Review: WORKS WELL!!! Nothing better out there!! - This stuff is amazing!!! Simply incredible what it has done for the truck! Used it in a 07 Honda Ridgeline that’s had a power steering issue for well over 5 years. Having tried multiple different brands of power steering whatever products and nothing fixing the issue or even alleviating it a lil…I came to the conclusion that it needed a new pump or a complete system overhaul…see I never saw a leak but I couldn’t get my boy to take it to a shop..I know but he just wouldn’t anywho…I had found Liqui Moly and their Insanely Crazy Bad A** products and used a couple other products in my car and was surprised at how well they had worked so I when I saw this read some reviews and thought who knows maybe it help a bit…this because when you’d drive it , it was like driving a manual steering instead of one that had power steering. If you’ve ever driven a vehicle without power steering you’ll understand. It’s almost impossible to park or back out and forget parallel parking! So I figured it might help a bit but nothing like it did….i put it in the truck and WOW….simply…WOW….now it was about 75 to 100 miles before I noticed it but what a difference….its almost like a new power steering system completely!! My boy was thrilled!! And was a bit shocked I’d say….Tbh idky I’m so surprised …it seems like all Liqui Moly products are like this…beyond top shelf…better quality than anything on the market…no matter what product it is they are the best!! This is one company that has nothing but superb quality products!!!

I used this in my bushog gear box that was leaking at the output shaft seal. It is a real PITA to change that seal, so I gave this a try. The leak has reduced a significant enough amount that I can wait till a more opportune time to change it, as it will take hours of work. And it’s too hot to do it now!
