Stick 40

I am getting ready to mix my first batch of gas and oil for my Dle 20 and was wondering how close do I have to get it. Should it be over a little under a little, if its to be one or the other. Its hard to get it exact and if one is better than another I would do that.

I figure for a 30 to 1 , I need 4.3 oz of oil for a gal. of gas. Is that right? I am using Klotz oil.

thanks

When in doubt, go for more oil. That being said, Klotz should be synthetic oil. I have never mixed synthetic that rich, usually it is around 50:1 to 100:1. My advice, get some conventional oil and mix at the recommended ratio for the first 2-3 gallons of gasoline before switching to synthetic. This will allow your engine to break in properly in a reasonable amount of time. Synthetic oil is very good, but has too low of a coefficient of friction for proper break in.
Good luck

I use a good quality synthetic motor cycle oil at a ratio of 40:1 for my gassers.

Seems to work OK

Mix as accurately as you can. I always start out with an empty gas can, pour in exactly 5 1/4 oz of oil and then pump exactly 2 gallons of gas. Your ratio can be off slightly but you want to be consistent each and every time you mix. Use the same brand and grade every time too. The end result is your engine will run the same every trip to the field.

Use the ratio and type of oil DLE recommends for your engine. After 2-3 gallons you can adjust to what suits you best.

For my gassers ethanol free gas mixed with redline oil at 40 to 1. I break in using synthetic oil as well it takes longer to break in but does no harm.

DLE specs out 30:1 for the 20cc engine.

Get yourself a MixMizer, only a couple bucks at just about any hardware or auto parts store, or a graduated measuring cup from the kitchen section....

yes the DLE 20 is made for 30 to 1 and I am sure that's 4.3 oz of oil. I just did up a gal. and I am sure I got it just a little over, but not by much.

That tool looks great, I will get one. This time I went by the divisions on the quart and went just over the 4 oz line.

I thought the Klotz was the best oil , to mix for our gas engines?

Personally speaking now !! Everybody has their favorite oil, but I feel that KLOTZ is one of the best. Have never had a problem with Klotz in numerous applications.

Thanks for the second opinion , I have never used Klotz but have always heard it was the best. I don't generally go cheap with stuff like this. I know some go with other oil, but for now I will stay with the Klotz.

thanks to all

Still ultra mixed at 32:1 is excellent. I not only use it in all my rc engines but I use the same mix and oil for all of my lawn equipment.

After two gallons of synthetic Am-soil at 30:1, I change to 100:1. After several gallons the rings and spark plugs are as clean as day one. I also use regular pump gas with 88 octane on my DLEs. I have an OS GT 22 that I only use Coleman @ 100:1. When I saw several guys using Coleman@100:1 and saw their spark plugs, I was sold. The bad thing is Coleman is $9.95 a gallon. But it's worth it.

IMO, oil is oil. I have yet to hear of an engine that locked up because someone used the wrong brand of oil. 2 stroke engines have been ruined by not using any oil, but that's about it. The big difference is how much smoke you get and how much carbon build up you get. The synthetics can be mixed leaner (I use Amsoil 100:1) which means less smoke, and the inside of your engines stays cleaner. If you use cheap oil it will still protect your engine just fine, but you'll wind up with carboned up heads eventually and you may find that your carburetor gets gummed up sooner as the fuel sits in it.

"IMO, oil is oil."

Just like cars is cars. Doesn't matter whether its Chevy/Ford or Rolls Royce.\

There is such a thing as the right product for the right application. The manufacturers have put a great of money/time/research into what works best for what. Why would anyone throw away all that knowledge.

I have an article by the tired old man. He has written many many articles in magazines about all kind of engines. He is not a fan of 100 to 1 mix. He asks the question why go leaner on a mix, when more oil is better. In his opinion 50 to 1 is as lean as you want.
Just throwing this out there. I fly with 10 guys that are all gassers we don't use the same oil, but we all are 40 to 1.

I wonder if that tired old man uses a 4lb hammer for driving nails too?..

T.O.M as he was know on here is one of the most knowledgeable people on engines you could ever know. His people skills were always a little rough around the edges but he knows what he is talking about. Why push it to the limit on how lean you can go? These little engines are not the best quality in the world so why not add a little extra insurance, and go with more oil. I have 4 of these engines and they run very well on 32:1 (4oz to 1 gal) with no fouling of the plugs, etc. Use any good quality brand of oil and reg gas. I also like to add an additive that helps keep the alcohol in the gas from separating out.

100:1 scares me! I guess you could save a couple of bucks with that low of ratio....
40:1 Redline works great.

I was once sucked I to the Amsoil 100:1 farse too. It led to a quite expensive repair on a DA 150. Since then I have run several different brands at 50:1 and have not had any oil related issues. Find a quality Air cooled 2 stroke oil and follow the manufacturers recommendations. Typically what I see is 30:1 for engines up to 50cc, 40:1 up to 100cc and 50:1 for 100cc and larger. As always there are exceptions.

What kind of repair did the 100:1 oil mix cause you to need?

This or any graduated oil mixing cup from a motor cycle shop is a must have item. They are idiot proof. Use the brand and Mix DLE advises at least for break in then you can find a favorite. I use Klotz or red Line. I too don't like 100-1 and went to 40-1 with synthetic and 32 to one with oils like Lawn Boy.

Most experts and long time users of the DLE20 recommend 32:1. I could not stand the mess that made on my profile so I upped it to 40:1 and have been staying there. So far so good but I don't have a lot of time on my engine. The reason for the 32:1 recommendation is that the 20 burns less fuel, therefore less oil is delivered to the con rod bearings. Adding more oil will help lube the bearings better or so the theory goes. I just could not stand the mess at 32:1, it reminded me of my glow planes and the main reason I left those engines behind. 40:1 was a substantial difference in cleanup over 32:1 and it's the same mix as my DA120 uses so I can now use one can for all planes.

Try using ethanol free gas. I feel the engine runs cooler with a tad more power.
Neither my 100 or my 170 has ever had ethanol gas.

Since I have a 2 stroke YZ 125 dirt, I have 2 sets of Ratio Rite cups, that is the best thing you can buy, as it has multiple ratio markings in metric and us measurements.
