It's currently very hot in Cairo, decided to take the scooter for my daily commute. M1 5W40 was in sump before I picked Delvac MX III 20W50. Extreme day temperature around, air-cooled engine, heavy traffic, dusty air, etc. So I need the extra ZDDP and TBN. Before I had good 75 MPG on 0W40 or 5W40, nothing outstanding for a 150cc engine. Now I'm getting a whopping 120 MPG.. wait a minute! What?
20W50? stout HT/HS ? 20W50 saving fuel? In 8 years having this scooter I've never seen fuel mileage better than 80-85 MPG.
