Motul 4100 Syn-nergy 15W-50 Technosynthese Engine Oil - 1L

Motul 4100 Syn-nergy 15W-50 is a Technosynthese engine oil for cars running gasoline or diesel engines, with the heavier 15W-50 grade aimed at mid-age and higher mileage engines where keeping oil consumption in check matters. It is rated ACEA A3/B4 and API Performance SP. The thicker hot film supports engines with more wear and clearance than a new unit, and the additive package targets continuous protection across long service intervals.
