How much does oil viscosity affect gas mileage?
You could save as much as 1 percent on your fuel economy simply by switching from a 15W-40 engine oil to a 10W-30 engine oil, according to new research from Chevron Oronite..
Does thicker oil make your car slower?
yes it does affect performance. Just think about it, the oil is thicker than oem so it is going to require a little more force than usual working more than what it has to.
How often should you change engine oil?
It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles. Moreover, if your car’s engine requires full-synthetic motor oil, it might go as far as 15,000 miles between services!
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.
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.
Is it better to use thicker oil?
Within reason, thicker oil generally maintains a better film of lubrication between moving parts and seals vital components of your engine better. … The more resistant oil is to thinning, the higher the second number (10W-40 versus 10W-30, for example) will be, and that’s good.
What happens if you put 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
Can you go 10000 miles with synthetic oil?
If your car’s manufacturer recommends synthetic oil, or if you decide to make the switch, you could go as many as 10,000 miles or more between oil changes. … While some experts suggest doing it in most circumstances, Consumer Reports says that, generally, you shouldn’t switch to synthetic if your car doesn’t need it.
Can I mix synthetic and regular oil?
Yes, you can safely mix synthetic and conventional oil. … In the end, conventional and synthetic oils are completely compatible. However while you can safely mix synthetic and conventional oils, you’re diluting the performance of the synthetic oil.
What is 20w50 oil used for?
A 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.
Will thicker oil leak less?
As an engine heats up, the oil thins, becoming more susceptible to leaks through faulty gaskets. Draining the oil from your vehicle and replacing it with a thicker weight or synthetic oil can help to prevent oil from leaking through some of the smaller breaks in the gasket seals.
How often should you change synthetic oil?
5,000 miles to 7,500 milesSynthetic Oil Change Interval If you are using synthetic oil, the interval between oil changes can be extended. Manufacturer recommendations range from 5,000 miles to 7,500 miles, on average. Some recommended intervals might be shorter or longer.
Does oil type affect gas mileage?
As engine oil ages, it breaks down. … Without proper viscosity, the lubrication abilities of the oil are useless because it can’t get where it needs to go. As these properties are lost the engine will run hotter and less efficiently, which negatively effects gas mileage.
What is the best engine oil additive?

What are the disadvantages of synthetic oil?
Disadvantages of Synthetic Motor OilMany of the synthetic oil blends reduce friction better than conventional motor oil. … Synthetic oil does not hold lead in the suspension of the oil. … Problems with racecar type engines using roller lifters. … Synthetic oil has different disposal methods.More items…•
Do you get better mileage with synthetic oil?
Synthetic motor oils have oil molecules of a small uniform size as compared with those of regular non-synthetic oils. This decreases friction and improves fuel economy. Synthetic motor oils vary but some companies claim gains of up to 5% in fuel economy just by switching your stock motor oil to their synthetic brand.
Is full synthetic oil worth it?
Though synthetics generally hold up better for more miles, regular oil changes remain important, and you shouldn’t wait beyond the time interval recommended by the manufacturer—typically every six months or a year. Using synthetic in these situations will prolong your oil life and require fewer changes.
Which is more fuel efficient 10w30 or 10w40 engine oil?
The kind of oil that you use will affect your vehicle’s gas consumption. Between these two oil types, the 10W30 will offer much better fuel economy than 10W40. … What makes 10W30 more fuel-efficient is the fact that it is thinner, and hence it will allow the engine components to move effortlessly and work less.
Is it OK to use 0w20 instead of 5w30?
0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine. 0w-20 may be a recommended oil for certain conditions for your engine and may not be recommended for your engine.
Can you switch back to conventional oil after using 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.
Is synthetic oil thinner?
When the additives wear out in a synthetic oil it still has the same viscosity. It will not thin as a mineral oil.
