Is 93 okay?

 

Hell yes. 93 is even BETTER!

As a test, a member hooked up a knock monitor and observed pinging. He mixed 100octane with 93 to make 96 octane which completely got rid of knock.
Since our engines are high strung(thanks to our high compression rate of 11:1) our cars naturally knock with low octane.
The higher the better, but there is also a limit to how high you can go.

 

you don't have any shell gas stations in mont county?

i use shell vpower93 everytime i fill up.

always use 93 if you can

 

Agreed. I wish I had realized our cars were 11:1, I had 92 octane when I was on the dyno. I'll start getting 93 from now on. Some stations around here have 92 as "premium"... sneaky bastards.

 

btw, that member that tested this is I hate cars.

 

premium all day i used 89 1 time with my 06 tl and def felt the lack of power never again after that ..and i def say if you have a shell station that's the way to go ...i stopped using bp a long time ago..i only compromise with mobil if i can't find a shell

 

yes 93 is better!!

wish we had 93 out here

 

I think our cars are secretly race car wannabe's. They love racing transmission fluids, really high octane gas, and performance mods

 

I live in Fairfax County. If you have any Sunocos near you, they most likely have 91 octane and it will cost 2¢ a gallon less than their 93 octane (Sunoco uniquely sell four grades of gas—87, 89, 91, and 93; the price on the sign is usually for 93). But as others have said, there's no harm in using a higher octane than required, and it's definitely not worth driving out of your way just to save 2¢ a gallon by buying 91. Consider that on a 15-gallon fillup you'd be saving 30¢. At about $3.72 a gallon (which is what I paid the other day for 91), the 30¢ would likely be burned up in driving to the station if it's not right on your route.

There's a Wawa on Optiz Boulevard in Woodbridge, east of the turnoff for Wegmans, that sells 92 octane. It's the only station I know of around here that still sells 92. 92 was the norm when I got my driver's license (93 was pretty much only at Exxon back then), but 93 became the norm in the 1990s.

Either way, I use Sunoco's 91 fairly regularly because there is a Sunoco located close to my house that tends to have the best prices around this part of Fairfax County. My TL (and my wife's RSX Type-S) runs fine regardless of whether I use the 91 or the 93, or for that matter the Wawa 92. I do buy Shell when we have enough Giant points to get a discount, but since we don't normally shop at Giant, that doesn't happen on a routine basis.


Edited to add: Just want to clarify the bit about "the price on the sign is usually for 93." All the Sunocos I've seen list three grades of gas on the sign you see from the road: 87, 89, and 93. They may also list the price for diesel. The absence of the fourth grade from the sign doesn't mean they don't carry it, as just about every Sunoco I've visited in the Northern Virginia area has the fourth grade (91) as well as an option when you get to the pump. (I try never to buy gas in Maryland or DC because it's so much more expensive, so I cannot confirm as to stations there.)

 

Good grief, another question that is answered in the owner's manual!! (pg 164)

 

 

Ooops

 

Thanks guys.

 

I thought 93 octane was the normal "premium" octane fuel (atleast around Chicago it is). Humm I guess some places only offer 91 as the premo.

 

Incidentally, FWIW, the main reason cars designed to run on what used to be called "super unleaded" normally specify an octane rating of 91 or higher is that in certain areas, 91 is the highest octane offered. In the Rocky Mountain states the octane levels for all grades are generally lower (for example, at the stations near the airport in Denver you'll find 85, 87, and 91), apparently because of something to do with a lower octane being fine at a high altitude. In California apparently 91 is the highest octane, but I don't know why.

 

So is BP gas bad for our cars?

 

is BP gas 91+?

if so, then no its not bad.

 

^^^fixed

 

lolololol nice

 

 

Welcome to california.

 

avoid bp gas, it will blow our engines to smithereens.

 

@ smithereens.


And @ Charlie Brown. nfn^2 you need to save that for future use.

 

Thank god I don't live in California. The gas over there is $1 more than it is in Texas.

When gas was at $2.40ish in the summer (Texas), LA and there gas was over $3.40 for Premium! RIDICULOUS!

 

BP is bad for the environment and for people's lives. The gulf is still suffering despite no more press coverage.

BOYCOTT BP !!

We have a 76 that sells 100 out of the pump for $6.70 a gallon. He was holding steady at $5.99 until about 2 weeks ago.

 

Octane level aside, please make sure the gasoline is the recommended tier group.
Acura recommends the use of "Top Tier Detergent Gasoline," where available.

My TL drink only Shell or Chevron

 

BP is 91 around my way, but are you guys serious about avoiding and not using BP gas? I have been using BP for some time now and if it really is not the best for the TL I will switch. Just tryna learn ...

 

me toooo!

 

BP is Amoco and is fine for your engine. In fact, one of the member on this site wrote a little while back that it is one of the best fuels you can feed your engine. In my area, its grades are 87, 89, and 93.

If you use any of the major offerings, you're going to be just fine. I would avoid off brand stations because you just don't know what's going to be in their tanks.

 

It will make your car leak oil !

 

I don't use BP, but not for any moral or political reasons. I don't go there because the two near my house tend to run about 20¢ a gallon more than the Sunoco I mentioned in my prior post. (Also, one of them is on the wrong side of the road relative to the direction I'm normally heading.)
