When should I use 20w50 oil?
Warmer Temperatures 20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin.
It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers..
Should I use 5w20 or 5w30?
Most often, these types of oils best cover the range of possible temperatures, with a 5W-20 oil more geared toward colder climates and a 5W-30 oil more appropriate for warmer temperature extremes. For the most part, either one should work just fine in a vehicle engine regardless of the prevailing temperatures.
Is it bad to mix 5w30 with 10w30?
Mixing different oils will not improve the performance or efficiency of the engine in any way. The additives in synthetic oil may have limited or no effect at all when mixed with a regular engine oil. … 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature.
Is Thicker oil better for high mileage cars?
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.
Can I mix synthetic and regular oil?
The short answer is… yes. If you don’t have a choice, adding synthetic oil to regular oil can help you out in a pinch.
Will 5w30 hurt a 5w20 engine?
Recommended Services. Hello. Using 5W30 oil for your vehicle will not blow out the engine. However, your vehicle will not run as efficiently as it should and you may experience a loss of fuel economy.
Will it hurt to put 10w30 in a 5w20 engine?
Modern cars are designed to use lower viscosity oil ranges, so they can properly lubricate ( see attachment) Going from 5w-20 to 10w-30 should cause no harm for one oil change. But if you engine as designed for 5W-20, give it 5W-20.
Is it okay to mix engine oil?
The good news is that mixing different types of oil it will not harm your engine in any way in the short run. Most synthetic and semi-synthetic engine oils are based on regular oil and are compatible. … Now, as far as different grades are concerned, mixing between them isn’t something that will damage your engine either.
What’s the best motor oil for high mileage?
5 Best Motor Oils for High Mileage Engines#1 – Mobile 1 High Mileage Synthetic Oil.#2 – Royal Purple HMX Synthetic Oil.#3 – Mobile Super High Mileage Synthetic Oil.#4 – Castrol GTX High Mileage Synthetic Blend Oil.#5 – Pennzoil High Mileage Synthetic Blend Motor Oil.
Is 5w30 or 10w30 better for winter?
At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.
Which oil is thicker 10w40 or 10w30?
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. … Remember that using oil with a viscosity that is too high can result in excessive oil temperature and increased drag.
What happens if I put 10w30 instead of 5w30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
What happens if you put thicker oil in your car?
#4 – Poor Fuel Economy If you use too thick of a motor oil for the conditions, your fuel mileage will likely suffer. This is because the thicker oil increases resistance on moving parts such as pistons. While your engine will be protected, it will be at the expense of more frequent trips to the gas station.
What oil is best for old engines?
synthetic oilsFull 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.
Is 5w30 good for high mileage?
For example, a high mileage engine oil rated at 5W30 will flow better and has a superior viscosity at low temperatures when compared to an engine oil with a rating of 10W40. If you live in a cold environment, it is always best to go with a high mileage oil that has a lower SAE rating like 5W30.
Should I use thicker oil in an older engine?
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.
Which oil is thicker 5w30 or 5w20?
5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. … So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.
Can you switch from 5w30 to 10w30?
The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine. … You don’t really need to change to the 10W30. The 5W and 10W are the numbers that tell you the low temperature behavior of the oil and the second number tells you the high temperature behavior.
