Oil in the gas

[hondajas]

The three wheeler I just bought ('83 big red 200), the guy who had it before me said that in every tank of gas he would put about a ¾ cup of oil in the tank. He thought it was good for them motors. Could this have harmed anything in the motor, such as a high carbon biuldup on the valves or piston? What do you think?

If it's a two stroker,than it's fine.I spose a little the first time is all right but repeated applications mite be harmfull.I would just run 93 octane in it all the time if i were you.Oil can also gum up the carbarator.Get in the jets and other places it shouldn't :shock:

[hondajas]

It's a 4-stroke, and I have already cleaned out the carb

Not too good to run oil in the gas of a four stroke, so if i was you....if it still runs fine....i wouldnt clean anything(dont fix it if it aint broke!), but i would run supreme with a bottle of fuel treatment for a tank or 2.

[edog]

Yes i new this.

[JoeSuzuki]

Well then you could always take off the exhaust and with a aircompressor blow air inside backward to remove carbon buildups.

[edog]

It would take alot more than compressed air to get off carbon.You could get residu off buy useing air, but anthing that's been there for a while i dought it.

I noticed that in it takes a while to get up to speed, the machine feels sluggish, might just be me, haven't driven any other to compare. Feels ALOT sluggisher than my Big Red 250ES

[edog]

The float is sticking.Have you tryed checking that.

[JoeSuzuki]

Why u asking for advice if your gonna comment every advice u get????? Just knock it a couple of time and then blow air backwards. The carbon buildsup will break in scale pattern and with a couple of knocks its gonna loosen up, and with the air some of it will be remove. You can always cook it on a barbQ but you have to be carefull with that one.

It was my father in laws and he drives Tractor Trailer and he drives slow. They call him the turtle. He only drove this truck to work and at the end of the week home. My truck was sluggish like that then I went on a long trip on the highway and after 2 hours of speeding it was smokin and crap then whalla it just stopped smokin and started rippin. Seems it just needed to be driven hard and fast to burn out all the gunk.

I'd love to see that ha ha Ya you should use a lighter to get rid of the extra fuel in the gas tank.That's the best way to do it Right!

It wont really harm anything, but there is no benefit to him having done that. Its similar to running low rgas oil ratios in a 2 stroke. It may cause carbon to build up faster than normal, and may cause exhaust deposits to accumulate faster, and silencer paking to saturate faster. Start running regular gas, and dont worry about it. Most of the added deposits if there are any will begin to burn off anyways. There is no need to flush anything out or disassembler and clean anything unless after running a few tanks of normal gas, you still have excess smoke that just wont go away. Then you may have to replace packing material in the exhaust.

Tim, you don't think that extra 30wt oil might hurt his valve seats?.

[edog]

Don't you do it.Don't Make me take that away from you.
