I have a couple of older Homelites: Super EZ-Auto and a 330.

You are watching: Homelite 33cc chainsaw gas oil mixture

I bought a bottle of Homelite brand oil and it recommends to mix 2.6 oz oil per gallon of gas (50:1 mix). Is that too lean a mix OK for these older saws?Also, any places out there you can get owners manuals for these saws (I"ve been looking on e-bay)?Thanks
Fifty to one would work just fine in your old saw. That said, the highest level of lubrication would come froma 32 to 1 mix with the same oil.
Homelite oil mix
I also have a Homelite 330 and a Super EZ Automatic (and a Stihl 041 Farmboss). I run them all on 32:1 and have been for years, using mostly Pennzoil two cycle oil. I think I had the Super EZ a little rich this past year, because it developed a lot of tarry residue in the muffler. Didn"t notice it until I serviced it up to store it for the winter. Gotta lean it out a little before starting on firewood next year. The 330 and 041 looked fine. Gene Gauss

Ratio
32:1 for the 330 is the right oil mix.The 150 will run just fine on the same but tends to like a little more oil,say 30:1
With the newer oils (any brand) you can run them at 50:1 or richer (40:1 is typical) if you want.Older richer mixes (like 24:1 or 32:1 or 16:1) was because of poorer quality oils. I have a 330 manual if you want any info I can look it up for you.

Ratio Mix
I agree with the advancements in oil quality,but I also take into consideration the quality of the materials and machining of the product.I too have 330 manuals,as I have 3 homelite 330"s.I am a Homelite fanatic and have several(approx 25 Different Homelite model"s,including 3 ZIP"s, 3 330"s, 2 360"s"2 230"s,several 150"s,and don"t know how many XL"s,and 2 410"s.Not includind the Mac"s and Echo saw"s).I realize the importance of proper oil mix"s and would rather tear saw down and clean the carbon out than replace a jug and slug.Not saying I am choosing the right path,but I have saw"s that are increasingly more and more difficult to find part"s for(of course now that I have found this great group and all the wonderful people to help me locate the parts that i need),so I try to err on the safe side of the ratio.Also I am a burn survivor from NAM (Napalm),so please bear with me if I don"t respond in a timely fashion.Am in the process of listing all the parts I have available so I can try to help as much as I can.
