What can I use instead of 5w30?
When to Use 10w30 vs 5w30 The only difference between these two oils is cold flow ability: a 10w30 oil will move slower than a 5w30 oil during cold startups.
At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically..
Can I put 5w40 in my BMW?
The Castrol oil that BMW used to spec was midway between a 30 and 40 weight. Anything from 0W30 to 5W40 will be fine if it has the LL-98 or LL-01 rating. You don’t even need that if you are running shorter change intervals.
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.
What happens if I 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.
What is the best oil for high mileage?
The Best High Mileage OilValvoline High Mileage Motor Oil. … Castrol GTX High Mileage Synthetic Motor Oil. … Mobil 1 High Mileage 5W-30 Motor Oil. … Pennzoil High Mileage Oil. … Castrol High Mileage Advanced Full Synthetic Motor Oil. … Royal Purple High-Mileage Synthetic Motor Oil. … AmazonBasics High Mileage Motor Oil. … Mobil 1 High Mileage 5W-20 Motor Oil.
Is 5w40 better than 5w30?
5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.
Will 5w30 hurt a 5w40 engine?
If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30. However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts.
Is 5w30 good for high mileage?
Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same. However, 5w30 flows much better than 10w30 during cold starts.
What happens if you put the wrong kind of 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.
Whats thicker 5w30 or 5w40?
Viscosity The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30. So, 5w30 is better than 5w40.
Do high mileage cars need thicker oil?
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.
Can I switch from 5w40 to 5w30?
In most cases, if they recommend SAE 5W-40, then SAE 5W-30 may cause problems with wear or even engine damage. SAE 5W-40 will always be “Thin” enough at any temperature, but SAE 5W-30 may be too “Thin” at high temperatures.
Is it bad to go from 10w30 to 5w30?
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.
Is mixing 5w30 with 10w30 bad?
Mixing different oils will not improve the performance or efficiency of the engine in any way. … 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature. The 5w30 is better because it thickens less when cool or cold. Thinner oil gets to the top end faster.
Will thicker oil damage my engine?
Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.
Is it OK to use 15w40 instead of 5w30?
5w30 flows better than 15w40. 5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No it won’t blow off,you will just wear your engine out quicker because the oil won’t flow to the moving parts as quickly !
