Since I've seen some older saws and questions on mix here lately I'd figure I'd show this off. If you look close it says mix with one gallon of gas. That's 16 to 1 by my calculations. It also says 30 wt.
Nice oil Rookie I have 2 old cans. Lawn Boy was from an old boy down the road who knows I am collecting vintage stuff for my basement and the Stihl can same from our own HittinSteel here! Thanks brother! The back of the Stihl can says to mix with 2.5 gallons. But only after 40 hrs of use. The first 40 hrs should be mixed at 1.5 gallons (25:1). The Lawn boy mix can shows several different ratios and how much fuel to add.
I have a few.....All of the round ones in first pic are full/unopened.Date from late 50's to late 70's. 2nd pic the Gear Case Oil ones date from late 40's to mid 50's 3rd pic single can was latest addition from last month -late 50's -early 60's empty
Not an oil can,but finally found one of these for sale 3 weeks back at a price that wouldn't break the bank.... Aluminum Mac-T Faller's Helmet,late 50's to late 60's vintage. They don't show up very often,think I've seen only 3 in the past 2+ years.Normally pretty beat up with lots of dents & missing paint.Did see a practically New Old Stock one back in early July - that sold for $110+
In the 50's & early 60's I just used 30 wt automotive motor oil and mixed it 16:1 . . . Never had any trouble. A lot of those old engines didn't have the bearings like they have today. I eventually went to 24:1 in the very late 60's - early 70's with specific 2 cycle oil. Now I use Pennzoil two stroke at 32:1 When I use up what Pennzoil I have on hand, I'm moving to Bailey's synthetic at 32:1 which I already have.
Yep. back when you just dumped a quart of 10W in a gallon of gas - and the mosquitoes fell to their death and you left a slick behind your boat If you really want to learn a bit about 2-stoke oils read here http://www.sea-doo.net/techarticles/oil/oil.htm I know it is for water cooled sea-doo's but the ashless/nonash and what has been added to create them is somewhat informative. If you get far enough(it's a tough read) you will notice Hydrazine is/or was once used in making the base synthetic - one of the very few chemicals my professors in college told me to stay the heck away from, it was used as an oxygen scavenger in boiler water - now has been reformulated/stabilized to only break down under heat/pressure in boilers. My guess is in the cracking of 2-stroke synthetics it is broken down as well....my guess anyways
