Motul 5100 10W-40 4T Engine Oil (Technosynthese® Ester) – JASO MA2 (2023) API SP – 1L / 2L / 4L

If your bike needs SAE 10W-40 with wet-clutch safe JASO MA2, this is one of Motul’s most trusted daily + touring oils—smooth shifting, strong protection, and consistent performance across the drain interval.

Motul 5100 10W-40 4T is a premium Technosynthese® motorcycle engine oil reinforced with Motul Esters, formulated for 4-stroke bikes with wet clutch and demanding everyday riding—city traffic, touring, and weekend rides. It meets API SP and JASO MA2 (2023) standards, helping ensure reliable clutch grip, smoother gear shifts, and strong film strength for engine longevity.

What most sellers don’t explain clearly: 10W-40 is a grade choice, not a “better or worse” oil. You should use this only if your owner’s manual recommends 10W-40 (or allows it in your temperature range). If your bike specifies 10W-30 / 10W-50 / 20W-50 or JASO MB (scooter oil), do not switch blindly—wrong grade can affect starting, heat protection, and clutch feel.

Pack sizes available: 1L, 2L, 4L (select variant).

FAQs 

Q1. Is this oil safe for wet clutch motorcycles?
Yes. It meets JASO MA2 (2023) which is designed for wet clutch compatibility and controlled friction.

Q2. My bike currently uses 10W-30. Can I upgrade to 10W-40?
Only if your owner’s manual allows 10W-40 for your climate/usage. If not listed, don’t switch—use the OEM-recommended grade.

Q3. Does this oil meet API SP?
Yes—API SP is listed for this product.

Q4. Is 10W-40 good for high heat and traffic?
10W-40 is commonly chosen for mixed city + highway where the bike runs warmer, but the “right” grade is always the one your manual specifies.

Q5. What is Technosynthese®?
Motul uses this term for a premium technology blend formula; this product is reinforced with Motul Esters for durability.

Q6. How long can I run this oil?
Drain interval depends on your OEM/service schedule; Motul notes protection over the drain interval, up to 16,000 km depending on OEM. Always follow your motorcycle manufacturer’s recommended interval.

Q7. Is this suitable for scooters?
Only if your scooter manual specifies JASO MA/MA2 and a wet clutch (rare). Most scooters need JASO MB, so verify first.

Q8. How do I confirm authenticity?
Buy from a trusted seller, check packaging/label details, and keep the invoice. (You can add your own Under The Hood authenticity + QC steps here.)
