Lucas oil treatment

I know that you use and recommend Lucas oil treatments but I've read lately that it can be bad for engines. I wonder what is your opinion about it.
Experienced mechanics share their insights in answering this question :
I use it, yes. But I use it on the older, worn-out engines and it helps build up the compression because it is a thicker oil and I believe it has molybdenum sulfate, which is a very good metal cleaner that clings on to metal. But I wouldn’t use it on a modern new engine that doesn’t have any problems because those modern cars are made for the 0W10 oil, which is super light. You don’t want to use them on a car that uses very light-weight oil.

When added to fuel, it cleans and lubricates all components from the fuel tank to the cylinders. When added to your oil, Lucas Complete Engine Treatment cleans your engine and forms a protective barrier against heat and friction, improves oil flow in cold weather and extends oil life.
According to Lucas, the oil stabilizer will not only prolong the life of an engine, but it will also provide you with approximately 50% more time between oil changes.
A: We recommend adding a bottle of Lucas Transmission Fix each time you change your transmission fluid (approximately every 30-40,000 miles), or adding a bottle to your current fluid to fix a small leak.
Without additives, the oil is essentially unable to perform its critical functions. Wear, oxidation, and decomposition can cause the oil to degrade over time. Engine oil can lose its additives the older the oil gets.
In doing so, Lucas Fuel Stabilizer effectively preserves your fuel for up to 12 months or longer.
Lucas Pure Synthetic Oil Stabilizer reduces friction for more power and more MPG. It eliminates dry starts in new engines and provides the extra protection needed for import and domestic engines requiring newer, lighter engine oils.
Directions For Use

Deep clean as needed, at least every 3 to 4 thousand miles. 16oz Bottle – For a Deep Clean, pour entire bottle into fuel tank and fill with any grade gasoline, up to 30 gallons. Deep clean as needed, at least every 3 to 4 thousand miles.

Allow a few days for Lucas Engine Oil Stop Leak to correct this problem. To keep this problem corrected a quart (or liter) will probably have to be added with each oil change. Use 20% of system capacity (example: 1 quart of Lucas Engine Oil Stop Leak to 4 quarts of motor oil.)
Oil additives can effectively reduce wear and stress on your engine to boost its long-term performance. Lubricants like antifoamants and anti-wear oil additives coat engine parts to prevent stiffness and seizure.
Since Lucas Heavy Duty Oil Stabilizer is 100% petroleum, it can safely blend with all other automotive lubricants including automatic transmission fluid, mineral oil, petroleum oils, and synthetic oils. As an added benefit, it can be used with every oil change and safely extends oil life 50% longer.
The recommended dosage is 2-3 ounces of Fuel Treatment for every 10 gallons of gasoline or diesel fuel. Pour Lucas Fuel Treatment directly into fuel tank. Exceeding the recommended dosage is not harmful to your vehicle.
It`s best to do a hot oil hair treatment every week or every two weeks, depending on your preference. Hot oil treatments will help deposit oil back into your hair and prevent the dryness that can contribute to breakage. Adding a DIY hot oil treatment to your weekly routine can also help repair damaged hair.
This reduces metal-to-metal contact and friction — a major contributor to heat, wear, and premature aging of engine parts. STP® Oil Treatment fights this metal-to-metal friction by providing a thicker cushion of oil between moving engine parts, thus helping to protect against engine wear.
In engines use approximately 20% or one quart to each gallon of any plain motor oil, petroleum or synthetic. In badly worn engines, use more up to 60% or 80% if necessary. In manual transmissions and transfer cases use 25% to 50%. In differentials use 25% to 50%.
Lucas Fuel Treatment should definitely be used in vehicles that require leaded fuel because it actually replaces the benefits of lead in gasoline without causing harmful emissions. Use it to pass smog tests. Finally, it totally neutralizes the harmful effects of low sulfur diesel fuel.
Lucas Oil has its plants in the United States. The original plant in Corona, California, which also housed Lucas Oil Corporate Headquarters and several affiliated companies, was closed in late 2022, moving the corporate HQ to Indianapolis, Indiana. Lucas Oil Products, Inc.
Simply put, the shelf life of conventional motor or “lube” oil is up to five years. It`s not something that goes bad in a couple of months. It`s impossible to predict exactly how long motor oil shelf life is because petroleum stability (how well it resists change in its properties) is situation-dependent.
Motor oils are graded based on their viscosity. 5w 20 and 5w 30 engine oils are commonly used in colder temperatures. However, they are recommended for older engines and light-duty use. This is because an oil with a higher rating indicates that it is thicker and suits well those engines which run hot easily.
You can easily add too much of a high-quality diesel fuel additive. What happens when you over-treat your diesel fuel? Overdosing can lead to a whole new list of fuel and engine issues from clogged filters to overall decreased engine performance and efficiency. If you`re losing lubricity, don`t over-treat.
Lucas Oil Deep Clean Fuel System Cleaner is a powerful fuel additive designed to clean the entire fuel system from the gasoline tank, to the fuel pump and fuel injectors. In addition, it removes carbon deposits on intake valves and combustion chambers, including piston tops.
You can use it as many times as you want. At every fill up if you wish.
Directions For Use

Deep clean as needed, at least every 3 to 4 thousand miles. 16oz Bottle – For a Deep Clean, pour entire bottle into fuel tank and fill with any grade gasoline, up to 30 gallons. Deep clean as needed, at least every 3 to 4 thousand miles.

Oiling your hair 1-2 times a week is enough. Doing it everyday can attract dirt and also strip away essential oils from your hair. Combing, rubbing and vigorously massaging your hair with oil can also cause breakage. So, follow the steps we mentioned and healthy, beautiful hair will follow.

lost all oil pressure, replaced the oil pump, low oil sensor, oil pressure sensor, oil pan gasket,
ANSWER : The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.

Oil consumption. Burning oil. Oil light turns up on idle.
ANSWER : Hi there, thanks for writing in. The valve stem seals are the most common cause of this on your engine. When they fail, it requires that the cylinder heads be removed and rebuilt to fix it. The piston rings can also cause this but they are not as common. Unfortunately there is not anything, not even heavier oil that will fix this. You will need to have the heads rebuilt.

Oil still leaking after I changed oil filter
ANSWER : Unless there is an imperfection (e.g., serious pitting or irregularities) on the engine mounting base for the filter gasket, the leak is probably not at the filter. There are other adjacent potential leak spots such as the oil pan gasket, oil pressure sending unit and so forth. If the leak is significant at all, merely thoroughly cleaning the suspect area and running the engine while looking for the leak should be sufficient. If you still can’t find the leak origin, a UV visible dye can be added to the engine oil which will then make the leak point visible using a detection light. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an oil leak diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

2006 BMW oil filter gasket keeps breaking and oil leaks from oil filter. Oil leaks only after starting car in morning. PCV valve?
ANSWER : Hi There,
It sounds like you may need to replace the oil cap o-ring. If you haven’t done this before there are two O-rings to replace; a small green one on the base of the filter cap stem and the large black one that seals the filter cap (which seems to be the one you are having issues with). The large O-ring sits in a small square-shaped groove that is at the base of the oil filter cap. It is very easy to not properly seat the large O-ring because the threads for the oil cap are quite large and will accept the O-ring if you are not careful. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.

My car is leaking oil i got an oil change for it last month but it is still leaking oil what will cause my car to leak oil ?
ANSWER : Most older cars have oil leaks. Sealing technology has just not kept up with mechanical improvements to engines so much so that leaks often kill engines rather than mechanical problems. So, it is not unexpected at all to have an, indeed many, oil leaks on a 23 year old car. Oil leaks vary hugely in terms of severity and priority of repair. Oil leaking onto a hot engine manifold is the worst case (the oil can start a fire; at best, you are left breathing oil fumes in the cabin, as the oil burns off of the manifold) while de minimus seepage of oil at the oil drain plug or oil pan gasket, while annoying and messy, if limited enough is not an emergency. Some leaks are easy to repair, while others literally require the engine to be removed just to get physical access to all the leak points. In your circumstance, if you smell burning oil, oil is probably leaking onto a hot engine part such as the exhaust manifold. A certified Mechanic, dispatched by YourMechanic right to your location, can perform an oil leak diagnostic and then let you know of your repair options and costs.

As far as the check engine light, that is not related to the oil leak(s). If you request a check engine light diagnostic, a certified mechanic from YourMechanic would use a code scanner to retrieve the specific diagnostic trouble code(s) from your car’s PCM that have caused the check engine light to illuminate. Using those codes, the appropriate individual vehicle components or sub-systems (often a sensor, circuit, and the like) are then carefully tested, based on specifications set forth in your car’s Factory Service Manual, to pinpoint the cause of the fault or the reason why the check engine light has illuminated. Once the faulty part or component is identified, it is explained to your satisfaction and the mechanic will let you know of the cost to repair. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Just noticed a huge oil leak trailing my car. It seems to be coming from below the engine. I recently had my oil changed a month
ANSWER : You might have a problem with the oil filter leaking when you rev the engine and increase the oil pressure. This can be from a collapsed oil filter media or excessive oil pressure from the engine. I recommend having the oil and filter replaced using a good quality filter and have the oil leak verified to be from the filter. Make sure to not run the engine low on oil. If you are finding you do not want to drive with the leak, a mobile technician from YourMechanic can come to your home or office, and replace both your filter, and oil.

Stop car check oil warning
ANSWER : This light will usually come on when one of two things are happening. Either the motor is in fact low on oil or the oil pressure sending unit is not working properly and may be producing a faulty reading. I would recommend first, to check the actual oil level in the motor by using the dipstick. Be sure the oil level reaches the "full" mark. If this registers as "full" then you likely have a faulty oil pressure sending unit. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your low oil pressure light to come on.
