Best Engine Oil for Popular Cars in Singapore (2025 Guide)
Choosing the right engine oil isn’t just about ticking off a service checklist - it directly impacts your car’s performance, fuel economy, engine health, and long-term maintenance costs. Yet for many drivers in Singapore, understanding what all those numbers (like 0W-20 or 5W-40) actually mean - and what oil their car truly needs - can feel unnecessarily complicated.
The truth is, there’s no such thing as “one oil fits all.” Every vehicle is designed to run on a specific engine oil viscosity, set by the manufacturer based on the engine’s design, operating temperature, and efficiency goals. Using the wrong oil grade could lead to reduced performance, engine wear, or even warranty issues.
In this guide, we’ll break down:
- What SAE viscosity ratings like 0W-20 and 5W-30 really mean
- Which engine oil grades are recommended for Singapore’s most common car models
- And where to get manufacturer-approved engine oils and servicing done right — without guesswork
If you're unsure about what’s currently in your car or when your last proper oil change was, this guide will help you get back on track.
What Does SAE 0W-20 or 5W-40 Actually Mean?
At first glance, engine oil grades like SAE 0W-20 or 5W-40 might look like random codes — but they actually tell you everything about how the oil performs under different conditions.
What is SAE?
SAE stands for the Society of Automotive Engineers, the body that standardises engine oil viscosity ratings worldwide. These ratings help you understand how thick or thin an oil is at different temperatures.
Breaking Down the Numbers
Let’s take 5W-30 as an example.
- 5W (the number before the “W”) refers to the oil’s viscosity at cold temperatures — the “W” stands for Winter. The lower the number, the thinner the oil when your engine is cold. This allows the oil to circulate more quickly during startup, reducing engine wear.
- 30 (the second number) represents the oil’s viscosity at normal engine operating temperatures. A higher number means the oil is thicker when hot, offering better protection in high-load or high-temperature conditions.
How Does This Affect Your Car?
Using the right oil viscosity ensures:
- Smoother cold starts
- Proper lubrication at all temperatures
- Lower internal friction, leading to better fuel economy
- Reduced engine wear, especially in Singapore’s stop-start traffic
Using an oil that’s too thick or too thin can lead to increased wear, sluggish performance, or even engine damage over time - especially in vehicles with turbochargers or hybrid systems that have more specific oil requirements.
Engine Oil Recommendations for Singapore’s Most Common Car Models
Whether you’re driving a Japanese hybrid or a turbocharged continental sedan, your car’s engine is designed to run on a very specific grade of oil — and sticking to that recommendation is essential for longevity, efficiency, and manufacturer warranty compliance.
Here are the manufacturer-recommended engine oil grades for some of the most common cars on Singapore roads:
Toyota Corolla Altis – SAE 0W-20
Best engine oil for Toyota Altis in Singapore
- Recommended oil grade: SAE 0W-20
- Type: Fully synthetic
- Why it matters: Toyota specifically recommends 0W-20 for the Corolla Altis due to its ability to improve fuel economy and reduce engine wear during start-stop city driving.
- Tip: If you drive mostly short-distance or in heavy traffic, a low-viscosity oil like 0W-20 helps your engine operate more efficiently.
Honda Vezel (Hybrid) – SAE 0W-20

Recommended engine oil for Honda Vezel hybrid
- Recommended oil grade: SAE 0W-20
- Type: Fully synthetic
- Why it matters: Hybrid systems like the Vezel’s have frequent engine starts and stops, which benefit from thinner oil that flows quickly. 0W-20 reduces friction, supports smoother acceleration, and helps with hybrid system integration.
- Caution: Avoid switching to thicker oil grades (like 5W-30) unless specifically approved — it may reduce efficiency.
Mazda 3 (SkyActiv) – SAE 5W-30

Best engine oil for Mazda 3 SkyActiv engines
- Recommended oil grade: SAE 5W-30
- Type: Fully synthetic
- Why it matters: Mazda’s SkyActiv engines are tuned for combustion efficiency. 5W-30 maintains stability under load and helps reduce carbon build-up — especially important if you're driving at higher RPMs or on expressways.
- Additional note: Some variants allow for 0W-20, but 5W-30 offers broader thermal protection.
Hyundai Avante – SAE 5W-30
Recommended engine oil for Hyundai Avante Singapore
- Recommended oil grade: SAE 5W-30
- Type: Fully synthetic
- Why it matters: For both the Avante’s 1.6L and 2.0L variants, 5W-30 is the most commonly recommended grade. It provides a balance between fuel efficiency and high-temperature stability, making it ideal for Singapore’s climate and urban conditions.
- Good to know: Some newer models may list 0W-20 as an alternative for improved fuel economy, but 5W-30 remains the safer all-rounder.
Mercedes-Benz C-Class (W205 – C180 / C200) – SAE 5W-40
Engine oil recommendation for Mercedes-Benz C-Class W205
- Recommended oil grade: SAE 5W-40
- Spec: MB-Approval 229.5 or 229.51
- Why it matters: These turbocharged engines operate at higher temperatures and require oil that can handle thermal stress. 5W-40 provides the necessary viscosity and protection while complying with Mercedes-Benz’s strict specifications.
- Important: Always ensure the oil meets MB-Approval standards. Using the wrong spec may affect your engine’s long-term performance.
BMW 3 Series (F30 – 316i / 320i) – SAE 5W-30
Best engine oil for BMW 3 Series F30 Singapore
- Recommended oil grade: SAE 5W-30
- Spec: BMW Longlife-01 (LL-01) or LL-04
- Why it matters: These BMW models use turbocharged, direct-injection engines that benefit from low-ash, high-stability oil. 5W-30 balances fuel efficiency with wear protection, while LL-01 and LL-04 standards ensure engine cleanliness and extended drain intervals.
- Pro tip: LL-04 oils are preferred if your vehicle has a diesel particulate filter (DPF), though LL-01 is common for petrol models in Singapore.
