Sasho Report post Posted February 5, 2023 As it says, what viscosity would you suggest for slower operating machine. Thicker will be better for my adler 69? Currently have 32 and 22 so I was wondering which would be more beneficial for the machine Thank you Quote Share this post Link to post Share on other sites

I think Adler recommends DA-68 for your machine. I don't know what the weight cross over is for this oil. The 32 and 22 I assume you are referring to is ISO 32 and ISO 22. The equivalent SAE for ISO 32 would be 10W and ISO 22 would be 5W. Sewing machine oil is a 5W white mineral oil that has a light viscosity that doesn't accumulate on the gears of machine. In my own machines I use a blend of synthetic oils but I am willing to take all the risks of not using sewing machine oil that the manufacture recommends. kgg Quote Share this post Link to post Share on other sites

dikman Report post Posted February 5, 2023 I did some research a while ago and it indicated that the commonly used oil (Lily White) is a light hydraulic oil, ISO 22 or 32 (seems to depend on the manufacturer). I couldn't find that when I was looking and bought a slightly heavier hydraulic oil but it works fine. Don't get yourself into flap over it, either of those you have will be ok, I doubt if the machine will complain. Quote Share this post Link to post Share on other sites
Gymnast Report post Posted February 6, 2023 I have seen ISO 68 oil specified for some sewing machines as well. The number here refers to the viscosity at 40 C. You can get the same kind of white mineral oil up to ISO 150. Motor oil got some more additives, that you do not want in a sewing machine, and it typically have got a viscosity of about 100 at 40 C. A higher viscosity will make the bearings carry the load better at lower speed, but the loses and heat up of the oil may get unacceptable for higher speeds. If the machine have got an oil pump and some centralized systems to distributes oil around, then you should stick to what the manufacturer recommend. I use some ISO 100 oil in two of my vintage sewing machine, that I use for heavier loads and for lower speeds than it may have been designed for. The machine would normally use ISO 22. It is no big deal for you to alter the oil type with respect to your use of the machine. Quote Share this post Link to post Share on other sites
DonInReno Report post Posted February 7, 2023 The old factory machines I have probably sewed balls-to-the-wall 8 hrs a day, 5 days a week for 50 years on nothing but common ordinary Lilly white sewing oil. Oil it often and the chances of ever wearing one out are slim at best. Quote Share this post Link to post Share on other sites

In my area an old time repair guy uses transmission oil in machines when the owner wants the sewing speed increased to keep up with the operators to better get rid of machine heat buildup. kgg Quote Share this post Link to post Share on other sites

The synthetic transmission or motor oils have very little if any more odor then sewing machine oil these days. kgg Quote Share this post Link to post Share on other sites
