In my quest to add to my cluttered collection of power equipment, I have a new addition. I host a tailgate party for Kentucky football games and picked up a trailer a few weeks ago to set up for this. I set up a couple of deep cycle batteries and an inverter to run the stereo/lights/fan/heater....but went to Harbor Freight to pick up a new tongue jack for it...and ran across these neat little 800W two stroke generators they had one sale. Normally about $150, between the sale and a coupon, I was out the door for about $65. This is a Chinese made 2 stroke - weights about 40-50lbs - and amazingly enough runs like a champ so far. I took it home, fired it up, and let it run with my current normal chainsaw/trimmer/blower mix (fresh Shell 93 with Stihl Max Synthetic) and about a 400 watt load to test it out. I did some reading overnight and found out the cheap spark plugs don't last, so I tossed a Autolite 64 in it, hooked constant 500-600watt load of lights/fan to it and left for a few hours. It ran for 5-6 hours until I got home on about 1gal with the Shell/Stihl mix. First tailgate was last weekend, I ran a box fan and a home style stereo off of it for about 7 hours (Shell 93 and the Stihl orange bottle dino oil, just because I have enough for about 15gal of mix of this laying around and want to get rid of it)and it looks like on this light load I only used about 2/3 of a gallon. SO on to my question - what type of oil would you use in this? It is air cooled, but unlike my higher performance, high RPM, two strokes, it doesn't seem to get hot at all. In my garage right now I have: El-Chepo "pro mix" that I picked up from Lowes on sale years ago and never opened. Stihl orange bottle (used to run this in my MS290 and FS76) Stihl Max Synthetic (now use in MS361, Echo blower, and old FS76) Echo oil that came with my Echo Pennzoil Premium Plus TCW3 (for 115hp E-rude outboard) What would your pick be, from that list, or from something I could acquire elsewhere? I'm looking for lowest smoke/smell since it's around people, then I guess low noise even though this thing is quite, then third protection...because really...I've got $65 in this thing, its neat, but disposable. Disclaimer: This generator is a toy only, not something I have to depend on - the house backup is one of the big Sams Club Black Maxs with a Honda motor.
