Portable 2 cycle lawn equipment ratio

[ledslinger]

Is there a mixing ratio that will be pretty much universal for recent chain saws, weed whackers, and leaf blowers. I notice many manufacturers say to use one ratio for their oil, and a higher mix of oil if you use anything else. If I use a quality air cooled 2 cycle oil can I mix it at the same strength as OEM oil, or still follow their suggestion to mix stronger?

I've got a couple of gallons of Motul 510 FD oil I'm planning to use in my 2 stroke lawn implements. Think I can mix it at the same ratio as Stihl says for their oil in my chain saw?

I'll play Mickey the Dunce. What is Motul 510 FD ? If it is a 2 cycle mix oil. I mix it at 32:1 If it is any other type of oil, I wouldn't use it.

 

[ledslinger]

Thanks Mickey, it is Motul motorcycle and scooter 2T technosynthese oil.

Is there a typo? Do you mean 500 2T 2 stroke oil.

This is a very good oil, one of the very best. I'd start at 50:1 and keep an eye on the spark plug.

I use Red Line 2 stroke racing oil at 50:1 in my Echo weed whacker with excellent results. It's over 10 years old with no problems at all.

For these applications I believe in using the very best oil I can find because you use so little oil over a long period ot time and I don't want to replace my Echo with a new one that has to meet current EPA requirements. The local landscapers are rebuilding old ones to avoid the problems they are experiencing with the new models.

I use 40:1 in everything.been using that ratio for 30 years

40:1 or 50:1, if the equipment is newer and from a well known brand I wouldn't hesitate to use 50:1. Older stuff or imported stuff I'd use 40:1. Functionally the lubricant should work just fine at either ratio.

I use Echo power blend in my old and newer OPE at 50:1...never a problem and and easy to find. Home Depot sells it.

Two strokes are not as fussy as many believe and will run fine on a variety of mixes. I generally go by the oil I am using rather than the actual equipment manufactures ratio. I go 32:1 on regular petroleum two stroke oil, 40:1 on synthetic blends like Yamalube 2R and 50:1 with synthetics. I've never lost a engine and run everything on the same oil.

 

[Mike72]

Two strokes (except for racing engines) need only a small amount of oil to function properly. Too much oil in the mix only increases the oil build up in the crankcase leading to more carbon/smoking and gains nothing. With today's oils, ratios around 50:1 are best with some synthetics going even higher.

 

[lars11]

I have not seen a oem recommendation of anything else than 50:1 or 100:1, at least not for 25 years

 

[ironman_gq]

The bigger problem caused by using different ratio's is in the carb, more oil means less fuel and the engines lose power, run hot, and lean. I've run 50:1 in everything I own but I do check the carb adjustments to make sure it's running right.

Oil build up in the crankcase? Really?

Do you have any idea of what goes on in a two stroke engine crankcase? Believe me, there is NO oil build up going on in there. With the furious speed of reciprocating parts and violent flow of air/fuel mixture blasting through, nothing is settling or building up in there.
Nothing wrong with 40:1 ratio. It's my preference for everything other than liquid cooled engines which get a little less oil.

In a liquid cooled power valved MX racing motorcycle I am using Opti-2 at 100:1. However, I am not racing it or riding tracks. Slow woods riding only and very occasional very short full throttle runs. Most of the time navigating the woods in first gear.

Great oil. Increased performance and nearly zero smoke.

X2. No build up happening. Two strokes are supposed to smoke. They burn oil. If you don't want a smoker buy a 4 stroke.

 

[ironman_gq]

Most 2 stroke OPE shouldn't smoke after warm up. If it's smoking it's either got too much oil or the carb is way off. Modern oils are designed to burn pretty clean and not leave a bunch of ash behind. I've got a whole fleet of 2 stroke equipment and none of it smokes.

I tend to go by the bottle or anywhere between 32-50:1 ratio.

Respectfully disagree. Oil builds up in all two stroke engines especially at idle and lower rpms. The amount of this build up is directly related to the mix ratio. Higher ratios of 50:1 and up minimize the build up.
