Best RC Vehicle Oil & Lubricants of 2026

"I use this in my RC crawler shocks and it really performs well. Plus, it arrived quickly, which I appreciate."

"As a newcomer to RC shock oils, I chose Losi since it's a well-known brand. The oil has worked great in every set of shocks I've tried it in—no issues at all."

"Although I purchased this silicone oil for my art projects rather than for shocks, it still works excellently for my needs."

"I've tried this shock oil on my 450g RC car and just a few drops in my Injora 40mm shocks make a noticeable difference. The silicone base keeps O-rings in good condition, and the price is unbeatable at only six bucks. Great value for basic tuning and maintenance."

"Since replacing the old oil in my 1:18 RC truck with this Losi shock oil, my truck now handles bumps and jumps way better. The quality matches what you'd expect from the Losi brand. This is now my go-to shock oil for all my RC vehicles."

"It works exactly as it should in all my RC car shocks. Super reliable, though application can get a little messy."

"I've found that TLR shock oil consistently delivers excellent results for my RC bashers. The value is great, and this has become my go-to brand. I'll definitely be getting more!"

"In my experience, Team Losi's shock oils always perform reliably, no matter the weight I use. My only minor gripe is the cost feels a bit high for the 2 oz. volume."

"This oil works perfectly for my Traxxas shocks and crawler builds. It's also a solid choice for low center of gravity rigs. Packaging and delivery were both great."

"I've found this oil to be a cost-effective option from a brand I trust, Losi. It does exactly what I need, so I plan to stick with it."

"The oil is easy to handle and the bottle’s secondary seal is a big plus, making storage between uses much simpler. I’m definitely interested in trying other oils from this company."

"The leak-proof design and secure cap are excellent—no mess in the package. It’s worked great in my Arrma Typhon 3S and Losi Tenacity, especially when using ZD Racing shocks for big jumps on the track."

"I use these lubricants for my speed Rubik’s cubes, especially larger ones like 5x5 and up. The 10k oil is perfect for inner tracks, making my cubes smoother without slowing them down too much. The price is totally worth it for the quality you get."

"I'm happy with the assortment of lighter diff fluids in this set. The squeeze bottles with dispenser caps make it easy to fill my diffs, and I think the price is reasonable for the selection and size."

"While the product didn't fit my specific purpose, I found the bundle cheaper than buying individually and the packaging was solid. The only thing is the bottles seemed only half-full, and the foil seal was a bit hard to remove. Still, if you need different lubricant weights, it's a good deal and does the job well."

"I use this RC shock oil in my GTRs and it performs phenomenally on my Traxxas VXL Hoss. The handling improvement is definitely noticeable."

"The bottle is a good size for the price—I filled about eight shock absorbers and still have plenty left. Really good value!"

"I experimented with different oil weights for my 1/10 short course trucks and found this one to be just right at 516cst. Even after a lot of use, I still have about two-thirds of the bottle remaining."

"I've had excellent results using this in my rear diff, paired with heavier weight in the front and a 1 million center. With some tuning, all four wheels are almost always on the ground. I'll keep experimenting with different weights, but it's definitely quality fluid for dialling in my basher."

"I rely on this brand for all my RC cars, especially for moderate to heavy bashing. Works great in the rear differential of both my cars and trucks. Plus, shipping was impressively fast, arriving even earlier than expected."

"I actually bought this oil for an unusual purpose—servicing the viscous fan clutch on my Montero Sport. The fluid’s thick consistency is perfect for high-heat environments like the Desert Southwest. If your fan clutch is serviceable, this is the best solution I’ve found."

"I've relied on this oil for my RC cars for years. It’s always dependable, fits easily in my toolbox, and never leaks. The smaller bottle makes storage simple and it’s a great deal for the price."

"I use this oil with my CR12, and it’s fantastic for RC shocks. Just make sure to get the right weight oil for your rig. The only trouble is the dispenser—it’s messy, so I recommend buying an eyedropper."

"This oil has made my RC rock crawler much more stable and less bouncy. For the money, it’s easily the best upgrade I’ve made to my truck."

"I noticed a significant improvement in shock performance after using this silicone oil in my WLtoys WL144001. The bottle is a good size and the price point is very reasonable. I do wish the cap had a nozzle, but overall it's pretty easy to use."

"While I've received the wrong weight oil a few times when ordering 27.5 wt, every other experience with Liquid R/C has been excellent. Their products are always as described, and customer service is reliable. Just be cautious if you need 27.5 wt shock oil, as there seems to be a mix-up. Otherwise, I highly recommend them."

"I've always had confidence in Losi products and this grease really delivers. It offers excellent performance for RC cars and stands out for its value compared to other brands."

"After using this in my TRX4M transmission with metal gears, I noticed it distributes smoothly and evenly. I haven't tried alternatives but I'm planning to stick with this grease."

"The compact tube makes it easy to keep in my toolbox, and I'm happy with how well it works on my gears. Plus, it arrived exactly as described, which I appreciate."
