Here's my stitch for the A10.
Engine: 20W-50 Castrol GTX, w/ a dab of Federal Mogul Assembly lube, STP or similar mixed in for the tappets

Hi Sol, as you named the thread OILS AINT OILS you will know who SOL was !  Probably everyone on the forum runs different oils so I'm not going to suggest any particular oil but just let you know what oils I use. I use Penrite HPR 30 in the front forks, engine and primary drive and 80/90 gear oil in the gearbox. I have been using these oils for nearly 30 years and thousands of miles in different bikes without a problem. I change the engine oil every 1,000 miles. I sent you my e-mail address so feel free to contact me if I can help with anything.      Brian.
