Supreme Gas in an ATC

[piroguedog]

Has anyone ever heard of higher octane gas being a prob? I don't think so but this is a dispute between me and a friend of mine. Thanks.

[piroguedog]

OK, not one opinion out of all those views? This is a simple one. Help out a newbie, huh?

[Bryan Raffa]

Some bikes require higher octane..like race gas.. due to there modifications and compression..So I would guess it could be a problem for some people.

[Bryan Raffa]

Now running race gas in a 200m will do nothing for you .. is that what your getting at?

[piroguedog]

I'm talking stock with just supertrap muff and k&n. And what I'm getting at is wether or not running super unleaded from the gas pump is hazordous to a wheeler's health in any way. I don't mean performance. I just figure it is cleaner.

[Bryan Raffa]

I think the most performance you will get out of it is running a 93oct even then it wont be mutch.. but defiantly better than regular 87oct

So one vote for "yes it is safe".

A problem as in how..like loseing HP? ahaa!!! NO it will not hurt your bike!

[Bryan Raffa]

your good,, Now leaveing Alky in your bike... thats a NO NO Bad things happen.. it attracts water and will rust it solid and the Akly eats the metal and seals!

Well as I stated in my orig post, a friend and I have been arguing about various opinions we have heard about using anything other than regular in small engines. I have always used supreme. Outboard motor, 3 wheeler, 4 wheeler, weed eater.......he says he has heard from various people that you shouldnt do so due to some idea about it burning hotter and hurting the engine somehow. I was just wondering what yall's opinion was. Again we are not talking about performance improvements. Just engine life/maintenance.

[Bryan Raffa]

well yes it is kinda true .. most older engines required leaded fuel.. witch good luck finding that these days.. that was mostly back in the late 60's early 70's. I can remember my dad dumping lead additive in his old race sleds in the mid 70's. I run 93 in my boat,weed wacker, chainsaw..and If I have any old race gas left over, I don't hesitate to dump it in any one of them and burn it up..never had a problem with any one of them ..personally I think my weed wacker loves 112oct and klotz..:)

Thanks for the info..............

No, running supreme will not hurt your engine. But in most cases it's just not needed.

I know for some small engines, it is not good. I have a 2006 Yamaha 150 Four Stroke outboard on my bassboat. It is a 4 cyl. and I have been told by lots of people and my dealer and the owner's manual that you should only run 87. It has something to do with carbon buildup if you use the higher octane. I run 87 in everything. 3 wheelers, mower (commercial ZTR Exmark), truck. Unless you have a vette or Ferrari, 87 is all you need. Especially with gas prices the way they are.

Do a search on octance here on the forum and you'll find everything you need to know.

Stock R's compression ratio is only 8:1. Racing gas Above 93 octane will cause these bikes to run really rich, even jetting changes will not be worth the extra money for race gas. I can jet with the best of them and noticed decreased performance with race gas in stock 85 ' 86 250r's
92 or 93 pump gas and rejet 2x a day sometimes and you will be a happy man!!! 1 move up or down on the needle clip is like night and day!!!!

your good,, Now leaveing Alky in your bike... thats a NO NO Bad things happen.. it attracts water and will rust it solid and the Akly eats the metal and seals!


No kiddin?? Thats somethin I never heard before. But then again I'm not an Alky throttle junky like yourself!! LOL!!! YAMAHONDAMAN

[seddon]

i have seen many pistons blown apart bc of running that stuff

[SWIGIN]

a motor normaly makes the most power when useing the lowest octane with out pinging

[McDerry]

I don't think anyone realizes the the octane levels in fuel have dropped about 13-16 points over the last 30 years. At one point in time 100 octane was regular fuel. De-Leading the fuel made the significant drop to todays fuels.

[The Goat]

my uncle still dumps mothballs in his tank from time to time. i'm kinda curious as to what this octane boost will do.

pirogue, just go to that loves on 415 and get your premium. make sure to go to pump ten...as it's noticably faster than the others. lol.
