I've been using Johnsen's 4624 high viscosity oil treatment for a couple of weeks now, and I really notice the difference in my engine's performance. It runs smoother, and I feel more confident about its longevity. This 12 oz bottle is just the right size for my DIY oil changes!

Engine runs quieter now
Johnsen's high viscosity oil treatment is a solid addition to my routine. My engine is noticeably quieter after using it, and I appreciate the 12 oz size for easy handling. Just wish I knew about this sooner!

Good product but shipping took forever
The Johnsen's oil treatment seems to be working well in my truck. I've noticed less engine noise and smoother operation. However, it took over a week to arrive, which was frustrating. Just wish the shipping was faster next time!

Helps with my older car's issues
My 2001 sedan was showing signs of wear, so I decided to try this high viscosity oil treatment. It definitely helped with oil leaks and seems to make the engine run better. It's worth trying if you have an older vehicle!

Disappointed, bottle arrived damaged
I was excited to try this oil treatment, but the bottle arrived dented and some of the product leaked out. I haven’t used it yet since I'm not sure how much is left in there. Quality control needs to be better for the shipping!
