Owner reviews for oil additives

I just put a can in my old mustang engine and it’s never felt so tight and smooth. Definitely good for older engines!

I use it in my Cadillac. It’s got the 3.6 vvt with the 3 timing chains. The motors like to rattle on startup even when there’s nothing wrong with the motor. No correlation codes no misfires. When I add this it quiets down considerably.

i always use liqui moly and mann filters. my buddy had an extra can of this stuff in his garage and gave it to me. i put it in, oil consumption went to 0.

Anyone ever run this liquid moly oil additive did last night and can already feel the engine running smoother and quieter

What made the biggest difference was an oil additive. I usually regard those things as "snake oil," but this is a Liqui Moly product, so I decided to give it a go. It's called ViscoPlus for Oil. At one point, I only burned one quart in 1000 miles, a significant improvement over 1 in every 500 miles. The last go-round with Viscoplus it was somewhere around 750-800 miles before I had to add a quart. I highly recommend the Viscoplus.

I had a cheap Volvo S40 commuter with bad valve stem seals back in 2011. I was about to tear into the engine, when a trusted friend/parts manager/guru recommended I try a can of Liqui Moly Motor Oil Saver as a last ditch effort. Within a couple drives the symptoms were gone, and last I heard the car is still running strong today.

I'm using Castrol Edge (or whatever) full synthetic 5w40 + about 250mL of Lucas engine oil additive (that stuff has done amazing things for other high-mileage engines I've had in the past).

I swapped a motor into my golf yesterday fired it this motor hasn't ran in like 4 years. Right away the valves were clack a lacking like crazy even after running for 15 minutes and pumping up there was still one or two of them were quite loud. Added a half quart of mmo amazing no more noise.

That stp additive with casterol high mile age. Still have lifter noise but alot less. Runs smoother and quieter
