My engine is the 2 stroke Zenoah G43-L 41.5cc (GSR40 engine)

I read these babies can rev pretty high. Just a high revving engine overall..

I am torn between Klotz Super Techniplate 40:1 or Amsoil same ratio....

A asked a buddy what he runs his china (HT) engine with and he responded:
"Opti-2 100:1"




Maybe certain oils work better with different RPM's?


Hmmmn decisions decisions.......any insight on either of deez oils?
 
Right now I'm using whatever fully synthetic oil is cheapest at 32:1. Going to pick up some Arnold's 50:1 at sears. I did just order some sample packets from US2OIL (same stuff as opti-2) for $1.79 a piece - going to give a 75:1 mix a shot! :eek:

edit: Here's the the link to US2OIL. I couldn't find Opti-2 anywhere near me and they had the cheapest single packets I could find. One packet is one gallon @ 75:1

Double edit!! You can get 6 3.2oz bottles of Spectrum oil at sears for $3.29. Looks like the deal ends today! http://www.sears.com/shc/s/p_10153_12605_07136552000P?prdNo=1&blockNo=1&blockType=G1

I use whatever 2 stroke oil that i happen to buy. right now i am using a full synthetic oil made by Gumout.
 
When I was running my GZ23N14 "Geo or Strato" 25.4cc engine from Zenoah I was using Redmax syntheic 50:1.

I never had any problems with it for many years, the engine was ported and polished with a Hipo carb and exhaust.

I did seize the engine when I took a steep grade hill (downhill) about 44.7MPH..

I think the engine over reved and that brought me to the suggestion that certain oils may protect better against higher revving, hotter engines.

I would also think that since Redmax is Zenoah that the Redmax oil would do just fine, but may need to be mixed at 40:1 as per the G43's spec recommendations.
 
Next time I hop on a 2-stroke, I will likely run the cheapest oil I can find at 16:1 for break-in and 25:1 thereafter.
 
I use 5w30w synthetic blend and buy what evers on sale when I need it. As long as its a quality known brand.
