Nope . SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. The W stands for ‘Winter'. Note that these viscosities are relative, and standardised numbers and no absolutes, the oil doesn't get thicker when it's hot, it gets thinner.
What is SAE 30 SF oil?
SAE 30 oil is a motor oil that has been given a viscosity rating of 30 by the Society of Automotive Engineers, according to AA1Car Automotive Diagnostic Help Center. Motor oils typically have ratings from 0 to 50.
What does SF stand for in oil?
Now the letters. An API service rating of “SF” means the oil meets all new car warranty requirements for 1981 and newer models. “SE” means the oil is usable in all 1972-1980 vehicles. “SD” means the oil is good for all 1968-1971 cars.
Can I use SN oil instead of SF?
The “S” series is composed of SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM and SN. SN oils provide higher levels of performance than all the other “S” oils. API Categories SA through SH are obsolete, and oils labelled SN can be used in their place.
What is SAE number in oil?
SAE number, code for specifying the viscosity of lubricating oil , established by the U.S. Society of Automotive Engineers. The numbers for crankcase lubricants range from 5 to 50, for transmission and axle lubricants they range from 75 to 250; the lower the number, the more readily the oil flows.
Is SAE 30 the same as 10W30?
Yes , you can make use 10W30 engine oil instead of the SAE30 in your Lawn Mower. ... Older engines can use the SAE30, while the 10W30 is for modern engines. Again, the SAE30 is better for warmer temperatures while the 10W30 is suitable for varying temperature ranges and also works well in cold weather.
Is SJ oil better than SG?
In summary, API SJ represents an improved quality level of motor oil vs API SH. API SJ oils can be used in any applications where SH oils were being appropriately used. So if your owner's manual calls for an API SE, SF, SG or SH motor oil – API SJ will work just fine.
What is the difference between SAE 20 and SAE 30 oil?
SAE 20 is somewhat closer to 30 than the other jumps , because SAE 30 must be 30°F higher than SAE 20 to be roughly the equivalent viscosity. In other words, an SAE 20 at 190°F is about the same kinematic viscosity as an SAE 30 at 220°F, which is about the same viscosity as an SAE 40 at 240°F.
Is SAE 30 Good for lawn mower?
For most mowers and weather conditions, your best bet is going to be SAE 30/ SAE 10W-30 oil . These oils are ideal for operation in warmer environments. Even if you live in a colder area, chances are you aren't going to be operating your lawn care equipment until it's warm again.
What oil is thicker than SAE 30?
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.
What is API SJ?
API Service Category SJ was first introduced in 1996 for use in gasoline engines and is not suitable for use in engines introduced after 2001. API SJ oils are typically high HTHS (≥ 3.5cP) SAE 10W-40, 15W-40 and 20W-50 based on API Group I or Group II base oils.
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.
What is API SL?
2001 Gasoline Engine Service . Category SL was adopted to describe engine oils for use in 2001. It is for use in service typical of gasoline engines in present and earlier passenger cars, sports utility vehicles, vans and light trucks operating under vehicle manufacturers recommended maintenance procedures.
Is SAE 5W-20 a synthetic oil?
Keeps engines running like new
Mobil 1 5W-20 advanced full synthetic motor oil is designed to deliver outstanding engine protection, keep your engine running like new and protect critical engine parts for up to 10,000 miles between oil changes.
How do you read SAE oil?
This is why you would see something like this on the label: SAE 5W-30 . In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil's cold temperature/ cold start performance.
What does SAE 5W-20 stand for?
Here's an example: 5W-20. 5: This is the oil's viscosity rating at low or winter temperatures . W: This stands for “winter,” and is part of the “5” rating. 20: This is the oil's viscosity rating at high temperatures.
