Can I put 10W40 in a 5w30 engine?
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.
Can I use 20w40 instead of 5w30?
Use in Cars 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.
What happens if I put 10W40 instead of 5W20?
And a 10W40 would invalidate your warranty… just so you know. In a 5W20 engine. You could use a 0W20 oil (I use 0W20 oil) in cold weather and it would be Ok by Ford. (they will not say it is good, but they will still honor the warranty..)
What happens if you put 10W 30 instead of 5w-30?
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.
Which oil is thicker 5w30 or 10w40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
What would be an example of an API rating?
The service rating is shown in the API “Service Symbol Donut” on the product label. Whereas the labeling on the bottle of engine oil may suggest the product is a 10W-30, note, if there is no “W” between the 10 and the 30 it may not be a 10W-30. As an example, a SAE 10-30 is not the same as an SAE 10W30.
Is 5w30 oil synthetic?
Mobil 1 5W-30 is an advanced full synthetic engine oil designed to keep your engine running like new by providing exceptional wear protection, cleaning power and overall performance.
Do high-mileage engines need thicker oil?
Identification. For an older, high-mileage passenger car, it is recommended to switch to a thicker viscosity oil, such as 10W-30, when approaching and passing 100,000 miles, to lubricate the engine well for preservation.
Is it bad to use 10W oil instead of 5W?
If additional information can help with a verdict; the engine has relatively low mileage (~98k) but it has been neglected (it was recently run for several months to a year with a leaky intake manifold gasket where coolant was able to contaminate the oil). Especially given that you live in Florida, 10W-30 vs 5W-30 is not an issue at all.
Can you use 0W-20 mineral oil on a Toyota?
Vehicles in which 0w-20 is an option to 5w-20 mineral oil, (or 5w-30), will continue to require 5,000-mile/6-month oil change intervals, even if 0w-20 oil is used. In the case of vehicles with 10,000-mile oil change intervals, the 5,000-mile service interval has not been eliminated.
What kind of oil does a 10W30 engine take?
10w30 motor oil should have an ACEA A3/B4 or A3/B3 rating, according to the European Automobile Manufacturers Association. The association is responsible for assigning oil sequences for various specifications of engine oils.
What happens when you use 0w40 oil in an engine?
If you use a thicker oil when the engine is hot the oil flows slower. This means the oil spends more residence time in critical engine components and doesn’t remove the heat as quickly as the thinner oil because it flows faster. For those 2 vehicles I would not go with 0W40 synthetic (European spec) from Mobil.
