Now sold in a bunch of states... E15 for more alcohol and less crude. Approved by OEMs for 2001 or later vehicles. Not to be confused with E85 for flex fuel vehicles.

Around here, several Chevron stations have premium E0, but there's a little sticker that says "Not a Chevron product".
So it's premium and non-ethanol, but since I don't know what else it is, I haven't used it.
My 250 gets 91 octane E10 Chevron almost exclusively, except the couple times work gives us Maverik gift cards and I can't pass up free gas. I think Maverik is MD25. 25% mtn dew.

Silly boy, how little you really understand. Costco has ALWAYS considered their fuels to be one of its single biggest perks to members!!! 30+ years! Never seen it test poorly by anyone with proper skills
Redux of my argument last month.....prove the tuning is different>>>>>>mileage is the reason if no one else steps up with more proof for CAFE numbers.
Mileage likely has a lot to do with it, yet my average has stayed pretty constant since new. I can skew it for the better on longer highway drives, even around town if I optimize traction battery usage.
Yea, I will never use E15.
Very true, they say by topping it off you can ruin the charcoal/carbon canister that catches the vapors, official name escapes at this time.
Read the EPA fueling protocol please. Not the AI generated BS with Facebook posts added.................fill to first stop then fill at low rate till second stop.................................anecdotally effective for 49 years..........................that is difference from top off aka filling to the neck.
Filled up on the way home. $2.329 CDN per litre. This translates to $6.26 USD per US Gallon for anyone curious.
I’ve been reading this thread…
Lots of good info….But…
Even though most gas stations sell generic gas, they are still formulated with some amount of additives for wear protection. So, the stations that advertise as top tier gas selling their brand, are we paying more for what is really not needed to protect engine wear?

Idk. But The Motor Oil Geek did a YouTube video on Shell premium and how superior it was to other gasoline not to long ago. I won’t even try to quote his findings. But it was impressive.
Top tier status for major fuel companies is mostly about the cleaning additives. Shell appears to be the only brand promoting an additive specifically for wear protection in that niche.
Tier 1 is REAL. Superior detegent levels. ALL newer motors with any form of DI are much more prone to carbon buildup. Using a Tier 1 gas is 100% the best way to minimize this buildup, if not eliminate it.
I had a 2015 Ford Explorer Sport with the V6 Ecoboost. They're direct injection and prone to buildup but I ran it nearly 140k without issue. Always Top Tier highest octane available (usually 93, sometimes 91.)
Long term, the additional detergents in the premium gas are reputed to reduce deposits and wear (as noted in the Oil Geek video).
Short term, the biggest risk in using lower octane fuel is preignition, which can melt the aluminum pistons in a very short time. Retarding the ignition won't necessarily prevent preignition since a hot spot in the cylinder can cause it. It's mildly annoying that the LC manual specifies 91 octane minimum, but I can only choose between 87, 89, or 93. Whatever, I paid a lot of money for the LC, I'm not going to cheap out on gas.
I don't have any explanation why the fuel specified for a Tacoma/4Runner would be less restrictive - ordinarily, I would expect the higher octane requirement to be the result of a higher compression ratio.
My experiences with my 3rd gen Tacoma and 5th gen 4Runner indicated that using 100% gasoline or premium fuel did not provide an noticeable benefit above 87 octane w/ 10% ethanol, but I also do most of my driving near sea level (gulf coast area).

Although I pretty much run Chevron 91 (my area) exclusively, I will also run Costco 91 when I am in the area and will also run Shell
91. Shell is not really available as much as Chevron around my area, in Tucson Arizona. Unfortunately that all took a major shift in this area and many converted to Speedway.
If you are going to run a lower octane Chevron is a good way to go because Tecron is blended equally between all the fuel grades which is nice, while Shell premium only gets the Nitro+ additives for cleaning etc.
I have filled with 87 and 89 while traveling through California to keep cost of a fill up down when doing road trips. (The Chevron signs at gas stations saying high prices are the fault of Ca Government are real and quite funny) I really did not notice much of difference at high altitudes in Northern California in and around MT Shasta area.
It’s just my opinion that if you are going to run a lower octane than premium fuels, you should at least be running a Top Tier fuel of a regular/mid grade fuel. I think that will be imported later in your engines life to keep deposits at the minimum. Deposits will
Definitely degrade performance later in the engines life. To me it’s just worth the little extra cost as time goes by. People are going to definitely be limited by availability of fuels/brands and the additive packaging in their area.
I liked Texaco, Exon and Union 76 for years also and hardly ever see those stations.
Also good for thought and a station you might think is Top Tier because of NASCAR promotion is SUNOCO….it is not so don’t be fooled by the brand hype if you are seeing that.

I've put 93 octane in my LC250 except for two weeks while I was out west and only 91 was available. Anyone in here out west where only 91 (or lower) is available? How has it been?
Just over 15,000 miles of road trips traveling from Arizona (I live in Arizona)and travel frequently between California, Nevada, Utah, Idaho, Washington and Oregon.
All these states the primary premium octane grade is no higher than 91 at the mainstream gas pumps. I am sure higher octane can be found but would be limited.
I have not had any issues, I primarily run Chevron premium.
Probably the timing is different. Our 2nd gen Tacoma took 87 octane but the manual said you could switch to premium for the most HP for towing. I remember the guys talking about the timing adjusts after a couple tanks of the premium.
No, not "sorta". Toyota, the manufacturer states to use "premium" (91 octane) fuel.
Seems pretty simple.
