SAE 5W-30 describes the oil’s viscosity grade. The 5W refers to low-temperature test requirements, and 30 describes the viscosity grade at higher temperatures.
Two oils with this grade can meet different performance specifications. Check the specifications your engine manufacturer lists before choosing.

The SAE grade (5W-30) tells you the viscosity. The performance category tells you what the oil actually protects against: wear, deposits, oxidation, sludge, and emissions system compatibility.
The American Petroleum Institute (API) publishes service categories. If your manual specifies an API category, check the oil’s stated category and any other requirements in the manual.
A manual may also specify an ACEA classification or an engine-manufacturer specification. Check each requirement that applies to your vehicle.
Two 5W-30 oils can have completely different performance categories. One might carry API SP with ACEA A5/B5; another might carry API SQ with ACEA C3-21. The grade is the same, but the chemistry and the engines they suit are different.

Start with the specifications in your vehicle manual. Follow these four steps before your next oil change.
If the manual is missing, the manufacturer's website or authorised dealer can supply the specification. Do not rely on generic online fitment guides that match by car model alone without the engine code.
DTOX lists four 5W-30 options in its product range. These examples illustrate how products with the same SAE grade can have different stated specifications.
DTOX lists API SP for this grade, with ACEA A5/B5 and MB 229.61 among its published performance claims.

Group IV PAO base oils with Triple Ester chemistry, the DTOX flagship. Carries API SP and ACEA A3/B4 as DTOX performance claims.
Advanced fully synthetic with Molecular-Shield friction modifiers in a Mid-SAPS formulation. Carries API SQ and ACEA C3-21 as DTOX performance claims.
Performance claims and fitment recommendations above are as published by DTOX on their product data sheets. Confirm the specification against your vehicle manual before choosing.
Dalam Bahasa Malaysia5W-30 ialah gred kelikatan SAE, bukan penarafan kualiti. Semak manual kenderaan untuk gred SAE yang dibenarkan dan kategori prestasi minimum (contoh: API SP, ACEA A5/B5) sebelum memilih minyak enjin. Kru DTOX mengesahkan gred yang sesuai untuk kereta anda sebelum kerja bermula.
