gas

Recommended Posts

Regular unleaded gas is all that is required for most ATVs except high performance ones. Unless it is stated in the owners manual or near the filler cap that you need premium, it will not make it run any better or start any easier and you spend more.

I beg to differ with you there. I have an 07 500 Sportsman, and it really seems to run better on the non-oxy premium then on the cheap stuff. For the $ difference on 5 gal of gas, its worth it to me.

All you need is the recomended octain for gas. The higher the octain the cooler the gas burns, which prevents "pinging" or predetination this melts pistons. You want the gas to burn as hot as possible without melting your engine. So if your run 92 or even 102 octain in a stock motor, the gass is burning to cool for your set up and your not getting all the BTU's out of it you should. Thus tossing your $$$ out the tail pipe. That being said I run super in my SP700. Not for the performance that I don't get from it but because it doesn't have corn in it. Corn gas has a nasty tendency to grow sludge in it and plug stuff up. Not to mention that the ETOH is also very hard on ruber hoses. If you do decide to run corn gas, you may want to run a mid range octain. I know in my owners manual it says to use a mid range octain gas if it has corn mixed in.

YMMV

Contrary to widespread belief, the octane rating of gasoline doesn't indicate how much power the fuel delivers; all grades of gasoline contain roughly the same amount of heat energy. A higher octane rating means the fuel is less likely to cause your engine to knock or ping. To avoid this, high-octane gas is formulated to burn slower than regular, making it less likely to ignite without benefit of spark.

The majority ATVs and such are designed to run on regular gas. High-performance ATVs and snowmobiles often require midgrade or premium gas because their engines are designed for higher compression (higher compression = more power), and regular gas may cause them to knock. If your ATV needs high-octane gas, the manual will probably say so.

Using high-octane gas in an ATV designed for regular accomplishes very little except more rapid combustion of your money.

It may "seem to run better on the non-oxy premium then on the cheap stuff", but actual dyno tests will usually show little or no difference in performance.

As mentioned most quads unless specified are designed to run on 87 octane. Any higher and you are just wasting your money. It may help to run higher octane when the quad has been sitting for a while, but if you have a full tank of fresh fuel 87 will do you just fine

Another fact is elevation......A motor set up to run 87 blend at or within' a couple thousand feet of sea level, could use 85 octane at elevations above 6000 ft. Less air pressure at higher altitudes, slows the burn rate down, So lowering the octane keeps you in the power curve.

Each motor if different, but if it's not pinging or detonating..... don't waste your money.

Gobaby, are those two sleds in your avatar Rupp's? I had one when I was younger and that thing would fly. I saw one just like I had at haydays in mint condition a couple of years ago.

Yep the one is a 76 Nitro 340 my brother gave me for my birthday, and the other is a 73 Magnum....The second one has the "racing use only" sticker on the tunnel, but has some other Rupp 440 in it..either way, both were free and run decent

The regular gas with ethanol in it is just fine if you are going to burn it up within a month or so, but I use the non-ethanol premium if I know that the fuel will not be used up right away. Ethanol will absorb water and turn to dump after a period of time. I agree that the premium does nothing for performance in a stock engine, but it sucks cleaning a carburator that is full of green goo.

    • Yeah, that kinda seems like what it should do with a 60hp motor.  What's a hefty dude?  Like 3 bills?   I'm kind of surprised a 60 is the max for the boat.  My 82 alumacraft is rated for a 60, same length but my beam is probably a foot and a half less.
    • Have you tried working with the tilt a bit like having it most the way or all the way down when taking off with a heavy load, then trimming it up more once on plane?  Even though you have the right prop there are other pitches you can buy for a better hole shot.  My 17' Starcraft with a wheel and windshield is rated for 125hp but pops right up even with 4-5 people in it with a 75hp Merc on it.    You might even try the ugly bolt-on trim tail on the motor.
    • Back home in Mizzura there was a little town that had a sucker festival on the spring.     They get scaled, fileted with the skin on and then the meat is scored.  Then they are breaded and into the deep fryer.  Apparently the scoring lets the hot oil dissolve the bones and it gives deep fried sucker a distinct look.   I thought they were pretty decent.  Once you deep fry the heck out of something it just tastes like deep fry though.
    • So that is still under warranty?   Do those lights run off a photosensor and come on automatically?  Could you pull the appropriate fuse so the truck would still run and not die until you can get it to the dealer?  
    • That is a lot of boat for a 60 hp motor, esp when loaded with 700 pounds of beef...     Another possibility, since the boat is new to you, is that the foam flotation has gotten water logged over the years.      It might be interesting to take the boat on the trailer and get it weighed someplace.    Compare the result to a calculated weight for boat motor trailer gas batteries etc.      Or maybe remove a panel in the floor and see if the foam is wet.     A few hundred pounds of water (I found one account where the guy weighed the soggy foam he removed and got 525 pounds) would make a big difference.     
    • I bought my first boat last September and I have a question about weight distribution. I was warned that it's a heavy boat by the seller, he called it a tank. In a good way. It's very sturdy in big water. So that's cool, but the first time I had a third adult hop in, the boat basically turned into a barge and just plowed water. With two "hefty" adults, gear and a cooler I have no complaints. It gets up on a plane no problem and scoots along just like you'd expect it to. Adding a third, non-hefty adult and gear was too much for it though. It couldn't get up on plane and the front end just plowed water.    It has a 24v trolling motor on the bow. The two marine 12v batteries for the trolling motor are also in the front, not all the way in front, but close. A buddy said he'd try moving the batteries to the rear. So what I'm wondering is, how much weight can you put in the rear of these boats and is this a good idea? Assuming they'd even physically fit. The main battery is already in the rear.    As a comparison, I have a 17' with a 60 HP 2 stroke and my dad has a 16' with a 50 HP 4 stroke, both tillers. My dad's boat slows down a bit with all of us in it, but easily gets up on plane and operates normally. His boat is a little more on the bare bones side and his motor is a good 10 years newer, but otherwise it's basically the same setup, but smaller, and it moves all of us around very well. This makes me wonder if my boat is or should be capable of more.    I also thought of the possibility that my old 1997 2 stroke is just tired (is that a thing?), but it seems to run very well. I also took it to what I think is a good repair shop and they assured me that I have the correct prop.    Here's all the info I can think of and a few pics.   1996 Alumacraft Competitor 170 1997 Mercury 60 HP 2 Stroke (60 HP is the max HP rating) 85" Beam (or close to that, can't remember for sure)   Try moving the batteries? Save up for a new motor? Or that's just the way it's going to be? Any advice from the community would be very much appreciated!  
    • Hello from the NW Angle! Areas of slush on trails in Minnesota are refreezing overnight and are still in good condition if well-traveled.  Walleye action is getting better every day, with mornings and late evening being best.  Rippin’ raps and buckshots are enticing violent strikes; 18-22 ft of water is key. Big northern pike are hitting jiggin’ spoons and tip ups with large baits. Anglers venturing into Canada continue to find schooled Crappies and big walleye deeper into 30+ feet. A slow presentation is most effective for catching crappies.  Until next week, Sunset Lodge
    • Yesterday the exterior lights under the side mirrors, all pick up bed lights and the tailgate light would intermittently turn on and go off.  I checked to make sure all doors were shut and checked all the lighting options in the vehicle.  The light issue killed my battery and it is very slow to take a charge.  Has anyone seen something like this?  I checked on line and didn't see any mention of an issue like this.   My truck is a 2017 Ford F150 Lariat with the 3.5 ecoboost.  I called the dealership and they said they could get it in the week of April 22.  A lot of good that is going to do me when the vehicle is dead.
    • Thanks guys, looks like I need to give it a try!
    • Last summer my son caught a 30.5" walleye on a local lake. It was a hot day so we put it back pretty quickly. We decided to surprise him with a Replica. Fiber Tech out of Nisswa did an amazing job! Only took 6 weeks once I made the call. I will use them again.
