I've found that part of owning an old bike is catching up with a lot of missed maintenance. In the case of my old Honda sport tourer, the fork seals started to seep from 30+ years of use. The oil that leaked out was pitch black and runny as water, so my guess is that it was the oil that Honda put in back in the 1980s.Honda recommends using Dexron 3 ATF for their forks. You can go down a real rabbit hole figuring out what the equivalent weight of it is, but depending on who you ask it will be anywhere between a 7.5 and low 20 weight oil. Not very specific.Most people who ride bikes like mine agree that a 10 weight oil is the default, and that heavier riders might want to try a 15 weight. I'm on the heavier side (200+ lbs.) and I didn't particularly care for how squishy the front end felt with the factory fluid so I decided to go with a 15 weight shock oil to increase damping a bit.What a difference. The front end no longer dives under braking, and the bike doesn't feel like a water bed when the weight transfers back and forth. The extra damping is maybe a bit juddery on washboard surfaces, but on every other road type it feels a ton better.Sure, I could've used ATF or something like an ISO32 or ISO46 hydraulic oil and been fine, but part of what I'm buying is peace of mind. I saw how gunked up the old oil was and how many sludgy deposits I had to scrub out of the fork tubes. For less than $20, I have an oil with good reviews that has a known weight. If I want to adjust the damping, I have a starting point that I can use to compare, and since the oil is clear, I can take a sample and tell at a glance if it's starting to get discolored. I'm very happy with this choice.

I recently purchased the 56901 15WT Standard Hydraulic Fork Oil, and it has been a game changer for me. If I could give this product a 6 out of 5, I would instantly. It has potentially saved me thousands of dollars.What I Liked:- I appreciated that this product helped resolve the popping noises coming from the jack stands on my fifth wheeler. The local repair shop told me that this indicated the tension seals were going out and that fixing it would cost upwards of $400 per jack. With six jacks on our trailer, this would have been a significant expense.- After some online research, I discovered that Lippert recommended this hydraulic fork oil as a solution.- Rather than spending a fortune on repairs, I purchased two bottles of this oil, and the problem completely stopped.- The product performed perfectly without any hassle. It was easy to use and did exactly what I needed it to do.What I Didn’t Like:- Honestly, there’s nothing I would change about this product. It met all my expectations and solved the problem effectively.My Final ThoughtsThe 56901 15WT Standard Hydraulic Fork Oil is a lifesaver. It solved the popping noise issue with my fifth wheeler jack stands, saving me potentially thousands of dollars in repairs. The oil was easy to use and did exactly what I needed it to do. I highly recommend this product to anyone facing similar issues. It’s an affordable and effective solution that delivers great results.

Everything about it was fine. Made a huge difference in the feeling of my 07’ Harley sportster.The only thing that I disliked was it came delivered and the bottle was leaking. I lost some fluid and had just enough to do the job. If I was short a few oz more that would have sucked even more then the soggy packaging

Great price,fast delivery. I used this our 5th wheel leveling system cause of having sticking valve/solenoids. Our system was having jacks leaking down, not operating as design. I flush out fluid and added these and the system styart to work as design. Will be using for this season and do one more flush. Highy recommend this fluid and add it to your hydraulic system (only need 1qt). This help in keeping the valve/soleniod moving freely (not sticking). Even go for the peace of mind.

I usually by small little bottles of shock oil. Realized I can use this. Will buy in a 30 wt as well. 15 is pretty thin but workable. Will use this for all my RC shocks.
