I've worked for various lubricant companies on a consultancy basis. They do actually go to a lot of trouble to tailor oils for different uses.ErikGustav2 wrote: ↑Sat Dec 04, 2021 9:56 pmIt was a long time since I read so much nonsense.Hugh wrote: ↑Wed Oct 13, 2021 9:39 pm Greetings,
Might it be worth getting in touch with Elf for their guidance

I think that motorcycle oil for bad weather takes first price
MOTO 4 CRUISE 20W50 – Flexible engine protection for 4-stroke engines.
MOTO 4 ROADSTAR 10W40 – Synthetic-based engine oil designed for faster acceleration and smoother ride.
MOTO 4 ROAD 10W40 – Synthetic-based engine lubricant designed for fewer start-up emissions, a more comfortable ride and protection from clutch slippage.
MOTO 4 ROAD 15W50 – A synthetic-based oil for superior motorcycle superior performance in bad weather, featuring anti-slip clutch technology.
MOTO 4 TECH 10W50 – Innovative synthetic lubricant for improved power, efficiency and engine cleanliness.
MOTO 4 MAXI TECH 10W30 – Next-generation synthetic oil that improves fuel economy, protects engines from wear and deposits and controls clutch friction, all while lasting longer.
MOTO 4 TWIN TECH 20W60 – High-tech synthetic lubricant designed for twin engines, ensuring smooth gear changes, engine component cleanliness and performance.
For example an oil for commuter motorcycles will need good cold-starting/protection properties, a long drain interval and protection against wear in stop-start conditions, plus reduced fuel consumption.
A race oil needs low pumping/churning losses, low friction properties, and a high film strength at extreme pressures and temperatures. A short drain interval is acceptable, as race engines get serviced/checked frequently. Stop-start protection is unimportant.
