Thank you Fred for your suggestion to preserve the data on inexpensive lubrication.
Here’s an upgrade, or summary, of the data I collected:
1 - The fully synthetic motor oils work on plastics as well as oils used in the food industry. It so happens, the most available to us are the motor oils – Mobil One motor oil is most cited along with their Mobil One Synthetic bearing grease. There are other choices.
2 - Thanks to Mark Hadler’s contribution (above post), one excellent application method is using the 1 ounce “Needle Oilers” sold by Brownells @ $11.99 for a package of three. They are easily filled with synthetic oil. The closest comparison are the LaBelle oilers. The part number for the oilers at Brownells is 084-000-127WB. Just Google Brownells and fill in the “search” box with “needle oilers”. I ordered three sets - a late Santa delivery for several committed LGB oil users.
3 - Be sure whatever product you use is fully synthetic - which translates as plastic compatible. Again, I use the 15/50 weight Mobil One because it appears to have stick-to-it capacity on the wheel axle ends and on the internal gear shafts within the motor assemblies - that also includes a small drop of oil on the shaft exiting the motor housing to lube the sleeve bearings on the motors. The gear teeth get the grease.
Please continue to report your experiences.
Thanks,
Wendell
