Does Everyone Use Regular?

Mine isn't supercharged or turbocharged so I use 87.

 

Likewise, I started using Top Tier gas when I found out about it 2 tanks ago.

 

Holy smokes. If I have to see 1 more thread claiming better mileage/power out of a higher octane rating I might lose it. Please please please google what octane rating means. It has nothing to do with power content or cleanliness. It has nothing to do with being superior fuel despite the higher cost. People are trained to think more $=better. In this case it's false. It is a different measure of how it responds in an engine. To make it respond correctly for higher compression takes more refinement which costs money. Our tacoma compression just isn't high enough to make a damn bit of difference in this case.
Ethanol vs pure, yes. Different.
Tier 1 vs garbage, yes. Different.
Tier 1 85oct vs tier 1 93oct. Not different given a standard factory Taco compression ratio.
The internet. 95% of human knowledge at our fingertips. Lets put it to work.

 

Been running non-ethanol for over a year now.

 

so side question ethanol good or bad for our engine, I hear bad but not sure. Oh and give the reason for bad or good.

 

does a bear shit in the woods? lol 85 now that im in wyoming but could be why im getting crappy MPG's

 

You are a fool if you put in anything higher than spec'd in the users manual, there is zero benefit. It isn't going to do a stock truck any favors. Run the lowest grade octane spec'd and the highest grade fuel available. This means buying Top Tier Fuels from brands like Chevron, not that crap from AM/PM.

And as someone who requires premium, I never see it higher than $0.25 over regular. Well worth it for my extra 100hp. The ability to break the rear tires free on the freeway at 60mph in the rain and light up the traction control systems is worth every cent, every time.

 

Premium! Truck seems to run better and I get a little better mileage using premium.
And premium is less then .20 cents more then regular.

 

Agreed, though it is usually not intensional. I stated it as a datapoint for the relative real world power difference.

 

When I had my FJ I tried regular and got SHITTY fuel mileage. Switched to premium and ended up getting alot better mileage. So I just tend to run premium in all my rigs. .20 cents a gallon more isn't going to break the bank for me. I don't care to give regular a go. But that's just me, everyone has there own experience and beliefs on the topic.
If someone's on the fence on what to run, give each a try, at least a couple tanks and see if you boost any better results between them.

 

Premium here in southern California is only .20 a gallon more at most gas stations, I've never seen it more than .30 over regular. I have to use it because of my s/c, I guess the trend hasn't hit here yet (hopefully it won't)

 

Common misconception but not true, the detergents are not rated by octane. If it is a Top Tier fuel, like Chevron, then all octanes of the fuel are equivalent. The higher octane just has better resistance to detonation, which is needed in high compression or boosted applications. I specifically call out Chevron because when auto manufactures announced the new top tier fuel standards, Chevron was the only one to meet the standard without reformulating. Everyone else went scrambling to 'fix' their product.

In theory yes, you are correct. You should always run what the vehicle was designed for.

 

Cheyenne! Just moved there from Southern California

 

I'll definitely do that. I haven't met anyone since I moved there so it would be cool to meet some people and maybe do a little off-roading

 

what about ethanol treatment, to keep water absorption at a minimum?
