Does Lucas Oil Additive Really Work?-2024

Last Updated on September 13, 2022 by John Robinson

According to most testimonies, yes Lucas oil additive really work.

Lucas Oil Additive enhances the lubrication of your standard oil; it also adds chemicals that improve the oil’s viscosity. This means the oil is essentially ‘thicker’ and lasts longer, and protects your engine better. This will help keep your engine running well, prevent problems like early corrosion, and even help get an old engine to perform better.

The additive can also prevent rust, stop the engine from smoking and prevent oil leakage. Other additives include anti-foaming agents (which prevent unneeded corrosion) and detergents, which clean out any impurities in the engine.

Most older engines benefit from an additive, and engines that have seen some heavy wear and tear will also benefit from an additive.

Should I use Lucas Additive Oil?

On old engines, it’s undoubtedly a yes; on new engines, it’s debatable. But really, it depends on the engine, the type of oil you’re already using, and how long you’ve been using the oil.

Many dealers will tell you that your engine needs an additive for optimization. Still, in reality, the factory standard is usually already at excellent quality to protect your engine and has been optimized specifically for your engine. Also, all shelf-bought engine oil is already made up of 15-30% additives. Before buying an additive, check what oil you’re already using and if your engine does need the extra help.

Your factory oil should also be good for at least the first 3000 miles; after that, the oil could begin to break down, and you’ll need an oil change. Mixing an additive with your new oil is undoubtedly an excellent idea as it does help prevent some wear and tear.

When should I add an additive?

When should I add an additive?

You can add an additive with your first complete check-up one year after buying the car or with your first oil change.

If your car is already a few years old, adding an additive can be very beneficial, especially if the vehicle is having some problems. Smoke coming out of the engine, weird smells, or the engine light turning on indicate that an additive might be what the doctor ordered. Perhaps speak to an auto-mechanic to get some options for your oil.

Can Lucas oil damage your engine?

Can Lucas oil damage your engine?

In theory, yes.

You run the risk of damaging your engine if you add an additive that unnecessarily thickens your oil. Think about it like this; when you start an engine, the oil needs to lubricate critical parts of the machine. If the oil is too thick, it will take more time to reach essential elements. If those parts are not lubricated, it will cause wear and tear on your engine.

But if you’re worried about those cold starts, talk to your local auto-mechanic and let them advise you on what your engine needs during those colder months.

Can you use Lucas Oil Stabilizer with full synthetic oil?

Yes! Lucas Oil Stabilizer has been specifically designed to be mixed with any oil type. 

How much Lucas Oil Stabilizer should I use?

If your engine is new, a quart per gallon of plain motor oil, petroleum, or synthetic oil is usually enough. If you want to use a bit less, then 20% can also work fine. Although with manual transmissions, a quart is best.

If your engine is a little older or it’s seen some decent wear and tear, you’ll have to use more. 60% to 80% is usually recommended. This can be less if the engine is older but still in good condition, so instead, double-check with your mechanic before mixing in, lest you use too much and waste the Stabilizer.
