Where to Use It

For 4-stroke motorcycle, ATV and UTV engines that call for this viscosity and a JASO MA oil. Check your manual for grade and capacity.

Buying Guide

Use these points to pick the right product:

• Viscosity: use the grade your owner’s manual lists for your engine and climate.
• JASO MA: needed for wet-clutch motorcycles so the clutch doesn’t slip.
• Line: Cross Power for off-road racing, Power Synt for sport bikes, Top Speed for all-round street use, Boxer for BMW Boxer engines, Formula for a semi-synthetic option.
• Quantity: check your oil capacity; a 4 liter jug covers most single and twin oil changes with a filter.

How to Use It

Warm the engine, drain the old oil, replace the filter and refill to the level in your manual. Check the level after a short run.

Pro Tip

Write the date and mileage on the filter or in a log so you never miss an interval.

Signs It’s Time for an Oil Change

• You’ve reached the interval in your manual
• The clutch feels grabby or slips
• Oil looks dark or smells of fuel
• Before storage, so acidic used oil isn’t left in the engine

Storage and Safety

Store containers sealed, upright and away from heat, sparks and children. Wear gloves when handling oils and solvents, use aerosols in a well-ventilated area, and dispose of used fluids at a recycling center.
