Any non synthetic air cooled oil will do.

Any kind of "dino-oil" . Do not use anything synthetic for breaking in an engine.

Stihl HP Ultra. I like long break in times. Never harms the engine. Dan.

I just started using Lucus semi-synthetic. So far I'm really happy with it.

Use the same oil and ratio as you plan to use for the life of the engine.

I agree with w8ye. Use the same oil and ratio for the life of the engine. Synthetic oil is slicker than dino-oil. The argument has been to use the dino oil for break-in as it would allow the ring to seat faster than synthetic oil. The early DLE engines were known to come with a very hard ring and therefore a dino type oil was preferred. However, I think the rings DLE uses now are somewhat different from the originals and so you may just choose the oil of your preference and stay with it. I don't think using different oils are really necessary.

Come on you know you can search. It's not the oil that's important during break in, any two stroke oil will work. It's how you run the engine during break in that's important.

use whichever oil you intend to for the life of the engine. MVVS is kind enough to provide a bottle of oil for the break in period, others are less kind so just. Go down to the nearest hardware store or motorcycle shop and buy the best oil they have. Mix according to the recommendation of the engine manufacturer.

Before first start up set the carb tuning needles to the recommended settings for starting and running in. On first start up allow the engine to warm and gradually increase rpm for about 30secs to about 1/4 throttle and leave it there for 10sec before reducing back to idle. Repeat this procedure a few times within a 3min period. Thereafter increase the throttle range during each 3 min cycle so that by the time you are approaching full throttle.

During this time you may want to tweak the needles it peak the engine rpm. If you do I suggest you find peak rpm but open the high speed needle just a fraction, maybe 5 min, to ensure there will be max fuel flow without affecting performance. This is just for added comfort during running in.

the procedure is similar as you would for a glow engine with the exception that you are using the throttle to alter rpm not the tuning needles.
the idea for the first tank full is to get a heat cycle through the engine. Thereafter the engine can be flown around the sky while maintaining only short vertical runs for another gallon or so.

The engine may now start to require further tweaking of the carb to achieve maximum performance.

Crisco oil sort of gives the exhaust that fried chicken smell. Probably because it will fry the engine.
