Oh looks like the EPA actually phased that requirement out a long time ago (TL;DR: modern cars made them redundant), I guess there's just a bunch of stations around Seattle that still have em for some reason. Thanks Obama!

It depends on a lot of things. Those boots are related to vapor recovery. Most modern nozzles have a tube in a tube thing at the nozzle, to help with vapor recovery. I believe the boots were for before they went to the tube in a tube system, and were retrofits on the old style non recovery nozzles. I'd bet. Costco is cheap. I'd also bet nozzle condoms are cheaper than "modern" nozzles. I'll put money, that they're using the cheapest pump handles they can get that are legally ok.

One of the regional gas station/convenience store chains around here carries ethanol-free fuel in half of their stations so I'm never far away from that as an option. It's expensive as poo poo, but so is owning the bike.

A few rural stations carry ethanol free premium which is all I use for the dirt bikes. It's currently around $5.50 which isn't bad at all

I'm grateful that I have an ethanol free station nearby my house. Its more expensive but its only for the bike and yard tools.

At least up until this year, Shell's top grade was ethanol-free in Ontario, so I'd always do a full tank of it right before storage.

Lol and also lmao, I've been worrying for nothing. Shell and Esso (ExxonMobil) are the only ones with 98 premium around here, and a couple of years back the pumps suddenly had 'E5' markings on them. (And the national drivers assoc. ran stories with "No ethanol-free fuel available any more - vintage car clubs in shambles"). But reading Essos webpage just now, and paraphrasing, "we are required to mark the fuel with E5 for up to 5% ethanol, but we are going to put 0% in, don't worry". (Dunno what Shell are doing, they don't say either way.)

Is it in Esso’s financial interest to use ethanol in its gasoline? If so, I’d hardly believe their “pinky promise” that E5 is just a label.

Some percentage is good for both cars and plumbing. It stops water from pooling, same reason most brake fluid is somewhat hydroscopic. HEET? that fuel additive, is.. literally.. alcohol. So why 5%? Fuel is mostly transported in pipelines, and years ago they stopped using pigs to separate batches in the line. This means, each batch mixes a bit with the previous and subsequent batches. Even if they order 0%, there will be ~some~ alcohol in their batch. So there's no practical way they could sell actual 0%. And I'll bet that's why they had to put some "minimum number" on their pumps. Since we're talking about fuel. Most fuel is done in massive batches, and the differentiators are additive packages that each company chooses to add to their fuel. That 89 is probally the same 89 at every station in town, but Shell, Amoco, Sinclair are gonna have somewhat different additive packages.

There's a place near me with ethanol free but it's regular only :/ Does anyone actually know how much regular (presumably) you get out of the pump when you switch to premium? I'm a huge range coward on my bike so I'm always just adding like 2.5 gallons at a time

Arson Daily posted:There's a place near me with ethanol free but it's regular only :/ It's a bit more than a quart. Assuming worst case scenario, you're putting in 2.20 gallons of 91, and .3 gallons of 87, your fuel is going to be 90.5 octane. The fuel sitting in your tank for a week will affect it's octane more. Octane doesn't matter as much as you might imagine. Unless you're wrapping that throttle wide open all the time, you're probably gonna be fine. Most of the time the engine is running in an under vacuum situation, so the cylinder pressures will be lower, and you're not going to need the anti-detonation of higher octane. A point or two of octane rating wouldn't bother me one bit.

Cool I had no idea. I'm not all that worried about the octane since the tiger is tuned pretty conservatively and only "requires" 89 but it's a thought I have every time I fill the thing up

Do most modern bike engines use anti-knock sensors and the like to keep engines from actually being damaged in those cases, the way (I think) almost all cars do now?

so does a car engine, that doesn't preclude it from using a knock sensor to monitor the ignition timing.
|
# ? Nov 22, 2023 04:57 |
That's not what knock sensors really do. Your car isn't using the knock sensor constantly, it only uses it to pull back timing when the engine starts to knock. There will be some kind of learning aspect to it so it's not constantly bouncing off the knock limit, but that doesn't really change the fact that if you're controlling fuel delivery directly and regulating it for engine and air temperature, you don't need a knock sensor to run the most advanced timing possible. Cars have them as idiot proofing but they don't really help performance or efficiency or anything.

With the VanVan I wait until the fuel light comes on, and that's still only 1.2 US Gallons. I've had a small bladder my entire life and it's exactly like that.

Russian Bear posted:If I put higher octane fuel into the mt03 I get worse gas mileage. Higher octane fuel contains less energy, and it burns slower. So... if your fuel is burning slower, you're going to have lower average cylinder pressure. That means you need to run with a more open throttle for the same power. I'm not surprised.

I used to run 100LL avgas in a modified higher compression 2-stroke as cheap high octane gas. Oxygenated race fuel is MUCH better even in the same engine, let alone one built for it.

Basically every bike has an O2 sensor + cat nowadays, the majority of efi bikes have a MAP sensor from what I've seen. They're primitive in that sense, but they also have far more sophisticated systems than cars when it comes to improving rideability and response like secondary butterflies, showerhead injectors, variable length venturi systems and so on I worked on a Trident 650 the other day and was stunned when I pulled the tank off and saw an intake plenum terminating at just one TB like a car
