Can you mix 5w 30 and 10w 40? As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40. Mixing different oils will not improve the performance or efficiency of the engine in any way.

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 will happen if I put the wrong oil in my 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 10w40 hurt a 5w40 engine?
Yes. 10w40 is thicker than 5w40, it will not lubricate all the parts that need lubricating from cold.
Will 5w30 hurt a 5w40 engine?
What would happen if I use 5w30 oil instead of 5w40 in my car engine
Which oil is thicker 5w30 or 10w40?
5w30 is less viscous while 10w40 is more viscous. The 5w30 has a viscosity of 30 at high temperature while a 10w40 has a 40 viscosity at high temperatures. When at high temperatures, the 5w30 oil becomes thinner than the 10w40 oil since 30 is lower as compared to 40.
Is 10W40 good for high mileage?
Keep your engine running longer—and stronger.
With a unique blend of premium base oils and an enhanced additive system, PEAK® 10W-40 High Mileage Motor Oil exceeds the toughest automotive standards for engine protection and performance in today’s higher mileage vehicles.
And it will surpass your expectations too.
When should I use 10W40 oil?
Using the correct viscosity oil eases starting, reduces friction, and slows wear.
For even more effective start-up protection, use a synthetic 10W-40 instead of a conventional 20W-50.
The synthetic 10W-40 flows easily and still maintains enough viscosity to protect piston skirts and bearings when it gets hot.
What happens if I use 10W40 instead of 10W30?
Changing from 10W30 to 10W40 will not do any effect on your engine if you choose right one for the right season. Its totally safe you can go for it. Look at the owner’s manual that came with the vehicle and follow it’s specifications.
Is it OK to mix brands of oil?
Yes, you can safely mix one brand of oil (e.g. Mobil 1) with a different brand (e.g. AMSOIL) or conventional oil with synthetic oil (in fact, that’s what a synthetic blend is). Most synthetics today are fully compatible with conventional oils and can safely be mixed.
Can you mix 5W30 and 0w20?
Yes, just that.
Pennzoil Platinum is a thin 30 or Valvoline Advanced also in 5w-30.
Both syn oils.

Can you mix 5W30 and 5/20 oil?
It is entirely safe and okay to mix 5W30 and 5W20. Whether you’re topping your 5W30 engine with 5W20 oil or vice versa, you are definitely not triggering any harm or potential damage to the engine’s core components. Yes, the oils may have different additives; hence, the difference in their weight rating.
Should I use thicker oil in a high mileage engine?
High-mileage motor oil doesn’t hurt and it could prevent leaks from starting.
Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.
Is 5w30 good for high mileage?
Amazon Basics Full Synthetic is the best 5w30 oil for high mileage vehicles.
This oil should only be used on vehicles exceeding 75,000 miles.
This motor oil is formulated for longer drain intervals.
It helps in preventing a build-up on drain intervals and preventing rust and corrosion.
?
The designation “10W-40” indicates a multigrade oil that is toward the low end of the SAE scale in cold weather, but at the upper end in hot conditions.
10W-40 oil is therefore good for a wide range of weather conditions.
Does a car run better after an oil change?
Changing your oil offers a lot of noticeable benefits, as well. Regular oil changes improve your car’s gas mileage. As the fresh oil moves through the engine, the lubrication of the metal parts increases your engine’s performance and helps it run more efficiently with less work so it doesn’t eat up as much gas.
Will 5w30 hurt a 0w20 engine?
No, not true.
A 5W-30 full synthetic will flow fine.
If you look at the owner’s manual for the same Toyota engines in many other countries, they specify 5W-30 for better engine longevity.
The reason why they specify 0W-20 (and new cars are trying to go lower such as 0W-16) is for better gas mileage.
