Can you use any oil in a 4-stroke engine?
This is one of our most frequently asked questions and the simple answer is yes, as long as it does not say energy conserving on the label. Because cars need the extra mileage there are additives in the oil that is there to reduce friction.
Unlike 2-stroke engine oils, 4-stroke ones do not burn with the fuel. Instead, they go around the engine. While circulating, the oil lubricates the moving engine parts, disperses heat, and eliminates impurities. Therefore, it contains different ingredients than two-stroke oils.

Use the right lubricant —Marine and auto oil are not interchangeable. Although oil in a four-stroke marine engine performs the same function as it does in an automobile engine, passenger car motor oil should not be used in marine engines. The two primary reasons for this: water and wear.
THE ANSWER IS NO!
Even if two different brands of oil have the same viscosity, you still should not be mixing them together.
The most important thing is to use oil that's the right thickness, or viscosity, for your car's engine. Oil that's too thick or thin won't provide the necessary protection for your engine, which can result in costly damage.
SAVSOL Ultra 4T 10W-30 API SL JASO MA2 Engine Oil for Four-Stroke High Performance Bikes (900 ml) The Savsol Engine Oil is efficiently suitable for four-stroke bikes for high performance. The Savsol Engine Oil is efficiently suitable for four-stroke bikes for high performance.
There is no difference between 4-cycle oil and regular engine oil; they are the same. Common engine oils used in lawnmowers are SAE30, 5W30, and 10W30.
WHAT ABOUT MIXING ENGINE OIL BRANDS? Yes. It won't harm your engine to mix, for example, Quaker State® motor oil with Pennzoil, as long as the oil you use is the weight (or viscosity) recommended in your vehicle owner's manual.
The SAE 5W-30 is a 4-stroke multi-grade oil. “5W″ indicates the viscosity of the oil at low temperatures and the number 30 indicates the viscosity at 100°C: this means that SAE 5W-30 guarantees high performance between -20° and +40°.
Is 4-stroke mower oil the same as car oil?
Four-cycle motors are common in lawn mowers, riding mowers and garden tractors. Like automobiles, these motors store gasoline and oil separately. They use the same oil as automobiles, but owners should check manuals because these small engines are sensitive to additives and alternatives.
Four-stroke (four-cycle) engines are newer and have a separate compartment for oil, so you don't have to worry about mixing fuel.
Comma 4 Stroke 10w-40 is a semi synthetic engine oil designed for use in high performing air and water cooled 4 stroke engines. Particularly recommended for use in motorcycles fitted with wet clutches, however this oil is also suitable for use in other high revving engines.
“We recommend a synthetic blend, a combination of synthetic and conventional oils,” says David Greenwood, product planning manager for Suzuki Marine (suzukimarine.com), which switched its company branded oil from conventional to a synthetic blend two years ago for its four-stroke outboards.
Marine and automotive engine oils are NOT interchangeable, why? The two primary reasons for this: water and wear. Consider that corrosion caused by water is a primary concern for marine engines.
Yes. There is no danger mixing synthetic and conventional motor oil. However, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits.
Yes, you can safely mix synthetic and conventional oil. All motor oil, whether synthetic or conventional, is a combination of base oils and additives. Each are designed to be used in the same applications, so they each pass the same minimum standards.
Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine.
Using the wrong engine oil can cause the metal parts of your engine to shear, making additional noise, and leaving metal shavings in your engine oil. If the temperature has been very cold, you might also be in for some trouble.
Modern synthetic oil is safe to use in all types of vehicles, ranging from new purchases to classics to aging not-so-classics. The idea that synthetic oil could harm old engines probably comes from a time before synthetic oils had been extensively tested.
Is Thicker oil better for old engines?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil - 10W - can help protect worn engine bearings as well.
For this reason, the four-stroke lubricants are much more similar to those of your regular car and they come in oil grades. AMSOIL´s 10W-40 Synthetic Dirt Bike Oil is highly recommended for Honda, Yamaha, Kawasaki, Suzuki, Husqvarna and other dirt bikes where 10W-40 motorcycle oil is used.
Small Engine Four Stroke Multigrade 10W-30 is suitable for use in lawnmowers, generator sets and pumps, four stroke outboards / inboards, four stroke brushcutters and in other gardening equipment that specify this viscosity grade.
Too much oil in the engine can also cause the pressure on the crankshaft to increase, causing oil to enter the exhaust pipe from the crankshaft into the combustion chamber, blocking the combustion chamber hole with oil and eventually clogging the engine. Wet spark plug; excess oil will also flood the spark plug well.
There's not much difference between 10W-30 and 10W-40 motor oil. What sets them apart has more to do with temperature fluctuations and engine load. For moderate weather, either engine oil grades should work fine. Your choices will become more critical when you start getting into high-heat situations.
4-stroke (or 4-cycle) oil is engine oil designed to be used in the crankcase of 4-cycle engines. 2-cycle oil, in contrast, is for mixing in the gasoline to be used in 2-cycle gasoline engines.
You can add any engine oil as long as it has the right specifications — preferably with an official approval of the OEM (Original Equipment Manufacturer). Not the brand, but the specification and viscosity indicated in your car's manual are your reference for using the right oil.
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.
While full synthetic may be more expensive, it will be stronger and provide better performance. As well, It will last longer, so you don't have to get your oil changed as often. Synthetic blend oil is more affordable but will not provide the same great performance that comes with full synthetic.
The SAE 30 4-stroke oil guarantees excellent performance and viscosity at temperatures between -5° and +40°. The API SL/CF specifications mean that it is suitable for both petrol and diesel engines and is indicated for lawn mowers and garden tractors, also of the front-cut ride-on type.
What viscosity is 4-stroke oil?
The following general recommendations apply [4]: SAE viscosity grade motor oil: 5W– 30; Temperature conditions: Below -18°C; Description: Provides excellent fuel economy and low temperature performance in most late–model engines. It is especially recommended for new car engines.
4T is a high quality, mineral based motorcycle oil designed for 4-stroke engines.
It is possible to run a vehicle on cooking oil – if you process it into biodiesel first. As a renewable and clean-burning alternative to petroleum, biodiesel is paving the way to a healthier planet with more sustainable fuel practices. If you plan to make the switch, consider SeQuential for your biodiesel needs.
What Type of Oil do I use in my Lawn Mower? The short answer is yes, you can sometimes use the same oil that you use in your car in your lawn mower.
Answer. I would use either Mobil 1™ 10W-30 or Mobil 1™ Extended Performance 10W-30. Either product will provide great protection for your lawn mower.
A 4T Oil is not designed to do so. As a result, when a 4T Oil is put into in a 2T Engine, it causes spark-plug fouling, exhaust port blockage, smoke emissions etc.
Adding mixed gas to a four-stroke engine will not damage it when it is done in small quantities. Adding large amounts of mixed gas to a four-stroke engine may potentially gum up the spark plug and damage it and can also result in lowered performance; thus, it should be avoided.
Not adding oil to the crankcase of a 4 stroke engine and using “2 stroke gas” will result in engine seizure. The cylinder bores and pistons might survive but the connecting rod and crankshaft bearings will rapidly overheat and seize, all internal moving parts will be damaged.
The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature.
In a nutshell – you should definitely use motorcycle specific oil if that's what your motorcycle recommends, but in a pinch, car oil could work okay. Just be sure the weight is correct.
What is the difference between marine 4 stroke oil and automotive oil?
Marine oil is formulated and designed for the harshest saltwater environment. Automotive oils don't operate in the constantly corrosive environment that boats do, so marine oils have much higher levels of anti-corrosive additives in them.
Valvoline™ 4 Stroke Outboard 10W-40 Oil is a premium semi synthetic engine oil designed to meet the requirements of NMMA FC-W specification. Valvoline 4 Stroke Outboard 10W-40 Oil is formulated for both air and water-cooled 4 stroke outboard engines.
Automotive oil definitely does not belong in the sump of your marine engine – outboard, sterndrive or inboard.
Marine engine oils are made so they resist strain, corrosion, and moisture at higher levels than automotive engine oils. They feature extremely strong film strength so that engine parts are protected during constant shear and load, while they also contain anti-oxidants pertinent for engine lifespan extension.
Quicksilver's all-inclusive 4-stroke oil and changing kit is a great choice for easy marine oil changes. It's an inexpensive kit that's simple to use, convenient in nature, and perfect for all marine 4-stroke engines However it has been made with Mercury Mariner engines in mind.
Synthetic vs Conventional Marine Oil
While synthetic marine oil is often much costlier than conventional oil, it brings numerous benefits. Synthetic oil can help your engine run more smoothly, even helping to increase the time between marine diesel engine maintenance visits.
Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so. Contrary to what some believe, adding synthetic oil to regular oil won't harm the engine, but there's also no benefit in doing so.
Four-stroke (four-cycle) engines are newer and have a separate compartment for oil, so you don't have to worry about mixing fuel.
Can You Mix Conventional Oil With Synthetic? The short answer is yes. There is no danger or risk of combustion, and mixing the two types of oil won't harm your engine. However, it's important to note that if you do mix the two, the conventional oil can keep the synthetic from performing to its fullest potential.
“Too much oil can damage your engine. If you notice an overfill of oil, the excess should be drained out of the engine. Therefore, we recommend checking your dipstick regularly.”
Will thinner oils damage your engine?
It's best to use the oil viscosity recommended in the owner's manual, but using a slightly thinner or thicker oil (lighter or heavier viscosity) generally poses no long-term harm.
Engine damage – Too much lubricant in the system can cause pressure on the crankshaft to increase. This can result in oil entering the crankshaft exhaust pipe, running through into the combustion chamber, blocking the suction hose with oil soot and potentially leading to engine overload.
Thick, very dark, or black engine oil usually indicates that your oil has been exposed to dirt or dust contaminants that lead to a soot build-up. Direct injection gasoline engines produce soot over time that causes standard motor oil to turn black and thick.
When you mix new and old oil, the new oil becomes “watered down” with the lack of interfacial tension and strains to do its' job. Be sure to have your oil changed as soon as possible.
There is no difference between 4-cycle oil and regular engine oil; they are the same. Common engine oils used in lawnmowers are SAE30, 5W30, and 10W30.
