What kind of fuel do you buy?

[opendriver]

I just wanted to know what kind of fuel people are using

If one of the mods from the UK or some other parts of the world want enclude some more choices please feel free to do so

 

[SRV2LOW4ME]

The only thing that goes in my cars tank is Ultra 94 octane. 👍

Its what my baby loves.

 

[Syntax error]

95 octane. It's an old car so it needs all the attention it can get.


Edit: oh... and I almost forgot to mention I put some lead additive in as well...

 

[3-Wheel Drive]

For my car, regular. It's recommened in my owner's manual, and it's the cheapest type, and I can't argue with that.

 

[Solid Lifters]

The gas my car was designed to work with, regular unleaded (87 octane). Everything else is a scam, mostly. Unless you KNOW your car works better with the higher octane stuff. But, it shouldn't. All cars, in the USA, are designed to work with regular unleaded 87 octane gas.

 

[3-Wheel Drive]

Exactly, why pay extra for premium when regular works just as well?

 

[Kylehnat]

Some cars (upscale, mostly) require premium. They have sensors that dial back engine performance if you put "cheap" gas in it. Whether or not the engine actually needs premium to function properly (not likely) is a different story. Racing engines, for example, need higher octane fuels because they run much hotter, approaching the auto-detonation temperature for "normal" fuel. However, I don't think many street cars get close to this limit.

Yes, mainly car cars with higher compression. If you have "cheap" fuel, them it doesnt give the car that extra bang it needs.

In other words, cheap fuel=powerloss(in some cars)
In other cheap fuel=no difference in power and you save some coin!

 

[Matrixhasu77]

What kind of fuel do I buy? The kind that costs an arm and a leg every week/month. My truck uses 87 Octane.

 

[franz]

My protege needs 87 and my friend recommend to stick with it
but I spend more money using synthetic oil

 

[Gil]

Regular 87 octane for all the cars
#2 diesel for the Excursion.

Though I fill up a state away because gas runs about 10-15 cents a gallon cheaper in MO vs KS
In fact I filled up my Camry today to the tune of "way too dang much money".
Yet, I'm pulling down 30.9 Miles per Gallon. I still hate paying so much for fuel.
Glad it's $2.53 across the street from my job.
It's $2.69 around the corner from my house.

my '98 Explorer XLT runs horribly with 87 compared to 91. 87 is usually what goes in the tank, though. Is it possible that the engine is able to knock with 87 at idle? That's what it seems like sometimes... the engine just totally bogs at red lights and etc. Premium 91 gas eliminates this entirely, though.

I kinda get that with my car but its usually alittle after I start the car. It could sit there for awhile or a few minutes before starting it. I use 87 and my car is a '95 Olds. The mechanic over at my job said maybe a vacum leak.

I work at a gas station btw. I still laugh at people who get mad at us about the gas prices. We dont have any control over that. We change when we get a call from the oil company. I had a guy yell at me one time when I was changing prices out on the sign. He yelled "Price Gauger(sp)!" as he drove by in a car. I just laughed.

 

[G.T]

95 octane. My Dad refuses to pay more for the premium 97/98/99 because he says it isn't worth it. He hasn't even tried it out yet, so how does he know!

 

[kikie]

95. 98 is better but too expensive. Driving a 3.0 V6 in Belgium is cruel. I'm mad at myself for making this stupid buy (mistake). I've bee trying to sell my car for over a year but nobody wants it

 

[Jay]

Ultra 98 Octane (RON), not because I want better mileage or power but the car needs it for safety. (Damn quality Japanese fuels)

If your car was designed to run on lower octane fuels then the for difference its not really worth it.

Yes, mainly car cars with higher compression. If you have "cheap" fuel, them it doesnt give the car that extra bang it needs.

Sort of, in high combustion pressure engines a higher octane is needed to reduce detonation (pre ignition), if the ECU is smart it will try and retard ignition timing to reduce or stop detonation which will inturn reduce proformance. Low octane fuels in a high octane engine can increase damage and reduce reliability. So the main issue is saftey not power.

If the ECU doesn't retard ignition timing then you wont notice much of (if any) powerloss, put might hear some funny sounds coming from the engine.

I've amended the poll to reflect the different octane rating system in Europe (we use RON ratings, the US uses a more transparent system of PON or "Octane", a combination of RON and MON ratings). US 89 Octane is about the same as EU 95 RON, and the 91-94 Octane is about the same as EU 97-99 RON - we don't really get an 87 Octane (93RON) equivalent, but we do now get a 102RON petrol.

Thats why I indicated 98 RON in my post.

I wish we got 102 RON, how much extra do they charge over regular high octane?

We do have a few fuel stations that mix their own higher octane fuel for performance cars and BP used to sell 110 octane (RON) until the government banned it.

 

[Famine]

95RON = 94p/litre average
97-99RON = £1.01/litre average
BPUltimate 102 = £2.45/litre

No, not a typo...

 

[GilesGuthrie]

I run 5-8 tanks of supermarket-special 95RON, then 1 tank of Shell Optimax (98RON). I find that this cleans the engine somewhat and makes it run smoother. Gradually the engine degrades again on the cheaper fuel, and it needs a fill of Optimax followed by a sound thrashing.

Fuel's about 8p per litre cheaper up here.

97-99RON = £1.01/litre average

Wow ..... Well It doesn't matter if they sell it here then, it wont sell well at that price.

 

[Casio]

You can actually get 100 RON in Australia now mate. Although I havn't seen it at any servo I've been too.

By car pushing out it's 66kw actually requires 95-96 RON....

Yeah I have heard of Optimax but I don't think Shell sells it here in SA, maybe one servo.

 

[kikie]

Just a question. What about this: good or bad??

 

[Anderton Prime]

If your car doesn't require high-grade fuel to run properly, why would anyone buy the expensive stuff? Who can afford it these days?!

 

[Dave A]

I picked diesel because that's what the 306 runs on and I've owned it for a lot longer than my Bora.

 

[Famine]

If your car doesn't require high-grade fuel to run properly, why would anyone buy the expensive stuff?

It commonly has cleansing additives and, being more stable, can give a small boost in fuel economy at the expense of a slight drop in power.

On a typical 240 mile trip (one I do regularly), the increased cost of 4-5p a litre for 98RON Shell Optimax super-unleaded is actually offset by the increase in fuel economy for the journey over the regular 95RON unleaded, and it has a knock-on effect of slightly improving fuel economy and emissions for the next few tanks of 95RON due to the degunking additives.

 

[MistaY]

95RON = 94p/litre average
97-99RON = £1.01/litre average
BPUltimate 102 = £2.45/litre

No, not a typo...

What the hell £2.45/litre? Man thats expensive, I think i'm going to have to see if they do it at the local bp.

A couple of months back I was using the Tesco 99 ron stuff, because at the station I go to it was the same price as the 95 ron stuff. I didn't realy notice any performance difference, the only difference was that I got realy crappy mileage. So I just went back to using 95 ron after a while, if I can find a damn shell staion i'll try running optimax to take advantage of those additives they put in the optimax.

Oh yeah man I filled up on Sunday at a tesco and the 95ron was 91.9, which was wierd.

 

[Roo]

The cheapest we have, 95RON (89 Ocatane). Although having read this thread I might start sticking a tank of Optimax in every now and again.

 

[High-Test]

I run my car off of Thermolene, aka N-Propyl Nitrate.















Just kidding. I buy 87 octane.
