These are artificially made using chemical compounds, which is a contrast to conventional motor oil made from refined crude oil. There are two types of synthetics:
Full synthetic oil
This oil is blended using different types of additives to provide the best engine protection and for improved vehicle’s performance. These oils use the best-performance additives and fluids. While all they are not equal, its brand and density don’t matter much.
This type is also called synthetic blends which are a mix of mineral and not more than 30|% synthetic oil. It’s better than conventional oils and much more advantageous than full synthetic oils without the expense.
When your engine grows old
The engine tends to grow weaker as it grows old and doesn’t respond well to normal wear and tear. This is when it’s important that you regularly change oil otherwise the trapped contaminants will end up damaging motor parts. It’s only with regular oil changes that the aged parts are properly lubricated to prevent any possible premature motor failure.
Recommended synthetic oils for older cars
Full synthetic oils are always a good choice for older vehicles that have been used a lot. They are perfect for lubricating motor parts as they do it much better than any other oil. And in the process they helped increase your car’s fuel economy, reduce the emissions and in the process help increase the automotives lifespan.
The only problem with using it for your car is that these oils are thinner than conventional types. So this can lead to the oil bleeding more with time. This problem can however be rectified if you use a full synthetic oil that has a higher viscosity.
It is worth switching to high mileage oil if your car has been fun for more than 75,000 miles. The benefit and reason for using this oil are because it contains many additives which can help seal, and stop possible leakage. It also helps reduce friction in the engine and holds an important role in reducing the amount of sludge deposited. And in the long process it protects your motor so that it works better.
Benefits of using synthetic oils in older vehicles
You can reap the benefits of this type in older vehicles as long as your vehicle is in good running condition and has minimal leaks. Some people are hesitant about using these oils because they think that it may only trigger some problems. The main reason for this confusion is because the benefits of synthetic oil has a lower viscosity than conventional motor oil, and is more slippery oil. Some also worry that the oil may not be compatible with seals and can leak in some places while conventional may not.
However all this is a misconception because this oil does protect the engine in aged vehicles as well as they do the newer models. Besides, most synthetic motor oils are more compatible thanks to its modern seal materials. And as most synthetics are formulated to condition seals they can be adjusted to prevent leaks.
Benefits of switching to synthetic oils
There is no particular formula or procedure for making the switch. However, as a precautionary measure, it’s better to first do an engine flush so that it is clean and free of any accumulated contaminants which eventually affect the synthetic motor oil’s life. However, this is not a steadfast rule and it’s rather easy switching to using synthetic oils in all automotivies.
Some people worry about making a switch to using full synthetic oil because they fear it can lead to the cleaning and loosening of sludge from the motor. And if all this isn’t removed it can end up plugging the oil filter and passageways. This is also false because there will not be any clogging of oil filter or passageways when you switch to using a modern oil from a conventional motor oil.
It is true older cars have a tendency to form engine sludge and their oil seals and gaskets aren’t as tight as newer cars. This works as a sealing mechanism so when a synthetic oil is used, its advanced detergent additive cleans it out. So there’s a chance of some of the debris which worked as a seal of getting removed. And this can lead to an oil leak.
However, this doesn’t imply you shouldn’t change from using a conventional to a modern oil in your old car. You just have to note your car’s oil usage after making the switch and perhaps change your oil and filter at the same time.
And if you want some suggestions for synthetic oils to use in your old car, then some options are Castrol synthetic motor oil, Pennzoil 55004233-6PK Platinum Euro L Full Synthetic Silver 5W-30 Motor Oil Lubricant, Royal Purple ROY11748HMX SAE 5W-30 High-Mileage Synthetic Motor Oil and the Polaris 2877883 OEM VES are some of the top selling types of motor oil available in the market today.
You have to make your choice based on your budget, the respective pros, cons and features of the different oils to find and start using the best suited oil for older cars.
Synthetic oil vs. Conventional oil older cars
Cars that are referred to as older cars are vehicles manufactured before 1990 or so. This means that the gaskets, seals and other parts will not be as tight as the new models. However Regular maintenance of the car engine, with a regular oil change, can go a long way in extending its strength and performance.
Failure to do so will lead to all the contaminants in the oil damaging motor parts. Regular oil changes lubricate aging parts to help save any potential premature failure. The question arises as to whether you should use synthetic or base oils in aged cars because of the mixed opinions and feedback you get for the two. So here’s a comparative article between the two worth reading.
Advantages of synthetic oils
- As mentioned earlier, it’s a common myth that synthetic oils are not safe for older cars mainly because it’s slipperier or lower in viscosity when compared to conventional. It’s also thought that this type is not compatible with seals, and can lead to leakages in places where base oil wouldn’t have triggered leaks. This is all untrue because they will in the long run, help enhance and protect old engines just as they do new cars. There was a higher chance of this occurring in the past because mostd them contained esters, organic compounds mixed with alcohol. It was this combination that was hard on seals, and lead to potential leakage.
- However there have been improvements in modern oil technology over the years and while it’s true that old car seals may not be able to handle the additives in the oils, it’s possible to make the switch if it’s done gradually and pre-planned.
- In fact, it’s better to use synthetics because they clean all the contaminants and sludge formed during the combustion process like soot, sulphuric and nitric acid and carbon generated by the motor. This leaves a clean and protected engine that boasts of a high quality performance and works much better than dirty old and new motors.
- As they take a longer time to break down they easily withstand high temperatures and flow easier in cold temperatures. This increased stability in cold temperature makes the oil best for cars in very cold winter regions or very hot summer regions.
- When it comes to this type of oil, 80% is usually the oil’s base oil while the remaining 20% constitute additives. The synthetic base oil has chemically engineered molecules with uniform properties. This leads to cleaner oil.
- Regular use of modern oils in older engines leads to cleaner pistons, improved fuel economy and horsepower protection, extreme temperature performance and optimal wear protection.
- As synthetics are thinner than conventional motor oil, the engine may bleed if there’s a leak. There is also the chance of them leaving leaks while cleaning out debris, which in turn leads to the car burning oil. The solution here would be to look around and to use higher viscosity oil. You will also have to monitor oil levels and replace it as required otherwise parts may get damaged.
- Synthetic oil being expensive is another disadvantage. However not many realize that they actually end up saving money in the long run. They work and last for a longer time in engines, which means you require fewer oil changes. However just because it’s long-lasting doesn’t mean you can be careless when you change your oil. You need to maintain a regular schedule for changing oils.
For Those who like Conventional Oils
Advantages of conventional oils
- One of the main reasons to still use base oils in older cars is that it’s a more cost-effective option. Most synthetic oils cost twice as much as conventional, even amongst the same brand. This is why some people don’t consider it’s worth using such expensive oil in cars that don’t particularly require it.
- Modern oils in old cars that have run more than 75,000 miles tend to flow much more smoothly than conventional types, which can lead to a greater chance of grinding gears in the engines. This is why many manufacturers recommend using base oil because they offer better lubrication for the old motors. This leads to your car lasting for a longer period, much longer before it’s meant to go.
Disadvantages of conventional oils
- However base oil molecules differ in shape and impurity levels. They also tend to break down quickly which is why this type cannot perform well in extreme temperatures nor flow easily in cold temperatures.
- Conventional oils are not advisable if you have to make frequent short trips because the oil may not get hot enough to burn any moisture and impurities found in the oil. This in turn leads to base oils breaking down at a quicker pace.
What should we know before switching conventional oil to synthetic motor oil?
Synthetic oil is lab-created oil with a base for lubrication of engine parts, performance additives and carrier oil for additive suspension within the mix. The additives come in powder form. It is however more advantageous to its molecular stability with changes in temperature and prolonged maintenance that it provides in the oil-change intervals.
Owing to its advantages, vehicle owners prefer switching their conventional oil to synthetic oils for better performance and maintenance. However, before switching from conventional oil to synthetic motor oil we have to clear some myths and have a clear understanding of why and how the switch should be done.
Is it safe to switch from conventional to synthetic motor oil?
Yes, it is very safe to make the switch to synthetic motor oil from conventional oil.
Can switching to synthetic oil cause leaks?
It is the most common myth that synthetic oil may wear the seals protecting the engine and result in leaks, which is not true. However this myth arose because of the manufacture of synthetic oils. Synthetics are created from esters that can be tough on seals.
Neoprene an ester, is specifically hard on seals. They would shrink the seal. But the current manufacture of synthetic oils is delicate on these engine seals. Synthetic oil will not leak, but if there are any leaks it will help you find one.
These oils clean engine deposits. If there is a cracked seal, its streamlined structure flows through the crack. These oils clean the sludge deposit on the seal and reveal the cracks within a seal. Thus, the cracks are revealed.
When should I change my car to synthetic oil?
The ideal time to switch your new car to synthetic oil is post the preliminary oil change. Lubrication is very good with synthetic oils and so the new engine doesn’t break-in. Synthetic oils are very slippery and so the wear factor is minimal.
The initial oil fill will help a little wear and tear of the new ring, after which the ring-wear is sufficient for the engine to break in. This is when the switch to synthetic oil has to be done to get the maximum advantage of the oil change.
When should the switch from conventional to synthetic oil be done?
The oil change intervals differ from one manufacturer to another. Even though the manufacturer of the vehicle recommends the oil change there’s a rule of thumb that is followed for the switch. Conventional motor oil should be changed every 3k-5k miles. For a synthetic oil change an interval of 7,500 miles is recommended in between.
A longer interval is considered for the change as synthetic oils tend to have lesser impurities and best on the engine compared to conventional motor oil. Therefore, synthetic oil can go longer than conventional oils.
If you wish to switch your vehicle from conventional oil to synthetic oil it is best to do after the preliminary oil fill. When you change your oil for the first time this is the best time to make the switch, as mentioned above.
Is synthetic oil better than conventional?
We know that synthetic oils are man-made. The primary difference between conventional and synthetic motor oil is their molecular structure and a stable framework. Conventional oils have natural elements that tend to stay inconsistent with changes in temperature. Synthetic oils give stable and good shields to your engine.
When compared to conventional motor oils, synthetic oils are better and more performance-oriented in the vehicle. The viscosity index of synthetic oils is high. The oil offers great resistance to weather changes. This implies that neither heat nor cold environment impacts the oil very much, which gives a good capability to shield the engine
Below are listed some benefits of synthetic oils:
- Molecular size is uniform resulting in lesser friction in the vehicle.
- Performance-oriented additives that enhance engine protection and engine cleaning.
- Engineering and refinement to minimize deposits.
- Lesser impurities and cleaner oil.
- Better operation in extreme weather and cold conditions.
Synthetic oil versus conventional oil advantages
- Lesser emissions.
- Better oil and fuel economy.
- Longer oil change intervals without compromise on performance.
- Enhanced protection of the engine.
- Enhanced wear protection due to lesser friction.
- Higher resistance to oil thickening and so minimized engine drag.
- Uniform oil quality and efficiency.
- All-weather engine shields.
- A faster start time of engines.
- Cleans oil deposits and sludge within the engine.
The real advantage of traditional oil versus synthetic oil
- Cost efficiency due to additional protection to the engine.
- Good gas mileage.
- Synthetic oils are six to ten times the traditional oil costs.
- Synthetic oil switch from conventional oil can clear leakage plugging by cleaning deposits on them. Clogged leaks are dangerous.
- Switching to other oils from synthetic oil is not an issue.
- Synthetic oil additives are beneficial.
Can you go back to conventional oil after using synthetic?
It’s a myth that one cannot switch back to conventional oil once you start using synthetic oil for your vehicle. This is not true and yes, you can go back to conventional oil use. Synthetic oils are a blend of conventional and synthetic components.
There is nothing special to do when switching from synthetic back to conventional oil. This is because the oil blends well with conventional oil of the same weight without any engine flush. They are compatible and not so harmful to the engine or the vehicle in any way.
How do I change from conventional to synthetic oil?
If you are doing the switch for the first time, then there are two ways:
- Get synthetic oil. Dust the drain pan off and pour the synthetic oil in. This will not result in any issues.
- An engine flush can be done before the change. It is not mandatory. The benefit is that it eliminates the debris and sludge that is accumulated within before the oil change. The rate of build-up will reduce.
Conclusion on what synthetic oil is better for older cars
There is no steadfast rule about which is better oil for your old automotive. It all depends on your car, its usage, where you live and the environmental conditions. While synthetic oils were once difficult to access, you can easily buy both types online today.
Switching to Synthetic oil from Conventional oil is the right choice owing to the benefits that the switch offers, as mentioned above. The switch can be done either directly or after an engine flush. The switch is worth it and involves no harm to the engine or the vehicle.
To be on the safer side it’s always better to make the switch after talking to your professional technician and to make a gradual switch. This protects your car and ensures it performs for a longer time.
