My first time using Cilifer and I can tell the difference. My engine feels better and it runs smoother and quieter.
I run this in several of my vehicles, and every vehicle is noticeably smoother and quieter. I also use it as an assembly lubricant and it works very well.
I got it for my father, sister and my lady. They noticed the difference and were impressed. Their cars are running much smoother after using Cilifer® LubriBoost.
Added this to my 2018 truck during the last oil change. Engine noise dropped almost immediately and throttle response feels crisp.
My old Suburban was starting to rattle on cold starts. Poured one bottle in and the lifter tick disappeared within 50 miles.
Mechanic suggested giving this a try. Very satisfied with how much quieter the car runs now, especially in cold weather.
Over 180k miles on my daily driver. Engine runs like it has half the mileage after adding LubriBoost. Highly recommend!
The vibration at stoplights is completely gone. I was skeptical at first, but this stuff genuinely delivers results.
Used in both my personal car and work fleet. Consistent performance improvement across all vehicles.
Just add it in with your fresh oil change. Super quick process and the engine sounds noticeably healthier.
Noticed about a 1.5 MPG increase on highway trips since adding this. Engine friction reduction seems legit.
Will be buying a bottle for every oil change moving forward. Quality product that does what it advertises.
After your first oil change, your oil may appear darker as deposits are lifted from the engine. With continued use, subsequent oil changes may stay cleaner for longer. Since every engine is different, many drivers may notice smoother and quieter engine operation.
For ongoing performance and protection, we recommend adding Cilifer® LubriBoost at every oil change.
The recommended treatment amount varies by application:
If your crankcase is already filled to its maximum capacity, drain enough oil first to make room for the treatment. Do not exceed your engine’s recommended oil capacity, as overfilling can cause damage. If the oil level is below the maximum mark on the dipstick, you can generally add the appropriate amount without draining oil first.
Yes. Cilifer® LubriBoost can be used with both conventional and synthetic motor oils
Yes, but compatibility should be confirmed in your motorcycle owner’s manual first, particularly if the manufacturer advises against friction modifiers. For compatible wet-clutch applications, use 1 oz of Cilifer® LubriBoost per quart of engine oil.
Generally, using an aftermarket oil additive does not automatically void a vehicle warranty. However, warranty coverage can depend on the vehicle manufacturer’s requirements and whether a product is specifically incompatible with the vehicle. Always follow your owner’s manual and retain records of maintenance and products used.
Yes. New engines typically require a manufacturer-specified break-in period. We recommend following the engine manufacturer’s break-in instructions before adding Cilifer® LubriBoost oil treatment.
