2-cycle oil and smoke
It needs a TCW-3 rating - that's all.

Even switching to the Pennzoil synthetic blend (9.99 at Wally World) will reduce smoke a bit. -W "Camilo" wrote in message ... "Tom Treadway" wrote in message om...

Thanks, TT I've heard that synthetic 2 stroke oil will reduce smoke. I haven't tried it yet, though. |

Thanks, TT I remember as a kid many years ago!!!! ... if I ran out of 2 stroke oil for my 50 c.c. motorcycle, I'd swipe some of my Dad's lawn mower oil. Apart from a plug fouling up sooner than it should, I don't remember any ill effects. And, on a 50 c.c., any lack of performance is immediately obvious. I have also run weed whackers on marine grade 2 stroke oil for years with no ill effects. My understanding is that air cooled engines run way hotter than water cooled outboards, hence this oil is unsuitabe. Granted, I don't run machinary like I stole it, Apart from bearings, reed valves & compression on a 2 stroke, the crank seals are just as important because the crank case is pressurised on the down stroke. Running the wrong oil could degrade these seals, or fry them. It's no fun to completely split a motor because a $5 seal is cooked. One more factor. The exhaust system/porting on a 2 stroke is critical to performance and "economy". The wrong oil could well clog up both. On the bright side, your compression ratio will increase (adjust the timing). So why do I still run the wrong oil in my weed whacker .... because it very seldom runs above idle, and it's one less potential fire hazard to worry about (that extra can of gas). Besides, if it didn't like the way I was treating it, it would have quit 11 years ago. Safe Boating. As far as I'm aware of, most string trimmers, saws, blowers, etc. require TCW-3 oil. I've never used anything else either... what oil are you talking about? The pre-diluted brand-specific (Homelite, Poulan, etc) tiny little doses? I run all my 2 stroke lawn/garden equipment on TCW-3 mixed at 32:1 for longevity... had to free up the rings on my Homelite trimmer once in 12 years, it still runs as new... Rob |

Just a side note..... in an "emergency" (you define emergency) a straight
30wt non-detergent motor oil at twice the mix (25/1) will do the job. Shake well. -W "trainfan1" wrote in message ...

Any two stroke run at 50/1 TCW-3 has a very good chance of "OK".
More so if an "engine cleaner" is used as directed once a year. -W "trainfan1" wrote in message ...

Rob While I'm not claiming it makes a *meaningful* difference, there is supposedly a difference between the oils made for 2 stroke watercooled (e.g. outboard) and 2 stroke air cooled (e.g. weedwhacker, chainsaw). The air cooled engine, I've been told, runs hotter than the water cooled engine, therefore different requirements for the oil. That said, I generally run my outboard engine oil in the weed whacker.

I never got a straight answer as to why from Bombardier/Rotax, but their PWC engines (at least of the late 90's vintage I own, specify TC rated oil, not TCW3. In fact there is clearly printed label right the oil reservior fill that say "Do not use NMMA ashless oil." Rotax's private label is low-ash and is not NMMA TCW3 rated. But you can buy TC rated oil, regular or synthetic, at motor cycle shops. Only bring this us because these are unusual. As far as I know, Rotax was the only "marine" engine make out there that said DONT use TCW3. Though I think it comes from their PWC engines being ramped up version of their ultralight engines with water cooled heads. With all that said, I know A LOT of people that have run ashless TCW3 in Rotax engines without any trouble. I run sythetic TC rated oil in mine and the primary benefit is reduced smoke. |

The poster wanted an oil that produces less smoke than what he currently uses, which is Quicksilver Premium. I don't see how telling him to use the oil he already uses will result in reduced smoke. |

Ding, Ding, Ding! Kevin Noble, you're right for a change! I read the original post incorrectly. To Tom- I think you're already using one of the lowest smoking two-stroke oils available. I've tried all of the major brands and in my experience the Quicksilver Premium smokes the least of them all (even less than the synthetics). |

I've tried all of the major brands and in my experience the Quicksilver Premium smokes the least of them all (even less than the synthetics). For less smoke you need an oil with a large amount of PIB additive such as with Evinrude Ram oil, Merc Premium Plus, and Sierra outboard oil. Evinrude and Sierra smoke less than Merc Premium Plus, but any of the 3 will reduce smoking. Make sure your outboard is in a good state of tune, that the carbs are adjusted correctly, idle timing is right on, and that the thermostats are allowing the motor to warm up to around 140 degrees ( or what is recommended by the manufacturer). The August 2000 issue of Bass and Walleye Boats magazine has an article on the differences in various TC-W3 oils and it explains why "jetskis" and air cooled 2-strokes need metallic additives that could damage an outboard engine, it is due to the duty cycle of the various types of motors.
