A Honda ADV 160 is a capable little adventure scooter, but the wrong engine oil can turn your ride into a clunky, hesitant mess — especially when you first start on a cold morning. The oil you pour into its single-cylinder engine has to handle both the engine and the gearbox from a shared sump, so picking a formula that protects the wet clutch and keeps shifts smooth is the whole game. This guide breaks down four oils that ADV 160 owners actually run, with the exact specs that matter.

You want oil that your Honda ADV 160’s wet clutch (a clutch that runs in oil) can grip without slipping, that flows easily on a winter morning, and that holds up to the heat of a long summer ride — that is what this guide to the engine oil for adv 160 is built to deliver.
Our Picks at a Glance
How To Choose The Best Engine Oil for ADV 160
The ADV 160 shares its oil between the engine and the gearbox, so the standard rules for car oil do not apply. You need a 4-stroke motorcycle oil with the right JASO rating and the correct viscosity for your climate.
Start with the JASO MA2 rating
JASO MA2 is the friction standard that tells you the oil is safe for a wet clutch — the kind your ADV 160 uses. Without it, a standard car oil can make the clutch slip or grab unpredictably. Every oil on this list carries the JASO MA2 certification.
Pick the right viscosity grade
Your ADV 160 owner’s manual likely calls for 10W-30 or 10W-40 depending on the climate. A 10W-30 flows better in cold starts while a 5W-40, like the Motul Scooter Power, gives even better cold-flow plus a thicker hot film for high-temperature protection.
Decide between semi-synthetic and full synthetic
A semi-synthetic blend like the Motul 5100 brings Ester technology and strong film strength for a reasonable price. A full synthetic like the Motul Scooter Power offers the highest thermal stability and longest drain intervals. Pick your budget first, then the spec.

In‑Depth Reviews
1. Motul 5100 4T 10W-30 Motorcycle Oil
Our pick — over 4.5★ from 19,000+ verified ratings; the strongest balance of quality and price.
The semi-synthetic that kills the cold-start clunk and slides into neutral smoother than the factory fill.
This Motul 5100 uses ester-reinforced Technosynthese base stocks — meaning the oil film sticks to metal surfaces stubbornly, resisting shear even when your ADV 160’s engine is hot and screaming. It is certified JASO MA2 (T903:2023), so you get the precise friction the wet clutch needs without any slip. The measured flash point is 228 Degrees Celsius, giving you a big safety margin against oil breakdown under hard riding. Buyers report one consistent observation: “Shift into first while cold no longer clunks or lurches as did with Honda GN4.” That is a real, daily difference you feel at every stoplight.
At 4 Liters of liquid volume, you get four full oil changes for the ADV 160 (which takes about 0.9 quarts per change), so this one jug covers a full season or more. The 10W-30 viscosity is what most ADV 160 owner’s manuals call for. The item weight of 2.4 Kilograms versus the Motul Scooter Power’s 0.85 Kilograms (nearly three times heavier) reflects the larger container size, not a heavier oil.
Compared to the Honda GN4 oil below, the Motul 5100’s semi-synthetic build offers higher thermal resistance — the flash point (the temperature at which oil vapors ignite) gap of 228°C vs the GN4’s unlisted number (but the GN4 is a mineral oil, so the gap is significant). It also costs more per bottle, but the 4-liter jug makes the per-change cost competitive.
What makes it the top pick
- JASO MA2 certified for wet clutch safety — the latest 2023 standard
- Ester technology resists shearing at high RPM and high temperature
- 4-liter jug is enough for multiple oil changes on the ADV 160’s small sump
- Buyers praise the elimination of cold-start clunk and improved shifting
The trade-offs
- Higher upfront cost than a single-liter bottle of mineral oil
- 10W-30 may not suit extreme summer heat in some climates — check your manual
Reach for it if: you want noticeably smoother cold shifts and a semi-synthetic oil that outlasts the factory fill by a wide margin.
Look elsewhere if: you prefer the simplicity of a Honda-specified mineral oil for warranty confidence.
2. Honda Pro Oils Honda GN4 Motor Oil – 10W30 – 4 Quarts
The factory-fill oil that Honda’s own engineers blended — no guesswork, no compatibility worries.
This is Pro Honda GN4 Motor Oil, OEM part number 08C35-A131M02, engineered by Honda R&D specifically for Honda 4-Stroke motorcycles, ATVs, and scooters — your ADV 160 included. It uses a blend of shear-stable polymer additives with top quality base stocks to resist viscosity breakdown and thermal breakdown. Since it is the same oil your owner’s manual recommends, you get zero compatibility anxiety: it exceeds all requirements for API service classifications SJ and all Honda warranty standards.
The SAE J300 viscosity grade is 10W-30, matching the ADV 160’s factory spec. You get a pack of 4 Quarts (128 Fluid Ounces total), which covers roughly four oil changes for the ADV 160. Reviewers on Honda CB650R and CBR650R bikes report it works perfectly. One reviewer noted that the 4-quart pack was cheaper than a single 4-quart jug — a small money-saving detail.
Compared to the Motul 5100 above, the GN4 is a mineral oil — it lacks the Ester technology and the higher flash point of a semi-synthetic. That means it will not resist thermal breakdown as well in extended hard riding, but for a stock ADV 160 used for commuting and light touring, it is more than adequate. And it is the only option here that is a genuine Honda part.
Why choose the OEM
- Genuine Honda oil — exact spec for your ADV 160’s warranty requirements
- 4-quart pack is priced well for multiple changes
- Shear-stable polymer additives resist viscosity breakdown as designed
Where it falls short
- Mineral base lacks the high-temperature film strength of semi or full synthetics
- May not deliver the shift smoothness some riders prefer — some owners switched to Motul for that reason
Best for the “low-maintenance” buyer: you want Honda’s own formula in the jug with zero spec stress.
Not for you if: you ride hard in hot climates or want the tactile improvement of a synthetic shift feel.
3. Motul Scooter Power 4t Motor Oil – 5W-40 – 1L
A full-synthetic 5W-40 built specifically for scooters with high-performance engines that run hot and hard.
This Motul Scooter Power is a 100% synthetic oil with an SAE J300 viscosity grade of 5W-40. The “5W” part means it flows more easily in cold starts than a 10W-30 oil. The “40” hot-rating means it keeps a thicker protective film at high operating temperatures compared to a 10W-30 oil — useful if you ride your ADV 160 hard on long stretches or in a hot climate. Its container type is a 1-liter bottle, and it weighs just 0.85 Kilograms.
The product is formulated for high-performance engines, with improved high-temperature deposit protection and sludge control. It also offers high lubricating properties that decrease friction and wear, increasing engine lifetime. Buyers who have used it in Vespa Sprint 150 and Piaggio Fly 150 scooters report it works well with no complaints — one said “All I use. I have used this oil for a long time and am very happy with its performance.” For the ADV 160, the 5W-40 rating gives you broader temperature coverage than a standard 10W-30.
Compared to the Motul 5100 (10W-30), this oil uses a 5W-40 grade instead — which is a 2x gap in the cold-viscosity number — offering better cold-flow plus a thicker hot film. The trade-off is volume: you get only 1 liter versus the 5100’s 4 liters, so you will need to buy multiple bottles for multiple changes. Also, the 5W-40 viscosity may differ from your ADV 160’s manual recommendation — always check before switching.
Why it stands out
- 100% synthetic base for maximum thermal stability and deposit control
- 5W-40 viscosity flows better in cold and protects better in heat than 10W-30
- Built specifically for scooter engines, not adapted from motorcycle oil
Consider before buying
- Only 1 liter per bottle — you will need multiple for more than one change
- 5W-40 may not match your ADV 160’s specified viscosity — verify in your manual
Pick this if: you ride your ADV 160 in varied climates or push it hard on long days — the wider viscosity range gives you a safety buffer.
skip it if: your ADV 160’s manual strictly calls for 10W-30 and you do not want to deviate from that spec.
4. ULTRA 1PLUS 4T 10W-40 Motorcycle Oil Synthetic Blend
A JASO MA2 gallon jug at a price that makes multiple oil changes painless.
The ULTRA 1PLUS 4T is a synthetic blend 10W-40 motorcycle oil that carries JASO MA2 certification, so it is safe for your ADV 160’s wet clutch. The SAE J300 viscosity grade is 10W-40 — one step thicker at operating temperature than the 10W-30 most ADV 160s specify. The flash point is 215 Degrees Celsius, which trails the Motul 5100’s 228 Degrees Celsius by about 6% — still a respectable safety margin for most riding conditions. The container is a 1 US Gallon jug, giving you roughly four oil changes for the ADV 160 (at about 0.9 quarts each).
The product is formulated to reduce internal friction and protect against engine wear, helping extend engine and component life. It is also engineered for all-season 10W-40 performance, with dependable protection in both high and low temperature environments. Owners mention it is a “good product for the price” and that “this JASO oil is what is recommended.” One owner running a Yamaha FJR1300 said it was “pretty high grade bike oil.” For an ADV 160 owner who wants a JASO MA2 oil at a lower per-change cost, this gallon jug delivers.
Compared to the Motul 5100 (4 L, 10W-30, 228°C flash point), the ULTRA 1PLUS uses a 10W-40 viscosity and a 215°C flash point — the Motul has a 13°C higher flash point, which means better resistance to oil breakdown at extreme temperatures. The ULTRA 1PLUS also comes in a gallon jug (128 oz) versus the Motul’s 4 L jug (135 oz), so the volume is very similar. If you value the higher flash point and Ester technology of the Motul, pay the premium; if you want a JASO MA2 oil that does the job at a lower cost, this is your pick.
What works well
- JASO MA2 certified — safe for your ADV 160’s wet clutch
- 1-gallon jug is cost-effective for multiple changes
- All-season 10W-40 formulation covers a wide temperature range
Where it lands behind
- 10W-40 may be thicker than the ADV 160’s recommended 10W-30 — check your manual
- Flash point (215°C) is lower than the Motul 5100 (228°C)
Grab it if: you want a JASO MA2-certified synthetic blend in bulk for the lowest possible cost per change.
Walk past it if: your ADV 160’s manual calls for 10W-30 specifically and you do not want to run the thicker 10W-40.
Understanding the Specs
JASO MA2 Certification
This is the friction standard for 4-stroke motorcycle oils used in wet clutch systems. A JASO MA2 oil provides the exact friction characteristics needed so the clutch plates grip without slipping and release without dragging. An oil without this rating — like standard car oil — can cause clutch chatter, slipping, or hard engagement. Every oil in this guide is JASO MA2 certified.
SAE Viscosity Grade (10W-30, 5W-40, 10W-40)
The “W” stands for winter and is the cold-flow rating; the number after it is the hot operating viscosity. A 10W-30 flows well in cool weather and thins appropriately when hot. A 5W-40 flows even better in the cold while staying thicker at high temperatures. Your ADV 160’s owner’s manual tells you which grade to use based on your local climate. Using the wrong grade can affect cold starts, fuel economy, and engine wear.
