It's that time of the year... For my friend Jack K. I am starting The Official 2021 Lubrication Thread.
What are you using and why, including filters. In the engine, I alternative.between Redline & Lucas full synthetic 20W50 and like them both. Its a good thing, because I have a lot of both.
I also have K&N oil filters, HD oil filters & Mobile 1. I have not got to try the new HD M8. I have no complaint an any, but that nut on the K&N sure is convenient for removal/installation.
I currently have Redline Shockproof in the tranny & for me, while others are good, it just provides the best shifting. The primary currently has HD Formula Plus, but will change to Redline Primary fluid at the next service.
I also have a K&N air filter in the stock box & am happy with its performance and washable design.
I use their spray on oil and its very convenient.
If there are any errors, I apologise in advance, but I can't edit my posts.
