To Lucas Oil,

    I own a 1995 Olds Cutlass Supreme, 3.1 liter engine.   At 188,800 miles, both the intake manifold gasket and a head gasket leaked coolant.  I thought it was leaking out the rear of the engine onto the exhaust manifold and evaporating.  It turned out to be an internal leak.  I drove the car for several months, adding up to 9 gallons of antifreeze/water until I decided to take the engine apart.  When I removed the valve covers, there was foam and I found an emulsion of 5W-30 Quaker state oil, Lucas Oil Stabilizer, ethylene glycol antifreeze and water in the oil pan.
By all means, the engine should have blown (spun bearings, etc).  It didn't.  The engine continued to run smoothly, even when it overheated.   I have cleaned and rebuilt the engine and it continues to run very well.

I believe the engine did not blow as a direct result of the use of Lucas Oil Stabilizer with each oil change.   The gray, thick, paste like emulsion was very slippery and has not yet separated.

I believe that the Lucas Oil Stabilizer continued to lubricate all the internal engine parts, even though it was emulsified with the other components.   It has amazed the people I deal with at my auto parts store, as well as area automotive technicians whom I have met at the store.  Each technician has agreed with me that in theory, the engine should have been permanently damaged.  They have all seen the car since the engine has been rebuilt and believe that something continued to lubricate the engine during all that driving.  Again, I believe that it was the Lucas oil added to the regular oil that prevented the engine from blowing.

I take care of 6 cars and put in one quart of Lucas Oil Stabilizer at each oil change.   The engines run smoothly and quieter with the Lucas oil than with only all regular oil.   You can actually tell the difference in the running of the engine prior to the oil change and after the oil change with the Lucas oil additive.   I have convinced several relatives to add Lucas oil at each oil change and will continue to advise anyone I speak to about cars to use Lucas oil with each oil change.

In my opinion, the Lucas oil additive coats the parts very well, does not wash off the parts either with time or temperature and acts as an excellent lubricant as it is pumped throughout the engine.

I highly recommend to anyone reading this letter to use Lucas oil.  You will definitely see an improved performance in your car’s engine and its life.
