I have lived several places all over the state and drive a good bit for work. I have been through your hometown before. Looked it up it is pretty much exactly where I thought it was, just down road from Joanna. Where the Nor board mill is for those not local.

And Cali lake Murry is just down the road. She must be a Lexington or Irmo area resident.

If yall get down here look me up!

Thats a good bit of oil. I was thinking i always heard folks say 150:1 or 100:1 your down there at 80:1.

I know it wont hurt it, i was just more thinking to save a little on 2 stroke oil. It wont matter for the tractor cause most of us use so little fuel in them but in a diesel truck you would be running quite a bit of two stroke oil.

that truck is about 40 gallons of fuel I pour in 6-8 oz per tank full. I probably only pour 2.5 oz ,or what ever size those small bottles of 2 stroke oil is

Oh ok you just saying like 8 oz in the tractor tank. I agree more wont hurt. Heck to get rid of old 2 stroke i find laying around or old clean motor oil i just dump it in the tank. To get rid of old oil bottles that i have laying around i will put about half a quart pert 5 gallons of fuel. Smokes maybe a tad more but not much. But 2 stroke i put one of those one gallon or 2 gallon mix bottles which is like 2.6 and just under 6 ozs i beleive. I will get an old one and fill it up or use an oil bottle with the clear stripe to measure since i have big bottles of tcw3 two stroke oil.

And thats another thing. Use water cooled engine two stroke oil or TCW3 oil. It burns more completly or better at cooler temps of a water cooled engine since its used for outboarss which run at a way cooler temp than ssy a weedeater or chainsaw.
