how do I use lucas oil stop leak?

When you change your oil put the stop leak Quart in in place of 1 of the Quarts of oil,then drive regular till next oil change.Unless your leak is extreme Lucas will stop the leak. I've used all the Lucas products for years in my cars and my 18 wheeler before i retired. Now i still use it in my personal vehicles. Love that Lucas!

2 questions: Does this need to be added every oil change like other products? Is it really thick like Motor Honey? Thanks!!

If your leak stopped then discontinue use, if you still have a leak such as from your main seal then you'll keep using this every oil change until either you die or your car does first. It fixes small and small medium leaks. If it's medium it helps but you'll need it every oil change and large leaks it won't fix. My rear main seal is leaking and instead of removing the engine to fix it I will be using this on every oil change forever. Best of luck!

Can you use this on a Mercedes CLK320, 2004, and not hurt the engine?

The label says All engines. I have used it in a BMW 4.4 with no signs of any problems. Just don't exceed the 20% ratio of stopleak to oil.

Can i use both this and the lucas oil stabilizer at the same time?

I pulled this info from the vendor.Use Lucas Oil Stabilizer in gear oil to stop leaks, reduce operating temperatures and increase the life of the gear oil. Since it is pure petroleum, it can safely blend with all other automotive lubricants, even synthetics, ATF and mineral oil. It keeps old engines alive and new engines new.
