 MPH. Gave me 26.6 MPG. Big Increase over

87. This was run doing the same trips to the same places . As the 89 was. 22.2 on the 87. This Was Shell on Both.

Now that is Impressive to me. As well as a saving of 1 to 2 cents per mile. Cost Difference was 10 cent More per Gal. for 89.

Calc $ per mile and see for yourself. All the experiments I've done in the past said 'no'.

Well, I guess if the numbers work, then more power to ya. I wish I got great mileage like that. I couldn't get 22mpg if I drove downhill everywhere I went. <img src="/forums/images/graemlins/shiner.gif" alt="" />

Don't forget the 1st mistake most people make when calculating MPG. Most will fill their tank, calculate MPG from the miles they drove on that tank. This is wrong, you need to wait until the NEXT fill-up to see how many miles you drove and then figure MPG for the previous tank. Otherwise all your calculationa will show data from the last tanks fuel grade and be completely innacurate. Did that make sense? <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/drunk.gif" alt="" />

I have about 2 1/2 years data on my '04 4x4 SR5 V6 TRD fill-ups and my best mileage is mostly achieved with regular (cheap) gas.

Higher octane is designed to essentially burn slower and at a lower temperature. So in an engine that is not high compression (e.g. the Tacoma) higher octanes can actually finish burning fuel while/after the exhaust valve has been opened. This isn't really harmful, but it can cause a reduction in power and in MPG.

I would honestly like to do more testing with my Taco and different octane levels, but with the high gas prices I think I'll stick with the cheap stuff which works just fine. <img src="/forums/images/graemlins/cheers.gif" alt="" />

I Agree what you said didn't make sense. lol

Fill up, run it, fill up, get gallons, get Mileage.

Now / that and,,, that is your mileage
