THIS RIGHT HERE!

I have read dozens of oil threads on car and bike forums over the years. And my take-away is that in most non-specialized applications, most modern oils are just fine for our dinosaurs who, by the way, fared pretty well with the far inferior oils (by today's standards) available during most of their lives. Which is why there is always LOTS of positive recommendations for a myriad of different oils. It's because ALL of the major oils work just fine for the typical, non specialized application.

Personally, I use YamahaLube. Not because I think it is the best. But because it is not expensive, is readily available, and has never caused any kind of issue. I run it in my Enduro and my RD and have run it in all my Yamahas forever (meaning decades). How much better than that can you get by spending more money or going to more difficulties in acquiring your oil?

I want to change the outer crank seals on my '74 RD350. What source for the seals do you recommend?

Thank you.

As far as wanting the most economical solution I find nothing beats Rust911 in the 1 gallon concentrated jug. It makes 16 gallons and at that dilution level it is as effective as Evaporust. At $80 for the gallon that breaks down to around $5 a gallon. For me it works to have plenty of solution in shop and not have to continually buy single gallon jugs of other brands.
 I think I shared this earlier in another thread.
