The CRF450X has a reputation for using oil when ridden at higher RPM's, but not anymore.   I would also like to mention that both the crankcase and the transmission oil hold their clarity longer than previous oils I've used, including other synthetics. AMSOIL will definitely be my oil of choice from this point forward   Sincerely, Kris McDonald #257x AMSOIL Products Used by Kris: MCF 10W-40 Motorcycle Oil Click Photo for Larger Image	PRODUCT LOOKUP GUIDES Auto and Light Trucks PowerSports Lookup Small Engine Lookup TRICO Heavy Duty FILTER LOOKUP GUIDES Vintage Vehicle Heavy Duty Lookup PERFORMANCE TESTS View Results CROSS REFERENCE GUIDES Master Filter Cross NGK Plugs and Wires INSTALLATION INFO By-Pass Filters WIX Cabin Air Filters MANN Cabin Air Filters MISCELLANEOUS Drain Interval Chart Gear Lube Chart Two-Cycle Chart MSDS Sheets Tech Service Bulletins
