Shell 93 v-power and my imagination, maybe,

guys I swear my truck runs better when I use 93 octane. With low octaine at low rpms my truck feels like it stutters and “breaks up” when giving throttle. But with 93 I feel a smooth pull from 500 rpm all the way to redline. Guys am I imagining this or am I putting my money to good use?

Truck has CAI, urd y pipe, trd catback.
No OV tune.... yet

 

I recently started using 93 to see if helps with the 40-50 shuttering in 6th I’m experiencing and because I was noticing some very light pinging on 87. Too soon to say for sure, but it seems like there’s been a noticeable improvement in the 6th gear shuttering.

 

Try non ethanol.

 

of course it does. for what, $3.00 a fill up? I've never used "regular" gas unless it was to top off an rental car.

 

You’re not imagining it. Mine is the same way. Slight miss/stutter feeling and more vibrations / resonance on 87. I run nothing by shell 93 as a result...

 

I just recently put 89 just to see if there was any difference and it's been two weeks and I have felt an improvement. Next I'll try premium. The truck just feels like it performed alot better

 

Same here. Switched multiple times between 87 and 93 and have confirmed that it always ends up running better on 93. Smooth pull, no stutters.

I read somewhere on the OVtune page that this engine detonates alot down low and pulls timing. Could be related to that

 

Non ethanol is even better.
On my car, dyno showed a nice smooth graph compared to 93 ethanol.

Remember guys....E10 gas has very short shelf life...about 3 to 4 months.
Ethanol gas is hygroscopic.
Moisture in tanks with ethanol will contaminate.
Because ethanol is alcohol, it absorbs moisture. It cannot be left in your tanks for months. When ethanol is contaminated, it has a really distinct sour smell.

 

Im glad it isn't just my imagination that the engine sputters when in high gear with low RPMs, like 65 on the highway. I figured if I posted about it I would see a massive post count of "lol u suck, u dumb" but to know Im not the only one makes me feel better.

Next fill-up Im going to try 93 and see what happens.

 

Non ethanol does most for me

 

Do you pay a premium for non ethanol? Around here it’s substantially more expensive. People only really use it for marine outboards.

 

I see an awd Prius in your future.

 

There's nothing wrong with e10 gas as long as it isn't used for long storage.
For daily, it's fine.

 

Non ethanol and 93 premium price is usually the same.
In Hawaii it is and there's only a handful of ethanol free stations.

Oahu readers:
Hele gas...Kalihi valley
Hawaii kai 76....Lunalilo
76 station ...King st. Mccully.

 

So it is okay to use the non ethanol gas in the 3.5, like the boats and lawn guys use?

 

To make thread like more meaningful, folks should also state whether they have the 2.7 or 3.5. Just sayin....

 

I have the 3.5L engine. I have used 93 and it does seem to make the truck more smooth and seems to start of the line faster. Haven't tried non ethanol. Going to try some soon.

 

Probably all in your head. I bet if we had someone fill up your vehicle without you knowing, you wouldn’t have any idea of the difference.

I’ve tried all different fuels and the truck runs the same.

 

that hasn't been ruled out, just nothing to do with octane rating.
