[ARCHIVED THREAD] - 2 cycle oil mix (Page 1 of 6)

all of my 2 cycle toys take a 32:1 mix. well today i got a new toy that takes a 50:1 mix. help me out motor heads .... will the new toy go T.U. if i use the 32:1 mix in the new toy?

Quoted:
The mix ratio is oil specific, not unit specific. Mix it according to what's on the oil bottle. IF i understand you correctly if you mix according to the package it will adequately lube a 32:1, 40:1, or 50:1 engine?? It has nothing to do with the engine requirements, just how much the oil mfg said to reach a certain lubricity point? Brian |
|
I don't understand, if your new toy says 50/1 why not mix it to 50/1? If you run 32/1 your just going to run it rich as hell and will foul plugs and smoke like shit. I'd run it rich for the first tank or two and then lean it out to what is suggested.
but that's me me. |

Mixing too much oil will cause an engine to melt down. 2-cycle engines require fuel-splash for cooling. More oil = less fuel. |
Personally, if an engine manufacture says he want one part oil to 50 parts gas, I mix it that way. And if he wants 32:1? I mix 32:1 and maintain to cans. The engine manufacturer knows what he designed and tuned the engine for, follow his recommendation. You may need one of these. ETA: I need a linkable picture

A fuel mix at 50:1 will flow more through a given carburetor jet than a 32:1 mix due to the lower viscosity. Just follow what the manufacturer recommends and as been posted there are different oils for air and liquid cooled engines.

You are not making any sense. I hope you are saying if it wants 50:1 read the label on the oil you are using and mix it 50:1 per the instructions on the bottle. If it want 32:1 follow those instructions. If the engine calls for 50:1 it doesn't matter what oil you are using you still mix it 50:1 |

I actually spent a week in Virginia Beach at the Stihl factory school getting educated on this very subject.

What toy?
50:1 is common for some motorcycles like this Husqvarna WR300. http://motorcycle-specs.com/motorcycle_specification.asp?manufacturer=Husqvarna&model=WR%20300&year=2011 Things can get spoogy. |

Quoted:
That is 32 parts gas 1 part oil all jetting being the same if you run that in a 50-1 you are not getting enough gas.This causes a LEAN AIR FUEL mixture and you could and probably will sieze it!!! Yup. The ratio is determined by the lubricity of the OIL. |

I would highly recommend using the oil type and ratio specified by the engine manufacturer.
I make a living designing high performance 2-stroke engines for an OEM in the powerports market. There is a VAST difference from one 2-stroke oil to another. OEM's work closely with oil vendors developing custom blends for thier oils to best suit the needs of a particular engine. THe process involves a lot of testing and development work. We test literally hundreds of different blends before coming to a decision. Some fail incredibly miserably...even some commonly available "name brand" type oils that make outrageous claims. |

I just use the universal mixture packets. It does not matter the ratio the equipment calls for. One packet to 1 gal gas, use in all 2 cycle engines.

But its not like every kind of machine is listed on the bottle so if I have a boat motor thats a really old off brand, old enough to require lead additive where do I find that on the bottle? Get my point yet? |

You have it backwards...50:1 will run more RICH than 32:1. More oil in 32:1 (less gas) than 50:1 (more gas ,less oil). I run all my two stroke dirt bikes at 32:1. They might smoke a little, but the internals last for a long time. When Honda was racing their CR250s...I read that they were actually running them at around 37:1. They must of known something that I do not. BTW...with current electronics...I have NEVER fouled a plug. Protect your shit...:-) |

I don't understand how a motor can call for a certain given mix, and then you can just use whatever the bottle says for another given mix. The last bottle of oil I bought broke down several ratios. How is it that I can just pick one and go with it regardless of that the manufacturer's suggested ratio is? Heck, you could pick any ratio you want and slap it on a bottle.

Guys, I always just mix at what the oil bottle says. The stuff I have says 32:1, so that is what I mix at. ETA: I never knew it mattered what the mfg said. ETA again: Oops, I see James does the oil bottle recommendation.......WHEW!! ALL 2-cycle engines are created equal. Same clearances, same needle bearings, same skirt clearances, etc. Hell, most even share carburetors. These factors determine mix ratios. Now, since they are all the same, it boils down to the oil. Keep in mind, we are not talking liquid cooled motorsports application 2-cycles. |

ETA: All I got left is Stihl oil bottles and all they say is to mix the contents into 2.5 gallons of gasoline. (I must have used up my generic brand stuff.) |

I think so, 6 ounces plus something. You know those little orange Stihl 2 cycle bottles. ETA: 6.4 ounces. I guess that would be around a 40:1 ratio? |
| I am a chicken. I use Echo oil in my Echo devices and Stihl oil in Stihl devices. I know it is an over kill, but then I still am running a Stihl 0S8 chain saw I bought back in the 70's. It starts every time and has never failed me. Granted I do keep up with things such as cleaning the air filter and such. BTW, they are not garage queens. |

The bottles marked mix with 1 gallon, 2.5 gallon etc. just make it easier for small motor owners. You could use the same oil and mix it to what ever ratio you wanted. Math is hard for some folks. Yeah, but the bottle doesn't tell you to do that. By that I mean, it gives a specific "recipe". So, when I fill a 1 gallon gas can, I just portion it out but use the same ratio. You get what I mean. |
