How effective is PlanetSafe OT at lubricating?

Results from the industry standard ASTM D-4172 Four Ball Wear and Coefficient of Friction Test demonstrate the lubricating effectiveness of PlanetSafe’s active ingredients. The Four Ball Wear test spins four ball bearings under constant pressure and heat with the test lubricant. The coefficient of friction is measured during the 60 minute run and the average wear scar is determined. Results show that treating off-the-shelf oil with PlanetSafe OT reduces the wear scar by 23% That translates directly into longer life for tools, equipment, and weapons.

Makes my car run like new

I use this on my car that has almost 300,000 miles. When I use it the car gets the same mileage it got when brand new. Engine runs smoother like it’s hardly under a load.

Seems to work

I had a bit of valve train noise on start up and I can say that it is gone since using this product.

Reduces friction

Have replaced a few major parts on my 2003 Ford F150 and thought I'd use this as a preventative maintenance.


Didn’t work

OT Treatment

Good stuff. Seems to have cured the cam phaser knock in my '09 f150. Only disappointment was I ordered two 8 ounce bottles, but only received one.

Hi Devon H,

We are pleased to hear that our product was successful in solving your issue.
Thank you for your 5-star review, considering our mistake in your order. We are happy to rectify the matter...Your second 8 oz bottle has been shipped. Sorry for the mistake on our part.

Results show that treating off-the-shelf oil with PlanetSafe OT reduces the wear scar by 23%

Enhances lubricity and reduces friction – demonstrated with independent lab tests using the industry standard 4-Ball Wear Test and Coefficient of Friction Graph (ASTM D-4172 – 40 Kg. 1200 rpm, 1 hour at 75 degrees C). Results show that when PlanetSafe-OT is added to standard SAE 10W-30 oil there is less friction than standard 10W-30 oil and synthetic 10W-30 oil for the critical first 25 minutes. Because most engine wear occurs at start-up this period is crucial to reducing engine wear. Wear scar measurements after sixty minutes of testing show that PlanetSafe-OT reduces wear when compared to standard SAE 10W-30 oil and synthetic 10W-30 oil without the additive.
