Quite impressive products!

1978 MB 300CD
“… increase in engine performance is quite significant…”
MB 300CD oil
“… typically the engine oil is black immediately after an oil change…”

“I wanted to take the opportunity to say how much of an improvement I have seen since using your products. My 1978 Mercedes 300CD currently has in excess of 342,000 miles. I have owned this car for over 37 of its 45 year history. So naturally, I know when it’s running well, and when it isn’t. The reduction of exhaust particulate and increase in engine performance is quite significant. I use Liqui-Moly engine oil with Mos2 which has a grayish appearance, otherwise I believe the dipstick would have been perfectly clear after performing the flush. Typically the engine oil is black immediately after an oil change. Thanks again for producing some quite impressive products!“
