Will this product freeze if left in an engine that's just sitting in freezing weather for several weeks?

Why would it freeze? It’s an additive, it only replaces 20% of your oil.

It's ok for diesel semi truck,,,???

Yes this is ok for diesel trucks. Coupon Code is Available. Thank you for the question. FamilyGoKarts 320-695-2899

on the Lucas - what is the ratio of mixture per quart of oil?

Lucas recommend using 20% of total oil capacity so if you have a 5 quart total oil capacity you can add up to 1 full quart of Lucas and 4 quart of normal oil. Hope this helps

Will this work for a leakng timing cover gasket on 2010 Prius?

I mean honestly probably not but it should slow the leak. I put it in my truck every oil change there's still little puddles in driveway but not as bad as it used to be

Stops leaks like none other

I've used Lucas Oil products for years and swear by them. I just recently bought a 1997 Dodge Ram 2500 HD with a Cummins diesel and the mechanic I took it to for an inspection told me the engine had multiple leaks (didn't specify their severity). I just did my first oil change and substituted 2 quarts of oil for the Lucas Engine Stop leak and the engine is loving it. I will deep clean the engine and see if there's an improvement with the leaks. In future oil change I will substitute 1 quart of oil for this product as recommended by Lucas.
