Can I use 20W50 instead of 5w30? 20W-50 is thicker than 30 weight oils, which can cause wear and tear on newer or older cars because it takes time before they flow freely through all cylinders at once; this means that
you should only substitute one grade up when switching from 5w30 motor gasoline
(or vice versa).
Can I use 20W50 oil instead of 5W-30?
A 5W-30 oil is commonly used in passenger cars for normal use throughout the year.
A 20W-50 oil will not protect a car as well in a cold winter and its greater viscosity will increase drag and friction in a passenger vehicle
.
Will 20W50 oil harm my engine?
Most modern car engines are not well suited for heavier oil like 20W-50, and
it can damage your car’s catalytic converters
. 20W-50 oil does not have a reliable low temperature viscosity grade. It won’t perform well in cold weather and will deliver below-average cold starts.
What can you use instead of 5W-30?
Both 5w30 and
10w30
engine oils have a similar SAE rating, meaning that they will perform the same at high or operating temperatures. The digit 30 indicates the viscosity of the oils when in high temperatures. 10w30, however, will thicken more when in a cold climate. 5w30 is much suitable during the cold season.
When should I use 20W-50 oil?
A SAE 20W-50 motor oil is
typically used in older vehicles or in particularly warm climates
. Castrol GTX 20W-50 has been specially formulated to help extend the life of your engine by keeping it free from sludge, even when operating in extremely high temperatures.
Is 20W50 good for petrol engine?
Suitable Vehicles
Depending on the recommendations for the particular vehicle,
20W50 oil is suitable for large or small diesel engines, gasoline engines
, motorcycles and aviation vehicles. It is also suitable for both air- and liquid-cooled engines.
Can thick oil damage 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
.
Is Thicker oil better for high mileage cars?
The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well. As long as you’re not hearing knocking or serious mechanical noises from the engine,
the heavier oil should buy you many more miles of service from your vehicle
.
Can I use 20W40 instead of 5w30?
5w30 will float over 20w40 oil
. This will create burning smell and may cause uneven oil temperature.
What is 20W 40 oil used for?
20W40, similar to other motor oil with different grading, is used for
engine lubrication, protection against rust and corrosion, and keeping the engine clean
.
What happens if I put 10w40 instead of 5W-30?
Your vehicle does not use 5W-30 oil
. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
What happens if you put the wrong weight oil in your car?
You might notice a few oil spot in your garage or under your car because
using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving
. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.
Will thicker oil increase oil pressure?
What is the thickest oil I can put in my car?
Importance of a Viscosity Scale
In order to have a standard way to measure the viscosity of engine oil, the Society of Automotive Engineers (SAE) developed a viscosity scale. The scale ranges from 0W, which is the thinnest type of oil, to a rating of
60
, which is the thickest oil.
Can I use 20w50 instead of 10w30?
It really comes down to personal preference.
As your engine does put out significant horsepower, we would lean toward using 20W-50
. If your engine sees very light duty or is built exceptionally tight, 10W-30 would be fine. But again, if you twisted our arm, we would give 20W-50 the nod for the thicker viscosity.
Can I use 20w50 instead of SAE 30?
As I was getting at in the above section,
no, SAE 30 is not the same as 20w50
. They are actually very different types of motor oil. The biggest difference is that SAE 30 is only rated for its viscosity one time while hot. This is because SAE 30 is only intended for use in engines that don’t need to start in the cold.
What is 20W 20 oil used for?
MOTOR OIL EXTRA SAE 20W/20 is suitable for
vehicles, motorbikes and stationary systems that are operated with monograde motor oils
. EXTRA monograde oils can also be used in specific gears and hydraulic systems for which monograde motor oils are required.
Is 20W 50 semi synthetic?
Description.
Semi-synthetic
engine oil for petrol and diesel engines. Because of the high viscosity index, the oil assures an excellent cold start as well as a strong lubricating film at high temperatures.
Which engine oil is best for old car?
Monograde oils
are still widely available, primarily because they’re used in very hot climates, or in heavy-duty applications such as mining or construction equipment. These single-grade oils can be used in 1950s and older cars – generally SAE 30 to SAE 50 – but most owners use multi-grade.

When should I use thicker oil?
There are some circumstances where drivers have used thicker oil in an engine. If, for instance,
clearances between engine components have increased, gotten sloppy
, a thicker oil can help to fill the void. Within reason, thicker oil maintains a better lubricant film between moving parts.
Is it OK to mix brands of motor oil?
THE ANSWER IS NO!
Even if two different brands of oil have the same viscosity,
you still should not be mixing them together
.
What oil is thicker than 20w50?
10w40 oil
is typically thicker than 20w50 oil. This means that it will not fit as well into your engine. Many people believe that 10w40 oil is not an all-purpose oil but a supplemental oil for cars only.
What oil can I use instead of 20w50?
Re: Substitute For 20W-50 engine oil?
5w50, 15w50 and 10w60
tend to be the alternatives.
Can we use 15W40 instead of 5W-30?
No, you won’t blow a head gasket, but
15W40 is too heavy an oil to use where 5W30 is required
. Besides, most 15W40 oils are gor diesel engines. Your oil flow will get disturbed.
What happens if I use 20W50 instead of 20W40?
20W50 will hold on to the viscosity marginally better than 20W40 when the engine gets hot. However,
20W50 mineral oil will cause more sludge than a similar 20W40 because 20W50 will have more viscosity improvers
. Pulsar 150’s manual recommends 20W40, but you can use either, not much of a difference.
Is it OK to use 20W50 instead of 20W40?
But even so, both vary in their properties. The main objective of engine oil is to support the engine’s smooth performance with proper lubrication and cleaning.
20W40 is suitable for hotter climates and will not cause sludge as opposed to 20w50 which is more appropriate for hotter conditions
.
Which is better 10w 30 or 20w 40?
20w 40 is a thicker oil when compared to the original 10w 30 oil. So
10w 30 oil is going to flow better than 20w40 oil
when you initially start it and also run it. If the oil flows better the better the oil will lubricate and protect engine parts.
Does thicker oil burn less?
Is 10w40 and 5W-30 the same?
5w30 motor oil is synthetic motor oil that has a viscosity of 5 in low temperatures and viscosity of 30 at higher temperatures, usually 100 degree Celsius. 10w40 motor oil is synthetic motor oil that has a viscosity of 10 in low temperatures and viscosity of 40 at higher temperatures, usually 100 degree Celsius.
Can you run 10w30 instead of 5W-30?
According to API motor oil guide [1],
If you are using 10W–30, you can safely switch to 5W–30
(in car engines). 5W–30 is thinner than 10W–30 when cold. (you must follow the manufacturer’s recommendations). However, switching from 5W–30 to economical 10W–30 is not always recommended.
Why does my car smoke after oil change?
Why can’t you go back to regular oil after synthetic?
Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact,
synthetic blends are simply a mixture of synthetic and conventional oils
.
Can you mix motor oil weights?
Given that standards are in place, does that mean you can mix and match oil weights? The truth is simple:
don’t mix two different oils that have different weights
(viscosities). Viscosity Grades might sound pretty scientific, but the simple fact is that this is what keeps your engine running smoothly.
